I can't find any information on DisplayPort's minimum pixel clock. I know HDMI and DVI require at least 25 MHz. Strangely I just tested DisplayPort and HDMI with a GTX 1070 and the driver allows less than 25 MHz for both. I don't know about AMD, but I remember there being a 25 MHz limit.

oh btw, i forgot to ask, does this mean nvidia lets you create 256x240 120hz resolution on CVT Timings using HDMI on your 1070??? even if it doesnt appear on the nvidia panel or windows node list, retroarch will let you switch to it if its truly compatible.

It does, and I can select it using HotKey Resolution Changer, but I have no way of knowing if it's actually sending a signal because my monitor won't display it.

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

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

Hello

In the last few weeks I contacted NVIDIA. According to them, the problem is with the driver itself and has been fixed in the latest versions

Well, I tested the last driver and again it is not working at the resolution of 3840x1600 at 120 Hz to be the native resolution, in order to use DLDSR

If I don't use CRU and leave 3840x1600 as not the native resolution, not being able to correctly scale DLDSR, well, it works at 120 Hz normally

Funny that the last driver to work perfectly is 556.12. I explained this to NVIDIA support but they don't seem to understand it well

Now, am I going to continue with 556.12 forever? I tried everything without success

Does anyone have any ideas?
