    After paying an arm and a leg for a Plasma screen, I can honestly say that it sucks... worst dollar to value ratio ever. The resolution is okay (I'm not talking about the gateway/circuit city peice of shit that has EDTV resolution)... the picture isn't anywhere near as good as you can get with LCD or DLP...

      Plasma still exists because it has one advantage over LCD/DLP in the price/performance war: Bigger direct-view screens that can be easily mounted on a wall. Rear-projection LCD/DLP units give better value in terms of screen area but they take up more space. In other words, it's a style-over-substance issue.

          After Viewing All other technologies (at the time), I purchased two televisions - One A CRT Projection Sony (HDTV) 46" and a Panasonic Plasma (EDTV) 42" (both highly recommended on almost every method of research I performed). Hands down, the Panasonic kicks the Sony's ass, I have NEVER seen a better picture (I've only been to best buy, circuit city and The Big Screen Store, and there ilk). The real word black level performance (eye candy view) is just as good. Matter of fact, I bought the plasma just because the room that it's in was so small. I planned on using the Sony most of the time, especially for movies. The plasma is so much better, the CRT justs sits there most of the time.

        I guess I'm ahead of the curve -- I bought a Sharp XV-H37U projector nearly eight years ago. It was one of the first three-panel LCD projectors that had decent picture quality.

        I too was worried about bulb life... since they cost $400-$500 each. I was doubly worried regarding the lifetime since I bought a floor model that had an unkown history to it. (Back then the projector was a $6000 investment, buying a floor model saved nearly $2000)

        However, nearly eight years later I'm still on the original bulb, with no perceptible degredation of brightness. At this point, I'm hoping that the bulb dies so I can justify a modern projector! So far, it's refusing.

        Now the caveats: I'm my home theater I have both the projector and a traditional CRT-based TV. I use the TV for all normal TV watching and only use the projector for nighttime movies and special TV shows. Once the projector is on, it averages 4-6 hours of use, but I'm very careful not to needlessly power cycle it.

        I believe that with some common sense, the bulb-life issue doesn't really exist.

    The article was slashdotted, heres my personal guide:

    CRT - Still probably capable of the best picture for now (especially at the high end, think G90). Requires much more maintenance than digital technlogies (convergence, etc.). Essentially infinite on/off contrast, not quite as good ANSI contrast. No screendoor. High end guns capable of fully resolving 1080p.

    DLP - Best contrast numbers of the digital technologies. Consumer units limited to 720p for now. Screendoor is pretty limited. Some people may see rainbows on one chip devices due to color wheel (pretty limited on new HD2+ machines). Most machines not terribly bright when compared to LCD. Limited to projection devices.

    LCD - Poor contrast, very hight black level. Most screendoor of the digitals. Can be in projection or panel configurations. Considerably less expensive than other digital techs. Scales to higher resolutions than DLP for now.

    LCOS - Least screendoor of digital technologies. Often appears "smoothest" or most like a CRT to people. Contrast numbers not up to DLP's standards. Not a large number of LCOS unites on the market for now, but looks like more will be coming soon. Many see it as the ultimate sucessor to CRT rear-projection.

    The newer technologies are nice in that they are thin and all, which is especially good for monitors. But, they do still have their drawbacks. LCDs don't display black as well as a CRT, making watching movies with dimly lit scenes annoying. LCDs have a very clear picture, but lose some of that sharpness if not run at native resolution or another that divides evenly into it (interpolating from one resoution to another causes slight bluriness or jaggedness of the pixels). Also, I have doubts as to whether the time between failures on LCD backlights is as good as CRT picture tubes.

    Plasma is kinda neat, but has a reputation for burn-in and slowly losing brightness over time. If I was to buy a multi-thousand dollar TV, I'd want it to work for 8-10 years until the next big thing comes along.

    For now, I'm still a CRT user. 35" Sony Trinitron for TV watching, 21" ViewSonic professional series for the PC. Keeping an eye on the new technologies but they're not quite "there" yet as far as I'm concerned.

