Using framebuffer with AOC E1649FWU monitor on Ubuntu 14.04

I see from the spec sheet that this monitor has
Display Colours: 262K
well lower that the typical 16.7 million.

So I'm guessing it is an older DL-1x5 and DL-1x0 hardware (total guess).

If I am right, then try using udlfb instead of udl+evdi.

Right now I am typing this on LinuxMint 17.3 with an old USB adaptor and udlfb on an ESXi virtual machine on a DELL T320 server.

If I use udl, I get your problem - just a blank screen, and even the "fbi" program can show nothing on the monitor (although it thinks it is).

So try blacklisting evdi and udl, and modprobe udlfb and then see if the framebuffer works.
