Please help! I can't get my Acer V3-111 laptop to display a full screen imagine using a HDMI cable onto a Samsung tv. It use to work with no problems on a different tv but when I tried it on this tv I get a large black border all around the edge reducing the displayed image significantly. I have looked at many fix suggestions and the one that seems to work for everyone else is to re-scale the image but that option does not appear and I don't know why
