Custom Resolution Utility (CRU)

I've been using it for years, always adding detailed resolutions for my monitors (currently 34GK950F), but now none of the changes I make in the tool are taking effect.. when they used to before I updated my drivers to the most recent ones at time of writing. Was using a driver about ~5 months old before this.

If I follow along with deleting the default extension block, it completely screws up the resolution list, throwing a bunch of resolutions into a separate section in the NVCP and only showing 60/75/100Hz for the other resolutions (including native), when there should be 120/144Hz as well.

And it's also showing a duplicate non-present monitor in the list, which re-adds itself after being deleted (either via device manager or CRU) and restarting the driver.

I don't know what the hell is going on, but adding a custom resolution in NVCP works as expected, almost like CRU used to (shows as a "custom" resolution instead of a native one).

You need to delete the default extension block, and then add a DisplayID 1.3 extension block with the detailed resolutions for 120/144 Hz. The default extension block issue has always existed with NVIDIA. The duplicate monitor entry gets created after running restart.exe and is not a problem.

GTX 980 MSI

I can't do anything about that. The driver crashing would be a driver bug.

I did a few tries with CRU via Detailed Resolutions testing different modes for timing, none worked with 100hz, not even 75hz I can get to work.

The TV probably doesn't support higher refresh rates with non-CTA resolutions. Try 2560x1080 @ 100 Hz with "Automatic (HDTV)" timing.

Did you check the extension block?

I think the only remedy is to limit the fps when raising the lower limit of lfc. Unfortunately, however, I cannot raise this limit higher than 48 hz. Is there any way to get to 60 hz (120/2)?
Another problem concerns the lower limit of the lfc. From 40 hz you can't go down even to 39 hz because of the black frames.
Is it possible to change any other CRU parameter that will allow for example 35 hz to be obtained?

HDMI 2.1 VRR doesn't support minimum refresh rates higher than 48 Hz. The TV probably doesn't support VRR below 40 Hz.

Hello,

I have an old laptop with an i3-3110M and HD 4000.

When I open CRU, it directly show me my screen resolution of 3440x1440@50Hz in "Detailed resolution", it is a 144hz screen but my other recent laptop also can't go higher than 50Hz so it's fine to me.

I did the export solution for old intel CPU and then use the restart and restart64 but nothing change, the higher it shows is 1920x1080.
I also tried different combination of resolution and refreshrate and nothing shows up.

I tried to use multiple versions of Intel Graphics control panel and they don't show higher resolutions either, if I try to set it up manually it tells me it fails.

Do I have to use "Extension block" ? You wrote that intel can't read it so I'm not sure.

I read a few of your replies and you said that some laptop don't allow EDID modification and an other reply saying intel broke it, is it up to date informations ?

Also this is a custom Windows 10 installation so there shouldn't be any weird limitation to the OS.

The model of the laptop is the Portege R930-14E, if it is of any help.

Also, there isn't a single 21/9 option even at lower resolution, I wouldn't mind going for a lower resolution but the aspect ratio is what bother me the most and I'm not sure if it is possible to do.

Anyway thank you for still supporting this tool after all these years!

Hi, I have an Iiyama S2820HSB-B1 (28' stretched). It normally has a resolution of 1920x360 but in windows it is recognized as 1920x1080. It seems that they use some kind of special process to cut those monitors in half. I've used your application and the issue is that it gives me the correct resolution... but it starts from the middle of the screen (meaning I can't see anything). Is there a way of resolving this?
Thanks in advance!
Joris

HDMI or DisplayPort?

Try keeping 1920x1080 as the first detailed resolution. Then add 1920x360 and enable GPU scaling.

Sorry, important information, a HDMI 2.0 cable, the same cable that I use with my more recent laptop that can display 3440x1440@50hz
