I plugged my Laptop into my TV (42” Sharp 1080i) and I received this: -
As you can see the taskbar and the left edge aren’t visible, after playing around with screen resolution and not getting anywhere I decided to take a look at my remote. I found an option which allowed me to put the TV into under scan which resolved this issue.
