If you've still got that bulky monitor on your desk, now might be the time to upgrade to an LCD monitor. They're smaller, cheaper and actually bigger than your old CRT monitor.
First off, they have a much smaller footprint than your normal monitor. What that means is it takes up much less space on your desk. It's not nearly as bulky.
Second, LCD monitors have drastically dropped in price. They are much cheaper than they ever have been before. You can routinely find 19 inch LCD monitors for sale for under $200. Just a few years ago, LCD monitors were double to triple the price of a normal CRT monitor. These prices have equalized just in the last year or two.
Third, it's possible to get even larger LCD monitors. Most people never went larger than a 17" CRT monitor, because any larger and they got really huge and bulky. But today, it's not hard to find a reasonably priced 22" monitor and above. So, you can either have your graphics much larger and easier to read, or you can fit more on your screen. Either way you win.
Fourth, with most LCD Monitors the display quality has improved dramatically. Now, it's not necessary to sacrifice quality in order to have a smaller monitor. In most cases, LCD monitors are brighter, faster, and clearer than ordinary CRT monitors.
Fifth, the newer models of computers and graphic cards only have digital outputs which no longer support older CRT monitors. Because of this increasing trend, CRT monitors are being eliminated from the market, and no longer supported.
There really is nothing holding you back any longer. If you need a quick upgrade, or are looking for an improved computing experience. Now is the time to move towards a new LCD monitor.
