Resolution not good after Windows 8.1 upgrade

[ronnyl]

We are a Dell reseller, and one of our customers bought Dell xps 13 computer, Dell 27" monitor and USB 3.0 docking. Readabillity was ok when running Windows 8, but after upgrading to Windows 8.1 text output is clearly reduced. Images appear to be quite ok, but text appear somewhat smeary and is difficult to read in lenghts of time.

Our customer have 3 identical sets of computer/monitor/docking. Both that have been upgraded to Windows 8.1 have the excact same issues, but the one still running on Windows 8 is ok.

For the record, the computers are updated, all drivers seems to be updated as well, and running the latest software from DisplayLink.

Please help!

Edit! I have posted the same question in the Windows group, as this group is not monitored, according to one of the other posts here...
