I use it and the solution is always the same: Fixate the EDID, use drm_kms_helper to force on the output
First decide what functions / features you expect from a system. Then decide for the hardware. Don't waste your money on crap.

which desktop are you using? This is a known bug with XFCE, for which a fix hasn't yet migrated downstream to ubuntu. If you're using that, switch to LDXE, or load kodi in stand-alone mode, and the problem should (hopefully) go away.

No - don't have time anyways these times. From a very short look: Try a newer kernel 4.8+

i made some tests. it never works with kernel 4.4 (lubuntu 16.04 and lubuntu 14.04) and kernel 4.8 (lubuntu 16.04.2), but it works with kernel 3.16 (lubuntu 14.04.2). after kernel update to 4.4 it doesn't work.
is this a problem with the kernel or my hardware?

is there any possibility in you bios to force hdmi as primary?
(i can clearly remeber having simular problem, and I had to do some tweaking in the bios to make thing work as expected)
you could try a bios update to se if the behavior can change..

i changed the primary graphic from pcie to onboard, but this doesn't change anything. efi is up to date.
i tried a dvi cable instead of the hdmi cable a it worked with linux mint 18 (i've tried several os from ubuntu 14.04.x to 16.04.x and mint 18). i'll try it with lubuntu 16.04 again.

hmm, sorry I could not help out there, for me this sounds like that there is some problem that when tv is off, the card does not detect any screen here, and geting confused what frecuence or picture size it should select, and the card put out a signal that your TV cant handle??. (bug?, not sure), sins the messages is 'invalid signal'.
another stupid question from me, have you try forced in xorg.conf a resolution, and frecuence the card should use under startup?
then i think about important setting like what HorizSync and Vertrefresh you tv can handle, and put those setting in the xorg.conf
