I plugged my laptop into my TV via HDMI, both displays are 1920x1080 and I have it set to Mirror my laptops display onto the TV.
It does so, except I have a black border around the display on the TV, as if my laptop is only taking up 90% of the screen horizontally and vertically or so.
Tried messing around with the ATI Catalyst Control Center but couldn't find any settings... No idea what could be causing this? I've found similar queries where the aspect ratio of the secondary display is off, but that's not quite what's happening here...
Thanks, I messed around with my TV settings a bunch and got it to be almost 100% used, probably 99.9% of it is so at a good viewing distance the tiny border was unnoticable. I'll look into this more later when I'm not at work, though! – sab669 – 2014-08-18T10:58:09.983
