To do this , we'll all my resolutions were the 3440x1440 ones , so I simply changed them all to 2560x1440 and didn't touch anything else.

It appeared to work, however when selecting any hz besides 60 or 120 I get a black screen. My options are 60 100 120 144 175

For reference, I can use other hz such as my native 175 on 2560x1440 when choosing it in the nvcp when I don't make changes by removing the 3440x1440 ones with cru, or rather changing them to 2560x1440 ones would be more exact.

So something about 2560x1440 now being my native resolution caused this maybe?

I tried going back into cru and tried different timings such as exact reduced, yet sadly to no avail.

I'm extremely fresh to this all so excuse my ignorance. Could I please get some assistance? It would be very appreciated

For reference I'm trying to use a 175hz, which is my monitors native max. And considering g sync exists , I haven't the need to play at anything lesser. So as long as I can get that working that's plenty for me!

Aw3423dw. Newest GeForce driver, let me know if there's any other information I should provide.

Thanks in advance!

Monitors with NVIDIA's G-SYNC hardware only support a limited combination of resolutions and refresh rates. The AW3423DW only seems to support 60 Hz and 120 Hz at 2560x1440. The graphics driver automatically adds some common resolutions as scaled resolutions. If 2560x1440 didn't exist in CRU by default, then it was being scaled to 3440x1440 by the GPU.

I'm so confused as I'm currently using 2560x1440 at 175hz. And I've been using it. I also just set the native resolution to 2560x1440 in cru *withOUT* deleting the other 3440x1440 resolutions/changing them to 2560x1440.

And it works , I can use 2560x1440 at 175 hz. It's selected and applied right now currently with this cru setup, and when not using cru I obviously could select it too , but even when using it to change my native resolution I can choose 175hz.

However only when I remove the 3440x1440 resolutions or change them. Then I can't use said refresh rate.

Am I missing something? Why am I always able to use 2560x1440 at every single hz the monitor comes with UNTIL I do the specific cru action of getting rid of the 3440x1440 resolutions that are attached to said refresh rates?

Thank you for taking the time to respond

Also unfortunately having my native resolution at 2560 isn't enough, I guess nvidia chooses the silly route of basing dldsr off your max resolution not your native.

Would you know any way I could use your program to get around this?
