I've owned the Acer AL226W and the Samsung 226BW, and the colours are great. Pretty accurate. The problem I'm seeing with the 22" LCDs is that on vertical pitch, the top portion of the display gets darker than the lower part. The lower you go (pitch looking up), the more you notice the top of the screen getting darker in comparison to the bottom. This plays such a huge factor when it comes to viewing colours.
Initially from what I was told, this may have to do with a faulty display. But I've tested about 5 different LCD monitors (all 22"), and they all did that. The only ones that I didn't notice this issue with was the Apple Cinema displays (00), the LG 23" HD monitor (00), and a smaller 20" NEC LCD 2270nx display.
I'm just wondering if this is just an issue with your run of the mill 22" displays. Can anyone explain this strange "phenomenom", and perhaps recommend an affordable 22" LCD that doesn't have this issue. thanks.
