I would like to ask for help to identify the cause of the problem. I bought the ARC A770 board precisely to bring a better experience to my followers (my page has 700 thousand followers), but unfortunately I have brought more problems than benefits. Believe me, the problem no longer occurred. I removed the card and replaced it with the previous card, which was a Geforce GTX 1060 and configured the Nvidia NVENC (new) in streamlabs. I've tried to format my PC Stream and nothing, neither with windows 10 nor with windows 11. When I use StreamLabs with 1080x1080 configuration and QuickSync H.264 to perform my lives, there is a problem from time to time, where my transmitted screen is divided in half (not always with the exact aspect ratio). My PC Stream has XEON E5-2699-V3 + Huananzhi F8 and Intel ARC A770 processor configuration. I'm a streamer, my main PC has a Ryzen 9 5950x processor and a Geforce RTX 4090 graphics card. Gamma – Essentially a more subtle form of brightness and contrast control, Gamma correction adjusts the amount of dynamic range between light and dark.(I'm Brazilian, I speak Portuguese and I used Google Translate).Brightness – This affects the overall brightness of your source.Contrast – This affects the overall difference between light and dark in your source.Opacity – Move this slider to the right to make yourself more transparent.Key color spill reduction – Sometimes, your lighting will cause some green tones to reflect onto your skin or clothes.

This can be useful if you have frizzy hair or clothing with a texture that makes your outline appear fuzzy.

Smoothness – Use this to soften the edges of the green area and create a smoother transition between you and the background.

If your screen is unevenly lit and only the “greenest” parts of it are being detected, move this slider to the right until all the green is gone.

Similarity – This setting controls the range of hues that Streamlabs will key out. This short tutorial will run through how you can add your friends' webcams to your livestream so you can stream all together from one single stream.UPDATE.