      Yes, burn-in is a potential problem with plasma, but it's also a problem with CRT and any other technology that uses phosphors. Modern plasma displays have a half-life approaching 60,000 hours. Even if you leave it on 24/7, you've almost got your 8-10 years. Besides, after 60k hours, the brightn

    When I bought my last system, I could have bought two decient 17" CRT'S for the cost of 1 19" LCD display. So I am now sitting in front of two 17" CRT's and I have twice as much desktop space.

      Umm, a 19" LCD is equivalent to a 20-21" CRT. Remember, CRTs are measured by the total size of the monitor case, while LCDs are measured by their actual screen size. I prefer the crispness of LCDs, and you mention having more desktop space with CRT. I have more physical desktop space, and with a 15ms response time, my LCD is more than adequate for my gaming needs. $250 for a 15" LCD is more than worth it to me (I got it almost a year ago). Now when I use a CRT, I notice the horrible flicker from the monitor

  • My 42" HDTV-ready 16x9 projection TV cost $1300 over a year ago. Comparable size plasma is a minimum of $3000! Plasma, LCD, and DLP restrict you to a single optimum resolution, whereas CRTs (and thus projection TVs) are infinitely variable. Probably your best best is to stick with a CRT until all broadcasts are done at a specific HDTV resolution, then buy a DLP projector that handles that resolution. If you really think it's worth paying twice as much for something because it's only 4" deep instead of 24" d
  • One aspect of display technology that I don't hear discussed often is the need for multiple resolutions. As a software developer, and a GUI developer at that, it is important to me to be able to quickly view my work cleanly in all standard resolutions to see how it will appear to the end user. Fixed-element displays such as plasma and liquid crystal are simply useless for this: yes, a good driver will attempt to interpolate but this produces garbage from a developer's standpoint.

      I've been developing on LCDs for years now. When you adjust the resolution, set the monitor to just center it rather than trying to scale to fill the screen. That way, your 1600x1200 monitor just has a large black area surrounding the 640x480 test screen. Way simple.

    As LCD monitors get bigger, the viewing angle problem gets more severe. I just got a ViewSonic 19" LCD with supposedly good "viewing angle" specs. The problem is that you normally sit within 2 feet of your monitor. At this distance, your eyes view the top of the screen at a very different angle than the bottom of the screen. With a large LCD like this, there is absolutely no way to view the screen without severe differences in color... the monitor is just too big and you are sitting too close to it. I find myself constantly adjusting the monitor, or raising and lowering my head to try and read things.

    This is a problem I never noticed on my smaller (laptop) LCDs, simply because the monitor is much smaller.

    Obviously this wouldn't be a problem for an LCD in your living room, where you view it from quite a distance. But large LCD monitors are a problem. (At least mine is!)

    The organic-based displays come out. Flexible, brighter than LCD, superior to plasma (no burn-in).


    OK, OK, I'll wait until the organic displays are around for a while and their price reaches non-astronomical levels. That should be in about 7-8+ years from now assuming a soonish release.

      Poor pigment life has killed them commercially until a new generation of longer life ones can be developed (if at all). While people complain about plasma the avg life of older units is 30K hours and the newer generation is 60K, thats a LONG time. Lamp based units have fairly expensive bulbs to replace but at least you aren't scrapping the whole tv.

    I originally was all psyched over LCOS. But with the problems they've had with it and the price I'm now looking toward buying a DLP based tv later this year. Toshiba is dropping its LCOS line (has discontinued it already) and will be releasing a ton of DLP based models in a few months. Initially with the 6 panel color wheel, but then the 7 panel one.

    I would never get an LCD tv. The black level is trash.

    If you've got the space stick with CRT, but if you want something skinnier go with DLP. Should be interesting to see what Intel does later this year with LCOS but I wouldn't touch it just yet.
