Summary: I wouldn't say its totally bad. Like I said I did leave it on at times throughout the night. But I have done this regularly with all my monitors. For the price I think you can do better. But don't buy it if you like the fact that it has speakers.
Pros: Looks good and the display is good. Didn't look unbelievable or anything like that. I would say it was good, not great.
Summary: I bought this monitor primarily for use with my XBOX 360 (playing games like Battlefield 3). Unfortunately the image quality was not was I was expecting (connected with HDMI). The home screen was grainy and somewhat blurry. Even after several minutes of trying to play with the settings (both on the monitor and the xbox) I could not get a decent picture. Also, there seems to be quite a bit of light bleed and blacks seem to be gray.
Summary: I've had this monitor for a few months... it is time to review. The colors are really bad on the monitor. Every month since I've had it, I finally get fed up and spend a half hour trying to calibrate the colors. Most shades of light gray are invisible to me... they just look white. I suspect that is fine for the average person who just browses the web and reads email... but when detail matters, this just isn't acceptable.
Summary: I only had seen ONE review where someone mentioned having an issue with the way the monitor panel is 'coated' for anti reflectivity. I thought I'd ignore it as a one off, or a picky person. Well I got my monitor, which was to sit side-by-side with an older 23" Acer LCD, and indeed there is an odd coating on the panel that is very annoying. it's like it had a coat of grease or smudge.... a sparkly pattern.
Summary: Apart from the anti-glare (that due to not being mentioned in the specs on any site, I was unaware was on this monitor), it's an excellent monitor. The annoying part about the anti-glare (for those that don't know) is that it makes the monitor look like someone has sprayed it with water or smeared grime all over it.
