I'm sorry to write in English, feel free to anwser in German.
I have to TFT's on my shortlist, the LCD1990SXI and the LCD1990SX.
The main differences are:
1990SX: PVA panel, 1500:1 contrast ratio and a brightness of 250 cd.
1990SXI: S-IPS panel, 600:1 contrast ratio and a brightness of 270 cd.
Both have a 12 bit LUT and the rest of the features is allmost the same.
I will primarily use it for photography work. Which screen will be the best for me to buy? The price is allmost the same.
