Increasing Freesync range advice.

Hello, i overclocked my monitor asus vs278 from 60 to 75 hz. Than i applied freesync range 33-75.
My games in fullscreen mode keep running while in blackscreen, it doesn't happen in borderless window mode or window mode.
Deactivating free-sync will fix the black screen in fullscreen mode.
Do i have to change the range to fix blackscreen in fullscreen mode? My monitor doesn't support freesync natively, but would like to know how to find the correct range for non freesync monitors if possible.
I already checked the depth of color and is greyed out, so cannot be put to 6 to fix the issue.
I'm on hdmi, latest amd drivers, r9 390 nitro is the gpu, windows 10.
If need further info ,just ask.

Hey man, i know its years later, but i cant get my freesync range to improve from 48-74 hz...
My changes in CRU won't be applied to my radeon settings, if i restart or not, it doesnt matter

I don't get it.
I have 279Q aswell. Downloaded CRU, checked everything regarding manual and modified range to 143Hz. But monitor still keeps saying Freesync is disabled when I change frequency from 90Hz to 144 in control panel.
What am I doing wrong?

You will see message on screen that FreeSync is disabled, but if AMD driver panel shows it as enabled (hover over switch and you should see range) then all is well.

You can check FreeSynce is working by running a game and seeing Hz change in OSD.

I have attached a profile for ASUS MG279Q for use with ToastyX's CRU, it will apply 57-144Hz FreeSync range. Just load profile, apply and reboot.

I have 1080 Ti, so testing it through nv control panel - it says, "g-sync is active".
You think it really works? I mean, I can't see any changes, because I simply have no tearing in games
OSD shows refresh rate floating with 144Hz set in control panel - the actual value is 143Hz, varying time to time.
Though, I must say, Freesync worked within 144Hz even on day-1 when nvidia released those drivers - I saw rate floating around 143Hz mark, as well as Freesync was ON in OSD menu - it's just about that message popping out about 35-90Hz range.

Maybe it's something about nvidia drivers and gsync range. Or maybe I had the monitor modified a long ago - however, the last radeon I've had was 7950, and it didn't supported freesync at all.

P.S. I've changed only upper range from 90 to 144Hz - so it looks like 35-144Hz now. Does it have to be more conservative, like you've done, from 57 to 144? Freesync range limiters?

YEAH! That worked - I've changed the range from 35-144 to 57-144 as you've mentioned in your tutorials. And I've got rid of most of artifacting and flickering. I'll test more in order to check everything's set up.

So, I'm curious, why low frequency - or is it range too extended? - makes the monitor artifacting? I didn't thought adaptive frequency sync that hardware related..

With Nvidia go to NVCP, select one of the Gsync menus, go to main menu, something like "Display" - "show Gsync compatible logo", it will then show an overlay in DX11 and OGL applications (maybe even DX12 and Vulkan, didn't test those, don't have any) when Gsync compatible output of NV GPU is active. That still doesn't mean your monitor is also in Adaptive Sync mode and synced up correctly. But at least lets you see what the GPU is actually freaking doing as there are games that run Windowed mode only and will not run adaptive synced, instead they have forced Vsync from Windows and you're always getting lag with that.
