Large Format TV Options? 118
pipingguy asks: "I'm planning to purchase a large screen TV and I'm leaning toward DLP at this time. After doing research on-line, I'm more confused than before. One thing I don't like about DLP is the relatively limited vertical angle for best picture viewing. LCDs don't seem to be as bad in this regard, but my understanding is that LCD is more expensive per inch. What is the current state-of-the-art for DLP? I'd rather buy a smaller TV with a better picture than one with a larger picture that is less appealing to the eye. And what about the thousands of tiny mirrors in DLP units? If these are mechanically moving parts, isn't that a likely source of failure (so says a Sony rep who wanted to sell me a LCD projection TV). Thanks for any advice/experience you can provide."

Well, when I started comparing DLP and Plasma side-by-side (I was looking at 50" models, BTW), I looked at the detail of both, and even though Plasma theoretically had fewer pixels, the amount of detail was much superior. What I noticed was that DLP pixels are very "fuzzy" (presumably from the projection aspect of DLP), whereas the Plasma was razor sharp from the direct-light aspect.
When you also factor in that Plasma is far brighter with a much better viewing angle, I decided to spend the extra money for the Plasma screen. Of course, only you can decide if the additional quality is worth the extra money, but it worked out that way for me.
I didn't really look that closely at LCD. The Plasma seemed superior enough that if I was going to go for a "sub resolution", then I'd go Plasma.

Now, there are varying degrees of phosphor ignition along the way (the same way a CRT fades). Dissipation begins the moment you turn the set on. After 1000 hours of usage a plasma monitor should measure around 96% of its original brightness, which is barely noticeable to the naked eye. At 15,000 to 20,000 hours the monitor should measure around 80% brightness, or to state is technically, 80% of the original phosphors (gases) are being ignited.

I've always been sensitive to monitor refresh rates.... I see flicker all the time. A regular 60hz refresh bothers me a lot. Gives me a headache. 75hz is the absolute minimum acceptable refresh on a CRT, and 85hz is fine, even under fluorescents. At home, I liked to shoot for 120Hz, because that matched well with nearly everything... it gave me the smoothest possible motion. I imagine that might not work under fluorescents, but I never had a work CRT that could go that fast. (I'm all LCD these days.) (Strangely, I have never been sensitive to the 30hz video refresh rate, and I have no idea why.)
DLP makes me want to claw out my eyes and run shrieking from the room. I can point out exactly which sets are DLP from a hundred feet away. If you are at all sensitive to CRT refresh, you MUST go see DLPs in person, and you absolutely must make sure you have an ironclad return policy. The saturation and color on DLPs is a little better than LCDs, and they tend to be cheaper, but a display that gives you motion sickness is no good, no matter how cheap it is.
If, for some reason, you can't demo a set, then LCD is the safe choice... it will always work, and all your guests will be able to use it comfortably. Plasma is also a good choice, as long as you realize that it does wear out eventually. And, of course, there's always CRT-based units. They don't get as large as the other technologies, but they have amazing image quality and are very cheap, because they're the redheaded stepchild.... people think CRT is automatically inferior, just because it's old tech.
The major downside, at least to the Sony CRTs, is that they are incredibly heavy. You'll need help installing even a small screen. But the colors are rich and vibrant, the blacks are dead black, and the resolution is far better than the CRTs of old.

I bought a Samsung DLP unit, but had to return it due to strobing rainbow effect. It was a really great image, though that was in part because Samsung was doing a very high level of algorithmic sharpening, which can cause halos around some images. But I really couldn't move my eyes across it without seeing the trailing rainbows.
I didn't see this effect in the store at all, but at home the awareness of it really did build up. If you are interested in DLP, you might look at the new units that use high speed LED arrays instead of a high intensity white light bulb to handle the color.. these new ones still flash the colors in sequence, but the sequencing is much faster, and it really and truly is supposed to be below the perceptual threshold for everybody.
I wound up getting a Sony SXRD LCoS set swapped out for the Samsung DLP.. the SXRD was more expensive, but the resolution was higher (true 1920x1280p), with more digital connectors, and better firmware. The SXRD sets are similar to DLP in that they are digital microdisplay projectors, but they use three LCoS color panels instead of a color wheel spinning in front of a micromirror array.

