Today I received a Dell D6000 and have been trying it out.
I have a 38" ultra wide monitor 3840x1600 and with my eyes I find that resolution difficult to work with, so when plugged into my MacBook I have it scaled to 3008x1253. When connected using the D6000 only 3840x1600 or 2560x1080 are available. In DisplayLink Manager 1.8.0 I have ticked 'Enable experimental 3008x 2560x modes' and on one occasion using HDMI I managed to get it to use 3008x1253. But since then no luck using HDMI or DP to get 3008x1253 working again.
I have the latest DisplayLink Manager installed and I updated the D6000 to the latest firmware.
Just wondering if anyone else has got the 3008x mode working?
