C3422WE, webcam is unusable

The C3422WE Video conferencing monitor concept is nice but the webcam video quality is very bad. The picture is blurry, noisy, color balance is off, and dark. I have both Mac and Windows machines connected to the monitor. I think windows picture just a little bit better but overall the webcam quality is bad.

I ended up connecting my old webcam (~5 years old) and picture is much better. Comparing the webcam to MacBook Pro is like day and night.

Moreover, the webcam is not support by Dell's DDPM software so you cannot adjust anything for the webcam.

If you have any idea how to make the webcam usable, please let me know.
