Mode rejected (Debian 9, kernel 4.9.0, DLM 4.1)
EDIT Resolved. I found that the DL-5910 chipset in the Dell D3100 can only support resolutions up to 2560x1080 on the HDMI outputs. I switched to the DisplayPort output and was able to get it to work.
I'm trying to connect an ultrawide as a second monitor to my Dell XPS 13 9343 via the D3100 port replicator. I have installed the DisplayLink software and, after a lot of experimentation and rain dancing, have been able to get something to appear on the monitor. Unfortunately the native resolution is rejected. The following kernel logs are generated (parenthesized text on the last three lines is mine): Code:

When I tried the "modesetting" driver, the monitor would not appear in "xrandr --listproviders": Code:
