I have a 1080p 50" Samsung plasma I got a few years ago (going on 5). Yesterday plugged in a laptop to it for the first time (no more cable tv for me) via an HDMI cable. And I had the following issues:
1. Full screen on the TV was not filled (black frame around)
2. There is lag when controlling through my wireless mouse, some lag when accessing videos off the HD.
So is it a vid card issue? HDMI cable issue? Or some setting on the TV? The laptop is only a year old, but by no means a junker (i5 processor, not sure about vid card).
When I go into display settings on the computer, I can get the full screen to come up on the TV, but only if I choose non HD as my option.
I guess I should add - have had the computer plugged into a 42" LED the last year and had no issues with it.
