The best HDTV you can purchase is LED with LCD back lighting. You have to investigate the HDTV to ensure it's a full LCD
backLighting and not just side lighting with baffles to spread the light, sometimes it takes a lot of digging.
The best 3D is through Flicker glasses or one who's lens blink alternately. Mine are battery operated.
would cost a fortune replacing them if I used that option a lot. If you go 3D make sure they are rechargeable or USB power cord.
I purchased a HDTV recently and researched them first to be sure I got the right one. Only to purchase one when Costco dropped them
from $1000 to $300. I thought I made the right choice as well as it's a 600Hz. but a no return purchase.
The key is 24 fps, HDTV's resolution needs to be divisible evenly by 24 or "tricks" have to be used; 600Hz was so I was happy,
3D games were possible only to find out I fell for Panasonic big lie.
It's actually a 60 HZ, a plasma fires 10 times a second, so they multiply that by 60HZ = 600HZ to Panasonic.
My 3D games come in at 30 FPS. Plasma is the best picture but nobody mentioned white is 105 F, during the
summer the HDTV and air conditioner have a stand off. Then there's the burn in and a 100,000 hour life time of the screen.
While it comes across as a lot of time, it's dimming from day one.
My Panasonic TC-P42GT25 also can't be calibrated the contrast breaks at 30%, it's actually too dark to view, I have it on game or vivid mode
(very bright) to see. It's a "smart TV" so I can watch Netflix, youtube, HULU, what have you; but the processor can barely run Netflix - captions aren't an option.
Weary be the purchaser of a HDTV.
