I ADORE this monitor, and that I got it at an exceptional price - $600. Like all OLED monitors, the colors are brilliant, and the true blacks make the picture pop.

High quality and well made monitor with outstanding price for performance

I've always like Dell monitors and this one is outstanding. Nice matt colors and very sharp. The 32 inch size is great and any larger would cause me to have to move my head too much. The depth of view is great and viewing angle is excellent. The performance is great and I haven't run too many games through it yet, but the ones I have are perfect. Great price on a fantastic monitor.
