HDMI allows me to alt-tab from fullscreen games seamlessly as if they are in window-borderless mode. Whereas DP causes a second or two delay like its shifting refresh rates (although its not). Just my 2 cents. Also don’t know why that would be the case.
Wow what a difference!
Just updated to V032 and switched to the HDMI 2.1 cable on an RTX 4090 FE and alt tab in fullscreen mode is instant. Was always a few second delay like you said with DP.
Thanks for the tip
