Custom Resolution Utility (CRU)

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.

Does DisplayPort have the same 25mhz minimum pixelclock threshold as HDMI?

please help. on my laptop after purchase there was adaptive control of the screen refresh rate from 60-165hz
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?

This is so good! йhave one question though. When downscaling 3340x1440to 3440x1200 to make the screen area shorter, I have letterboxing top/bottom. Is there way to consolidate the blank area to bring active area to top of the scree?

Hello

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

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.

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

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