Custom Resolution Utility (CRU)

[spikespiegel]

I have a pc with a nvidia card and intel hd graphics, my dedicaded graphics card does not have any vga ouput, so I'm using my motherboard vga ouput (intel hd graphics) to connect to a CRT tv that I've rgb modded, I've used CRU to change the signal frequency, image size, vsync, back porch, etcetera, the problem is that, although I'm being able to see the image, the image is multiplied and moving up fast, as shown in this video:

These are the settings I've tried. I've even lowered the resolution:


The TV is a TC-29FX32L

Hi,

I have had a long standing problem with my Samsung TU7 (UE43TU7110KXXU) where even though the native resolution is listed as 3840 I found I like the look of games @ 4096x2160. The TV sets various things at that resolution that just can't be set in other resolutions because Game Mode usually locks the settings out even though Game Mode is still on @ 4096. I perceive a clearer image and better more punchy colours. But with AMD Integer Scaling (IS) it refuses to switch the Active Signal Resolution to 4096 with a resolution of 2048x1080. It selects 3840. I've tried the usual guides for how to remove the 3840 resolution. But then, even though AMD is forced to select 4096 its 4096 @ 24hz ! With Vsync turned on this is just too low an FPS for games. Without IS I can select a full 4096x2160 @ 60hz and everything is fine. But of course that's too hefty for most games hence the requirement of having Integer Scaling. What am I missing here ? Is it something to do with CRU or AMD IS ?

Cheers.

CRU does not currently have a way of setting the native resolution to 4096x2160.

More than likely the TV is enabling or disabling certain image processing features with certain resolutions or timing parameters. First, I would try to replicate that at 3840x2160 by removing all references to 3840x2160 and 4096x2160, and then try adding 3840x2160 @ 60 Hz with "Automatic (PC)" timing as the first detailed resolution. The TV might treat that differently and give a better picture.

If that doesn't help, then try 4095x2160 @ 60 Hz and see if it behaves the same as 4096x2160.

If that still doesn't help, then try removing all resolutions and add a DisplayID 1.3 extension block, and then add 4096x2160 @ 60 Hz in the extension block as a detailed resolution.

Thanks for this . I'll give this a try tomorrow.

Did not work. Can't see image processing features added to 3840.

Adding DisplayID. The Samsung display refused to display anything.

I put in a ticket to AMD about this which forced me to define the problem better. AMD Integer Scaling will always choose the "native" resolution because that's the whole point of Integer Scaling. So I really just need to flag 4096 as "native" when I want to use that. Do you know of any util that can do that ? Cheers.

CRU will be able to in a future version. I will see if I can add it to the next release, but my focus is currently on making the Scaled Resolution Editor.

Run reset-all.exe and reboot. Then export a file for the monitor using CRU and post it here. I will come up with some configurations that you can try.

Thanks. Bin file Attached. Finally settled on turning Game Mode off for 3840. It looks better and I can't perceive any difference to the latency. This TV has some eccentricities !

It looks like 3840 is in fact the true native res. I was thinking it might have a "true" native res of 4096 for 4K DCI cinema and only shows the computer 3840 as "native" because some games don't do 4096 very well. But I don't think this is the case. But I'd still like to experiment with 4096.

I just want to try the suggestions with no other resolutions present.

This one has 3840x2160 @ 60 Hz with timing parameters similar to 4096x2160:
  3840x2160.bin (Size: 256 bytes / Downloads: 392)

This one has 4095x2160 @ 60 Hz with timing parameters similar to 4096x2160:
  4095x2160.bin (Size: 256 bytes / Downloads: 346)

This one has 4096x2160 @ 60 Hz in a DisplayID extension block:
  4096x2160-displayid.bin (Size: 384 bytes / Downloads: 387)

If none of those help, then I will make a file with the method that will be supported in a future version.

Hello guys!

Long story short, I got a second hand 32 inch 1360x768 tv from a friend, my GPU has only one HDMI output and three DisplayPort outputs, so I bought a cheap DP to HDMI converter, it works fine, the only problem is that windows doesn't reconize the correct inch size and it's really bugging me out, is there a way to use CRU to edit the size in EDID and correct it to 32 inches?

Anyways, thanks!

What uses the size in the EDID other than the default scaling size? You can set the correct scale in the Windows display settings.

CRU doesn't have a way to edit the screen size directly, but you can export a .bin file and use another EDID editor to edit the size. Then you can import the file with "Import complete EDID" enabled to load the new size.

You can use any of these editors except Phoenix: https://www.monitortests.com/blog/list-of-edid-editors/
