Update 1: Please do not confuse Galaxy S4 screen mirroring with Android screen mirroring through Chromecast. Android screen mirroring (screen cast) is also supported on Galaxy S4.
Update 2: For detailed comparison of Chromecast and Miracast, please check this guide.
You may not know you can enjoy any contents in your Galaxy S4 in a bigger screen (e.g., TV). You can simply share the Galaxy S4 screen with most TVs or even some projectors.
This is Galaxy S4 screen mirroring.
Some geeks may call it wireless display, which is used by some other vendors.
Galaxy S4 Screen Mirroring is one of the prominent features in the smartphone. But unfortunately, this feature is under-used, because there are no clear guides for Galaxy S4 owners on how to use screen mirroring in Galaxy S4
This ultimate guide of Galaxy S4 screen mirroring will solve the problem for you.
Everything you need to know about Galaxy S4 screen mirroring will be covered. I will update this guide regularly. If you have any questions or suggestions, please leave them in the comments section below.
What is Galaxy S4 screen mirroring?
Galaxy S4 screen mirroring (or wireless display) simply duplicates the display in your Galaxy S4 on TV or other bigger screens (e.g., projectors). In other words, instead of staring at the 5″ screen, you can share Samsung Galaxy S4’s screen with TV of any size. The Samsung Galaxy S4 then works like a remote control for your TV.
This means you can consume any contents from your Galaxy S4 on a TV with a bigger screen with screen mirroring. For example, you can watch any videos on the TV screen from Galaxy S4. This usually gives better watching experience. You can easily share the video or the show with your family members in the living room with a bigger screen.
With Galaxy S4 screen mirroring, you can also play games on your TV screen. Your Samsung galaxy S4 is your controller and the storage of your games. In other words, any games you can play in your Galaxy S4 can now be played on the TV screen. Isn’t it cool?
You can also use Galaxy S4 screen mirroring to show photos taken or saved in your smartphone on the TV for other family members or friends during a gathering. Everybody knows it is painful when there are 10 eyes staring at the 5″ screen. Now you can share the Galaxy S4 screen to a TV so that everyone can enjoy the photos.
Is only the screen mirrored? How about the audio?
Although so far I only use “display” or “screen” for Galaxy S4 screen mirroring, actually sound/audio will also be mirrored (to be precisely, transferred). Galaxy S4 Screen mirroring is not just for mirroring the screen ( screen sharing ): it shares and casts both display and audio to your TV.
If you have a good sound system for your TV, you will immediately enjoy the excellent audio through Galaxy S4 screen mirroring. You will probably never want to watch movies in your Galaxy S4 at home any more. The sound quality is limited by the video file itself and your sound system, not by your Galaxy S4 (although the audio quality of Galaxy S4 is not bad).
In fact, Galaxy S4 Screen mirroring never degrades the audio quality.
The technology behind Samsung Galaxy S4 screen mirroring
Galaxy S4 screen mirroring uses the technology called Miracast, which allows a portable device or computer to send, securely through peer-to-peer WiFi Direct connection, up to 1080p HD video and 5.1 surround sound, to any devices that support Miracast.
Galaxy S4 (including most of its variants) is Miracast-certified. Galaxy S4 screen mirroring complies with Miracast standard. This implies, for screen mirroring, Galaxy S4 works with all Miracast-certified devices.
Miracast is officially supported by Android for Jelly bean 4.2 and later versions. Google and most other Android phone manufactures use the term wireless display (e.g., Wireless Display in Moto X). , which is essentially the screen mirroring in Samsung Galaxy S4.
Before Miracast is officially supported by Android, Samsung supported Miracast through their proprietary implementation of AllShare Cast. You can find this option in some old flag-ship phones, for example, Galaxy S3, Galaxy Note 2, Galaxy Note 10.1. Galaxy S4 Screen mirroring is a natural evolution of AllShare Cast and Android’s wireless display.
If you used AllSahre cast in some Samsung device before, Samsung Galaxy S4 screen mirroring is actually not new at all. All devices works with AllShare Cast should work perfectly with screen mirroring in Galaxy S4.
How to turn on and turn off Samsung Galaxy S4 screen mirroring
To turn on Samsung Galaxy S4 screen mirroring is very simple. you just go to Settings–Connections–Screen Mirroring (maybe slightly different depending on your region). Drag it to right to turn it on. Drag it left to turn Galaxy S4 screen mirroring off (stop sharing screen).
Once Samsung Galaxy S4 screen mirroring is turned on, Galaxy S4 will then scan for available devices that support Miracast within the range. Tap that device to connect to it following the on-screen instructions.
So you need another device, usually a Miracast-supported TV, or a Miracast-supported HDMI dongle, to get the mirrored screen. Please read on to know what you need.
What are required to use Galaxy S4 screen mirroring?
Miracast is an industry-wide solution, so the technology works well across devices, regardless of brand and vendor.
To use Samsung Galaxy S4 screen mirroring, you only need a Miracast-supported TV. Your Galaxy S4 will immediately find your TV once the screen mirroring is enabled. So, you can share your screen on the TV immediately after you start the Galaxy S4 screen mirroring. Most smart TVs released in last two years support Miracast. You may check the specifications of your TV.
It is NOT a problem, even if your TV does not support Miracast. A HDMI port is the only requirement for your TV.
