A:AnswerThere are no built in speakers. I had to buy a new set. I suggest getting something with a sub woofer. This monitor has a great picture so match it with a decent sound system.
A:AnswerYes, but only VGA and HDMI. There is no Display Port cable which I had to go out and buy because my laptop doesn't have an HDMI port and you can't run 1440p from VGA.
A:AnswerThe base is silver. The arm/leg going up to the monitor is black and silver. The monitor (other than the screen) is all black. There is no white anywhere.
A:AnswerI am not currently setup in a way to easily check this but it could be that you would have to select the monitor as the audio output in the Windows task bar "Select Playback Device".
A:AnswerIt will wall mount but not in the usual manner. You need a proprietary adapter that fits onto the arm that normally attaches to the base. It does not have a VESA mount.