Different people are more or less susceptible to the rainbow effect. Personally, the only time I ever notice it is if I try to play Doom 3 on my Samsung DLP. The combination of a very dark image and fast horizontal movement makes everything crawl with rainbows. Interestingly enough, I haven't noticed it on any other first-person shooter games (Halo 2, Perfect Dark Zero, BF2:MC, Metroid Prime) or any other games (racing, sports, RPGs, etc). I can force myself to see the rainbow effect if I put in a movie, go to a dark scene, and rapidly move my head back and forth. Since that's not my normal viewing style (spastic head movement is not normal), I'm happy with my DLP.
Store displays are set up in such a way as to minimize the rainbow effect (has to do with store lighting, demo material, etc). If you can see it on a set in the store, you're going to constantly see it at home and should stay away from that model. If you're concerned about rainbow effect, find a friend or colleaque with a DLP and see if they'll let you demo it in your home. That's the best way to know if you'll see it or not. Of course, if you're going to demo stuff in-store, you should bring in your own viewing material. When I go TV shopping, which admittedly doesn't happen all that often, I like to carry a couple DVDs (something with action, like Saving Private Ryan, and Avia [ovationmultimedia.com] at the very least). If a store won't let you demo a set with your own material, go somewhere else. Also, if a store won't negotiate on price, go somewhere else. By bringing in internet-based pricing on the 50" Samsung DLP I was looking at (in-store price $2100, online price $1800), I was able to negotiate a free stand ($300 value) while buying the TV at the in-store price (thus essentially paying $1800 for the TV, without having to pay for shipping).
Newer equipment is always better than older equipment, even if you still go with a traditional color wheel and bulb. for example, from the HL-P series to the HL-R, Samsung added more color sections to the wheel and made it spin faster, thus significantly reducing the possibility of rainbow effect for most people. The morale of the story is to know what model you want to buy (usually the newest, not last year's model), and make sure that's the one you're actually buying (big box stores like Best Buy are notorious for selling sets from two model years ago at current model prices).
I assume you mean 1920x1080p, not 1280p. But anyway, I'm not sure now is the right time to go 1080p. The price of 1080p sets is still significantly higher than a 720p set, and you're going to have a hard time finding 1080p sources (assuming you buy a set that can actually accept 1080p signals ...).

I skipped plasma due to the cost and the fact that I felt the picture had the most pronounced screen door effect of any HDTV technology. I liked DLP, but since most HDTVs use a single chip DLP solution there can be a noticable shimmering rainbow effect on the edges of objects during movement as a color wheel must be used to display the full range of colors. I noticed it on several models and decided to skip DLP for the time being and noted that DLP sets will also require costly replacement of their high brightness lamps, just like LCD. Three chip DLP sets, one DLP chip for each of the primary colors, red, gree and blue, would eliminate the rainbow edge effect, but don't expect anything like that for less than $30,000. At some point three chip DLP will be standard, but it will be a while. I really liked the CRT rear projection sets I looked at and they were several hundred dollars less than LCD, plasma or DLP, but everyone I talked to that had one found that picture convergence was a problem (more so than SD rear projection TVs) and that static picture burn-in could be an issue (although I am told that doesn't happen anymore). Also, CRT rear projection TVs are heavier and bulkier than LCD or DLP.
I don't know about the overall reliability of DLP, but I do have a DLP projector that is a few years old and haven't noticed any loss of picture quality or missing pixels. If the quality of the SD picture wasn't as good as it was on the Sony, I would have bought a DLP TV, but nothing I saw with the DLP technology matched the quality of the SD picture from Sony. I don't think that's a limitation of the DLP technology itself so much as Sony finding the best method to display an SD quality picture on a HDTV.

