I managed to solve my issue: I found a passive DisplayPort to HDMI
adapter that works (the colors on the TV are as expected).
But I still think that there is a software issue, or an issue that ca be
solved with software, since with the exact same hardware the colors are
fine with certain
I did a new test with another laptop with Intel graphics and Ubuntu
16.04, but which has an HDMI port, connected to one of the three Samsung
TVs, and the colors look fine.
Also, for what it's worth, I compared the EDID information (obtained

And I still encounter the problem.
I've run apport-collect, as can be seen above. For this I've used a
