Buying a HD TV ?
Here are some recommendations on what to look out for...
I'd go for a LCD Vs a Plasma because although you will get a smaller size for the same money with an LCD they usually provide better resolution. If you are even going to use this TV as a pc monitor the desktop size will be massive.
i.e. In comparisons you can get a 42" plasma when a 37" LCD will cost the same money.
TV's and specifically HD-TVs are measured in the vertical resolution, the number of lines of information it can display down the screen. The horizontal resolution can be anything depending on how wide the "widescreen" is.
Most TVs that you see advertised in Dixons etc marked "HD Ready" would not actually be "true HD" resolution.
"Normal" PAL or NTSC TV is approx 480 lines of information. That’s why when you hook up your computer to your TV you have to drop the resolution right down before it looks ok.
Most "HD Ready" tv's display 720 lines of information which will show a visible improvement over standard TV but "true" HD TV displays have at least 1080 lines (or pixels) of information. There are usually letters after each like 1080p Vs 1080i the "p" stands for "progressive scan" and the "I" is interlaced. 1080p is better. The difference between the 2 is easily found on google i.e. http://www.projectorcentral.com/video_signals.htm
Basically Progressive scan is better even if it is lower resolution for some types of programming (i.e. sports), so 720p would be better than 1080i for fast moving scenes.
So your target resolution to look for will be around the 1920x1080 mark, this means it will be 1920 pixels wide by 1080 high in resolution. If hooking this up to your computer (i.e. Media Center) your graphics card is going to be working pretty hard because doing the maths it has to push out 2073600 pixels for every frame of a movie. This will tax even the better pc graphics cards so investing in a good card with plenty of memory is advisable.
If you are not using it through a computer and just watching TV (aka like normal well adjusted people), then you could be disappointed with the results of your new TV depending on which signal you are putting through it. I have regular NTL analogue TV (standard coax cable) at home and even on my 32" widescreen display it can look crap. Magnify a basic signal to a 42" 1080 screen the stretching that will occur to upscale this signal will give mixed results in picture quality.
I heard somewhere that Sky satellite box's have promised HD support (probably 720) as well as Freeview and NTL digital boxes which should improve the signal going into the TV. In certain parts of the US you can get a over-the-air HD receiver that picks up a true HD signal for display, we will have to wait for Irish stations to start this for quite a while so your best option is the set top box.
To get a digital signal you will need as many HDMI or DVI connectors as possible on the TV. Most PC graphics cards all have DVI connectors on them, HDMI connectors are less common.

A nice 1080p 37" TV for $1600 is the Westinghouse LVM-37, although no HDMI input
