Add an extension block and change the type to DisplayID 1.3. Then add a detailed resolutions data block and add 3840x1600 @ 120 Hz in there.

Ok, done as you said, 3840x1600 120Hz, applied and restarted

In the "Detailed resolutions" tab, 3840x1600 60Hz continues to appear

Sorry, what else do I need to do?

That should be all you need to do. Is 3840x1600 @ 120 Hz still not available? Export another file so I can see. Does display scaling vs. GPU scaling in the NVIDIA control panel make any difference?

I just redo everything again, same result

Display scaling, GPU scaling, same thing, no success

Edit, just an update after making the DisplayID extension block

On the NVIDIA panel, the color depth setting was at 8 bits by default after these changes, so I set it to 10 bits again as it was, saved and the screen went black. Luckily it reversed itself

Something really isn't right

I feel like both drivers are broken. The new driver is broken because what you have should work. The old driver is broken because if 3840x1600 @ 120 Hz didn't exist in the EDID, then how is DSR working at 120 Hz? It would have to GPU scale the DSR resolution to 3840x1600 and then GPU scale that to 3840x2160, or it's lying about the refresh rate. You should check the info section in the TV's menu and see what resolution and refresh rate it's really receiving.

I agree

But everything is being displayed as it should. I've been using these settings since I set it to 21:9 ultrawide. It's always been like this, setting 60Hz on the CRU, it's always worked, with dozens of drivers up to the 556.12

Very strange, I think I'll have to stay on it for a while longer, or stop using DSR to update the drivers

Anyway, thanks for your patience and help

Hello everyone,
I need your help with the following case.
My RX 7900 xt permanently clocks the VRAM boost at 2487 MHz.
I've already played around with cru, but I don't understand everything yet, so I just wanted to ask here if anyone knows the optimal settings for my monitor configuration.

1. Monitor: 3840x2160 144hz (Gigabyte M32U)
2. Monitor: 3440x1440 100hz (HP M34D)
3. Monitor: 1920x1080 75hz (ACER QG271)

I've already played around with the Hz numbers and the resolutions, but unfortunately I haven't been able to find the optimal settings.
I've already increased the blanking time a little, but I wasn't sure how high I could go. If anyone has an idea how I can reduce my VRAM clock speed, I would be very grateful.
All three monitors are needed, ideally with the appropriate resolution, theoretically I would only need the maximum Hz number on monitor 1.

thanks

The blanking periods must be synchronized on all three monitors to be able to change the VRAM clock. There's no way to synchronize the monitors with three different resolutions and three different refresh rates unless all the monitors support some form of variable refresh rate (M34d doesn't). This would happen on NVIDIA as well.
