Switching to Alt mode causes a black display when using two 4K monitors together.
Hi, your setup involves a 2080 Ti connected to two ASUS TUF VG28UQL1A monitors via DisplayPort 1.4 cables. You experience black screens after switching tabs in full-screen games lasting up to about 8 seconds. Sometimes powering on the monitors forces you to remove and reinsert the DP. Both displays run at 144Hz and 4K. Your suspicion about a NVidia driver bug related to DSC seems plausible. There are ways to address this—checking for firmware updates, resetting drivers, or testing with different cables/ports might help. Let me know if you'd like more details. Thank you!
Let me know what you're referring to with "the bios and the other drivers," and I'll provide a clear explanation.
If you're using Ryzen, upgrading to the latest version is highly recommended. Ryzen releases more BIOS updates than Intel does, and Intel also provides them. It's hard to predict which will be better. Are you running version 10 or 11?
Windows 10 runs on a compatible CPU, but this version isn't for Windows 11. The recommended build is https://au.pcpartpicker.com/list/2yg6w6
