This article by George Ou should help sort things out. He covers the advantages and disadvantages of:

Projection: Pro: price. Con: viewing angle.
Plasma:Pro: resolution, colour, viewing angle. Con: price.
LCD:Pro: picture quality. Con: expensive large size sets.

George also advises, bluntly, against getting suckered into buying so-called high end cables:

Consumers need to get the concept of "monster cables" out of their minds since they DO NOT apply to the digital world. There is zero difference in quality between the cheapest $12 HDMI to DVI cable versus the $100 gold plated "monster cable".

He also makes available some colour gradient graphics and explains how to use them in testing the colour quality of an HDTV.

This is a great piece for anyone in the market for a new HDTV, and it's especially useful for those of us that may be more than a little confused and/or overwhelmed by variations in HDTV technology.

Here's the criteria they were after, from the article:

It must be cheap. Total budget for all materials to make a 100" diagonal 16:9 screen, including frame, must be less than $100.

It must be simple and quick to assemble. We did not want to make a lifetime hobby out of making a screen. We wanted the materials to be easy to find, and we wanted to put it together in less than two hours of invested labor.

It must be easy to install. We wanted a no muss, no fuss solution with a fixed frame that we could hang on a wall in a matter of minutes.

It must perform!!! We had no delusions that we could invest a hundred bucks and a couple hours labor and come up with a screen that would match the quality of the Stewart screens we use in the projection labs. But how close could we come? That was the challenge. And as you will see below, the results were surprisingly good.

If the cost of the screen is what's been holding you back from buying a projector, perhaps a frugal DIY solution such as this one will be your tipping point.

The installer lists the tools you'll need for the hanging and also covers finding an appropriate mount location, stud finding, cabling issues, etc.

About.com also offers some wall mounting instructions, including tips on handling situations where cables aren't (or can't be, for whatever reason) behind the wall:

We can either place an obstacle under the television, which would look odd, or we can cheat the eye with camouflage. I have a friend who had this very problem, and his solution was to create a molding that would be used as a cover for his cables. He painted the molding the same colour of his wall, and when placed over the cables it looks like part of the wall. Granted, it's raised about 2-3 inches off the wall, but it looks very natural. As far as supplies, small strips of wood (a 1x2 for the sides and 1x4 for the face) cut to the length of the TV to the floor should be enough to make such a piece.

Topics covered include cabling choices, speaker positioning, video tuning, connection types and a ton more. Here's a television tip, from the article:

Try this simple visual test to determine if you have your video image too bright or contrasty. Look at any white area on the screen during scenes from live TV or a movie. It could be the white shirt or blouse on an actor or TV host. Are you able to see detail within the white areas? If you can't, then you are likely running the brightness too high, which washes out fine detail in bright areas. So lower the brightness and/or contrast. There's a reason why control rooms for TV productions and telecasts are always dimly lit: it's because video images on the monitors look best in a dim or darker room and the greatest range of colors and tones can be displayed.

Alan's website is also packed full of home theatre information and worth checking out. ]]> http://www.househacker.com/permanent/Detailed-Article-on-Setting-up-your-First-Home-Theatre top 20 overall projectors.]]> http://www.househacker.com/permanent/Find-a-Home-Theatre-Projector-with-this-Exhaustive-Database Engadget has posted a useful step-by-step howto on building your own Tivo-like home theatre PC (HTPC) using MythTV. They list each piece of hardware they used on the way to a successful, smooth install. From the site:

The total for the base system is $988. The addition of the TV tuners brings the grand total to $1126.

This price is probably beatable if you opt for a lower end processor, which will save you some money and really wont cost too much performance-wise provided the tuner cards you choose do hardware encoding. Tuner based encoding takes the vast majority of processing load off of the CPU. That being said, faster is always better when it comes to CPUs, generally speaking, so too severe a drop in clock speed will hamper menu navigation and other features which will detract from the snappy, slick user interface that you want in a PVR. If you're not too Linux savvy and aren't ready to do a manual install, a great way to set up MythTV on a PC is by using KnoppMyth. KnoppMyth is available on a downloadable, bootable CD that aims to make the MythTV installation as straightforward, user-friendly and painless as possible. If your system meets the hardware requirements, the CD will install MythTV onto your system while prompting you for only a minimal amount of configuration questions. If you encounter problems along the way, the KnoppMyth forum is invaluable. The site's admin, Cecil, not only tirelessly develops KnoppMyth, but also personally answers an unbelievable amount of questions on the forum, which, by the way, is packed full of information on getting up and running with MythTV - useful no matter what your method of installation.]]> http://www.househacker.com/permanent/Build-Your-Own-Home-Theatre-PC E-ink. The clock is only 3mm thick and can bend around pillars, making it visible from many angles. This would be a fine addition to any recroom, fitting in nicely with your 360 degree LED television. From Yahoo:

Citizen will start production of the clock early next year upon receiving orders with a price tag at 500,000-600,000 yen (4,200-5,000 dollars) each.

Those of you thinking of running your PC through a 1080p set should be aware that you may not necessarily get to use all that extra resolution--even if you have the right high-end graphics card. For instance, the Sharp set we tested allows you to max out at only 1,280x1,024 resolution while the less-expensive Westinghouse LVM-37W1, along with Samsung's 1080p RPTVs and one series of high-end sets from Mitsubishi, accept true 1,920x1,080 resolution from a PC.