If your TV is not a smart TV or it does not support Miracast, you can get one of the following devices to make Galaxy S4 screen mirroring work for you:
- HDMI adapter that supports Miracast
- Samsung HomeSync
- Samsung AllShare Cast Hub
Now, let’s explore these 3 options to help you decide the most feasible solution for your Galaxy S4 screen mirroring.
Miracast-supprted HDMI Adpater for screen mirroring
There are quite a lot Miracast-supported HDMI Adapters in the market. Most of them will work with Galaxy S4.
But not all of these HDMI adapters are created equal. The latency or the lagging is usually your primary concern. Some low-quality adapters may cause considerable lags when sharing the screen. Sometimes, the video and audio are even not synced. This will surely ruin your watching experience.
Another factor you need consider is whether you want to use screen sharing or wireless display for other devices.
Based on my own experience, I usually recommend Netgear Push2TV Wireless Display HDMI Adapter with Miracast. It works for all of my devices. This adapter works well with Samsung Galaxy S4 screen mirroring. When using it for Galaxy S4 screen mirroring, you will not feel any lagging. The audio is synced very well as well.
This adapter is extremely useful if you have some non-Samsung smartphones or tablets at home, especially, Amazon Kindle Fire HD or Kindle Fire HDX tablets. It is even officially certified by Amazon for display mirroring with Kindle Fire HDX 7, Kindle Fire Hdx 8.9 and the new Kindle Fire HD. So, it is a good idea to get this adapter to enjoy Galaxy S4 screen mirroring or Kind Fire display mirroring . It works with most other Android phones with Jelly Bean 4.2 or newer as well, for example, Galaxy Note 3, HTC One, Nexus 4 and Moto X.
This adapter also supports Intel Wireless Display (WiDi). This means you can use your TV as the second screen for your WiDi-supported laptop with this adapter.
The price for this adapter is around $60. In the box, the USB power adapter is included. But surprisingly, HDMI cable is not include. When ordering this adapter, please make sure you get a HDMI cable if you do not have any spare cables at home.
Samsung HomeSync for Galaxy S4 screen mirroring
Samsung HomeSync is actually a personal cloud (1TB) with tons of features. Screen mirroring is only one of the features in the long, long feature list. For Samsung Galaxy S4 screen mirroring, this device is actually overshot.
HomeSync is recommended when you also need personal storage cloud to save and share videos, music, and photos. It can also be used as a media player for your TV.
Most Galaxy phones and tablets are supported by HomeSync. But screen mirroring is only available on Galaxy S3 (and some variants), Galaxy S4 (and some variants), Galaxy Note 2, Galaxy Note 3, Galaxy Grand, Galaxy note 10.1, Galaxy note 10.1 2014 edition, Galaxy Note 8.0, Galaxy Tab 3 (7.0, 8.0 and 10.1) . To fully utilize the HomeSync, you need download the free HomeSync app.
The HomeSync is not cheap. It will cost you around $300 (1TB).
Samsung AllShare Cast Hub for Galaxy S4 screen mirroring
Samsung All-Share Cast Hub is another affordable solution if your TV does not support Miracast. The wireless adapter works with Galaxy phones with AllShare Cast capability. Of course, Galaxy S4 screen mirroring is officially supported.
Please note, this AllShare Cast Hub is only for Samsung devices. It works nicely for Galaxy S4 screen mirroring without any configurations. If you have some non-Samsung smartphones or tablets, it is better to get the Netgear Push2TV Wireless Display HDMI Adapter mentioned above.
How about Google Chromecast? Is it work with Galaxy S4 screen mirroring?
The $35 Google Chromecast is an exciting, and affordable device. But at this time, Miracast is NOT supported by Chromecast. So, it can NOT be used as an adapter for Galaxy S4 screen mirroring.
With the Chromecast dongle, what you can cast on your TV from Samsung Galaxy S4 is limited by the apps that support Chromecast. Anyway, this is not through screen mirroring.
Troubleshooting for Galaxy S4 screen mirroring
Here are list of commonly asked questions on using Galaxy S4 screen mirroring. I update the list regularly. If you have any other questions, please post them in the comments below, or use contact us page to let us know.
Q1: I turned on Galaxy S4 screen mirroring, but there are no device found to share the screen.
A1: Make sure your TV is on. If you are using an adapter, make sure the HDMI source is set correctly on your TV and you can find some texts like ready to cast on your TV.
Q2: Should the smart TV (or the HDMI dongle/adapter) connect to the same network as Galaxy S4 for screen mirroring?
A2: No. For Galaxy S4 screen mirroring, a peer-to-peer wireless network between the TV (or the adapter) and Galaxy S4 will be established privately to share the screen. This is independent of other wireless connections. Actually, internet access is not a pre-requisite for Galaxy S4 screen mirroring. This is different from Google Chromecast.
Q3: How about Galaxy Note 3? is this guide applies to Note 3?
A3: This guide also applies to Galaxy Note 3. You may check this page for more specific issues on screen mirroring on Galaxy Note 3.
Q4: Can I turn off the Galaxy S4’s display when using Galaxy S4 screen mirroring?
A4: No, you cannot. If you turn off the display on Galaxy S4, nothing will be shown on the TV. TV simply duplicates whatever you have on the screen of S4. To save battery when using screen mirroring, you can disable auto brightness and set a low value of brightness. For brightness settings, you may check this page.
Q5: Will the brightness or other screen setting on Galaxy S4 affect the TV when using Galaxy S4 screen mirroring?
A5: No. screen or display settings in S4 are only for Galaxy S4. TV will use its own settings as explained in your TV’s manual. They are independent of each other.

