Custom Resolution Utility (CRU)

[Svyatoslav]

Hello guys!

Got a problem. Using this monitor Samsung U32H850 4K 60Hz FreeSync ON with GTX 2080 Ti. If I put in CRU range limits something more than 30Hz to 61Hz "G-Sync Pendulum" see my G-Sync setup but doesn't work, doesn't show smooth picture. It works only if I put 29Hz to 61Hz. Don't know why so. My monitor is 60Hz and via DisplayPort it doesn't show anything except 60Hz under nVidia Control Panel and FreeSync supposed to work on 60Hz. I would not ask as I hadn't one problem with this setup. If I play the game, in the game itself, I mean, while I am playing everything works fine and smooth but when the game showes me some cut scenes or movies or sometimes in the menu I see some rubbish which divides my screen by two same squares. Pictures are attached. How to get rid of this? Who knows why so?

Thank you beforehand!

The maximum range is limited by the current refresh rate. 61 Hz does no good if the refresh rate is 59.996 Hz. If you put 30-61 Hz, that leaves a hole between 29.998-30 Hz that LFC can't cover. Are you sure the TV can handle an extended range?

Hi guys,

I've been working on getting my QNIX 2710 without scaler connected to my new graphics card (RX 5700XT), but so far only managed a 40Hz connection via Club3d HDMI to Dvi-D cable:
https://www.cyberport.de/pc-und-zubehoer...-1210.html
On my previous RX 480, I got 110Hz. The cable claims to be able to transmit UHD / 3840 x 2160 @ 30Hz.
So I guess the problem is the graphics driver still having the HDMI-DVI limit in place, even though I used the patcher for this. Any ideas of what I could try?
I have included a screenshot of all my settings and driver info.

Thanks for all the great work!

HDMI-DVI cables are always single-link. You won't be able to get 110 Hz with single-link DVI, but 60 Hz should be doable. Don't add HDMI support if you're using the patcher.

Okay, thanks for the info. I'm goint to try this one:

Some spanish guy in the amazon reviews says he got 110Hz on that monitor running, so I'm hoping for the best.

I don't have this particular adapter, but my experience with a similar Accell adapter is AMD limits this type of adapter to 300 MHz pixel clock with 8 bpc color and 400 MHz with 6 bpc. That's enough to get 100 Hz with 6 bpc, and AMD dithers 6 bpc well enough. With NVIDIA, the adapter is capable of 357 MHz at 8 bpc and 476 MHz at 6 bpc.

For some reasons it does the same result at 59Hz, at 60Hz, even at 64Hz and 70Hz. I agree that 29Hz is out of 30-61Hz range, thats why i set up 29-61Hz. Some people say if you setup just 60 then freesync doesnt use value of 60, the higer value it use in such setup is 59, that's why you should put 61. Don't kbow if it's true or not, as i mentioned above, my monitor goes with both refresh rates at the same result.

By the way, i got rid of artifacts in games by setting up limits to 19-61 Hz. Don't know how it works and how it helped.. But Pendulum if i simulate 40-60 works smooth, if i simulate 50fps - works smooth as well, but if i simulate 60fps - sometomes i see tearing. So freesync doesn't work 100%.

Who knowes how to set it up in details?

If you put 29-61 Hz but the detailed resolution is 59.996 Hz, then the range is 29-59.996 Hz. You need to change the detailed resolution to match.

Hi, Just wanted to let everyone know that I got 110 Hz with the linked adapter (club3d cac-1010) on a RX 5700xt paired with a QNIX 2710 without scaler.
Hopefully this will be helpful for someone.
I'm anyway happy to be able to use my monitor for a few more years. Thanks!

Greetings,

I have the AOC 24G2U 144Hz monitor and an AMD gpu (RX 5700), so when I set the refresh rate to 144Hz the memory no longer down clock (it's fine for 120Hz though). Using DisplayPort cable that came with the monitor.

I tried all 3 settings for LCD monitors, but only the 'Automatic - LCD standard' seems to let the gpu memory down clock. The problem is that as soon as I start a 3D game the monitor goes black and says 'Input No Support'. I have to blindly alt+F4 out of the game and select the DisplayPort as input again in order to gain back picture.

Is there anything I can do to make 144Hz work?
