i got mine at 55 brightness, 50 contrast, Magic* are off. pretty clear images with very good colour representation.
fantastic monitor, just need to wipe the outside once in a while due to dust. (well, with normal monitors, you don't notice as easily)
the T series are the best TN panels you can get really.
Mine had a bright corner and it was never quite uniform from top to bottom, always an edge dimmer or darker than the rest of the screen, no matter how I tilted it I could never get acceptable black and dark contrasts.
