You can do 1080p 24 with any of the recent Mits RPTV's out right now. It's been a feature with them going on at least the last 2-3 years or so.
The white dot problem seems to no longer be an issue. Not sure when the last years model had that happen. Maybe 4-5 years ago or so? It may be to early to know 100% for sure yet though as that's a problem that rears it's ugly head as time goes on.
Maybe someone else more knowledgable than I on that topic can give you more insight.
I have a 4 year old WD-65736 that still runs like a champ. I had to change the bulb on it finally after about 3.5 years of use. The picture and everything about it is as good as when I first bought it.
If you like DLP's you're gonna love how good the PQ has gotten on em the last couple of years or so. I have last years model, the WD-73640, and the PQ on it to me and everyone else who has seen it, has said that is it a HUGE step up over my 4 year old WD-65736. To me it's like a night and day difference.
I'd love to see if they've been able to improve the PQ on this years models. I had always wished I'd gone with an 82" screen. I think in about 6 months or so I might sell my WD-73640 and move on up to an 82" or a 92".
Also if I were you I would just buy this years model. The 42 line up. Also for the amount LG gave you, you could be able to possibly almost get an 82" if you wanted to as well. I haven't checked recent prices but an 82" could be had for somewhere in the $1600-$2000 range. Depending on when you buy it of course.
Alot of people last year were able to score a WD-73640 for only $740 shipped last year!!!!!!!!
I was 1 of those individuals. It was an online sale that lasted only a few hours because the TV's sold out so quickly.
