The video stream stutters.

Samsung QE55S90CAUX 144Hz 4K main
LG 1080 60Hz for chats and OBS
If I watch OBS on the LG, the stream stutters. If I move the OBS window to the Samsung, the picture is perfect on the stream, but I can't see what's going on in OBS.
Why is that?

Please post a log with your issue! Here's how...

OBS Studio creates a log file each time you run it which contains very useful diagnostic information. Without a log file, it's much harder for any support volunteers to figure out problems and your post may be ignored. To upload a log file, go to the Help menu > Log Files > Upload Last Log...

Rendering lag is GPU overload

1. Run the Samsung @ 120HZ
2. Disable HDR/10-bit color on the Samsung
3. Fix your Scenes, they're all bugged with multiple captures. There should only be (1) Display, Game or Window capture per Scene to avoid interference.
4. P5 is the correct Preset
5. qres or Single Pass/Disabled are the correct Multipass settings.

Lg max 60HZ+SDR
The preview window stutters, even without starting the stream. If the OBS window is on a Samsung, there's no stuttering.
When starting a stream on a CPU, there's also stuttering, regardless of the preset.
 
What about your crappy Scene Collection, did you fix it? All those captures could be causing stuttering too.

I recorded another video demonstrating the issue. In the first part of the video, the OBS window is on the game screen (Samsung). In the second part, I moved the OBS window to an LG, and stuttering immediately started.