February 16, 2014 at 11:45 pmHi, I have the Samsung Galaxy S4 mini and I also have the Netgear Push2TV PTV3000. I also have a home theater/surround sound system from Sony. I have used wireless display and miracast before and connect my laptop via WiDi on a regular basis. I am able to connect my S4 mini and the quality is phenomenal. The issue I am having is with the sound. I have sound but the quality is poor and no bass, all treble. It sounds like the system is set to monaural even though it is not. When my laptop is connected the sound is pristine. I assumed that the phone was incapable, but I have a friend that has a Motrola Moto X and his phone was able to play sound perfectly and as good as the laptop. I believe that all the settings on the surround sound receiver are correct, because I have not changed anything and my laptop works and the Moto X worked all with the same settings. I have read most of your tips and guides and I have tried different sound sources and they all came through poorly. Again sound sources from youtube, netflix,music stored on the device, spotify, soundcloud etc. work flawlessly when using the Moto X and my laptop. I have tried additional sources, but I do not believe it is the source of the sound or my surround receiver. Do you have any suggestions for me? I appreciate any help.
Thank you,
Michael
simon says
February 17, 2014 at 1:00 pmIt could be due to the specs of S4 mini. For S4, I never got any issues.

April 14, 2014 at 7:20 amThanks for your answer Simon, this information is good to know.
Would you know about an app that could turn the tab into a “receiver” ?
thanks 🙂
simon says
April 14, 2014 at 10:12 amNot sure. Normally smartphones or tablets are considered as small screen so they seldom act as receivers.
Samsung has group play (the new one, not the old one) that can partially (limited) share the screen among Samsung devices. But it does not work on your devices. It needs S4 or later models. And it doesn’t work well.

