--- Comment #38 from Roberto C. Sánchez <roberto at connexer.com> ---
I have a Dell XPS13 9350 that I am using with a DA200 adapter.  I am running
Debian Stretch with Linux kernel 4.9 (planned for release in April/May 2017). 
I have the version 1.26 SKL DMC firmware installed and continually experienced
the "no HDMI output" problem described here and elsewhere.

After reading here how some had seen success with lower resolutions I decided
to experiment with the settings to see if I could get it to work.  I was able
to get 1920x1080 resolution out of the DA200 as long as I chose resolution
"1920x1080i" (it has to be the one with 'i' at the end) and the refresh rate
has to be "30 Hz (NTSC)".  The monitor on which I tried this is a 23" LG
Flatron E3250V.

If I can provide any additional information that would help in resolving this
bug, please let me know.
