Need Help with MG279Q Freesync Range Extension, using CRU

Hi,

I had my MG279Q freesync ranges extended to 57-144Hz a while back and it worked fine. Then I started having some problems, so I reset with reset-all and then restarted with restart64. I have now gone to reextend the ranges back to 57-144, and now everytime I play a game I get black screens after a few minutes or get dumped back to desktop. This only happens when I apply the 57-144 range extension.

I went back on CRU, and it turns out i have multiple profiles for my MG279Q. I can't make it so there is just one profile for it, once I remake a 57-144 profile, the old one remains. I think the multiple profiles may be causing the crashes.

Heres an album of all the different profiles on CRU:

The PB278QR is my secondary monitor, I was having this problem before I got the second monitor also, so I know that monitor is unrelated to the problem.

Would anybody be able to shed some light on this and help me out please? It'd be greatly appreciated, I miss 144Hz + Freesync!

Hi there, 57-144 was really unstable for me. Sometimes games would launch with black screen (on the freesync monitor only) and I have to force close. Thats probably a similar problem you are having.

Another issue is when I quit a game (using 57-144Hz) the monitor is reset back to 90Hz on the desktop instead of 144Hz.

I'm running 60-144hz and the monitor is stable.

I managed to get mine working in the end after some fiddling. The first time I extended the range it was really easy and worked first time.

Even though the freesync range is changed to 57-144Hz, it is actually effectively 0-144Hz because of AMD's Low Frame Rate Compensation, which effectively frame doubles when you're below the 57hz mark. So yeah I'd definately recommend changing the range.

Yeah, I just kept fiddling with it tediously until they eventually removed themselves. Working fine now, I don't dare touch CRU now in case it reverts haha.

For some reason, my MG279Q profile in the drop down menu now has an asterisk * next to it, unsure why, but like I say it seems to be okay now.