simon says
July 26, 2014 at 1:47 amit is a hardware implementation, not just software, as I know. So far, I don’t know any laptops for this. Most laptops are senders (e.g., WiDi).

Please mail the info
Sorry
simon says
April 26, 2014 at 3:54 amIt depends on what you want to achieve.
For screen mirroring, it is better to get a Mircast adapter (and the HDMI cable to connect it to the TV). You can mirror everything on your S4 to the TV. Netgear PTV 3000 works very well.
If your main usage is streaming, or even casting from your home PC, Chromecast is another option. You may check this guide: http://allaboutchromecast.com/chromecast-vs-miracast-everything-you-need-know-about-wireless-display-and-screen-mirroring/
Please understand the limitations of Chromecast. It is not a replacement for Mircast adapter. They work differently.

April 26, 2014 at 5:57 pmI have the s5 and a newer Samsung tv. The TV has allshare and has my phone under screen share as allowed. When I hit screen mirror the s5 scans but can’t find my tv. Any suggestions?
simon says
April 27, 2014 at 4:24 amDid you check the settings on the TV? It usually is located at: MENU > Network > Screen Mirroring (it may be slightly different on different TVs)
NEW!! Facebook page || Android Guides || Chromecast Guides || Galaxy S6 Guides || Galaxy S7 Guides || Galaxy S8 Guides || Galaxy S9 Guides || Google Home Guides .
david says
April 27, 2014 at 5:46 amYes. The TV recognizes the galaxy, the galaxy scans but doesn’t see the tv.
simon says
April 27, 2014 at 1:50 pmIn other words, TV can scan and find your phone, but your phone cannot find TV. This is a bit strange.
Anyway, I still think it is probably related to some settings in the TV, not on the phone (on which you just need enable wifi).

david says
April 27, 2014 at 2:15 pmYes exactly. I see the model number of the galaxy on the tv but when I hit screen mirror on the phone it scans and finds nothing.
Susan Rand-Lakritz says
April 29, 2014 at 3:27 pmI have a Blaupunkt New York multimedia system in my car. I just had a Carphone unit with Miracast installed so that the gps app Waze could be mirrored onto the built-in screen. Besides having some difficulty in having the cell scan and find the Miracast (I’ve even had to restart the phone to get it to work) the bigger issue is that screen mirroring suddenly turns off. Why is this happening and what can I do to prevent it?
Thanks,
Susan
simon says
April 30, 2014 at 1:36 pmMiracast is still new. The hardware compatibility and performance are still among some big issues with this technology.
When you purchase such devices, you need check with the vendor whether the pair can play together nicely.

