Custom Resolution Utility (CRU)

[laxu]

Does anyone know why my Samsung G70A seems to have completely separate EDIDs depending on if I'm using 144 Hz w/ VRR vs 120/60 Hz w/o VRR? Any reason why Samsung would separate them like this?

The 144 Hz EDID seems much more barebones than the 120 Hz one. It also seems to cause Nvidia's "do scaling on the GPU" to limit it to only 144 Hz refresh rate if VRR is enabled.

That seems to be the standard on any Samsung monitor. Mine is a lower-end model, a U32J590, but it also has different EDIDs depending on the chosen input and whether I choose to enable FreeSync or fixed refresh rate.

Using FreeSync, I can supply multiples of 60 Hz (like 120, 180, and 240 Hz, depending on the resolution) to the inputs which the monitor then uses to smoothen out some animations a little bit despite still showing only 60 frames per second.

OK, 761 pages of comments for this thread. You'll forgive me for not reading all of them.

I have multiple Windows 10 machines connected to a monitor via a KVM. When I switch connected machines, the Windows on the machine I'm switching away from are shrunk and repositioned. Does this CRU utility provide a workaround for this so that I can switch machines without triggering repositioning of the Windows?

My graphics card is a GTX 4060, so I don't have the Quadro feature of saving/loading EDID from a file like the Quadro drivers.

Hey.. first off great bit of software toastyx definitely worth a donation

SIM racer hear running Nvidia surround triple screen 2 LG monitors 165hz and 1 MSI 144hz all 2560x1440
GPU is 4090 all monitors connected by display port

I was having the problem of only being able to select 60hz when using Nvidia surround and searching for a fix I ended up hear.

What works for me is copying the MSI timings and paste to both of the LG monitors restart the monitors then I can when I enable surround I get 144hz. All good

Problem is when I restart the computer it does not save and I am back to 60hz and have to do it all again.
Is it possible to save so when I restart my computer I don't have to do it all again.. thankyou

Im using amd 23.8.1 gpu driver and trying to add 1280x720@75hz, but after restarting the driver i get 1280x720@75hz and 1280x720@60hz. How can i delete 1280x720@60hz resolution? Im using HDMI output, already deleted everything in SRE.

Hello all!

So I'm at a dead end and pretty sad tbh.

I have a t570 and it has a BOE panel, 1080p60.

It is powered by an 6th Gen i5, Intel HD 520 and a 940MX in an Optimus configuration.

I have tried all Intel HD Graphics drivers, tried the EDID override, patched the Nvidia driver, added refresh rates below 100Hz.

Despite all this nothing has worked.

I'm just trying to add a refresh rate above 60Hz for the internal screen on the laptop.

I am thinking by this point there's nothing else to try, and so may be just trying to buy a 144Hz screen instead.

I had no issues on my older laptop running a 4th Gen i5 and HD + Nvidia setup...


If anyone can help I would be over the moon, I hope there's a possibility!

Intel's driver does not allow EDID overrides with some laptop screens for some reason. Intel controls the resolutions in an Optimus setup, so you'll have to ask them why they're not allowing EDID overrides.

AMD forces certain TV resolutions to exist with HDMI, but you should be able to hide them in the Windows display settings > Advanced display settings > Display adapter properties > Monitor tab > enable "Hide modes that this monitor cannot display"

It does save, but NVIDIA's driver has a bug with Surround that can cause it to reset after rebooting when using EDID overrides. You should report that issue to NVIDIA support.

No, CRU does not emulate monitors. You would need an EDID emulator to keep a connection, or you can use software such as winredock or PersistentWindows to save and restore window positions.
