How does it do connected to TV antenna or cabul or sat converter box? Does a 
TV box let you select 1080p without any sign of any error message or distortions?

Locally (e.g. easy)? If so, do it. Retailers and manufacturers need to know 
when they are letting dysfunction out the door.

Google your model number and see if there are complaints, recall, or other 
clues to trouble.

Knowing what's there doesn't help a lot without seeing Xorg.0.log from using it.

AFAIK, UseEdidDpi is only for proprietary NVidia drivers, and official Xorg 
releases have no option to specify DPI directly, while DisplaySize should 
work almost without exception.
