I have just ordered the HP2475w. It should be here within a week. What issues have you discovered?
I don't want to scare you, I hope I have a faulty unit and yours will be fine - mine will be replaced Monday, I'll keep you posted.
My first unit had a faulty DVI connection, an unstable HDMI connection and the system rebooted every time the resolution changed for instance for playing a game, although that may be caused by the graphics board, I'm not sure. But the real deal breaker was that the screen isn't uniform in colour. If you display a full white screen, it is noticably more red to the right side than in the centre. If you display two identical black-and-white pictures in Photoshop next to each other, the one on the right looks warmer than the one on the left, which makes it impossible to do subtle sepia toning with any degree of accuracy. I discussed this with another forum member in a private e-mail conversation, he noticed it as well in his unit, but it went away when he did a second calibration at 6500K. I calibrated with an Eye-One Display2 at 5000K and at 6500K, but in both cases the hue shift remained. If the second unit shows the same hue shift, I will get a different monitor alltogether. I hope the next one's OK, because it is otherwise a terrific screen, particularly for the price.
And it surprises me, I read the reviews over at tftcentral and prad.de, and they specifically measured screen uniformity and noticed a slight unevenness in brightness, which I could live with, but they did not notice any hue shift, so their test units may have been OK. The inputs are now fairly stable, I could live with that, but I can't live with the colour shift. Good luck with your unit,
