What do you mean by "unsharp" r u from some reason connected through DVI -> VGA, if so that could be source of blurred picture. The best option for that screan is DVI to DVI. Also try calibrating an experimenting with the gamma value. For instance I find my custom gamma value much better than the one that was automatically applied to the screen. You might be willing to apply one of those colour profiles (attached), they r all custom made profiles for various screens. Personally, I often find my own settings much better the default ones. But of course, to great extent that will be a matter of taste.Fantastic monitor. Text could be a little sharper in OS X though. I run this on my Mac Mini. If anyone has a fix for unsharp text, please let me know.
