CNET's HDTV World
xerid writes "CNET.com has a collection of articles and videos on HDTV and related technologies. It looks like a good starting point for anyone interested in buying an HDTV in the near future. They also include Editors' Top HDTV picks. For top flat-panel HDTV plasma: Panasonic TH-42PHD7UY." From their Ultimate TV Buying Guide: "Since the first HDTVs appeared in 1998, high-definition television has been on the mind of every TV buyer. The big question is whether now is the time to pay a few hundred to a few thousand dollars more and take the plunge on an HDTV set. We can't answer that question for you, but we can provide some basic information that may help you decide."
Once you watch a football game in HDTV, you can't watch it any other way.
Heroscape, it's like legos combined with anachronistic wargames.
Huh? Really? HDTV didn't spring to mind at all when about a year ago the hand-down TV from my parents died. Well, I still wanted a TV at my place and these were the criteria:
In the end, I bought a CRT 83cm 16:9 "flat" screen for about 900€. The thing weights over 80kg, but I don't move it every day, do I? I understand that these days, such a TV is even less expensive because they're pushing Plasma and LCD screens.
In my eyes price/quality of a good CRT cannot be beaten by the newer technologies (yet). Of course, I could just as well not have bought a TV, because if I use it once a week it'll be a lot.

so much for news... anyway I think the next big thing will be 'real' dlp (digital light projection) sets. The limited but increasing number of theater ones can produce trillions of colors, and they can change color around 1000 times a second. For the consumer these days, one can only get a single chip system that uses a weird color wheel to translate grayscale into color. It looks good, but it kind of reminds me of those sets before color came around that came with cellophane color screens. Also, there is a weird rainbow effect sometimes with fast moving images. TI, the makers of the chip, has a pretty neat demo on their site. Essentially, the chip is just an array of millions of tiny mirrors that are capable of being toggled on or off quite fast. In 1 chip systems, which are avaliable from mitsubishi and some others, the grayscale deal is used. In 'real' three chip systems, each chip gets a primary color all to itself. The more time per second each mirror is 'on', the more of that color will appear in each pixel, = really good image. check it out.

I assume you're referring to front projection, as most HDTVs are projection in some form (DLP and CRT rear-projection). Anyway, front projection has its pros and cons, and you still have the same hoops to jump through. Do you go CRT, which is cheaper, but also bulkier and requires periodic calibration? Do you go with DLP and risk rainbow effects from color wheels? Do you go LCD and risk screendoor effects? Prices aren't too bad, in line with rear projection TVs (generally a bit cheaper), but you're not done once you've bought the projector.
Before you even consider front projection, you need to look at your viewing area. Is it sufficiently dark? Front projectors wash out very easily with very little ambient lighting. If your viewing area isn't dark enough (or can't be made dark enough), don't bother with front projection. Do you have the room for a projector? Theoretically, the size of the image is limitless (within the bounds of the projector's focusing ability and your ability to ignore huge pixels), but if you don't have enough space you're not going to get any larger size that what you could get with a cheaper rear-projection CRT. Did you budget for a good screen? A flat, white wall is a start, but most walls aren't that flat (go look at your walls -- chances are they have some amount of texture, which will cause weird shadowing) and a wall will never be as good as a purpose-built screen. How do you plan to mount everything? If you mount the projector to the ceiling it's no longer easily portable, but if you don't then it's susceptible to vibrations and the image can easily be blocked depending on where you place it.
When it's all said and done, unless you're really hardcore and plan on building a full home theater or portability is a huge priority and you don't care about sacrificing image quality to get it, you're better off with something else. What that something else might be will depend on your budget and the research you do (e.g. even if you can afford it, you probably don't want to buy a plasma TV since plasma is very susceptible to burn-in and has a relatively short lifespan compared to other technologies and can't be extended with a simple bulb change).
Ignoring all of that, front projection isn't any better or less hassle-free than rear-projection or flat-panel technologies. You're still going to have to do your homework on display technology (LCD, CRT, DLP, or plasma), you're still going to have to deal with idiot manufacturers configuring their sets to push red because it's more eye catching in the showroom (good sets let you calibrate that out, bad sets don't), and you'll still want to have your set professionally calibrated after a break-in period (I'd give it about 6 months based on my own viewing habits), and every year or two thereafter.
Something I've noticed about HDTV is that you almost have to look at the screen from a distance to see the most quality difference.
Having your face pressed up against the glass does make it difficult to judge quality differences.

If we're talking about value, why couldn't they take a look at some of the 30" CRTs that are out there from Samsung, Toshiba, Panasonic, etc.? They manage to get sets out there for well under $1,000. And, again, the complete omission of CRT RPTVs from their Editor's Choice list leaves out a lot of VERY good-looking sets (my parents' 57" Hitachi puts on a NICE show) that give more screen size bang for the buck.
I know flat-panel sets are cool, much easier to move around, and much easier to locate within a room, but it seems like a lot of folks have blinders on and assume that these are the only HDTV-ready sets on the market. This contributes to the notion that HDTV is still super-expensive. When you can get a Samsung 26" 16:9 CRT with HDMI input and an integrated HDTV receiver for $600 at retail, that's just not the case...
But I'm having a bit of trouble finding the parts of the articles where they say just how little, if any, Digital Rights Management are built into these televisions.
That would be one of the key factors to which HDTV to buy, for any geek, I would think.

Just throw out your TV and do something better with your time. And believe me, everything is better than watching those horrible reality shows, sitcoms with predictable jokes, news that makes you feel there are terrorists living in your basement, and soaps that seem to be designed to to make you stupid.
Really, TV is an insult to your intelligence. I'm boycotting them since 2004.

Note that many TVs have a "store demo mode" that is not really what you want to use at home.
As a good proportion of customers judges picture by brightness (geee look! that one is bright!) they always are set too bright and tend to wash out.
However, once you reset them to typical home conditions, the picture becomes much better.
You need to set both contrast and brightness in your own environment (preferably using a testcard) to make sure that the whole greyscale and colorscale are displayed correctly.
Still there is a definate small upperclass of screens that are way better than the rest.
Philips makes the "ambilight" models (37pf9986 and now 37pf9830) but I think they are not available in the US. Those really stand out when they are put between other LCD panels in a showroom. So much that you wonder why you would want to buy any of the others.
LCD also has some advantages over plasma.
- the power consumption is much lower (does not seem to be of interest to Americans, but still...)
- the front surface is dark and does not tend to mirror objects in the room
- there is no danger of burn-in of static displays
I don't know if there any Firewire ,PCIMCIA or USB2 HDTV cards . but for a PCI card the specs for example that the ATI -HDTV wonder requires are--
System Requirements:
Intel® Pentium® 4, Celeron(TM), AMD Athlon® or compatible, operating at 1.3GHz or greater
256MB of system memory
Available PCI slot for HDTV WONDER(TM) card
Graphics card with 64MB or greater of frame buffer and Microsoft DirectX 9.0 support
Installation software requires CD-ROM drive
Interactive Program guide requires Internet connection for listing updates
Remote Control receiver requires available USB port
Sound card with speakers
Problem with that one is no Linux drivers , but it gives you an idea of the required specs
The pcHDTV HD3000 has linux drivers I believe and MythTV supports it

The only problem I have with football in HD is the fairly uniform green field seems to cause problems with the compression algorithm. You get large blocks where it trys to make the field the exact same color green. But with that being said, watching football (or anything) in HD is always much better than standard analog broadcasts or even SD digital broadcasts.
