There is a dark line of pixels from top to bottom of screen from day 1. It wasn't there when I first plugged it in, but started after about an hour and never went away. It's still there with another computer and different hook-up so I know it's the monitor itself.
The monitor looks really, really good! But, unfortunately, the stand is flimsy and inadequate because you cannot raise the monitor vertically. The stand will let you tilt forward and backward -- which is really helpful -- but the stand does not have the ability to raise the monitor up. I liked the price point and features of the HP 27fw -- it is awesome. I would have paid $20 more for a better stand. But don't get me wrong, the monitor looks really, really good, and I am really glad about that.
HP always delivers quality products in my experience. The monitor itself is great and was my main reason for purchase. The speakers were a plus to try and save some desk space. Unfortunately, the sound severely underperforms. I wasn't expecting high quality sound by any means, but my phone speaker is better than this is. If you don't care about the sound so much, I highly recommend the monitor. If the speakers are important and you're expecting even decent sound, then I'd pass.
