Custom Resolution Utility (CRU)

I'm wondering if I just destroyed my laptop monitor.

I have a Lenovo Legion gaming laptop with an Intel GPU and Nvidia RTX2080 GPU that G-sync's to my 1920x1080p laptop screen and only runs at 144Hz.

It's 2023, but I recently bought Lego Indiana Jones (from 2008) on Steam and discovered that it throws an error and won't run on anything higher than 60Hz. There's no way to change the refresh rate in Windows 10 or with Nvidia's control panel, so I was directed to your CRU. I opened it, and clicked "add" under Detailed Resolutions. A new profile popped up and was already set at 1920x1080/60Hz, so I added it and used your restart.exe.

The game now loaded successfully, but it was super dark and there were ghosting issues like crazy. All the underlying screens seemed to appear on top of the game (for example, the title screen was still visible as a ghost image once the game started). I thought it was an issue with the game, so I tried to adjust some settings to brighten the screen, etc. I tried many paths, but much to my horror, upon switching back to 144Hz, my regular Windows desktop retained the ghost images. Even after restarting, my black POST screen showed my desktop icons in a ghost image.

Have I ruined my laptop screen? I reverted everything, but the ghosting is still there.

Leave it on for a few hours at 144 Hz and it should fade away. Panels that don't support 60 Hz are not common, but I'm seeing it more in certain gaming laptops. If it can't handle a standard 1920x1080 @ 60 Hz without freaking out like this, I would consider that a poorly-designed panel. To add a working 60 Hz, you need to copy/paste the 144 Hz timing parameters, and then change the timing to the vertical total calculator, and change the refresh rate to 60 Hz without changing the pixel clock. Since the panel supports G-SYNC, this should work in theory because it increases the blanking while keeping the pixel clock the same, similar to how G-SYNC works.
