Widescreen Monitor Not Working with Windows 10 RRS feed

  • Question

  • I have the LG 34" UltraWide Curved Monitor (Model: 34UC97-S).  Here are the monitor specs: 

    • 34-inch
    • In-Plane Switching (IPS) display
    • 21:9 Quad High-Definition (3,440-by-1,440) resolution

    I recently upgraded from Windows 8.1 to Windows 10 on my Surface Pro 3.  I'm having issues with audio and video playback on monitor.  Audio doesn't play through monitor speakers and streaming video, e.g. YouTube, sputters.

    I’ve tried different browsers (Chrome, Edge, and Firefox).  I've tried using my mini display port connection to the Surface Pro docking station and directly to the Surface Pro 3.  I’ve changed ports on the back of the monitor.  The result is the same – no audio playback and video sputters.

    LG Support says the monitor is "plug-and-play" so its Microsoft’s issue to figure out.

    The Surface Pro 3 worked flawlessly with the monitor when on Windows 8.1.  Also, I have another PC on Windows 7; it works perfectly with the monitor.

    Anyone else having issues with this monitor and Windows 10?  Or with other widescreen monitors with similar specifications?

    So a proper driver update is not released yet.

    Seems we have to wait for the driver. Sorry for the inconvenience.

  • I have the same issue - Lenova Yoga Pro 2 and a Hanspree Plug and Play 23" Monitor. Worked well with 8.1 - Windows 10 will not detect it. I updated the Intel video driver just in case - but not a  solution. I have read this also on a number of other sites - Microsoft - can you issue a fix?

  • I have the same issue but with a Samsung 24" monitor SyncMaster T240HD.

  • I’ve been on a call with Microsoft Support and I went to the local Microsoft Store.  Apparently, this is a unique issue with my Surface Pro 3.  Other Surface Pro 3's in the store didn't have this issue.

    The audio doesn’t work to any external monitor and the video stutters to any external monitor.  Viewing and listing to audio on the Surface Pro 3 is a non-issue.  Microsoft Store confirmed my firmware and drivers are all up to date. 
    Right now, my options are:

    1. Roll back to Windows 8.1 (where everything worked perfectly)
    2. Reset Windows 10 to see if that resolved the issue (I will have to reinstall all third-party software and re-do all of my settings)
    3. Wait for Microsoft to issue patches that resolve the issue

    Let me know if you guys find a fix.  I'll keep you posted on my end.

  • Chalk this up to "interesting".  If I plug my Surface Pro into external speakers while plugged into an external monitor, the video never stutters.  Go figure.

  • Hi,

    As it is a mini displayport, when we connect a Surface to monitor, the sound comes from that port means from display card.

    When we connect to an external speakers, I assume you are using a headset jack which means the sound comes from sound card.

    So in current situation it is still the display card which works improperly and cannot provide sound via mini displayport (I assume you have a mini displayport to HDMI converter).

    First please check if it is the default audio device was selected incorrectly. Go to Sound in Control Panel, test with each device in Playback to see if any one of them could make the monitor work.

    Also please test to upgrade the driver of your display card. You should able to find drivers on Microsoft website such as:

  • Shaon Shan:

    Your response makes sense.  Thanks for the info.  The display card is the one with the issue.

    I’ve tried several cables – a Mini DisplayPort to HDMI cable, a Mini DisplayPort to HDMI converter, and a Mini DisplayPort to DisplayPort cable.  All yield the same results.  It happens on any external monitors.

    The stuttering video also takes place whether I plug into the Surface Pro 3 dock (which I recently swapped out) and when I plug directly into the Mini DisplayPort on the Surface itself.

    I’ve tested the sound via Control Panel.  When connected to any external monitor, the external monitor shows up as a playback device and says it’s “Ready”.  However, the sound doesn’t play.  Yes, I’ve tried configuring.

    You’re correct.  This is almost certainly some sort of compatibility issue with the display card driver on my Surface Pro 3.  What’s interesting, though, is in the Microsoft Store other Surface devices work just fine with external monitors.

    Also, with the Surface Pro 3, both the operating system and hardware are owned by Microsoft.  The drivers are updated via Windows Update.  I can’t update the drivers on my own even if I wanted to.  (Yes, I tried.)

    Microsoft Support followed up with me yesterday.  The details of my issue have been logged and they say I should expect a fix to come (hopefully) in the next batch of Windows updates for Windows 10.  If it isn’t resolved then, I have to follow back up with Microsoft Support.

    Ah, the price of being an early adopter.  ;-)

  • Hi,

    Thank you for the reply. 

    As you also tried to contact Microsoft Support, whether they also think it is a driver related issue?

    It is a little strange if same devices in Microsoft Store works with Windows 10 - if acceptable I suggest you to do another test to uninstall your display card from the computer.

    After a reboot, it should use the default driver then. See if you can get sound in that situation.

    If still not, run Windows Update and I assume it should find a driver for your display card - if so, install it and again test if it will work.

    If still not, as you said we may have to wait for an update. I assume Windows 10 team is collecting information and ready for the first batch of updates as the support said.

  • Hi Shaon Shan, thanks for follow-up.  

    Yes, I tried uninstalling the Intel HD Graphics 5000 display driver via Device Manager.  The system acknowledges that I've uninstalled the driver but when I restart the machine, Windows never prompts me to update the driver.  Oh, and I can't manually update the driver since the Surface Pro 3 is a Microsoft machine (software and hardware) drivers can only be updated via Windows Update.

