Yeah, just be aware that DP to HDMI/DVI isn't really a 'dongle' in the
usual sense, the whole internal hardware is running in HDMI mode, just
sending the data over the DP wires. The cable then just converts the
signal levels.
So, our driver sees a regular HDMI output, which is vastly simpler than
the DP to VGA dongles which look like DP to the computer and VGA to the
monitor.
I've tried a bunch of monitors using this mode and it's always worked
just fine; you might try a different cable, or test with a different
monitor if you can find one.
