Great 4K Monitor with Good Price
The AOC 27” 4K monitor delivers great picture quality with sharp, vibrant visuals at a very reasonable price. Setup was easy, and the built-in speakers are surprisingly good for everyday use. Perfect for work, media, and casual gaming. Highly recommend for the value!

Great value for a high quality monitor
I wanted to save money instead and after reading numerous reviews I decided on this one. It is looks great, was very easy to set up, sound quality is awesome and the picture is very clear. The only extra I wish it had is the ability to move it upward to be more at my true eye level. I fixed that by adding a little drawer box below.

Good for the price
Good monitor, especially for the price. Clarity is excellent. Minus one star because the brightness is just okay and the speakers and very lackluster.

Excellent screen from center view, garbage speakers
I'm using this with a Mac Mini. I wanted a monitor with sound for an all-in-one solution via HDMI. The screen has very nice clarity, but viewing angle matters. Anything left or right more than 20° from dead center is distinctly faded. The internal speakers are garbage, very tinny and faint. I had to buy an external set because the sound is unacceptable.

Buen monitor, pero...
El monitor cumple con lo indicado en el anuncio, sin embargo no me gustó el hecho de que la pantalla no tuviera plástico protector con el que viene de fábrica y que la caja de cartón tuviera golpes. Ambos detalles dan la impresión de ser un artículo de segunda mano.
