I've thought about this before, but a lot more recently since we got a 1080p Samsung LCD the other month and a 1080p Mitsubishi this week. To you all that use a satellite or cable box, what resolutions do you set it to output? I have had a Toshiba HD rear projection for years that was only capable of 1080i and 480p (actually it upconverted 480p to 540p). So I just had the DirecTV receiver output at 1080i for everything. I know everyone is into "upconversion", but until upscaling DVD players came along I always thought messing with a signal was a bad thing. Besides, most all early HD sets upscaled signals to another resolution any way. I have the receiver set to native and all resolutions checked. So whatever the channel is, it's going to output at the channel's resolution. Then let the TV decide what to do with it. Doesn't the 1080p sets scale everything to 1080p? So if I only chose 720p and 1080i, then when I watch a 480i channel it's going to scale it to 720p and then the TV is going to scale it again to 1080p? Isn't that a lot of scaling and/or processing going on?
Just wondering what you guys do?
