I had a nineteen-inch monitor for a long time, and I never had any trouble with it. I finally just wanted a bigger monitor, and I had been told that Samsung was one of the top two makers. If you have ever gone from a small monitor to big one, you know that it is almost like getting a new computer, so dramatic is the difference in ease of reading web pages and in navigating. I had no trouble setting the monitor up to provide the proper resolution for my text and games. The default brightness setting was too bright for me, but I was able to change it to my preferred brightness without difficulty. The games and videos I watch on it when I am supposed to be working seem almost as clear as the video I watch on the regular television in the living room. The only thing I can't report on is the longevity, but so far there has not been a single glitch or indication of any possible problem. Altogether this has been an excellent purchase.
