So i tried to use CRU, add 4k@165hz through extension blocks+ displayid 1.3/2.0. I can add 165hz4k via CRU but no matter what i do i dont see those options at nvcp and windows display settings. I did use all the restarting software it came along.
When i reopen CRU i can see my custom refresh rate resolutions at the extension block.

What to do? Thanks for the help.

Also idk if its important, when i first open CRU it shows 2 default extension block.

The first post says NVIDIA does not support default extension blocks and will ignore all changes if a default extension block exists. I don't know if NVIDIA broke something recently because CRU is supposed to be able to read the extension blocks.

Thank you for response. Idk if i understand you correctly, but i also tried with all default extension blocks are deleted and instead added my custom refresh rate resolutions. There is no default extension block left in cru. But still cant see anything from windows or nvcp. My driver version 531.41.

If I may ask a different question. I have the GPU memory locked at max freq (2000Mhz in my case) and also dealing with some input lag (some gpu drivers way worse than others) and I am thinking to use another mode to see if GPU memory will go down

I found that some people fixed this using a different timing. Is there a risk running pixel clock at 346 vs the max reported(330 in my case)? I attached what it looks like if i chose that timing. Am I understanding correctly that the monitor is being instructed by the OS on how to operate by altering the registry? Or its a gpu driver change as well?


Also would this have an impact of how fast the image is being displayed right? Could this add / remove some perceived input lag? I'm troubleshooting Rocket League and its a very fast paced game

If this would fix the gpu memory issue with no impact in games it would be nice

Technically more blanking means it spends less time visibly refreshing and more time between refreshes, but the difference is miniscule and not worth worrying about. CRU creates EDID overrides in the registry, which is basically a description of what the monitor supports. It's not really altering anything in the registry since there's no override by default. The GPU driver will use the override if it exists. Otherwise it uses the monitor's EDID.

Thank you this is very informative and I can actually use this to maybe design some more tests.

And yes the default and custom resolution settings are identical at 120 Hz

Have no idea why the image looks better now

For anyone with LG C2 TV that want to set ultrawide 3840x1600 on their RX 7900XT - these are settings that worked for me in Adrenalin (CRU settings are still ignored on 23.4.1).

I keep trying to do that and eventually succeeded. Dont exactly know what fixed it (whether deleting all other default extensions al resetting repeatedly). Now i did manage to add 144hz i still have no luck with 165 hz. strange. Still success. Thank you for your help and awesome program!

i have an alienware 360 hertz monitor and i cannot get active res same as detailed res any idea??

Hi everyone.

I have a monitor Benq ex2870q which i wanted to remove tv resolutions to use DSR.
Cause DSR vas using 4k 60hz instead of 1440p 144hz:



It use to work fine, but i have updated my CPU, 5800x3D and now i get a black screen when i do that.
I tried to remove just individualy the 4k resolutions, tried to delete them all... i always get a black screen. Seems like it is messing with my default resolution or something.

I tried to reinstall Nvidia drivers, same result.

Do you know what is happening? Or where can i see some clues?






When i restart in safe mode y see 3 monitors, is that supossed to happen? What is going on.







Update, i just reinstalled windows 10 from the begining and same result. I just installed armoured crate, drivers and nvidia drivers 531.68 noting else.



**************


Update 2. I managed to make it work but i don't know how because i was trying so much stuff.

- I went back to driver 531.61
- On bios i forced Gen4 on PCIe
- I change Display Port 1, to 2, i mean the wire. Then i saw 2 monitors on CRU, so i removed tv resolutions and copy paste the configuration to both monitors CRU showed.
- It worked, then i switched to DP1 and it worked too.
- Then i updated to 531.68 and still works.



So i don't know what is the problem. Maybe my GPU is doing something weird with Display Ports? it is a new GPU 4070.
















Thank you!

Hello everyone,

I have a PC connected to a Philips 4K TV (50pus8505) via HDMI. I would like to change my videocard to play at 1440p but when I'm trying to switch to that resolution I can see that the active signal becomes 4K instead of 2K:

Using CRU I can see this:

It's possible to do any configuration for my TV to support 1440p?



Thanks,

I still have problems with my setup.

I have the Benq 27" 1440p 144hz on display port and random DVI 1200p 60hz monitor on HDMI port ( i have bought a dp to dvi wire).

GPU is 4070. Seems that i have fixed the Benq problem by removing tv resolutions on all 3 monitors CRU showed.
I can connect the second monitor, all works fine, but if i reboot, i get black screen, not just black screen, i always get the PC crash. I can only reboot and boot in safe mode.
But if i boot with only the Benq on DP i can boot ok.

I have a puzzler. I have a 2048x1152 monitor that I am able to use 23.976 Hz on at the resolution of 1920x1080.

I haven't had success at doing the same at native resolution. I didn't set up the parameters for 1080p, it just works and not from the graphics driver because there are no custom resolutions defined. My assumption is that they were already defined in the blocks.

Is it possible for me to reach 23.976 Hz at 2048x1152 instead of 1920x1080?

Horizontal frequency range.......30-92 kHz
Vertical frequency range.........56-85 Hz

I'm also puzzled because if the vertical frequency range is 56-85 Hz, then how am I going lower than that? 23.976, 24, 25, etc. all work at 1080p.

Thanks!

That means the resolution is being scaled by the GPU. If your TV can display 1440p, then you can add it as a detailed resolution using CRU, and it will be sent to the TV if GPU scaling is disabled.
