In test ufo existing one interval in one block too other block, existing any solution for this? maybe in automatic options on CRU...sorry my bad english

If the TV skips frames, there's nothing you can do. Usually if a TV supports higher refresh rates, it will support 120 Hz. If it's a 60 Hz TV, then usually they skip frames at higher refresh rates and only display 60 frames per second regardless.

However, I couldn't get it worked on my HP AiO PC with latest Windows 11 installed. i5-8500, no independent GPU.

After I added a custom resolution (refreshing rate), I couldn't find it in the setting. Not sure if that because it is an AiO pc or because the OS is Windows 11. I checked the aida64 and the connection was DP.

All-in-ones are basically like laptops internally, and Intel's driver doesn't allow EDID overrides for some laptops for some reason.

I get 165hz using 1440x1080 or 1728x1080 and others custom resolutions,
buuuut, the frames in tests always jump 1 to 1 =(
It's how you say, only 60hz the frames works perfect, the 60hz up the frames jump
Now i using 120hz in 1440x1080, the frames jump but i feeling more better and to get 12bpc.

Hi there, I get this white box when I try to use 320x240 in CRU on a CRT TV with crt emudriver on a radeon hd 5450 via hdmi to component video and I have no idea why.

Please see attached pictures showing the issue and my CRU values.

I’m a total newbie at this so I am learning as I go! I have no idea how to get rid of it as I’ve tried adjusting about every setting. Is there any way to fix this or am I going about this all wrong?

Also I do have a working super resolution for 2560x240 but I also need 320x240 for something that just won’t play nice with super resolutions.

Thanks so much!

Is it possible to use this utility to disable the HPD events from monitors or TVs?

For example, every time I turn on my second monitor it generates an HPD reset (HPD on->off->on) which causes issues with windows and other things.

I also have the same problem with my LG C1 connected to my PC using HDMI.

I've been attempting to add custom resolutions for an external monitor on my laptop and none show up in the windows display settings or intel display settings. I've seen random thread replies regarding intel 9th gen UHD not working with CRU while others say it does. Haven't been able to find a clear guide on what to do and how to make it work if it doesn't.

My monitor has a refresh rate of 165hz, I'm using hdmi though so the native 1440p res would probably cap at 120hz? despite that none of the available options exceed 60hz.

CRU should work for external monitors. Intel 9th gen only supports HDMI 1.4 capped to 300.99 MHz pixel clock.

No, you would need an EDID emulator. If the issue is windows moving around, try using this: https://github.com/kangyu-california/PersistentWindows

The problem is a VGA standard 320x240 would need to be quadruple-clocked or double-clocked with double-scanning to make the pixel clock 25.175 MHz, but there's no way to create such resolutions in Windows. 2560x240 emulates 8x clocking but that distorts the aspect ratio as you've seen. Have you tried a large amount of blanking, such as making the totals 800x525? If that doesn't help, then 640x480 with integer scaling would be the best compromise.

Well I gave it a try but then saw it put it to 31.5 khz. My tv is standard definition so I ended up getting a double image (see attached picture) and cannot use 640x480 progressive (if that’s what you meant). Can I still use this method on my tv with different values? I’m guessing I’d need to keep it within the 15khz range?

Thanks so much for taking a look into my issue I really appreciate it.
