I convey what my first hand experience shows me, however not sure if you understood the detail of the point I was making? Unfortunately it went right over the head of our dearest Mr. Pot, and as usual got twisted into something else.
To summarise, the discussion was about the suitability of plasma for PC use (at native 1080p res). My point was LCDs/LEDs were better because of the compromise one has to make with a plasma (at least Samsung's models).
To get the sharpest/clearest picture/text, the TV needs to run in 1:1 pixel mapping mode (just like a PC monitor), but on Samsung plasmas (haven't verified on LG, Pana) the Pixel Shift function under Burn Protection gets disabled in 1:1 mode (Picture Size=Screen Fit).
When configured as such, it only takes about 15min on a static image for my E550 to start showing IR on high contrast parts of the screen e.g. PS3's pause icon on black letterbox bar when watching Bluray.
