all 4K TVs as of today are LCD, and LCD sucks, 4K doesn't make it magically better
I would wait until 4K content is more widely available and OLED TVs get into the 4K range; if you are buying a TV the only good options IMO are plasma or OLED, stay away from LCD
just ask w3bb0, he loves my TV and hangs up at my place all the time just for that :)
I've only been at yours once since you got the new TV and ...you kicked me out halfway through watching Predator 2 because you wanted to see your girlfriend, douchebag.
Anyway, yes, plasma TVs look better than LCDs, but OLEDs look better too - I'm just waiting for large (60-70 inch) flat, not curved, OLED screens to come out.
Still, I'm happy with my LG plasma TV and am not looking to upgrade for a while yet. If I do get a new TV then it won't be until OLED fits my needs and I'll keep this plasma in a bedroom or something.
