On my family tv back home, it works fine. I plug everything in and it just works. When I plug it into my tv at uni however, I get no picture on my tv.
My tv is only 720p, whereas the main one back home is 1080p. Could that make a difference? I've tried several different resolutions on my laptop.
Problem is, the setting it remembers is to just display on other screen (as apposed to displaying on both), meaning I can't access settings whilst its plugged in as it only 'displays' on my tv. Any ideas?
