Hey everyone,

I don't know where the help desk is but I'm sure Toasty would know the answer to this.

[align=justify]I tried overclocking my 144hz monitor through the Nvidia Control panel and it seems to go to 182, but I didn't see any intrinsic difference. I tried using CRU to see if the 182 would be "activated" in a sense and so I selected my monitor (my 144hz is connected by Display Port) and then both of my monitors (one DVI and one Display Port both connected to 10606GB) went black. Now I have to use my HDMI for my 144hz and it's capped to 120hz. Whenever I plug in my 144hz it just goes black and my other monitor freezes. Is there any fix to this? I tried taking out the battery inside the motherboard and plugging everything out for a couple of minutes including the socket on the wall.

Thanks,
Vex

Did you run reset-all.exe? What changes did you make? Are you using the latest NVIDIA driver?

Thank you so much Toasty.
That driver got the resolution back right away!

Trouble is it's doing all other kinds of weird stuff with coloured blocks slowing the machine.
I guess it's not quite the right Driver?
I'd already visited the Packard Bell Suppport Site with a view to updating Drivers ..... but they say "service is unavailable" atm!

I think reverting to Win 7 & seems the only option?

That's the last driver available, but it's made for Windows 8. NVIDIA stopped supporting the GPU after that.

Since windows does not allow change of Pixel format, can i change the default format in CRU?
Monitor seems to default to YCbCR instead of RGB, which results in washed out colors.

Hey,
i've got an issue and i hope someone can help me with that.

Got a Lenovo Y27q-20 with a Native Res of 2560x1440 on a Nvidia 3080

My problem is, that the Monitor also accepts 3840x2160 as an Input(the downscaling to 1440p looks horrible btw)

Some Games choose the highest available Resolution in that Case 2160p and that's annoying.
Same for Nvidia DSR it uses the 2160p Resolution for its Downscaling so its completely useless for me since it outputs the Downsampled Screen at 2160p

Is there a way to remove the unwanted Resolution?
Already tried removing every Trace of it via CRU, but so far i have no luck at all :/

Edit: Problem solved, had also to remove the Greyedout and Empty Default Block

You can change the pixel format in the GPU's control panel. You can use CRU to remove YCbCr completely so only RGB is used. For HDMI, edit the HDMI data blocks in the CTA-861 extension block. For DisplayPort, use the "Edit..." button at the top next to the monitor name, and some DisplayPort monitors also include the HDMI data block.

I thought i could. that's great.
I can't find exactly what i need to change/remove though. I don't want to mess it up. If I upload the file, can you help me with that please? https://www.mediafire.com/file/uoeknaeix...t.bin/file
I'd like to used a 1920x1080 resolution in RGB, instead of YCbCr.
Also does this option require that i have a driver installed? I mean i have to change this info everytime i change drivers? (when amd driver is used as a "minimal install", there is no setting to change the YCbCr to RGB, and that ugly ycbcr is used.)

Hello, I've been using cru for a while without problems. But today when trying a new resolution for my 2nd monitor and clicking "ok" a pop-up shows and says something like "some settings didn't save" or it was something like that, I forget. Rebooted pc, all 2 monitors are active and fine. So I open CRU and it didn't detect my 2nd monitor only shows my first monitor. The 2nd monitor is active and I can change resolution and stuff. So then I try reset-all.exe but CRU still didn't detect my 2nd monitor.

Any ideas on how to fix this?

There must be something in the registry that CRU couldn't process. Use RegEdit to export HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\DISPLAY to a .reg file and upload it here so I can see if there's anything unusual.
