Custom Resolution Utility (CRU)

All the videos complicate things with unnecessary steps. The easiest way to stretch is to use GPU scaling and add the resolution you want with SRE: https://www.monitortests.com/forum/Threa...Editor-SRE

Some people think GPU scaling adds lag, which isn't true, but if you want to use display scaling instead, then you need to add the resolution you want with CRU, restart, and try setting the resolution in the Windows display settings.

You shouldn't get a black screen after restarting if you didn't delete any of the existing resolutions unless the driver crashes, but then it should be fine after a reboot unless you're running into a driver bug (NVIDIA has issues on some systems), in which case you should boot Windows in safe mode and run reset-all.exe and just do the GPU scaling way with SRE.

If restarting is fine but you get a black screen after changing the resolution in the display settings, that means the monitor doesn't support the resolution, so you'll have to use GPU scaling. Windows will automatically revert the resolution if you don't confirm it after 15 seconds, so no worries there.

The only issue is if you have an NVIDIA GPU, sometimes it won't give you the display scaling option when it should (another NVIDIA driver bug), so people end up just deleting all the other resolutions except the one they want. Regardless of what happens, you can always boot Windows in safe mode and run reset-all.exe if you can't see the screen.

The dock equips with a PS186 DP to HDMI micro-chip, which supports DP1.4 input and HDMI2.0b output. I enabled the 4-lane DP alt mode in the dock configuration menu.

I set 4k refresh rate in Display ID 1.3 slots. The highest refresh rate I can get is 67.5hz. Any rate higher than that would not appear in the Win11 display drop down list. Looks to me it is somewhat related to 600MHZ pixel clock limits of the dock.
So, my question is - Is there a way that I can override this limit and force a higher refresh rate for my 5440?

That sounds like a graphics driver-imposed limitation because DisplayPort 1.4 HBR3 should support up to 1080 MHz pixel clock at 8 bpc. If there are HDMI data blocks, delete them since they aren't needed for DisplayPort. If the range limits is included, set it to 1080 MHz. The driver might be listening to one of those.

Tried both suggestions, no avail. Still don't get the refresh rate in the drop-down list. Anything else that graphics driver may be listening to?

BTW, I suspect that the dock may pass 600MHZ pixel clock limit to the laptop, because it only has a HDMI2.0 downlink port although it has a DP1.4 uplink port.

Hi ToastyX, wonder if you have further input to this? Thank you.

600 MHz is not a DisplayPort limitation, so this is probably being limited by Intel's driver. This is something Intel would have to fix, and they probably won't. You can try asking their support anyway. They will probably blame the monitor being HDMI 2.0 reporting a 600 MHz limit even though it works with the other laptop. It's possible to define 3840x2160 @ 120 Hz as a 4:2:0 resolution in the CTA-861 extension block, but the driver might only accept that with a straight HDMI connection, if at all.

OK, thank you for the reply. That makes sense to me.

I recently bought a new monitor https://www.lenovo.com/us/en/p/accessori...e.com%252F and for somereason i cant get ANY res to work. I have followed instructions perfectly and everytime i add a custom res or even keep it normal res the highest one it shows is 240hz. It wont let me change it to 360 but sometimes it does? IDK but no matter if i leave it at 240 or 360 when i restart and then go tom list all modes in windows my monitor goes black and goes into stand by mode. Is my monitor not supported?

Monitors with the NVIDIA G-SYNC processor only support a limited set of resolutions. You'll have to use GPU scaling.

I'm trying to remove the TV resolutions on the GM001J, but the extension blocks are gray and can't be edited. Is there a work around for this?

downloaded the zip file instead of the exe, these three exe's bring up the old intel hd graphics control panel, where i'm able to set my custom resolutions

Hi.
Need a little help with new monitor please.
Samsung Odyssey g70b/hdmi 2.1 connection. If adaptive sync on - sometimes on switching full screen to borderless have black screen. Audio - working. Just full lost of video signal.
Cure - disable adaptive sync in monitor setting, thats restart monitor and image start showing up.
As i understand after google - need to corect v rate.
But in my scenary - v rate blank.

Extension blocks - empty.
If i understand correctly - i need to add "cta-861" block and use "freesync range" option with what numbers? Something like "60-144?"
Or i need "hdmi 2.x support" and "Variable refresh rate" range option ?

Are the extension blocks empty or do they say default extension block? If default, is this with an NVIDIA GPU? NVIDIA's driver ignores EDID overrides for displays that have the extension block problem, so you won't be able to make any changes until they fix this. Frankly you shouldn't need to use CRU to fix a problem with a new monitor. This sounds like a firmware bug with VRR that Samsung needs to fix, so you should report this issue to their support, or return it and get a different monitor without this problem.