Second, I went to stores and evaluated different TVs which use different technologies. You can read AVSforum and all of the various professional magazines about this stuff, and they will measure black levels and white levels and everything else, but really those evaluations are nearly uselless. Those sorts of technical reviews myopically focus on individual aspects of the picture and their ratings rarely consider the overall image quality. The quality of a TV picture is really subjective, so it should be evaluated that way in terms of your buying decision. It's not always easy to do this in stores, but I decided that if I was going to buy a $1500 - $3000 tv set, the retailer was either going to help me do that, or not get my business. So I brought DVDs with me of a couple of movies that I am well familiar with and which had characteristics that would help me decide. These included:
Spider Man -- Action movie with very vivid colors and tons of sweeping action, to verify color and motion reproduction.
Sin City -- Probably the most black ever in any movie, good for, obviously, measuring black levels.
The Fellowship of the Rings -- an excellent, very sharp DVD transfer, just for image quality and again because I've seen it so many times.
(Yes, I realize that DVDs will display at 480p on these sets, and HD is 720p or 1080i, but the majority of programming I'll watch on this TV will be DVDs, and DVDs are the only media I can really control. Besides, the store always has Discovery-HD or that awful Charlotte Church video fed across all their HD sets, so it's easy to compare among the HD feeds.)
Then I went to the stores. I looked at rear-projection LCD and DLP first, since they had some compelling advangages -- similarly priced and lightweight. As it turns out, neither of these was that great. Both of those suffer from poor black levels (black looks gray) and restricted viewing angles (if you're not pretty close to perpendicular to the screen it will look dim). In addition, DLP sets have a sort of shimmering optical effect that I noticed and just didn't like. The best of the rear-projection sets was the Sony KDFE42A10 LCD RP -- it definitely had the blackest blacks and the best color reproduction -- but even so, I wasn't completetely satisfied watching movies like Sin City on it, and I still hated the picture degradation when sitting more than 45 degrees off center from it. Still, it was just about good enough. But I needed to look at plasmas.
So I went and looked at plasmas, and it was just absolutely night and day. I had spent a good deal of time looking at the rear projection sets, and each usually was better than the others in one aspect. But the plasma sets were almost all universally better than the RP sets. Colors were more vivid, blacks were blacker, the picture was smoother despite the physically lower resolution [1], and there were absolutely no shimmering effects. They weren't all free of artifacts, to be sure: some of them seemed to have slower response times, and got jaggies or pixelation in fast-moving scenes in Spider Man or when the Discovery-HD feed showed waterfalls for example. The best of the pack overall turned out to be the Panasonic TH-42PX50U. It was about $8000 higher than the Sony RP-LCD, but its picture quality just couldn't be denied, and that's what I wound up purchasing.
And about plasma... I read all about burn-in and screen lifetime, and decided neither was a big issue. I was careful to keep

Actually, that's an artifact of MPEG encoding. I watch a lot of nature shows and can't tell you how many times I've seen that in shots of running/rippling water, even on my vintage-2000 56" SDTV. On smaller or blurrier screens you don't tend to notice it as much, but on any sort of large or higher-quality display, it's painfully obvious. So if you feed an SD signal to a very high quality plasma dis

#1: If you saw LCD's with better black levels than DLP, then either the DLP model sucked or more likely the STORE set the brightness levels WAY up to attract attention to the TV's.
#2: Plasmas. The biggest problem I have with these is the concern of burn-in. Over at AVSforums there's lots of threads dealing with this, but the jist of it is that you have to be careful for the first 1000 hours or so at LEAST. The biggest issue is watching ANYTHING that puts black bars on the
How to frame your decision (Score:3, Insightful)
1. Should I buy a DLP, LCD, or DILA? These competing display technologies all have their strengths and weaknesses. In an effort to be objective, the *general* consensus for DLP units are that they offer higher contrast and a sharper image, but at the cost of the "rainbow effect". LCD units offer more vivid, saturated color, but at the expense of higher black levels. DILA units, called SXRD when under the Sony brand, tend to share the strengths and weaknesses of LCD's. Now for my subjective opinion, I prefer an LCD because I am quite happy with the rich image, and the rainbows of DLP color wheels render them unwatchable for me. Even on DLP's with a high-speed color wheel, although the alternating red, green, and blue components of the image are not consciously visible, I found that I get a headache after watching it for 90 minutes or so. So I strongly prefer LCD's to DLP's, although this is a question on the order of Ford vs. Chevy, domestic vs. imported, Windows vs. Mac, Ginger vs. Mary Ann...
2. Should I get a flat-screen, rear projection, or front projection unit? This is another important question that you didn't explicitly consider in your post, but it's essential when you want a large-format screen. A flat-screen, which may include LCD's and plasmas, may offer the most vibrant and saturated image, but at a higher cost per inch of screen real estate than other options. Rear projection TV's pass light through an LCD, DLP, or DILA filter to form an image on the back side of a (usually) black screen. Front projection TV's can create an image of arbitrary size, depending on the projection distance, with a tradeoff between image size and quality. The Achilles heel of front projectors is ambient light - the image gets washed out when it must compete with other light sources. Projection units tend to give you more image for your money than flat screens.
After extensive research, I selected a Sanyo PLV-Z4 for my TV. It is an LCD front projector with good contrast with future-compatible features (particularly HDMI with HDCP) and an attractive price. I painted a neutral grey screen using Screen Goo. I found that the image is sparkling when the room is completely light controlled, with deep blacks and rich color. I use a screen diagonal of 84", even though the unit could be enlarged to 100" or so, because I prefer image quality over size. My living room is flooded with ambient light, so I convinced myself that I should be doing other things during daylight hours, like working or being active outside. Ambient light problem solved. 8)
What works for me may not necessarily be the best thing for you, but I've been quite happy with it. Good luck.

Best way to demo the rainbow effect is to get a small patch of light colour surrounded by a lot of dark. Then you can look rapidly left to right and as your eyes move you'll get the different R,G and B parts of that light spot. The effects are similar to mouse trails.