    Also, at the Microsoft Store we confirmed that the installed driver is current and aligned with the release of Windows 10 drivers used by a comparable Surface Pro 3 in the store that didn't have the issue.

  • Windows 10 does not see both my monitors but windows 8 did. How do I fix this please?

  • I'm having issues with a Philips widescreen monitor. Won't connect at all. Lost for ideas...
    Monday, August 10, 2015 4:11 PM
  • OK, so I had this issue too (with a widescreen Philiips monitor). Various blogs pointing to downloading new drivers / updates, etc but almost certainly, if you're reading this, you've tried this already (and besides, not sure how you update a monitor driver if the PC can't detect it in the first place).

    I was connecting my SP3 via Mini-Display Port to Display Port cable by Rankie. Thought I'd try a different cable, so bought a new Mini-DP to HDMI cable from Cable Matters and now I can connect with WINDOWS-P shortcut. So either it's a cable issue, or DP issue (I don't have another MiniDP to DP cable to check.

    When I called Microsoft, they said they were aware of the issue and expected a fix "soon" but the cumulative fix hasn't resolved it and as it's not being widely reported, I presume it may only be affecting a small number of people, and perhaps the cables do have something to do with it?

    Certainly, the new 'Cable Matters' cable was listed as being suitable for 4K feeds, whereas the other Rankin cable wasn't.

    Hope this helps?!

  • Thank you for the additional info, freetail.  

    After several cumulative updates to Windows 10, still no resolution to audio with external monitors with my Surface Pro 3.  Pretty disappointing since Microsoft is wholly responsible for both the OS and hardware on the Surface Pro 3.

    I'm trying to be patient here, but c'mon, Microsoft, this is your flagship device.

    Per my original remarks in this post, I've tried many cables; it's not the cables.  I've been to the Microsoft store and was able to replicate the issue there on every monitor they had me connect to.  When connecting to ANY external monitor, the video sputters and the audio doesn't work.

    The price for being an early adopter, I guess.

    Thanks everyone for providing info.  I'll keep providing updates until the issue is resolved.

  • Everyone on Thread:

    Today, Microsoft issued a driver update for Surface Pro display - Intel Corporation driver update for Intel(R) HD Graphics 5000.

    This may resolve the issue.  If you're on a non-Surface PC, look for the driver on Intel's site.

  • I changed the audio quality to 24 Bit (Studio-Quality), Sound is ok!

    Switching back to 16 Bit: No sound (like before).

    Set to 24 Bit again: Sound perfect!

    Reboot: Sound is still good.

    (Surface pro 3, Win10, LG Ultra-Wide, Displayport to Displayport, all up to date).

    Sounds strange, but this worked for me, hope this helps others too.

    You ROCK!  Worked liked a charm.  How in the world did you figure this out!?

    For those that want to try the same solution, here are the steps.

    1) Go to Control Panel
    2) Search for Sound
    3) Launch Sound dialog box
    4) On Playback tab, select monitor
    5) Click Properties button to launch monitor properties dialog box
    6) Select Advanced tab
    7) Using the drop-down, select ‘24 bit, 44100 Hz (Studio Quality)’ from drop down
    8) Click the Test button to hear sound play from monitor

  • I'm getting the exact same thing, with external (miniDP) display running audio to my LG 34" ultrawide. If I try to have the audio streaming to the LG, the audio doesn't work and the video stream is very jittery.  If I switch the default sound to the RealTek driver that's built-in to the Surface the video works fine on the LG. 
    Tuesday, September 15, 2015 5:28 PM
  • I still have the issue from time-to-time.

    If I use the widescreen monitor speakers right after a restart, it seems to work fine.  However, If I attempt to go from using my external speakers for audio to using the widescreen monitor speakers, I get the same issues detailed in this thread.

    I've had a couple of other glitches, including Surface Pro 3 screen not coming out of sleep mode even when the PC is "awakened".

    It's clear, this is a Windows 10 issue and they're still working out the kinks.  It's tough being an early adopter.

  • I have the same issue, I just switched back to win 8, the previous version I had.
    Monday, January 18, 2016 1:08 AM
  • I can't agree more - this is Microsoft's primary device to receive Windows 10 and this is still an issue, with no resolution from Microsoft and no commentary here from them.

  • I have been asking LG for assistance with my Wide Screen, 25um65, since I upgraded to Windows 10 from Windows 7 Pro on my desktop work station.

    Try this link:


    • I found some updates from LG for my monitor and for the software to create Screen Splitting for displaying more than one input at specific parts of my screen and I installed them
    • The updates work!  After rebooting my computer, the LG Wide Screen 25um65 monitor displayed beautiful fonts, and the Screen Split software showed  up on the notifications window and I tried it.  That worked too.
    • A word of caution:
          Uninstall your old Screen Split Software first
          Do not mess with your registry - LG's drivers and software were not there
          Ignore error messages related to the LG updates when you reboot

  • I am getting the same issue. I've had my Surface for over a year now, but the problem started a couple of months ago. Have you've been able to fix it since your last post?

    Friday, August 26, 2016 11:25 PM
  • I'm having the same issue. Your fix worked for me for 20 minutes. After that, the problem came back, and I can't fix it now. Have you've had the problem again? Did you find another solution?

  • My issue is similar to what Jose is reporting. Initially my LG widescreen was doing audio fine, but today it simply stopped (after I did some updates). Ulfs trick worked for a while to get my audio back, but after I made my LG the primary screen instead of my Surface Pro 3's screen;  the audio is gone again...

    sigh... I really wanted to be doing some video editing instead of this ^*&^^*& bug hunting...