Susan Rand-Lakritz says
April 30, 2014 at 3:15 pmOur Honda dealer knew that I wanted to mirror Waze onto the Blaupunkt system. The Blaupunkt system was also offered and installed by the dealer. The dealer supplied and installed the Miracast unit. We were their first customers for it so I’m sure there was a bit of a leaning curve. They weren’t much use in explaining how to use the system.
It seems to me that the unit has 2 modes: Miracast and something else that has 4 letter and starts with a “D”. I’m still trying to figure out exactly how to get to the Miracast setting because it doesn’t always come up.
Another thing that I’m not happy about is that the mirroring unit was plugged in to the AV-2 setting on the Blaupunkt system. When I’m mirroring nothing beside the Bluetooth phone function works – no radio, no MP3, etc. The only way I can listen to music is to get it through the cell phone. Not ideal. If I had know this I’m not sure I would have installed the mirroring unit in the first place. Is there another way it could have been installed so that the mirroring runs in the background and I can still listen to music?
Thanks,
Susan
simon says
May 1, 2014 at 3:36 amI’m not familiar with the system. Maybe, such a feature (simultaneous miracast and radio) is not supported. Anyway, the dealer may have more knowledge on the capabilities of the system.
In Galaxy S4, screen mirroring simply transfer the display and audio to the Miracast-enabled device (receiver) through local WiFi network created by the Mircast-enabled receiver. You should be able to play music on S4 when screen mirroring is active.

simon says
May 1, 2014 at 3:47 amIt seems Samsung didn’t update the firmware for HomeSync for long time. But it should still work with GS4 after kitkat update. Did you update your HomeSync app, and Samsung Link app on your GS4?

May 3, 2014 at 2:40 pmI’ve got the Netgear Push2tv and a Samsung Galaxy S4 mini. I can connect the 2 with my phone but it won’t go any further. It doesn’t properly connect and then the screen mirroring turns off. I’ve tried the firmware update but still not working. Any ideas?
simon says
May 4, 2014 at 3:23 amScreen mirroring need two components: a sender (your Galaxy S4 or Galaxy S4 Mini) and a receiver (Netgear Push2TV). You cannot mirror one phone screen to another because both are senders only.
Anyway, the normal usage is your plug the Netgear to your TV, then in your Galaxy S4 mini, go to Settings → Connections → Screen Mirroring, and then drag the Screen Mirroring switch to the right. Your Galaxy S4 mini should search for devices in range and should discover the Netgear.

May 6, 2014 at 10:01 amYou may try to check whether there are any updates for your phone and TV. For the phone, you need check both system update and Samsung apps update.
If no updates, you can try to reboot your phone and try again. Normally,after one failed connection, you should reboot your phone before trying again.

What do you mean by “reboot” – restart? if yes, I have already made it, unfortunately no success.
Please advise
simon says
May 6, 2014 at 11:09 amYes, reboot just means restart.
You can check whether there are any firmware updates from Setting–general–about device–software update–update.
You can check Samsung apps update by start the Samsung apps.

simon says
May 6, 2014 at 1:42 pmNot sure. Probably you rooted or manually flushed the rom before.
If your S4 always drop connections, it could be due to some firmware issues. Unfortunately, there are no obvious ways to test. You may check whether your S4 can connect to other Miracast-enabled devices.

May 26, 2014 at 3:35 pmCan I stream the directv app on my S4 to a allshare tv? For example, I have a TV set up without a directv cable box but have an app on my S4 to stream live directv.
simon says
May 26, 2014 at 11:56 pmIf you can watch the programs on your s4, then, yes, very likely, you can mirror what you can see and hear to the TV.
Screen mirroring is local mirroring and is not streaming. You have to use your s4 to connect to the service provider, screen mirroring mirrors your s4 (display and sound) to the TV. This means you cannot use your phone for other jobs if you are watching the TV.

June 20, 2014 at 10:19 amHi all,
Small question, I have S5 and Samsung smart 5300 TV… same lan, both connected, I can see TV in allowed devices on mob, and can see mob on TV, but.. I can’t share/see image from S5 on TV screen… When I first tried, everything worked well, but now, there is no way to reproduce picture on big screen… Any suggestion/help, please?! This is really annoying, due the fact that on my other phone, old Xperia P everything is working like a charm, without any additional setup…
simon says
June 20, 2014 at 10:54 amFirst, you don’t need network for screen mirroring.
In your S5, tap Settings–Screen mirroring. It will search for any nearby devices. That’s all.
Did you get any error messages on S5?

