It looks beautiful for a start, but there are some small display issues with the screen. There seems to be a ghost to the right hand side of some white or black areas on the screen.
For example, a white text box will have a very faint white stripe coming form the right hand side stretching to the edge of the screen. I gave the monitor some time to see if it would fix itself, and it never. I checked the connections and whilst moving the video cable it got a lot worse. So after some minor sable adjusting and tilting the monitor a tad up the way it's not as noticable.
It could just be a cheap cable, I'll test out some older cables to see if there is a difference.
I have a feeling this could just be me, so don't let it impact your choice in monitor too much. Other than the problems stated though it's a very nice monitor, very sleek and the picture is high quality.
I emailed BenQ customer support and they were very friendly, and I asked if they could send me a new cable free of charge to test it out with and they were happy to oblige. UNfortunatly the cable took 8 days to get here, but thankfully it solved all the issues. Chances are it was just a one off, so don't let this put you off purchashing this product. Even if you do have issues, the support were very helpfull.
