It's well known that before launching any monitor officially, Dell plays hide-and-seek game with tech geeks. No one knowns why Dell likes to unofficially put products on it's website before going official with them. The 22-inch S2209W, and 23-inch S2309W features 16:9 aspect ratio and 1920x1080 resolution. Nothing much is known about the 22-incher but it's known that the 23-incher sports 1,000:1 contrast ratio, 5ms response time and 300cd/m2 brightness.