June 21, 2014 at 8:31 amit seems your TV does not have screen mirroring feature (Miracast). You may check with the vendor or Samsung support.
Most Samsung smart TV has AllShare Play. It can play contents from USB and DLNA devices (for example, S5). But it cannot mirror the screen.

June 30, 2014 at 5:29 pmHi…pretty niche article…However I am facing an issue I have a miracast supporting dongle and using S4 i9500 it gets connected but then shows an error HDCP not supported to the attached device.
Thanks!
simon says
July 1, 2014 at 1:26 pmThen, you have no choice. You got this error is due to the DRMed content.
You can try to unplug the dongle and re-connect it, but most of the time, it will not help.

July 6, 2014 at 4:23 pmevery time I turn off the screen mirroring feature by sliding the button to the off position, and re-check to see if it is off, the screen mirroring still remains on. Is there a way to shut it off where it remains off? And, can someone with another android see your text messages or pictures on their android via the screen mirroring feature? in other words, can your txt message screen be shared with another android from another location via the screen mirroring feature? Thank You…
simon says
July 6, 2014 at 11:56 pmYou should disconnect from the device first.
Normally, if should be turned off of you drag the slider to the left. It should not turn on automatically. If the problem persists, you may try to reboot the phone.
If the screen mirroring is active, you should see the notification icon. Most android devices are senders, not receivers, in other words, most of them can only send their screen, not displaying other screens.

January 3, 2015 at 11:21 pmI have the same problem as the June 6 writer. The screen mirroring will turn off, but when I recheck it it is back on. I brought it to verizon and they rebooted it, to no avail. I called galaxy who could tell me how to correct it. They sent me a new phone and it is still doing it. Any ideas on how to turn if off so it will stay off?
simon says
January 4, 2015 at 12:23 pmIt could be some bugs in the Galaxy S4 firmware. You can try to disconnect it from notification area, not just disable it.
Even if it is on, I guess it will not connect automatically. You need always manually choose the device (TV) to connect.

July 22, 2014 at 4:23 amThat’s a shame. I’m in the same situation. I have unlimited on my phone, and my kids have tablets with WiFi. I could broadcast a Netflix movie to their tablets on long drives (there’s one coming up).
This seems like a more reasonable use for Miracast than connecting to a television. I already have computers and cable connected to my screen–connecting my phone really doesn’t make sense (for me, at least).
This makes Miracast pretty useless. I’m looking into other possibilities such as MirrorOp.

September 6, 2014 at 8:30 amIs there a way, I can Mirror my S4 with another s4 or a samsung tab ??
simon says
September 6, 2014 at 1:23 pmProbably note, smartphone or tablet are usually designed as the sender, not receiver if Miracast is supported.

October 19, 2014 at 3:10 amHi
i have s5 and a dlibg dongle which support miracasr.
when i connect it to my tv is shows the devise in mirror screen but does not connect to it
it shows connecting for a while and then dies not connect at the end.
gaurav says
October 19, 2014 at 3:22 amCorrection: i have s4 and d-link device.
simon says
October 19, 2014 at 1:24 pmSo, your S4 actually can find the D-link dongle and tries to connect to it?
You may try to check whether there are any firmware updates for the D link dongle.
Does the TV screen change when s4 is trying to connect?

i have samsung galaxy s4 i9506 (LTE)
with the screen mirroring feature –
problem is – i try screen mirroring and i use Android dongle (which supports mira cast)
screen mirroring starts and continues for a while (for about 30 -50 seconds) and then stops and there is a note “mirroring has stopped” (or sth like this)
what could be the problem please?
thank you
Tony
simon says
November 2, 2014 at 1:20 pmSometimes, this is due to some task manager/antivirus apps (all of them are actually not necessary).
Another possible cause is the dongle. Try to get a branded one.
If you get the error, you may try to reboot the phone and try again.

