Attached is a HP2310ti (Touch). The colors are fine (comparable with the direct connection to the PC).
Whether the touch function still works, I have not yet tested.
Fact 1:
Connect with USB and monitor via VGA is fixed and easily.
Fact 2:
Windows 7 will recognize it immediately and it can be easily set up as an additional screen.
Fact 3:
Dropouts or problems with video outputs, there is no me.
CONCLUSION:
I recommend this part even further, so good I find that (and I recommend pretty little further).
