Custom Resolution Utility (CRU)

I am using an LG C1 OLED and with 120hz and BFI it is possible to use this TV with the old Nvidia 3D vision glasses and the effect mostly comes together but there is still some cross talk. There is a utility made to allow you to fine tune the timing between the glasses and display to help mitigate this and in order to use it you have to change your TV's monitor ID to be the same as one of the official 3D vision displays that came out. So I used CRU to go in and change the ID of my TV from what it was "GSMC0C8" to that of a reccomended 3D vision display "VSC591E" and after restarting I encounter a bug of sorts. As long as I leave the ID changed I cannot whatsoever get the "active display resolution" to change in Windows, it is stuck at 4096x2160 if I choose 120hz and 3840x2160 at 60hz and below. I check CRU and make sure all my other resolutions are still in the EDID profile, and restart the displays again but nothing, if I use Nvidia Control Panel to set a custom resolution even when entering all timings manually it still goes right to one of those two resolutions. What can I do to keep my TV functioning like normally but still be able to change this monitor ID? Thanks again

NVIDIA's driver seems to disable display scaling for certain IDs, possibly to make sure 3D works with all resolutions. I don't see a way around it because it seems to be hard-coded in the driver.

Whitelisting in Kodi makes no difference. Behaviour seems the same whether Intel GPU drivers are set to 8 or 12 bpc, RGB / 444 / 442…

I don’t really understand the difference between “detailed resolutions” and “TV resolutions” - do I need to be adding 1080p23.976 as a “detailed resolution” as that is a different refresh rate to the 24fps shown in the “tv resolutions”? Or do I misunderstand?

I guess what I would really love is a simple, generic .bin file that tells Kodi that I have a TV which will accept 1080p and 2160p resolutions at all normal frame rates, as well as DD/DD+/TruHD/DTS-HDMA audio formats. Does such a file exist and might this help?

TV resolutions are CTA-861 standard resolutions intended for TVs, while detailed resolutions let you define custom timing parameters. TV resolutions are supposed to include both refresh rates, but that's up to the driver. If the driver added both, you should see both 23 Hz and 24 Hz listed in the Windows display settings. It's not possible to define both with detailed resolutions because Windows will consider both to be 24 Hz and only use one of them. Is 1920x1080 @ 24 Hz available in the Windows display settings, and is it scaled correctly? If so, the problem is on Kodi's end. I can't make a generic .bin file because I don't know what your TV supports. Do you have a copy of the TV's original EDID and the changes you made?

I wanted to try overclocking my 240 Hz Monitor, I used the automatic option and the reduced timings but I was only able to get around +3 HZ increase. So I did a some manual timing using Nvidia Control Panel where at 1920x1080 I set all the porch and sync values there to 1 and reduce the "Total Vertical" to 1085 and managed to get 260 Hz. I tried reducing the "Total Horizontal" as well but even a single adjustment resulted in a black screen so I did not touch that. My question is, is there any downsides into using the method I did above? Keep in mind I don't need or use V Sync or G Sync, just wondering if there is any downsides and a way to maybe improve even further by lowering the Total Horizontal.

The only issue is the GPU's memory clock can't clock down when idle if the vertical blanking is too low. For horizontal, don't change the front porch and sync width to 1. Horizontal values are usually multiples of 8, so they probably need to be at least 8, and the sync width is normally 32 for CVT-RB.

Thanks this got me on the right track. I just went ahead and removed all other modes but the one I needed from the EDID and it worked great

Hello I recently tried overclocking my computer screen I followed some videos that shows how to do it with one of your programs but the problem and that if you have any idea how
to repair it . I can write to you, the screen is white with black bars I tried to do everything like restart ,look in the bios, nothing can be done the screen remains frozen I tried everything but nothing and also I did it on a laptop
So if you have a solution answer me

Can you see the BIOS/EFI screen and the boot screen before Windows starts?

I can't see the bios and the sreen

Then it sounds like the screen was damaged somehow. What laptop do you have and what exactly did you do?

What resolutions did you add? At what point did the screen turn white with black bars?
