Just got my 2808ci from 6thave, and hooked up my Polaroid DVD/DVR and Wii with component cables (480p). Ran a hdmi cable to my Panny 42PX60U, and played with all the upconverting settings (auto, 480p, 720p, 1080i, 1080p, off). Every setting looked worse (each to a varying degree, with 480p setting being the best) than if I just ran the component cables straight to my TV. The TV identified the correct input resolution each time though. Even turning off the upscaling resulted in a poorer picture on screen (ie, it's not passing the signal through cleanly). The picture was never trashy, but there was just a enough loss of crispness and smoothness to know something was missing (I swapped the cables back and forth to verify).
Perhaps the Panny's have really good internal upconversion already? Anyone else have this TV? Do i need to re-adjust color/contrast settings with the 2808ci feeding in the signal?
One thing I also noticed, is that the white text for the 2808ci's menu will change in crispness based on the upscaling setting, even though it's just displaying a black screen with white letters, and shouldn't be dependent on any upscaling, right? In each setting, there is some amount of fringing around the menu's "finger" (480p being the best again). Could it be my $8 generic 12' hdmi cable I'm using? Isn't it just digital though, so shouldn't matter? Anyone else notice a difference in the menu text/finger based on scaling setting?
I'll keep my DVD and Wii connected straight to the TV. Looks incredibly brilliant that way as it always has.
