It's not a dead pixel either and also my old monitor didnt do this. I had this monitor brand new 2 days ago it usually wont do these red pixels back then. Its also not the gpu im certain. I didnt experience any symptom of artifacting ever. So what would be causing this? Oh and when i up and down the red pixels would be temporarily gone but the moment i hover my cursor on the video it would come back. The fix is also that i need to watch a 4K video and the red pixels are gone for now until i restart chrome again.

When im gaming i dont usually encounter these issues. No pixels etc. only when it comes to "Some" Youtube videos. some arent affected and some are. The red pixels usually are at a black surface. When i pause the video the red pixels are there but when i hover my cursor to them. The pixels wont stay on the monitor it's like the video is the problem? This only ever happens to some videos on YouTube usually on dark spots or like small tiny spots you can catch onto. It only ever applies to some youtube videos, mostly not. mostly yes. If i try to take a screenshot using windows the pixels go away.

Monitor - AOC 24G2SE VA
Recieved this monitor with no damage on the box.
Did a dead pixel test and nothing came out of it no dead pixels.
Even resetted the settings and to no avail. Still have a 3 year warranty so yeah.
Still havent tried a clean driver uninstall so yeah could be that and this is the first time im using DisplayPort. as to back then HDMI. It also seems like if i try to zoom in on the video using Chrome's Zoom it would zoom it and make it go away for abit until i play the video and some spots still have red pixels if i set the zoom back to 100% but the pixels would go away the moment i watch lets say a 4k video literally 0. I really hope too that its not the gpu though i still have a 2 month warranty from it.

I have no clue whats causing this im also gonna send in a video for demonstration (*using this yt video in particular*) :

This response was short lived lol the pixels were there but it was only afew
But the issue is only prominent when watching a youtube video with hardware acceleration i dont think this was on the old monitor so yeah. I HOPE ITS NOT THE GPU.
 
Are you overclocking at all?

Can you try this with other browsers, and see what happens?
So here are my analysis:
Uninstalled/Reinstalled the Drivers - didnt work
Reverted the Driver to a old version - didnt work
Tried Different Browsers and watched the same video - the red pixels are there but only if with Hardware Acceleration
tried different monitors - not tried it yet.
Tried different DisplayPort slots - didnt work either.

The odd part is that i tried watching the video with Hardware Acceleration and with Microsoft Basic Display Adapter right. And the red pixels werent present.

So either this could be my GPU or my Monitor or my Monitor Cable.

Only Fixes are:
Watching a 4K Video and that would make it cease and restarting chrome would make it pop up again.
Turning off Hardware Acceleration - Permanently Fixes It unless you turn it back on
Watching it fullscreen - also fixes it but if you dont go to full screen mode the issues will start coming back.

Windows 10. and its only on certain youtube videos and youtube videos only. outside of yotube videos it does not occur.
I took a screenshot with the pixels using print screen and sent it to imgur and the pixels werent there so could this be my screen?
 
Found your problem.

It's a codec issue. Here's a link to a potential fix for the problem.

Don't need a new graphics card...yet!
Also i found another breakthrough. So it seems it only causes Chromium Based Applications. Like Google, Opera GX and etc.
Firefox isnt a chromium based application and when i ran it several times no red pixels were seen. I can confirm that this is probably on chrome's end? Without using AV1 Codec btw

sorry for the background audio
But it seems to affect Google Chrome, Opera GX havent tried Edge. But Firefox isnt affected which could only mean that this issue only exists in chromium applications. I used Firefox with hardware accel so yeah it still didnt persist thank god its not my monitor nor my gpu.

even with the AV1 Decoder it's still there but im gonna address this issue to youtube/google.
 
Though this may have been caused due to Chrome's end cause Firefox is working well.
Reported the bug/issue to google chrome themselves and either way im reinstalling windows in the near future. When my new ssd arrives cause this one is getting near to its death bed.
