To the specification and the positive characteristics I want nothing more to say, there are already plenty of reviews.
The biggest negative point are the distorted colors. I have made different settings, the recommendations from the PRAD test, but I had an enormous purple-stitch. In addition to an IPS panel (Dell screen) that falls on again stronger.
As an example, the default Windows 7 background with the logo in the center. The logo itself is relatively colorfast, but this decreases greatly towards Bildschirmrrand. The real blue of the background is then purple. And that at a frontal seating position.
The second negative point is the background illumination. If one has a completely black screen, you realize in the corners and in the bottom of the screen a stronger illumination. During normal office use, it is nothing to see, because it often works with brighter images / programs. While looking film, it falls but immediately and disruptive. Eventually you get used to it over time.
On PRAD there is an image for illuminating with longer exposure time. My BenQ screen looked partly in normal operation with black background like this.
I have the screen returned and a Dell U2412M ordered me with an IPS panel and am more than satisfied. The colors look real, the lighting is perfect and of a backlight flickering I realize fortunately nothing. Of course, the Dell is expensive, but worth every penny.
