Custom Resolution Utility (CRU)

CRU only deals with active signal resolutions, but lower resolutions can be scaled to the first detailed resolution if you enable GPU scaling in Intel's control panel. The problem is Windows doesn't provide a way to set the resolution below 640x480, so assuming the driver allows 384x128, you'll need a third-party program to actually set that resolution. I don't know how you did it before because that was always the case.

Interesting.

on that note, i noticed in CRU that my monitor has the default CTA-861 extension block, but when i click the arrow to see what else it contains, i see a listing of "VTB-EXT" extension block, which contains a duplicate of the resolutions contained in CTA-861 block, minus the colorimetry and hdmi and other stuff in cta.

Ive done some searching to see the difference between both extension blocks and it seems like VTB-EXT is the way to go for displayport. and yes, i know CTA 861 is supported by displayport too but i honestly feel like the image/video is much smoother and doesnt have as much flickering/artifacting/color issues as when i have it set to CTA-861, both identical extension blocks with the same settings.

do you have any input on why this is? ive read the documents on both cta-861 and vtb-ext, they both seem to have the same goal in mind, to provide info to the GPU. can i use VTB-EXT as a replacement and what is the difference between both? why does the image look smoother?

edit: i use displayport to connect my display. Acer xb253q GP and it supports DP 1.2/1.4 (g-sync compatible) and HDMI

You're hallucinating.

After I manually choose 170 Hz on the 60 Hz monitor the other one defaults itself to 165 Hz. If I restart the PC the monitor with 170 Hz keeps its refresh rate, while the other defaults back to 60 Hz. In CRU i am not able to add the 2560x1440 @ 170hz res. Whenever I type in the refresh rate 170, it becomes red and it doesn't let me save it. I tried to copy the settings from DisplayID 1.3: 1 data block (that one has 2560x1440 @170 Hz), but it wont let me save it like this either. One monitor is connected via DP to DP and another one via DP to USB-C to my PC. Graphic card is a crappy Intel Arc (i5 13th Gen). Disabling or enabeling Freesync in the monitors OSD doesn't help either. Anyone can share some light in this issue? This will be greatly appreciated.

Your GPU can't run both at 170 Hz. There's no point in adding a refresh rate that's already there.

So I am in a bit of a unique situation as I don't think this is a very common setup and I have not been able to find a solution for the problem I have been having. For some reason in the Nvidia control panel the "customize resolution button" is greyed out so I cannot try to add new resolutions. With the program CRU when I tried adding resolutions they do not appear in Nvidia control panel. Even upon inspecting with regedit in ->Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\​Configuration editing the values here had no affect. Can someone please advise me on possible remedies for this? My main goal is to create a custom resolution of 7680x2610 so it would be selectable in various games, with this resolution I can have an ultrawide display with games running on it and two small windows at the top for productivity while gaming.

NVIDIA has limitations with DSC. Try SRE: https://www.monitortests.com/forum/Threa...Editor-SRE

hi there, I have 7900xtx and I can't set the lower range of freesync via CRU, I saw several messages in early 2023 that the driver for rdna3 ignores the EDID settings, is there still no way to fix it? even custom drivers like r.id don't they help?

If im adding ultra wide resolutions for a LG CX - what timings should i use? It is an OLED afterall, and there are way too many options.

Heyo toasty, have a bit of a edge case issue here that I was hoping CRU might be able to help me resolve. I currently have two displays hooked up, a 27" oled monitor and a 48" LG C1 oled tv. The issue im having is that even with my monitor set as my primary display when I turn on my pc with my television turned off I get zero video output until I turn on my television. Doing some finicking with every setting possible and it seems to be an issue with the different resolution categories listed in nvidia control panel. When running a resolution from the "Ultra HD, HD, SD" Category the issue goes away, however when running a resolution from the "PC" or "Custom" Category the issue returns. The thing that sucks here is that the Ultra HD category lacks a 4K@120hz option. Meaning that I have to run 4K@60hz to avoid having to turn on my TV every time I want to use my PC. Is there any way to add a 120hz option into the Ultra HD category? If not that, do you have any suggestions on how to fix what clearly is a bug on nvidias/lg's side. I even tried hooking up a completely different PC and the issue occurs on there also which rules out my system being to blame.

perhaps. but they are both extension blocks, they both contain the same resolutions, they both do the same thing, moninfo changes extension block listing from (CEA/CTA-861) to (VTB-EXT), so a change is 100% done. i just wanted to know if there is any difference in how the resolutions within each extension block is sent. or do they just have the same exact function minus the VTB allowing colorimetry, audio, and other stuff?

well I found solution for my problems with freesync range on rdna3
just change value of freesync in "extension block > cta > freesync". Not just in active monitor > edit

DisplayPort or HDMI?
