Windows 10: Video and audio out of sync with second monitor

Hi and hello, I have recently been having a problem with my video and audio whenever I have my second monitorTV plugged indoesn't need to be turned on via a HDMI cable. Sy browser based video and audio is out of sync, whether that is YouTube, Netflix etcetera, it all has the same problem. It will become out of sync. Sometimes it immediately become un-synced and somtimes it plays for a while like normal and then the problem occurs. And the even stranger thing is when second monitor isn't plugged in it has no problem at all! I have tried many fixes to this problem look at the list below bu

Audio Gradually Out of Sync with Video after Getting a Second Monitor

Hi,

I have used one monitor for a long time now and have never had any issues with audio. However, today I bought a new monitor and I'm now using it as my main with my old one beside it as a second monitor. Everything is working fine except when I play a game
on my main monitor and have a video or stream running on my second monitor then the audio and video gradually get out of sync. It has to be something to do with adding another monitor because it was fine when I just had one.

 

Audio Gradually Out of Sync with Video after Getting a Second Monitor

Hi mkerfers,

I did a little research about your issue and some users suggested to have the second monitor plugged into the motherboard rather than the GPU output so that it runs off the CPU's graphics.

Some advised that this case happens when sample rates of both audio and video are different, it will not sync or has the tendency to sync at the very beginning then slowly drift out.

For example, some content creators records their video first, then just adds the audio on the video. Now, if you record on a camera at 58,000Hz and you record the audio separately at 54,000Hz, it will of course deviate since both doesn't run at the same sample
rate.

Try the initial suggestion and see if that would sort the issue.

Another factor is to check the drivers. Normally, it should automatically sync it for you, but in some cases—depending on the make and model of your device, manufacturers offer driver software to freely configure this setting.

It may be possible that your desktop configuration is running separate sample rates for audio and video, but it's possible that the game settings are set to the matching sample rates so your audio doesn't drift out. But then again, you won't really notice if
it's not in-sync since during the game the sound files are really short and so they aren't usually long enough to drift out of sync.

Let me know if you have other concerns.

Regards.

Thank you for confirming your setup, mkerfers. Noting that it's both connected to the onboard graphics card, then it's possible that this is due to video card limitation. It would be best to further check for other possibilities.

Please confirm the make and model of your video card.

For us to isolate the issue, try to run the game on the main monitor, then stream or play a video on the second monitor. Once the audio and video starts to drift out of sync, drag the playing video from the second monitor to the main monitor. Observe if it
changes anything or if the sync issue stops.

Please report back the outcome as this is will help us identify and formulate a more established workaround for your issue.

Looking forward to your update.
