From a TV perspective I doubt that TFT LCD technology will ever be as good as a conventional CRT based TV, especially when it comes to color saturation. Plasma technology is much better for TV since it uses phosphor to generate the color.
The major problem is LCD?s use a matrix of cells that define the native resolution of the screen. The dot pitch multiplied by the resolution defines the size of the panel. Thus a low-resolution panel would need a very a large dot pitch to work as a TV.
Standard TV is extremely low resolution compared to today?s computer monitors. In order to get a clean picture the LCD TV would need to run at TV?s native resolution. HDTV will be better at 1900 x 1024 resolution, however this is a 16:9 format and is not the optimal aspect ratio for computer work. Most computer users prefer 4:3 aspect ratio.
TV?s and computer monitors although similar in many ways are designed for two completely different applications, thus there will always be a trade off when you try to use one for the other. If you want the best TV, buy a TV. If you want the best computer monitor buy a computer monitor.
The trend now is to add a TV tuner to a standard 17 ? 18? LCD monitors. 17 and 18? LCD monitors have a native resolution of 1280 x 1024. They typically look great as a computer monitor however they loose focus and become grainy due to the scaling of the TV signal to the 1280 x 1024 format. You will be very disappointed if you expect your new LCD monitor (with TV tuner) to have as crisp and clear TV image and color saturation as your standard TV.
