This Acer S271HL 27" Monitor has some pretty incredible clarity. I am using it as an extended display mounted on my wall above my 15 inch laptop. My productivity has increased because now I can actually run two apps at once side by side. I checked out some 4K or Ultru HD video on YouTube and was amazed. The ability this monitor has to obtain close to true black really enables the color and contrast pop. I love that it has the HDMI port so if you want to you can pull the audio straight from the monitor instead of your sound card. Windows 8 gives me another output to control with my volume control. I can see where you may want to use this feature depending on how your sound is configured. I tried out a few games and its performance did not quit, I saw no lag or latency in the frame rate. I would recommend this device to a friend in need of a large digital work space or large digital play ground for gaming.
