Dual Monitor Youtube frame dropping

[Farfenkugell]

Hello,

 

Looking for a possible solution to a long ongoing issue, which is just irritating. 

• Had a full-size desktop PC with Ryzen 3700x and Nvidia Rtx 3070
  • Dual monitors connected to GPU via HDMI
  • But if Chrome, now Thorium, is maximized on the second monitor it starts dropping frames like crazy and eventually freezes and starts appearing like buffering
  • Now the fun part, if those browsers are not maximized (you can drag them out to be a few mm from covering full monitor) it does not drop frames
    • If the same non-maximed browser is set to show YouTube on Full screen, no drop frames.
• Downsized to MinisForum UM780XTX (NUC pretty much), with ONEXGPU connected via oculink
  • One monitor is connected via DP, the other via HDMI, pretty much an identical situation
  • *weirdly enough if it is connected via DP and I turn on or off monitor, whole system freezes, but the same was happening with GPD G1, so maybe just eGPU and AMD thing or even oculink, not the point at this moment

 

So ryzen+nvidia issue.

Ryzen+amd issue.

 

Disabled HW acceleration on the browser, for like a half an hour thought it made things better, but nope.

 

Disabling the second monitor removes all issues.

Monitors are the same brand, but different models running at different resolutions and different refresh rates:

• LG UltraWide Curved Monitor 34WP65C-B 34
  • 160HZ 
  • 3440 x 1400
• LG 27UL650-W
  • 60HZ
  • 4K or FHD, does not make much difference.

 

Any suggestions? Any magical Chrome: Flag to adjust? Anything in Windows to disable?

I do plan to check other browsers or test this behavior in Linux live boot.

Any chance there is HDR enabled somewhere? I had some issues with that on LG monitors

Also, does YT's Stats For Nerds show dropped frames?

Off on both.

One of monitor has color palette (in monitor settings, not OS part) set to HDR can change it to something else.

Both monitors running on RGB 4:4:4

Non maximized:

 

Maximized, frames drop, stuttering, eventually buffer rans out:

Try running both monitors at 60Hz. It's a common issue with mismatched refresh rates.

Try running a different browser like mozilla firefox or brave or even re-try google chrome to test like you had suggested.

 

 

Thorium browser hasn't been out long enough which would incur problems.

WOW. That is wild. You're going from 42Mb/s to 8.4Mb/s
I assume this behavior is consistent across Chrome and Firefox in addition to Thorium.

This seems to fix it.

Just unsure what to do next

 

Get a second High Refresh Rate monitor, which serves no purpose.

Or keep my high refresh rate monitor at 60HZ

Correction, it made things a lot better, but still wonky sometimes, I just now can't track what causes it.

 

Now it sometimes starts dropping frames, but not to the point where the buffer runs out.

I've experienced the exact same, when using my 5120x1440@240Hz (primary display) and 3840x2160@165Hz(secondary display) monitors. The cause was Multi-Plane Overlay (MPO), a power saving feature that is enabled by default on a Windows level. If you wanna give it a try, you can disable it via a regedit:

Go to "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Dwm", create DWORD called "OverlayTestMode" and give it value "00000005" - restart your system. (Windows update can revert this DWORD change I've read but never seen Update revert it on my system).

Seems like this plus running both monitors at same refresh rate is almost perfect solution. 

Just this is acceptable and usable, to the point where it does not get in the way.

 

BIG THANK YOU

 

10/10 to Microsoft for making another feature which just causes more issues.
