Good HDTV viewing on large, wide screens that tend to reflect and insert glare into the equation, means proper light control. No way around it, even with LCD/LED if the HDTV is truly situated in a fashion that annoys the viewers .
I just started looking for my first HDTV and thought I had one picked out (Panasonic TC-P46ST30) based on revies sites. Plasmas sounded like the best PQ for the price compared to LCD/LEDs. Until I saw it in the store. Of course the plasmas are mostly mixed in with super bright LEDs, but it was hard to think anything other than how dim it looked. I was told Samsung plasmas were not as dark as the Pannies, and reviews were great on the Samsung PN51D6500, but read a LOT of stories of unaddressed brightness "popping", something the Panasonics had a problem with, but were fixed. I was also looking at LG, which I was told had the best brightness for a plasma, but they seem to be ignored by a lot of the bigger review sites, and Best Buy (the only decent size store in town anymore) doesn't stock or display them (in plasma).
To those of you who have a 2011 Plasma in the sub-$1000 price range, have you been happy with the brightness level? Our viewing is around 25% daylight, and can curtain the windows to keep direct sun off the screen, but don't want to have to black the room out to enjoy the TV during Daylight Savings Time (we like to catch the sunsets through the west facing windows while we view). Our 32" Toshiba CRT TV didn't handle the glare very well, but I'm mostly concerned with if plasma's brightness will overcome ambient light.
