I would like a decent monitor for my MacBook Pro, around 22-inch. I got the HP 2309m, but it is not as good as I thought it would be. Text on it seems to be blurry or ghosting or something, it is hard to describe. And colours on it are too bright. I have calibrated it etc but cannot get it right, have also used SuperCal. Any recommendations? I don't want to spend more than £200 / $400.
