Can someone share default XL2540 (.bin) file from CRU?

What timings preset should i use if im using a gaming laptop? Im trying to reduce my 144hz screen into 120hz

Normally 144 Hz screens already include 120 Hz. If not, the screen might not support 120 Hz with standard timing parameters. Normally "Automatic PC" is sufficient, which uses CVT-RB for most resolutions. If that doesn't display correctly, you might have to use the vertical total calculator to keep the pixel clock the same as 144 Hz: https://www.monitortests.com/blog/vertic...alculator/

Frame skipping is not an issue with timing parameters. Frame skipping in the monitor is caused by the scaler doing frame rate conversion for unsupported refresh rates.

Be careful. My gaming laptop's 144 Hz screen only accepts its default timings fo a smooth 144 Hz and will otherwise default to 60 Hz.

Setting it to, e.g., 144 Hz with your own timings or to any refresh rate between 60 and 144 Hz, like 120 Hz, will actually let it display 60 Hz.

Anyone support or anyone tried to overclock oled screens on laptops? More specifically a ryzen laptop with a 60hz oled panel and igpu. What about a 1080p oled panel like this laptop: M1505YA-DS52 would it have a chance or is OLED no-go for changing the hz at all?

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
