re-reading your first post, you say you hook up the laptop to your system.

Now TV's have built in Wifi and Netflix or other streaming source.

So yes you have HD signal.........its just that your present TV sucks at delivering it to you.

Go to Best Buy, and go do your own viewing, I personally like more a satin finish screen than glossy glass that shows way too many reflections.

TV's are just a price point.

and a person choice

YMMV
