Dear developers
I have a Samsung 40’ HDMI TV, which has wrong EDID.
The actaul size of this TV is 40’ (88cm*49cm), but in EDID the size is 49’ (106*63cm)
Thus makes image size is larger than screen, both in console and desktop.
That's not how EDID works in Linux. It's only used to compute the DPI of the screen, not to scale the image. If the image on the TV looks like it extends off the edge of the TV you need to find the "overscan" setting in your TV and turn it off.
