1080p display of 720p signal

I am about to move to another house, and in the process will be buying either a 50" plasma or 52" LCD panel for may main tv watching. I currently have a 40" Sony LCD with native resolution of 720p, and subscribe to DirecTV with all the HD offerings, making use of the HR20 DVR.

The largest component of my TV viewing is sports programming (particularly football and baseball). I am wondering how programming that originates in a 720p HD signal displays on a 1080p set. In other words, does the picture appear streatched, or otherwise less dense on a 1080p set once the picture is scaled to the native res of the set? I ask because I believe ESPN and ABC's HD signals originate in 720p, and I am sure there are others. Thanks for any input.

720p (1280x720) scales to 1080p (1920x1080) very well. Partly because there is a fairly even multiplier of 1.5 both directions. I doubt if you could tell the difference between viewing the same 720p program on a 720p set and a 1080p set. However when viewing 1080i programs there will be better detail, assuming the 1080p set has a proper deinterlacer.

When I go back to the new house for the inspection this Thursday, I plan on getting a better idea of the amount of ambient light in the room where I will be doing most of my viewing to help decide between LCD and Plasma. The room has a large bank of south-facing windows on one side, but there is an arboretum filtering the light into the room over the patio outside the windows. 50" plasma or 52" LCD is the largest screen that will fit in the room without undergoing some more than major modifications to the space that currently houses a Mitsubishi rear screen projection LCD (it's a 60" 4x3 box and has to go).

My research has pointed me toward the Panasonic TH-50PZ85U for plasma or the Samsung LN52A650 in the case I choose to go LCD. I omitted the fact that I also have an XBox 360 and PS3 running through a Marantz HDMI home theater receiver as well. The XBox is for Forza Motorsport 2 and the PS3 for Gran Turismo 5 as well as Blu Ray movies.

Thanks for the input.