November 14, 2014 at 12:16 pmI found another net gear ptv1000 is it the same? It was only 10 bucks
simon says
November 15, 2014 at 3:51 amIt is a very old old device and it may NOT work with Galaxy S4. PTV1000 is mainly designed for laptops (WiDi), not for Android.
I would suggest you to get PTV3000 (which is now usually less than $50 in Amazon now).
If you are using S4, S5, Note 3 or Note 4, you can use Chromecast to directly mirror the screen. Chromecast now usually costs less than $30 in Amazon and many apps support it. You may check the list of supported Android devices for Android screen mirroring here: http://allaboutchromecast.com/screen-mirroring-with-chromecast/

November 15, 2014 at 10:51 pmWell I have the s4 mini with the screen mirror option and I want to mirror movies from the phonw to tv. Chromecast can do it
simon says
November 16, 2014 at 7:34 amScreen mirroring through Chromecast is available in s4 (with kitkat 4.4 update) but not s4 mini. You need the support from individual apps.
So miracast probably is a better solution for you.

November 27, 2014 at 4:58 amI question… when mirroring I get video but no audio. Any solution you got in mind??
simon says
November 27, 2014 at 10:03 amYou may try to start screen mirroring first, then start to play.

simon says
November 29, 2014 at 10:09 amYou may try to reboot the phone. The problem probably is due to other apps.

March 10, 2015 at 8:30 amI have a galaxy s4 and wanted to mirror with another galaxy s4 is that possible? I turn them both on but says no device found
simon says
March 10, 2015 at 10:30 amNo, both are senders fir screen mirroring. Galaxy s4 and most mobile devices can only be used as senders.

September 5, 2015 at 3:47 pmHi, I wanted to know how to turn off the screen mirroring because my phone doesn’t have the on/off switch.
simon says
September 8, 2015 at 12:57 amOn the quick settings, there is an icon for screen mirroring. You can toggle it on and off to turn it on or off.

September 2, 2016 at 4:37 pmi have s microsoft wireless display adapter that i thought would work with my galaxy tab 4 but doesn’t. do you know if the S4 will work with this adapter? thanks
simon says
September 7, 2016 at 1:29 pmIs it based Miracast? Anyway, Microsoft products may not follow standards well.

September 8, 2016 at 9:03 pmHi. I am planning on purchasing a galaxy s4 and would like to connect it to my tv so I can watch netflix or showbox. .it is not a smart tv but does have hdmi..I do not have wifi at home but have a hotspot on my cell..is it possible to do this using the mhl cable?
simon says
September 11, 2016 at 11:55 amIf you user MHL cable, it’s not necessary to use hotspot. Your Galaxy S4 can mirror everything from the phone to the TV. MHL cable connects TV and Galaxy S4 directly.

February 1, 2017 at 5:00 amI have a galaxy s4 and connect to my samsung smart TV but there is no audio help!
Checked everything twice and it still isn’t working?!
simon says
February 1, 2017 at 10:22 amDid you try different contents, for example, playing video saved in your phone? YouTube sometimes may mute the playing when on Miracast. But you can manually turn it on by adjusting volume when video is being played.

February 1, 2017 at 10:49 pmI’ve tried going to Hulu, YouTube and other sites trying to see if it was just Hulu or something but it’s all of it phones up not on mute as well as the TV and the videos. I’ve tried going into my TV settings but I still haven’t figured it out
simon says
February 2, 2017 at 12:09 amFirst, you stop screen mirroring. Play the video on the phone and make sure you can hear the sound from the phone. Then start mirroring without stopping the playing.

April 30, 2018 at 1:17 pmI have used my Samsung s4 screen mirroring before with no issues, but now all of a sudden the audio no longer works & I can’t figure out how to fix this, any ideas? I tried the information above, but still nothing.
simon says
May 1, 2018 at 11:45 pmYou can try to reboot the phone to see whether it helps.
