Summary: I'm on my second Samsung SyncMaster 204B and experiencing the same problems as the first. Whenever you put your computer into sleep mode or switch off the monitor, a problem develops: When you switch it back on, the picture becomes gradually dimmer with a noticeable flicker over time. My first one eventually died altogether within warranty, and Samsung sent me a replacement. It's been maybe six months and the same thing is happening.
Summary: I concur with the previous reviews. There is one thing that I want to add. My wife liked this monitor in the store. But, she had been using a 21" CRT at 1024 x 768, and I was very concerned that a jump from there to 1600 x 1200 would be more of a font size reduction than she bargained for. And, my general feeling about LCD's is that, if you don't use them at their native resolution, they don't look all that good. I'm happy to report that I was right and wrong.
Summary: For the money this Monitor is great, especially if you are using it just for surfing or word-processing! It has some of the best specs out there such as very fast response and natural looking colors. HOWEVER, its not the right choice for pro-level graphic design or photo editing. The viewing angle is so limited that there is a major vertical shift in brightness of the screen. No matter how I adjust, the top of the screen remains significantly darker than the bottom.
