regarding this DSC topic, are there any downsides aside not being able to use DSR/DLDSR on some monitors? Also what do you mean by two internal heads?

No custom refresh rates either. Each port on the GPU uses a head, but to support higher resolutions and refresh rates, it might need to "borrow" another head. This also means you can't connect as many monitors.

Since I don't have displayport at the moment, and as you know the aw2725df doesn't have a dsc toggle, I'm curious. If we create a custom refresh rate and load it through displayport while on hdmi would that force dsc off on the monitor as long as it isn't over the dp 1.4 bandwidth. This is because the aw2725df forces dsc on dp no matter what even at 60hz from what I heard. I'm not sure, but maybe it's a monitor EDID thing?

I don't see how that would make a difference. The issue is the driver ignores EDID overrides, so it will not take effect no matter how you do it.

I've been using CRU since I bought an OLED C2 in early 2023. The software is exceptional, it helped me set the 3840x1600 ultrawide resolution as native in the NVIDIA control panel

About that, since the latest 556.12 driver, the 3840x1600 ultrawide resolution is locked at 60Hz only

There is nothing wrong with the CRU, just the NVIDIA drivers are problematic, as always

Several other users are reporting to NVIDIA, including me, waiting for a solution

Does display scaling vs. GPU scaling in the NVIDIA control panel make any difference? What about if you add both 3840x1600 @ 60 Hz and 120 Hz? What about if you also add 3840x1600 with SRE: https://www.monitortests.com/forum/Threa...Editor-SRE

No.

then after the update it disappeared, I manually added the modes I needed with the help of cru and turn on 60 to save battery, but maybe with the help of this program I can make this mode again in which the laptop itself will choose the desired frequency, from the network 165 and from the battery 60 adaptively?

That isn't what CRU is for. You should contact your laptop manufacturer's support about that.

I can't find any information on DisplayPort's minimum pixel clock. I know HDMI and DVI require at least 25 MHz. Strangely I just tested DisplayPort and HDMI with a GTX 1070 and the driver allows less than 25 MHz for both. I don't know about AMD, but I remember there being a 25 MHz limit.

You need to reboot or run restart.exe to redetect the displays.

Hi thank you for this amazing tool. I used this in the past for many different monitors and TVs to create custom resolutions, or to change VRR window.

Right now I'm playing with AW3423DWF. I love the screen, but flickering in VRR is absolutely terrible in some problematic games like Alan Wake 2 for example, or Tekken 8 in loading screens, and character select screen, when 3d models load in and game stutters.
I tried to change VRR range from default 48-165 to 80-165 or even 90-165 and it flickers less but still not ideal.
The only way to have some kind of VRR without flicker is to use 60Hz. I actually created custom 63Hz using QFT so pixel clock is the same as default 165Hz to hopefully reduce input lag and leave some room for vsync. I Mostly play fighting games and graphically demanding single player games, using gamepad, locking everything to 60fps.
I'm using Nvidia GPU connected to display port and my issue is that VRR kicks in @50fps, it's a little bit high for my liking. I would like to lower it, but even 47-165 allready screen goes black.
Is there any setting in CRU that could let me lower it?
My previous 4k 60Hz LCD monitor had really nice 40-60 range.

You need to reduce the vertical blanking/total if you want to try a lower range. Using QFT would be like trying to change the range at 165 Hz, so there's no headroom. Other than that, you'll be limited by whatever the monitor will accept.

Now it says that my type of monitor is generic PnP monitor and not Acer

I don't think you should be using this program if you don't understand what you're doing.
