Would recommend going with all of Acer's monitors before even considering these ones. I have the equivalent to this one made from Acer in my attic and smokes this one out of the water bar none.

    Pretty spotty quality but works with 3 types of connections, HDMI, VGA, and DVI witch is why I chose this one to begin with. Also isn't very bright even fully adjusted.

Especially like the night mode option. Very sharp, clear, great color. Can't go wrong with this FHD monitor. Great for gaming. Perfect size for a smaller desk too.

Pros: The picture is pretty good for the price VGA/DVI/HDMI ports Cons: Stand is not height adjustable No speakers No port for audio to plug in your own speakers or ear/headphones Neither DVI nor HDMI cable included

I first bought an AOC 22" that I brought back because the colors would wash out badly. This monitor is way better. I had to turn down the brightness on this to 50 because it is so bright. The AOC has a brightness of only "200 cd/m2" and the HP has "250 cd/m²" which makes a big difference.

Seems to be ok, but I've only used it a couple times since it was purchased. Colors show up very well.

The picture is pretty good. Alas, I liked my old HP monitor with gooseneck flat square pedestal better. (A place to stash my bills)

Perfect, if only it had a stand.

    Would be awesome if it came with a stand

    UNable to put in on my desk because it does not have a stand.
