I was pretty much sold on the Panasonic TX-P42G30B (or maybe the ST30) until I found out that it doesn't properly support PC RGB 4:4:4 (I use my PC for all my media via MediaPortal and also for gaming). I'm also rather put off by the shifting gamma problem (or “enhanced brightness perception” feature as Panasonic apparently describe it!)
So are there any decent Plasmas for around £499-550 that do properly support PC RGB?
