Custom Resolution Utility (CRU)

[cyrb]

Hi there,

I have encountered an issue related to Windows 10 - it seems Windows 10 is ignoring changes that have been applied.

I have a TV with a resolution of 1360x768 which supports a fake "1080p" and "1080i" mode. Some games cause this resolution to be triggered when using full screen, which looks horribly blurry and desaturated, while it should be using 1360x768.

I was able to fix this with CRA under Windows 7, because 1080i and 1080p were listed under CEA-861, under the 'detailed resolutions' as well as a 'TV resolutions' data block. Deleting the references to 1080p solved the issue.

On Windows 10, CRA doesn't seem to even show this information, as it shows no extension blocks being used. I copied over the .bin file from Windows 7, which populated the extension blocks with the fixed information, but this had no effect and seemed to be ignored - the affected games still used "1080p".

This sucks after I got it fixed on Windows 7 just for it to not work on my main OS. Any suggestions or explanation?

Cheers

The GPU is NVIDIA GeForce 840M (laptop GPU). The Windows 7 machine is NVIDIA GTX 1050 Ti

This is what CRA shows in the affected Windows 10 machine:

This is what CRA shows on the Windows 7 machine:

I used reset-all before getting screenshots. Deleting the instances of 1080p or 1080i addresses the issue, but exporting this and importing it does not have an effect on Windows 10.

You didn't say these were two separate computers. This is not a Windows 10 issue. You said the Windows 10 computer showed no extension blocks, but your screenshot shows a default extension block. That just means CRU can't read the extension block with your laptop. Copying the settings over from the other computer should have worked unless the driver doesn't support EDID overrides. Try deleting the extension block.

Hi Toasty,

I run a laptop with an Integrated Intel ® HD Graphics 4600. It also has a NVIDIA GTX 970M. Connected to a Monitor with native resolution 2560 x 1440p @ 144hz (OC 165hz).

Running mDP to DP cable 1.2 and can only achieve 120hz. Even if I reduce the resolution to 1080, 768, the refresh rate remains the same at 120hz. I've tried everything from display settings, reinstalling drivers, nvda control panel, intel control panel etc.

In addition, desktop resolution changes but active signal resolution remains at 1440p.

Will the CRU assist or am I doomed?

Your Intel GPU is probably too old to support the full bandwidth.

Your Intel GPU is probably too old to support the full bandwidth.

According to Intel® HD Graphics 4600 from Intel's website:
https://ark.intel.com/content/www/us/en/...0-ghz.html

Graphics Base Frequency 400 MHz
Graphics Max Dynamic Frequency 1.20 GHz
Graphics Video Max Memory 2 GB

Graphics Output
eDP/DP/HDMI/VGA

Max Resolution (HDMI 1.4)‡ 3840x2160@30Hz
Max Resolution (DP)‡ 3840x2160@60Hz
Max Resolution (VGA)‡ 2880x1800@60Hz

If it supported the bandwidth, then it should work out of the box. The monitor already defines 144 Hz so using CRU won't make a difference.

Hello to ToastyX and anybody else in this forum.

I've just upgraded my PC from Win 7 with old Gigabyte MoBo Intel Core quad and GPU nVidia Quadro 1500 to a new Win 10 x64 setup Intel i7, Asus ROG Stix Z390, RTX 2070 Super.
I have a dual 24" monitor configuration (LG 24MB67 connected to DP + LG L245WP connected to HDMI)
Both are configured in Window to display at 1920x1200 @ 59.950Hz

The first monitor looks great!
The second one, not too much...
The desktop is stretched horizontally a bit and the entire desktop is shifted to the left for about 120 pixels and to the top for about 20-30 pixels.

I tried to connect it to a different PC with a different HDMI cable but i got the same exact result. So the problem it is not related to GPU or cable i think.

I heard about EDID information 2 days ago and i have understood the problem could be about corrupted info sent to GPU card from monitor.
So i launched CRU but I'm a totally newbie at it.
Is there an official manual for it?
I really would like to know more about the gui sections and how them work.
Anyway, having you here ToastyX, i kindly ask you to help me to fix the problem.

I have attached 4 images about CRU (2 x monitor).
I noticed the good displaying monitor has the native configuration 1920x1200 in the extension block, while the bad one not.

Thanks a lot.
