Panel Screw?

[Olaw]

Can someone tell me what is the purpose of this small Philips head screw on my BOE display panel? Can it be used for adjustment?

Looks to be holding something in place, as screws tend to do, and it looks like it's holding specifically that board in place.

It appears to be a surface mount potentiometer, I don't know what it is adjusting though, my best guess is something like backlight or contrast calibration.

I did some googleing and found pics of similar looking "fine tune" potentiometers.

The panel is way too bright imo, even at 0 brightness setting in windows 11.

Would it end in a catastrophe If i attempted to turn that screw slightly?

Maybe. It depends on what it's for, but I'd imagine it wouldn't destroy your panel if you were to mess with it.
Just be extremely careful, as these potentiometers are fragile.

So worst case scenario i'll brick the panel?

I bought this as a replacement for my Fujitsu Lifebook because the current BOE IPS panel causes eye strain for me, it has PWM backlight + IPS is generally not smooth enough for my eyes, it seems like TN has always been the best for me + this panel has DC dimming. The only drawback is the brightness which is way too high at the lowest setting.

Take a pen and mark the current position. 

Adjust it and see what happens. Probability of hardware/physical damage is small.

Can it be done "live" or would you recommend powering off?

There's a transparent film covering that opening with the pot, which does not show in the photo.
