Again, CRU has no control over what resolution is set in Windows, so the version of CRU can't possibly affect that. CRU doesn't do anything in the background, so once you save the changes, CRU's job is done. Windows is supposed to remember the resolution and refresh rate between boots, so something else is causing that to change.

I dont know but didnt happend with 1.4.2 and other versions which are 1.5.1 and .2 my res changed i know isnt a cru thing but its weird

Is there a solution to the black screen after modifying ID serial?

Hi, does this tool support VMs running on ESXi? I added a new detailed resolution of 1728x1080 @ 60 hz. using the Automatic PC timing on a Windows 10 VM. However, even after a reboot, the new resolution never shows up as available for use. There are many other much higher resolutions available but not the one I created using CRU.

Hello everyone, I have this problem: I have a monitor with resolution 1920x1280 and I want to set it to 1920x823 to play in 21:9.

As you know, I have two ways to do this, through the NVIDIA Control Panel and through CRU, but that's where the problem arises:

•Using the NVIDIA Control Panel, setting the Timing values to Automatic, I will have the resolution of 1920x823 in 21:9, but it will be a bit blurred and not defined like 1920x1280.
However, I solved this problem by leaving, through Manual, the same Timing values in 1920x1280.

In theory, I could have solved, 1920x823 is defined as 1920x1280 and I would have my 21:9, but I would like to use the NVIDIA DLDSR, and to do this I cannot use the custom resolution but CRU, and with the latter the second problem arises:

•Setting the resolution of 1920x823 with CRU, it gives me as if small slightly blurred vertical lines alternate with other lines where you can see well, and the thing is quite noticeable with small text.

Now I would like to obtain the same defined result that I get with NVIDIA, I tried to do as on the control panel that even with the resolution of 1920x823 I inserted the timing values of 1920x1280, but on CRU Bach Porch and Blanking always change automatically when I modify Total and I cannot insert for all the same values as the original resolution, because these two always remain different, and therefore I think that for this reason it comes out staggered, that is, it has nothing to do with the screen and with a different aspect ratio

What can I do? Thank you.

The only reason there would be blur is if there's scaling involved. What monitor has a resolution of 1920x1280? Your last statement doesn't make sense. The total is the active resolution + blanking, and the blanking is the front porch + sync width + back porch, so the values are supposed to change. NVIDIA only shows the total and not the back porch or blanking, but there is no difference because you only need one of them to calculate the other two. The resolution you created with NVIDIA is a GPU-scaled resolution because the resolution at the top doesn't match the active resolution that is sent to the monitor. CRU can't create GPU-scaled resolutions, so the active resolution is sent to the monitor unless GPU scaling is enabled. That means if GPU scaling is not enabled, the blur is coming from the monitor. The monitor needs to be set to not scale the image. If the monitor is set to not scale, then maybe it can't display an odd number of lines correctly, so try an even number. Another option is to enable GPU scaling in the NVIDIA control panel and set it to aspect or no scaling, but if you just want a GPU-controlled resolution, you can use this instead of CRU: https://www.monitortests.com/forum/Threa...Editor-SRE

The graphics driver needs to support EDID overrides. If the VM is simulating a GPU and the graphics driver doesn't support EDID overrides, then CRU won't have any effect. If the VM is using GPU passthrough with an AMD/NVIDIA/Intel GPU, then it should be possible with the appropriate driver installed.

Modifying the ID serial number shouldn't cause a black screen. Only a graphics driver bug would cause a black screen in that situation.

I have bought an GTX 1660 Super and as some people know, NVIDIA disabled interlaced output from Turing, I read somewhere that using an secondary old AMD GPU like this Ati Radeon HD 6450 you can use the NVIDIA card as rendering one while you use the Ati Radeon as output, well, my motherboard doesnt have an second GPU slot so Im using a riser, I have installed both drivers, but before I uninstalled the old ones with DDU, after that plugged my two monitors into the Ati Radeon, seems to work but when I start playing or just play a video, it becomes very laggy and the Ati Radeon raises it's temperature, at the same time is like is sharing computational work with the GTX and makes performance horrible, any suggestion?

My idea is to use an Samsung CRT Syncmaster 796MB at 1600x1200i 100Hz

Trying to understand why my Nvidia 3070, connected to a LG C1 television, is apparently unable to accept fine adjustments to refresh rate.

I use pixel clock calculator after deciding what specific refresh rate I need to avoid repeated/dropped frames during 23.976 playback but it seems that the card either does 23.97618 or it jumps straight to 23.977xx.

Am I missing something? Is it a known problem with new drivers?

I am on Windows 10 Pro x64 21H1, Nvidia drivers 528.24, if that matters.

Hey ToastyX! Is there such thing as Cvt-RB3??
