In Reply to: I have a 50" Sony XBR LCD Projection TV and the picture is Wonderful, posted by Paul in Sterling on November 11, 2003 at 19:35:16:
I like the XBR LCD also. I particularly like the built-in scalers in Sony sets.I should have elaborated that the magenta cast (look at whites) I saw was related to a fairly high color temperature setting even in the normal and movie modes. This really is a matter of preference. I like a warmer picture (lower color temperature), but in any case, the gray scale calibration you alluded to would bring the set more in line with NTSC standards.
I suggested looking at dark scenes to bring out the worst to determine if the prospective purchaser can live with its primary limitation. As for the rainbow effect on DLPs, I see them once in a while, but it doesn't really bother me. I would suggest that a buyer determine for himself whether the rainbows are objectionable. The effect is most often seen with bright white objects against a darker background. Some viewers report eye strain and headaches from viewing DLP sets; if possible, an extended review session would be advisable.
One other common problem with rear projection fixed pixel sets such as DLP and LCD sets is a sparkling quality to large white areas caused by the use of a lenticular screen (tiny lens elements in the front screen used to focus the light into a tighter beam). If that bothers you (it bothers me more than the rainbows from DLP sets), look for a set that has a diffusion screen. The tradeoff is that diffusion screen sets do not look as bright when sitting on axis with the set.
I know it is quite a bit beyond the price range specified, but I saw a very good picture from a Toshiba 57" LCOS set. This uses a different kind of LCD element. Instead of blocking or transmitting light to create a picture, it either blocks or reflects light. The Toshiba set had incredible detail, natural colors and a decent (not great) black level. This technology may be a serious contender in a few years.
Follow Ups:
At least for the time being. Too many faulty sets from what I heard.Toshiba LCoS: to be continued... maybe.
Did they pull the cheaper set they were showing at CEDIA this year? I know the prior, $9,000 version had a number of problems. I guess the track record for LCOS sets coming to market is pretty bad (RCA also failed). Somehow, I doubt that the $20,000 version by Mitsubishi will be leading they way in the market.Perhaps Sony can make a go of it. I saw their SXRD Qualia front projector at CEDIA. It looked very good. The demo included a lot of dark scenes which had amazing shadow detail. I am hoping their LCOS technology makes it to a RPTV in the near future.
All I read in the RPTV forum on AVS is that Toshiba pulled their LCoS stuff and there is no word if or when it will return. In the late Spring and early Summer, all I saw were posts from owners with convergence, scaler and various other display problems.When you put out a $9,000 display and the scaler from a $200 DVD player (Sigma Designs in the Bravo D1) gives a better picture compared to the one that the display scales, you gots problems!
.
I hope to see a solid implementation in my lifetime.I can't hack the blacks and shadow detail on either DLP or LCD yet - and I don't even see rainbows.
Interesting link.
