This is a 720p HDTV so while I could bet you could feed it 1080 content the truth is that when we play video games the long standing lesson is to not make the host computer work too hard and you get more frames per second, less lag, etc.
Hi,
My 42px77u has a resolution of 1024x768 but can accept 1080p sources.
Since this resolution is far from what my TV displays, should I leave the 1080p check blank?
