Custom Resolution Utility (CRU)

[fandangos]

Is it possible to add 3840x2160 as a 4:2:0 resolution?
So it would in theory works with hdmi 2.0?

My tv is 4k and can do 1080p 120hz RGB 8Bits so in theory it would be possible 4k 4:2:0 at 120hz.

In theory it's possible, but I don't know if any driver supports 4:2:0 with anything other than 60 and 50 Hz.

Hello,
i'm trying to reuse an old laptop screen which has a dent at the bottom as a monitor. Setting the resolution from 1280x800 to 1280x720 removes the damaged part but also leaves a black bar at the top. It is a LP133WX2(TL)(A1) LCD screen. Reading from your response to the previous poster it is not possible to move the image to the top with your tool? Or is this just a restriction for TVs? I tried the solution you posted, but maybe i just failed
If not, do you know any other way?

Thanks in advance,
Miri

For digital monitors, you can't control the image position with the timing parameters. That can only be done with CRT monitors. Laptop screens usually don't have scalers, so sometimes they will display lower resolutions aligned to the top with the bottom repeated if you're able to disable GPU scaling. The only other idea I have is to have some kind of program reduce the desktop area, but I don't know of a program that can do that.

PROBLEM WITH NOT PERSISTENT SETTINGS

I've noticed that since I installed Windows 10 2004 some months ago, it "looses" CRU custom settings much more easily than before when they lasted 'till next NVidia driver update... Now my CRU custom res sometimes randomly just disappear and I have to relaunch CRU + restart64.exe. Someone knows why and if there's a "solution" to make custom settings more persistent?

Basically every day I have to reload CRU + Restart64.exe to make my custom res reappear. There was a time when I just set it once and lasted 'till the day I changed video driver. Now for unknown reasons after a night sleep+hibernation the system looses my custom res. If I do sleep or hibernation manually for testing this does not happen and CRU custom res are still there....

EDIT:
Another strange thing I noticed is that I have 2 monitors listed in CRU and in the registry (??), that differ just for "Address" and "ContainerID" values:


EDIT2: from Device Manager (show hidden devices option) I deleted the strange one "1&8713bca&0&UID0". Let's see if this helps...

Hi! first, thank you so much for writing this amazing piece of software!

I'm currently facing an issue here.
CRU is able to create a custom (lower than native) resolution on a new driver version but not on old.

I'm using a Lenovo laptop, it's the IdeaPad G40-45 (quite the old one) with the eGPU variant (I'm using the AMD one).

I first tried CRU on the current latest available driver (as of writing this reply), which is version "AMD Radeon Adrenalin 2020 Edition 20.9.1" and my custom resolution is there! nice!

but my biggest problem with the latest driver is that the performance is extremely poor. I'm curerntly playing this game called NieR: Automata and on my display's native resolution with the new vs old driver, the performance is so much better on the old driver (issued by Lenovo)

the old driver version is "AMD Radeon Crimson ReLive 17.1.1"
BUT! there's also another problem with the old drivver... which is, any custom resolution created by CRU won't show up anyhwere.
To make sure, I even tried a bunch of titles and no custom resolution is there.

I don't want to go back using the new driver but I also really really need the custom resolution...

I did exactly the same process on creating the custom resolution as I did on the new driver but with the old driver, the custom resolution is not showing anywere.

I really hope I could get an answer in here.

for the record, I used to have a custom resolution setting built into the AMD Settings itself, back on 2017-ish.
but now, that option is gone. so, there's no way to create a custom resolution other than using CRU (even through the AMD Additional Settings / Catalyst Control Center).

--- system summary ---
Lenovo G40-45
AMD A8-6410 APU
Radeon R5 M230 2GB
Windows 10 Professional 2004 x64 (fully updated, auto-update always on)
CRU works on driver: AMD Radeon Adrenalin 2020 Edition (20.9.1) and AMD Radeon Adrenalin 2020 Edition (20.4.2 WHQL)
CRU not working on driver: AMD Radeon Crimson ReLive 17.1.1
what I really need: custom resolution (lower than display's native resolution) on old driver "AMD Radeon Crimson ReLive 17.1.1"
CRU version: 1.4.1 (EDIT: updated to 1.4.2 but still the same)

I solved my issue by installing a newer driver than 17.1.1, 17.7.2.
CRU is now working.

UPDATE--
So, I've wasted about 6 hours of my time installing and reinstalling drivers and I found out that 17.2.2 is the best driver for the Lenovo IdeaPad G40-45, probably also for other laptops with a Mobile A series in it.
Sure, you can install the latest driver but you won't have the ability to assign a certain app to use a specific power plan (just like in the AMD Additional Settings / Catalyst Control Center).
Not to mention CRU also works perfectly with 17.7.2...

No way. Once again, after overnight sleep + hibernation, CRU custom res disappeared again
NVidia driver 452.06 WHQL
...and once again Windows re-created the ghost monitor "1&8713bca&0&UID0" (!?)

[heaae]

I've also opened a thread on NVidia forum, as I'm quite sure at this point it's something broken with recent drivers (and/or Windows 10):

That's not normal, and I can't think of what would cause that. I don't think it's an NVIDIA driver bug because it wouldn't delete the EDID override. Even installing a new driver shouldn't delete the EDID override unless you're using DDU to wipe everything first.

Maybe the computer is crashing while hibernating so the settings are reverting to the last booted configuration. Have you tried rebooting instead of running restart64.exe?

The "ghost" monitor is not a problem. That gets created when restart64.exe restarts the graphics driver.
