[mythtv-users] Getting a Plasma, Scared of Burn-In

[Marius Schrecker]

This may be a very stupid question, but: What about LCD's? They're far less
sensitive to burn-in, have HDTV definition, and are getting much better
with regard to colour definition, response time and viewing angle. Here
in Norway I can get a 37" Viewpia (8ms, 1200:1 contrast,1366x768)for about
the same price as an equivalent plasma. The very largest LCD's are still
not good enough so if you need 42"+ then I understand.

Cheers

Marius

http://www.itconversations.com/shows/detail562.html is the link to the 
interview. The guy sounded pretty knowledgeable.
