Custom Resolution Utility (CRU)

After adding a 62Hz setting for my external monitor for initial testing, I set the resolution to the new resolution (3200x1800) but couldn't actually set the higher hertz in Windows display settings. The mbp was in clamshell mode the whole time and the internal display was not on, nor was it configured or changed.

Figured it didn't work, and ran reset. However, when I rebooted my computer, a third of my laptop display was heavily pixellated pink noise, and flickered like crazy. The issue didn't seem to affect the external monitor, and graphics benchmarks worked.

One day later, the pink noise went away, but the flickering remained. Now, the flickering is less noticeable, and I'm not sure if it's still there or not.

Did I corrupt the hardware?

What exactly would adding a 62Hz setting (for a 60Hz monitor) in CRU, but not being able to apply it, do to the computer?

Editing the external monitor should not affect the internal display, and any changes shouldn't affect the internal display if it's not on. CRU doesn't change anything in the hardware, so I can't explain what happened. The flicker is not a problem and will go away. Some panels display residual flicker after displaying unusual patterns.
