I used dell, the only problem i faced was the screen too bright at times. I need to reduce the gamma, brightness and contrast to my liking. But brighter LCD is better than dimmer ones. You can always reduce it later. As for getting a gaming LCD make sure that the monitor support no less than 5ms response rate. All LCD has its own native resolution, if you're getting 19" LCD, make sure that your PC is up to the task to display its native resolution (mine 1280*1024). To use less than its native resolution will just resulting in pixel stretching.
