Question: overall size
Document: The stand is flimsy and allows the screen to shake.The screen controls are off to the right side and are black on black; need a flashlight to read.The overall appearance is cheap (the trim around the screen is flat black); compared to HP monitors of the past.Would not recommend spending your money on this.
I am still a bit bummed about the price though (shave $50 off the price and its a great 5 star review). The monitor even has speakers, so the HDMI input would of been awesome for what I mentioned above or even a Roku or Apple TV setup. Overall, a good deal, not a great deal.
Awesome color and great size. I dislike not having speakers but that was my choice. Picture quality is out of this world!
I just received my monitor and it is very nice so far. I am impressed with the size and the vividness of the colors. Good deal for the price.
I bought it for second monitor. Good size and good price!I love it, even though it doesn't have audio.
Great monitor, crystal clear  picture with great size to work on monster excel spreadsheets.Can't go wrong with this monitor.
My only slight complaint is that the stands are a little wobbly...only evident when someone bumps the desk. Otherwise, great picture quality and size! Especially with 2 of them.
I had a smaller 17 inch monitor and when I purchased a new HP computer, I purchased this monitor. It is perfect for its size and clarity.
I picked up this monitor for well under $100 between Thanksgiving and Christmas 2013. Works well. Worth the price for sure. No exciting features. Perfect size. Not too big, not too small. Nice clear image.
The picture quality is pretty good but the base and material seems pretty flimsy. I think 23 inches is a perfect size so if you are looking to upgrade from a smaller model you will be satisfied with the size, any bigger seems too much.
Answer: 21.75" x 13.5"  The stand lifts it 2.75" above the desktop
