I just got my chromebook yesterday and have been trying to hook it up to my tv via hdmi. For some reason when I plug it in, the screen on my chromebook turns into a square, leaving a few inches on the right side unused, and the image on the tv appears stretched.... I tried acer tech support and they tried to make me buy a service plan. Not gonna do that. Any ideas for why it is doing this? Is there a settings menu for hdmi connections? I haven't had any luck finding anything so far.
