Works very well. Attention: for the DVI connection, you need a Dual Link cable otherwise the monitor will not receive any signal.
And for HDMI, you need a standard that can handle 1440p resolution (I think it's 1.3 and > , but you'll have to check) otherwise you'll have access to resolutions lower than or equal to 1080p.
The colours are perfect (really).
I haven't tested any of the extended features (USB hub, remote control, split screen), so I can't give my opinion on them.
