today, my university department received our 23" ACD batch order and all of us were so excited about brand new screens, larger working space...
but the initial excitement soon turned into disappointment as we discovered that 4 out of 5 displays we received had an obvious "pink cast"... especially when we looked at shades of grey / metallic scheme of Mac OS X. We tried software and hardware calibrations but the pink cast remained. To confirm this, we compared them to the PowerBooks, eMacs and 20" ACD... we even borrowed a 30" ACD from another staff and placed each of them next to the 23" ACD. It is a truly disappointing quality from Apple.
secondly, all 5 had faint grey vertical bands (about 1 pixel wide). These bands were quite obvious towards the centre of the screen. We tried viewing vector images with curves and solid colour lines on these displays. They did not look as good as ones on the 20" or 30"ACD because the grey vertical bands somehow 'distorted' these line when we examined closely (hard to describe in words, but the output was definitely inferior to Dell 24" monitor.
lastly, when we tried watching DVDs, switching off all lights in the room, the display backlight was quite uneven (backlight bleeding at the edge of the screen) in 3 out of 5 (the other 2 were acceptable). We used Pixel Check to show solid black image in fullscreen and the backlight bleeding seen in a dark room made the 23" ACD look really ugly.
we initially expected some dead / stuck / hot pixels. All of them did not have any dead pixel as far as we could see. But we concluded that the 23" ACD is the worst among all of Apple displays (except for the eMac CRT and 15" PowerBook).
All 5 displays has been rejected and we will claim a refund from the supplier.
Sorry for making this sound like a rant.
If you are looking for a 23" ACD... i would urge you not to buy it until the display has been updated.
