Viewsonic PX747-4K projector not full screen


Novice Member
I have recently purchased o Viewsonic 4K projector to use with my Apple TV 4k. The issue is that no matter what, there is still a significantly wide (about 10cm/4" - depending on the distance of the projector) border around the whole screen (see pics below).

Ive tried multiple input devices (both HDMI and VGA) and adjusting the keystone and overscan settings but nothing made the projector go fullscreen.

Any ideas how to solve this? Or is the border supposed to be there?

This is normal for 4K DLP projector. Benq W2700/HT3550 have a smaller border
3LCD don't have this "issus" like Epson TW7100/HC3800
