Gaming Point Of View

No ghosting even when playing Left for Dead 2, or BluRay movies.
The power button is one of the best designs I've seen. It is a touch sensitive button which is located in the center of the stand just below the screen. Note that this monitor is not compatible with VESA mounting. The "mother" of the stand is actually part of the monitor. Only the base can be removed.
The Bad
The stand is horrible, is very weak, but that seems standard for computer monitors from Samsung. There is also no swivel or height adjustments, just tilt. Monitor buttons are on the side of the monitor making them difficult to use, but remains at the forefront in looking clean, which is not bad.
What Should Get Fixed
1. The stand. Make it sturdier and with pivot and some height adjustments
2.Text Should be Clearer
That's all.
This is a great monitor, just not that perfect.
