Rated 5 out of 5 by from nice features Love my new LG Monitor. Perfect size for my desk. No neck strain trying to use a larger size screen or eye strain using a smaller size screen. Very light weight, perfect clarity, overall a great product. Very reasonable price also. I would recommend this product to anyone looking for a great monitor at a really good price.

Rated 5 out of 5 by from Really nice monitor and easy on the eyes My old monitor died a while back so I started looking for another one. I wanted a 27” and looked at several. I settled on this one and so far it’s everything I wanted and then some, I’m very happy with it.

Is this monitor mountable on a wall or desk mount arms?

Is this monitor mountable on a desk-mount arm assembly?
Asked by: ashkrishem

Does this monitor support audio in as well as video in using an HDMI Cable?

I own this product and have my Xbox One connected to it via HDMI, the video works perfectly, however there is no sound whether I turn up the volume on the monitor (and it has a volume control so I expected sound) or hook it up to an external speaker.
Asked by: PeterT
According to the information on page 9 of your owner’s manual, the HDMI connection transmits the digital video and audio signals from your PC or AV device to the monitor set. The audio will only be available through the headphone jack, as this monitor has no speakers available.
