I'm a lot more into the audio end of HT than video, so I just don't know as much about displays, though I've been doing a lot of research the last several months. Still, there's nothing like first hand experience in your own home. Last week I upgraded my livingroom system with a Vizio 55" M Series, which was $480 on sale. I can't help remembering that seven years ago I spent $420 on a bottom-of-the-line 40" HD Samsung, for comparison, which had been in that room until last summer. This Vizio not only puts that Samsung to shame, it completely blows away the Plasma in my main HT. I mean, there is no comparison, in any way. The Vizio soundly beats it in every... single... way, including black level. Considering that so many people here seem to be only getting about 6-8 years of life from displays, and the incredible performance of this M Series, are high-end monitors even worth it anymore, for most people? My main HT has one significant advantage over the livingroom, since it's completely light controlled. So it never has to compete with daylight. The white levels on the M Series are so high, I'm not sure it would make sense to even move up to a P Series. I'm planning on replacing the plasma in my main HT this year, and figured I'd be spending $1.5K on a 55" OLED, but now I'm thinking I'll get a 65" M Series instead, which I can probably get on sale for $650, or even less on closeout when the new models come out. Then in six or seven years, I can replace it with something even better, if it dies. I'm simply amazed with this Vizio. Plus, it has some very advanced picture controls. There's no broadcast TV guide, which is a big disappointment, since I use antennas for TV, but I can work with that since broadcast TV isn't a big deal for me.
