What is the difference between the flat screen monitor and the gentle giant of yesteryear? Weight is one. An LCD is so light it can be mounted on the wall. How's that for taking up less space? And if you do have it on the desk it takes up much less room. It can be moved too, without you having to spend a week in traction while your back recovers.
But best of all, the LCD screen does not flicker, nor reflect light so is ideal for if those who have to spend hours at the computer. But there's more; the LCD doesn't generate the same heat as the CRT - and it takes less energy to run. There is more usable display area and the native resolution is sharper.
But if you are watching your budget and don't mind the space that they take up, then the CRT offers a viable alternative. They are ideal for publishers and designers because of the precise colour matching ability. The image quality is great for gaming and for graphics, while video and movies are blur-free and of high quality. For the energy conscious, the sleep mode will save energy - and you can get them in true flat screen versions. So really what it comes down to is your budget and space.
