Custom Resolution Utility (CRU)

Pretty interesting because the edid modeline for my panel will report as display 59.876Hz composition rate 59.909Hz. Using CRU's automatic setting will give 59.949 display/60 composition which is nice. Exact will give 60/60.

Exact reduced will give 60.01093 display.

That seems hardware-specific. The Exact modes were only meant to be logically exact. I can't guarantee any particular timing will be physically exact because that's hardware-dependent.

DMT is not formula-based. I only included DMT for 1360/1366x768 and 1600x900 @ 60 Hz. If I add DMT for 2048x1152 @ 60 Hz, it will be part of the Automatic PC/HDTV modes. Exact and Exact reduced will stay the same.

Hello, sorry for my bad English.

I come here after reading a lot and now that I have a monitor I might be able to take some advantage of it.

I know cru for a long time to see the panel, or just the information it displays but never got into it thoroughly, I'm looking for some tutorial to know how I can create more than resolutions, because I'm already looking at 1440p especially to see if I can squeeze the ports to apply more bits, or vrr, or high refresh rates.

I have an Asus Pg329q monitor running at 1440p with a 1080ti Aorus xtreme.

The monitor as it says, and I can not find out more information says that supports HDR, but this monitor has hdmi 2.0 and displaypor 1.2 in your information, inside the monitor says that supports display port 1.2 + hdr thing that is not well what it is, or that protocol is using ...

In addition, this monitor is certified with Vesa HDR 600 and win11 does not detect it.

Also I realize that for the HDMI 2.0 cable the Nvidia control panel does not detect the Gsync Compatible option.

Can you give me some clue or some information about what kind of cable would be more convenient to use? dp1.4 as the gpu gives me to the dp1.2 port of the monitor? or pull by HDMI?

It is curious, when I connect it by HDMI to 1440p at 60hz in windows11 the able to be configured to 12bits but instead by displayport at 60hz only to 10bits.

I would like to be able to activate the Gsync compatible option at least at 120hz or 144hz with 10bits, but I do not know how to do it.

I know it is very selfish of me, is there any tutorial for these things? or information I can read to understand how to create blocks? or see if there are blocks available? and start playing?

thanks and greetings from barcelona

I have a question about output a custom resolution video to a LED wall. The LED wall is in a special resolution 6192 x 2580. If I connect the LED wall with a PC with Win 10 and Nvidia GeForce RTX 3080ti via HDMI 2.0, am I able to output a true 6192x2580 by setting a profile in CRU? I need to output a true 6192x2580 video in order to have a full screen size on the LED wall. Could I set up that special resolution by CRU?

Your reply is highly appreciated, thanks a lot!

Yes, but HDMI 2.0 is limited to 600 MHz pixel clock, so 6192x2580 is only possible at around 30 Hz. Video walls usually use multiple connections.

You need to use DisplayPort if you want G-SYNC because NVIDIA does not support G-SYNC with HDMI 2.0.

• 120 Hz at 10 bpc should be available automatically with DisplayPort 1.2.
• 144 Hz at 10 bpc might be possible with DisplayPort 1.2 if you edit the detailed resolution (might be in the extension block) and reduce the blanking/totals to keep the pixel clock below 576 MHz (with some overhead it might be 572 MHz).
• 60 Hz and 100 Hz at 12 bpc is possible if the max color depth is set to 12 bpc. You can edit the max color depth for DisplayPort using the "Edit..." button at the top of the main window, but the monitor might not actually support 12 bpc. The monitor might accept 12 bpc but downsample to 10 bpc.
• 120 Hz at 12 bpc might be possible if you reduce the blanking/totals to keep the pixel clock below 480 MHz (or 476 MHz with overhead).
  

You shouldn't need to add any data blocks because the monitor already defines what it supports. There are various tutorials out there made by other people, but they often leave out important information and add unnecessary steps. You should read the first post about extension blocks since you have an NVIDIA GPU, and the detailed resolution section has some important information.

Hello Guyz,

I am new here greetings.

I came here because I have problem too with custom resolution !
Thanks to crafty Intel right?
So
I have purchased new laptop 11th gen i7 11800H with an annoying their UHD graphics.. along with RTX 3060 Nvidia as secondary GPU
Now I have hooked it up on mine Samsung TV Q85T 4k@120 .
And from laptop I can only push native 4k@60 only but can't override to 4k@120. If I would have that old intel control center where I could set even refresh rate and monitor timing standard, I would have 4k@120
And as you guessing I am not able to push custom resolution because amazing intel scrapped traditional graphics control panel from right click .. Only my option was to download microsoft store app intel graphics command center . And that poor center surprised me and when I tried to do custom resolution, it only showing width and height and can't do anything.
So I was trying to workarounds in registry adding some strings as on youtube some managed to do it, but no luck for me...
Intel shamefully removed old control panel where I could be able to do full custom resolution.
So lastly I found this software ...
I want to know if this software is supported for Intel 11th gen laptops ? (2021)

Thanks

My main PC recently developed an issue where shortly after boot the display would lose signal and report an unsupported mode (720x480 60i!). For some absolutely bizarre reason I worked out this was happening when the Steam client was starting. I then worked out that if I reset CRU, the issue would go away! I was using CRU only to remove 4096 modes (due to Nvidia assuming the highest mode is the native and scaling not working).

I can't for the life of me work out what the Steam client is doing with video when it starts that could cause this problem and why my CRU edits seem to cause this issue. Any ideas?

Is there any way we can enable "Dynamic Refresh Rate" on Windows 11 using CRU? I'm using a laptop with Intel 12700H with onboard GPU and RTX 3060, outputing to a 165Hz display.

Open Intel graphics command center click on gear - settings then on top window select global settings and you have all stuff there ...

I have IIISi Creator Z16 Hiroshi Fujiwara Limited Edition laptop with intel i7 11th gen 11800H and RTX 3060 And 165hz refresh rate mini LED screen with Full HDR support 1000 nits screen is amazing !

Also check in video settings scroll down and see if you have set 10 bit color depth and color formal RGB .. I think default is only 8 bit .. with HDR off . With HDR on it will auto switch to 10 bit but I have 10 bit even with HDR off.

Only one flaw these laptops has is that cannot enable G-sync on RTX 3060 and I can't achieve 4k@120Hz on mine samsung 4k@120 TV which is really shame

In intel command center, when I click on + next to resolution, it won't give me all full options to set custom resolution which is strange ...
This laptop has thunderbolt 4 type-c combined with display port 1.4 or maybe 2.0 which fully support 4k@120 but can't do it ...
Shame that Nvidia control panel doesn't have full options to set everything same like in desktops ...
