Custom Resolution Utility (CRU)

[Mr4ssault]

Hello i decided to go with an custom res via nvidia control panel since cru is not working for my monitor. when i select fullscreen and display scaling + override the in game scaling checked is it still gpu scaling then? Because i override the in game scaling so it should be display scaling since it is selected in nvidia control panel right?

The native resolution isn't scaled.

The same timing parameters work exactly the same with both CRU and the NVIDIA control panel. The monitor should tell you what resolution it's receiving in the menu somewhere. If it doesn't match the resolution you selected, then it's GPU scaling.

Why are NVIDIA users so obsessed with display scaling? I don't understand where this obsession is coming from.

Just for information, I re-ran DDU, re-installed latest AMD Drivers, but still my custom resolutions are *not* showing is the list under Windows 22H2
I don't think the issue is specific to CRU though - as previously mentioned, custom resolutions made from within the AMD Adrenaline software also do not show

Are you using any remote desktop or mirroring software? What is the monitor listed as in Device Manager? Do you see any display adapters listed other than the AMD GPU?

But as I said, Nvidia CP and Windows keep seeing the EDID as it was originally.

That doesn't make sense. You said the TV with the adapter isn't detected by default, so there is no original EDID. It has to be using what you loaded into the NVIDIA control panel. It's impossible for it to be anything else. You can use any EDID editor to see the exported file has the changes you made.

Unfortunately it makes sense '^^

There are 2 TVs I'm referring to in my latest posts:

1. the SD-CRT (Mivar 28S4 Stereo) I'm trying to connect the PC to using the UMSA

2. the HD-CRT (Philips 32PW9551/12) from which I extracted the EDID as a base

Let's recap:

- I connected the PC to the HD-CRT (it obviously has an EDID) through HDMI and extracted the EDID (2 files, one using nvidia cp and the other using CRU, as I writed on a previous post, they seems the same).

- I modified the EDID and loaded it on the DVI-I port which is connected to the UMSA that's connected to the SD-CRT

The issue is that the PC sees the EDID as if it was un-edited. I can see all the HD-CRT resolutions as they originally was. I have modified most of them, for example the main resolutions were 1920x1080i / 1280x720p and I replaced them with your suggested one, 1440x480i and 1440x576i. But the PC keep seeing the original resolutions.

Should I make an EDID from scratch, is that even possible?

As you guessed it is probable I didn't edited the EDID correctly, could you please check it?

There 2 editings I made, they should be mostly the same: https://mega.nz/file/5RVAhCgB#qT5lQZCgou...X0mkoUgTtI

This is what doesn't make sense. This is impossible because it can only be using what you loaded.

That's because you still have the resolutions in the EDID.

Both of your edits still have 1080i and 720p defined as TV resolutions. Windows might not list 480i and 576i, but they should be available for programs to use if the driver supports interlaced resolutions.

Yes, but CRU doesn't have a way to do that. Here is a basic analog EDID with 480i and 576i:

  edid.txt (Size: 392 bytes / Downloads: 187)

You should be able to load that into the NVIDIA control panel as is. You can also import it with CRU to edit the resolutions.

Hi ToastyX, I don't think this is a cru problem but maybe here can help me out, this is my problem..

I can create a 4k exact resolution using CRU, with let's say we 300 lines of back porch.. when gaming using RTSS, when the sync value is 0 the tearline might or not show up on screen (this is ok), at 1 it shows at the 1/10th of the screen (more or less which is ok), the problem starts here, if you start moving the tearline down you can see the sync value changing but the tearline wont move until you get to 210 (300-90), after 210 you will see the line moving down, the last visible line for the tearline is always 90 lines before the total vertical and the tearline will stay up at the top of the screen while the sync value is lower than the vertical blanking. resuming, no matter the vertical blanking I use (tried with up to 2500VT using CRU) I only have 90 lines below the active image.

Hi, I was wondering if CRU could change Miracast connected wireless display resolution or not? I've already tried but had no luck, as miracast driver settings does not show my custom added 1600x2560 resolution via CRU.

To be more specific: I'm extending my laptops display with Samsung Galaxy Tab S6 tablet, which has 1600x2560 native resolution, but somehow I cant use it, as display setting max is 1440x2560, thus I have huge black lines on top and bottom of my tablet while using it as wireless display.

I see, thank you very much, I'll try your EDID right away. I hope windows will list it, I'd like to be able to normally use the PC on the SD-CRT Tv but perhaps they removed this possibility.

I copy/pasted your values into a TXT file (390 bytes) and loaded it on Nvidia CP. It loaded succesfully on the DVI-I port.

Windows set it as inactive by default (I get "show only on 1" option), I cannot extend the monitors. Tomorrow I'll connect the UMSA and try "show only on 2" option. I'll make you know if it'll work.

Try changing the vertical front porch instead. You will have to use a DisplayID extension block.
