Custom Resolution Utility.

hmm.. it should be there.. but You can enable a custom resolution pretty easy. That's what I do with my old 60hz monitors ! (my tv can do 137hz).. for basic, nvidia/customize then enable a custom resolution.. or " Custom Resolution Utility aka CRU and just program a few. very simple

May I know what are the possible solutions to this without replacing the 5D10R41286 LCD Display, as well as the maximum range of the monitors refresh rate at 1920x1080 using CRU. https://www.monitortests.com/forum/Thread-Custom-Resolution-Utility-CRU

I've recently went down this rabbit hole myself as well and found Custom Resolution Utility (CRU) [1] to be an efficient EDID editor.

What I've Tried So Far: I've tried to download CRU (https://www.monitortests.com/forum/Thread-Custom-Resolution-Utility-CRU) and I have tinkered a bit with one of the monitor parameters. I have faced some black screens and I have reverted all the changes. I have seek help online, but none of the solutions seems to work for me. Both monitors are connected using DisplayPort, and they work fine individually with their native resolutions and refresh rates.

To overcome this limitation, I downloaded the CRU tool and created a custom resolution of 1440p @ 59.9Hz, and everything started working perfectly! At 1440p, the studio display looked just right in terms of scaling, and it was sharp enough for everyday use. I also tested some gaming, and the 3070 performance was more than sufficient; 1440p at ultra settings consistently stayed at 60Hz!

I downloaded custom resolution utility here https://www.monitortests.com/forum/Thread-Custom-Resolution-Utility-CRU , theres also another website https://custom-resolution-utility.en.lo4d.com/windows IDK which one is legit, is custom resolution malware? or is it safe? for all of you saying just use the Nvidia or AMD settings im on a laptop and my Nvidia control panel doesnt have Resolution tab

I had the exact same issue. Just use this Custom Resolution Utility - https://www.monitortests.com/forum/Thread-Custom-Resolution-Utility-CRU - You will want to create a custom resolution that is 2880x1660. You can use this to figure out how to use the software (scroll down to A Little Outside Assistance...) - https://www.alphr.com/set-custom-resolution-windows-10/

OP's approach looks cool but a bit baroque. I'm also hacking around EDID issues and it turns out there's a nice GUI program to decode and (lightly) patch it: https://packages.debian.org/unstable/utils/wxedid

I have to do more involved full EDID reconstruction surgery tho since I need to add DTD entries rather than just change existing ones. So I'm looking at [edid-generator] together with [cvt12]. The latter can calculate xrandr modelines for VESA standard timings that all seem to work with my TV. It adds an option for NTSC timing over regular cvt which is already in Debian.

4) On Xorg, a custom resolution is represented using a "Modeline", which can be manually calculated, or generated using a utility like cvt. There's also a modified version with more advanced options. Then the modeline can be temporarily added using xrandr, or permanently added using /etc/X11/xorg.conf. Though in my experience, the Nvidia driver is a bit picky about adding modelines sometimes, it seems to be more accepting if you add them in xorg.conf instead of xrandr, and also if you add settings documented here to xorg.conf to disable some forms of mode validation.

Instead of using cvt or gtf, I used cvt12 to get get my Modeline. With cvt12, I was able to get a refresh rate of 160. It is 10 frames lower than my monitor's max, but I'm still happy with this solution.

If you haven't jumped ship to Wayland yet, maybe try using the same custom modeline for both screens? IIRC, you generate the modeline with a cvt calculator that supports reduced blanking v2, and then use it with xrandr --newmode , xrandr --addmode , xrandr --output --mode . Those 3 commands will need to be autorun on login, or possibly you could put the modeline in an xorg.conf.d snippet.

As to how I got the "magic" numbers in the first command? It was done via this program: https://github.com/kevinlekiller/cvt_modeline_calculator_12. I ran it like this:

Then you use the cvt tool (https://github.com/kevinlekiller/cvt_modeline_calculator_12) to calculate a new modeline for your monitor (I'm assuming by "custom" refresh rate, you want to overclock your monitor)
