After running restart64, the F8 button takes you to recovery mode in case you get a black screen. Otherwise you could connect an external monitor and remove the changes from there.

If that's not an option, you could try to boot Windows into safe mode, which would also allow you to remove the changes set in CRU.

Just press F8 after turning on the laptop?

Well, F8 right after you run restart64.exe. I'm assuming that's not an option anymore as you've tried rebooting the laptop, etc.

Booting Windows into safe mode is tricky, here's an official guide. Your best bet is trying to boot the laptop and shutting it down while windows is booting.

I can’t get into safe mode, I tried different methods, nothing happens at all, just a black screen

Quoting ToastyX here

Quote: Before making any changes, familiarize yourself with getting into safe mode using a recovery drive in case you can't see the screen. If you don't have a recovery drive, press and hold the power button to shut off the computer while Windows is booting. Doing this twice should give you recovery options that you can use to get into safe mode: Troubleshoot > Advanced options > Startup Settings > Restart

So your best bet is this to get into safe mode. The Windows logo is visible during boot, I assume.

Hi @ToastyX. Thanks for years of amazing fixes via CRU... indispensable!

I always use CRU to remove the 4096x2106 resolution from my TV's, as I find it can cause issues when launching some games for the first time on my PC. I've just upgraded for a Samsung S95B QDOLED to a Samsung S95D QDOLED and I am finding that my regular CRU fix methodology is not working. Games are still showing the 4096 resolution, as is NVCP?? Steps followed are editing the CTA-861 Extensions Block as follows:

1 Remove all 4096x2160 resolutions from 'TV RESOLUTIONS' (there were 6x)
2. Remove all 4096x2160 resolutions from 'HDMI SUPPORT' (there was 1x)

Looking at the how to (and some earlier posts here), there is reference to removing the resolution from the '4.2.0' Block also. Whilst I've never had to do this before, happy to do so, however the only block I have with a similar naming convention is '4.2.0 CAPABILITY MAP', but that is greyed out?

Have tried multiple reboots, restarts and resets, but that pesky resolution remains available in Windows 11 for some reason!?

Have added a screenshot below... would appreciate any advice. Thanks

Did you change your screen's resolution to 1920x1440? It will not work due to the resolution being higher. It will only work the other way around (laptop resolution 1920x1440 and custom one 1366x768).

Well, yes, I made a mistake, I just didn’t know how to fix the black screen?

Come on, man. Why didn't you read the first post before using the software? Literally everything you talked about is there. You need to boot Windows in safe mode and run reset-all.exe.

• Run restart.exe to restart the graphics driver.
  • If the display does not return after 15 seconds, press F8 for recovery mode. This will temporarily unload all the EDID overrides without deleting them. Restart the driver again to reload any changes.

• CRU adds monitor resolutions, not scaled resolutions. Lower resolutions can be scaled up to the native resolution by enabling GPU scaling in the graphics driver's control panel, but higher resolutions won't be scaled down by the GPU. Higher resolutions will only work if the monitor can handle them.
• Laptop displays usually don't have scalers and can't display non-native resolutions without GPU scaling. To add other refresh rates, add the refresh rate at the native resolution. The graphics driver will automatically add the refresh rate to lower scaled resolutions.

Is there another extension block? I need to see everything. Run this and post the test.txt here: https://www.monitortests.com/EDID-test.zip
