The W802 is for sure using lg's ips panel (just googled it).
I couldn't find any panel info for the R550 though.
IPS will have worse black levels than VA.
If the R550 is VA then it might just be a better choice than the W802.
Side note.........In the UK sony is offering a 40'' and 46'' version of the W900.
People in US get stuck with crappy frame dimming for a 46'' set.
While people in the UK get nice local dimming for a 46'' set.Edited by CalebLevArn - 4/18/13 at 3:07pm
