Custom Resolution Utility (CRU)

I assumed I had to redo it because it didn't show up in the Detailed Resolutions sections after I had added it. Knowing that I tested multiple resolutions on 360hz using Automatic(PC), Exact, Exact Reduced, and a couple of others that I didn't really expect to work. The main two ones I tested were 1680x1050 and 1728x1080 when the former didn't work. That being said, every single test resulted in failure with the monitor just showing that it was going into sleep mode. I saw somewhere that G-SYnc monitors usually can't preform out of some set of presets, so I guess i'd have to find a resolution thats already in one of those?

Make sure GPU scaling is enabled. 1680x1050 should already exist as a scaled resolution by default.

Your card doesn't seem to support HDMI audio through the DVI port, so you would need to get another card with HDMI, or you can output audio separately using the line out on your sound card or motherboard.

Is there an adapter that would combine the DVI video and 3.5 mm audio from my computer and convert that to an HDMI that I could input to the tv? Or similarly DVI + spdif optical to HDMI? If that's not possible, could you recommend a reasonably priced graphics card that would be able to stream up to 4K video comfortably? I don't do any gaming, so that should ease the requirements a bit. Thank you kindly for your advice...

Hi,

I've tried everything and I can't fix the high vram clock issue...

I have a RX6800 and two screens :
- 1 16:9 BenQ XL2730Z : 2560x1440@144Hz
- 1 21:9 Xiaomi Curved 34" : 3440x1440@144Hz

Each screen used alone : I don't have the high vram usage problem (around some Mhz and 6-8W power consumption at 144Hz for each scren used one by one).
But when I plug the two screen at the same time the vram clock at 2100Mhz and the power consumption jump to ~40W.

Do you have some advice ? I tried switching to 142 Hz or 120 Hz on the two screens at the same time and this didn't solve the issue.
In CRU i've tried to apply "Automatic (PC)" timings from the extension blocks section for each screen but it didn't fixed the problem either.

I think the issue is related with the mix between one 21:9 3440x1440 screen and the other one at 16:9 2560x1440 (but maybe i'm wrong).
I searched on Reddit and on this topic and tested everything i've read without any success...

Do you have any idea ?
And btw do you know why, with the 21:9 3440x1440 monitor, when I go to detailed resolution section, I can't set a refresh rate higher than 119Hz (higher than that, the refresh rate became red and I can't press the OK button) ?

Thank you for your help, CRU is a great tool that helped me many time by the past but this time I don't know how to solve the problem.

The monitors need to be perfectly synchronized to change the memory clock without screen corruption, which is hard to do when the resolutions are different. Try setting both resolutions to "Exact" timing.

Thank you for your reply !

I've tested with "exact" timing (see the screen below) but it didn't solve the issue.


Any idea ?

Hey Toasty,

Is there anyway to force enable dolby vision using the EDID modifications?

I don't think so.

Try changing the horizontal total for 2560x1440 to 3600 to match the other monitor. Then they should be perfectly synchronized.

Hi ToastyX,

When i try to change the horizontal total to 3600 I can't confirm the configuration.



If I set the refresh rate below 117Hz I can confirm, but the Vram clock is still locked at 2100Mhz.

Hello Gals and pals,

Maybe this question was answered before, but I'm in big troubles here.

I've been receiving a laptop from my work (Lenovo T14 Gen 1) and I have a C49RG90. I used to have it with my old company's computer, and it worked fucking well.
Now of course with the T14 and it's built-in Intel UHD620 it's not working.

No resolutions are correct, everything is pixelated.

With Intel Graphic cards utility I can add a custom resolution of 5120x1440@30hz, but then the image is not well at all.

I've seen some people managing to get that screen working correctly, I tried using CRU.exe but the resolution does not appear.

When I try to edit either the Detailed or standard resolutions, it does not allow me to add a 5120x1440 (going red).

When I use the extension bloc (either 1.3 or 2.0) the resolution will never appear in the windows menus.

any ideas if what's i'm trying to do is possible ?
