I have 24 U2722D monitors at my facility, and I'm having some flickering and severe image retention problems that come and go at random. The problem is certainly the monitor and not the graphics card or cables. Even with the HDMI and DisplayPort cable disconnected, a ghost of desktop icons is still visible combined with a flicker. This comes and goes about 2 or 3 times a day.

The user here mentioned he is running U2722D firmware version MT3102 while all of my U2722D are running MT3101.
The download page for the U2722D monitor does not show any firmware updates. So to eliminate my problem is (or is not) a firmware issue, how can I get hold of the version mentioned in his post (version MT3102)?

Thank you for your time.
