Monitor stand adjustment is fairly limited.

3 agree

only a single digital input - and it's HDMI not the much more common DVI

2 agree

hollow stand is cheap and too thin to properly house the included proprietary cables

2 agree

cheap looking glossy black plastic stand and bezels

1 agrees

TN display panel - cheap to produce and sell at the expense of colour quality and viewing angles

1 agrees

A bit too bright for some and turning the brightness down seems to affect the overall picture quality.

The SyncMaster S23A550H is a 23" LED computer monitor that is part of Samsung's 5 series and was released in the first quarter of 2011. This monitor has eco friendly features and an elegant see through base, and the LED backlit screen can display a resolution of 1920 X 1080 pixels with a contrast ratio of 5,000,000:1. Two sensors help conserve energy and prolong lifespan, one of which is an ambient light detector which automatically reduces brightness in a dark room and conversely increases brightness in a bright room. The other is a motion sensor or more accurately a 'Pyrolectric Infrared Ray' or PIR sensor that will dim or turn off the screen when you leave and alternately brighten or turn on when you enter a designated area in front of the monitor. Other energy saving modes such as 50%, 25% and Off Timer help to further reduce power consumption, and Samsung's Magic Angle provides 5 different modes to select from depending on where the monitor will be viewed from. Inputs include one HDMI and one D-sub VGA computer input. D-sub cable is included.
