I upgraded from an AW2521H (G-sync module) to a 27GS93QE (basic freesync). On the old monitor, if I manually set a game/app to 'Fixed Refresh' in NVCP, it would behave nicely and simply not engage VRR when I tabbed into that game/app. On the new monitor, manually setting a program to 'Fixed Refresh' causes it to seemingly switch display mode every single time I alt-tab into or out of said program, causing a 2 second long black screen. This is true even of windowed programs like Photoshop (where disabling VRR is a must due to tons of stuttering and flickering that it causes).

Is there any way to fix this or is it an unavoidable downside of the G-sync module-less hellscape we now exist in?

I had something similar and the fix was to reset the global profile in the nvidia control panel (with the "Restore" button.)

The problem would reappear sometimes if I kept using NVCP to set some games to fixed refresh. If I instead use nvidia profile inspector, it doesn't happen:

If you don't have profile inspector, it's this:

Thanks. Resetting global profile in NVCP did not work but using NPI to disable Gsync instead of NVCP did work!

Maybe you have to reset all customized profiles in NVCP, not sure. The problem also caused another issue for me, where after booting into Windows, after 5 seconds or so, the screen would blank out for half a second then come back. It did this exactly one time, every time after rebooting.

Just weird.

I also get this exact issue... I'm starting to wonder if it's time for a clean Windows reinstall. These little issues aren't getting fixed even with a clean driver install.

DDU fixed it for me before I discovered it can be fixed by NVCP reset. However, I think the reset working might depend on whether g-sync support in enabled or disabled in the G-SYNC section of NVCP.

I'm still not sure, I'm getting this error.

Right, a new monitor shouldn't introduce such headaches. Variable refresh rate woes, a modern curse indeed. I remember a similar situation, though slightly different, when dealing with resolution scaling on an older TV. Disabling specific features created unintended chaos with the signal. This sounds like a driver issue, potentially related to FreeSync implementation. I once had the most unusual experience trying to present a PowerPoint on an ancient projector, and every slight Adju Slope stment to the brightness caused the whole screen to flicker uncontrollably, forcing me to present without visuals.
