My computer monitor's max screen resolution is 1440 by 900. I don't even think that qualifies as HD. But does VLC play HD? What about InterActual player? Does that play in HD?

That screen resolution is HD, it can do 720P. VLC can do HD, just as long as you have the computer to handle it, but either way, you computer is going to scale the video to your screens resolution, so if you try to play 1080P on it, its gonna scale it to 1440x900

And dont use InterActual Player, period
