I have a Mini PC (Intel Celeron NUC), it has HDMI output. I use on a Projector to play videos in a school.
last week, i got no image at all on the projector with HDMI. (not even bios/boot screen, so its NOT a driver/windows issue - the boot image appeared before this problem) tested projector with a notebook, projector is fine. tried another HDMI cables with the MiniPC, no image at all. tried MiniPC with a LCD TV, also no image at all.
at home, tried with a HDMI > VGA converter, (to keep testing the HDMI port) also did not work at all (this converter worked previously with this MiniPC). reseted bios, checked contacts (pins are fine). nada.
so i thought, "the HDMI output is gone". but no. if i connect it with a HDMI cable and a HDMI to DVI adapter on a DVI monitor, BAM, works fine. resolutions/monitor is detected, everything fine.
i thought something different with DVI/HDMI may be the cause, so i tested the 5V and HotPlug pins on the HDMI, they show 5v as they should.
so... my question... what can cause this this?
um clueless.. i asked in other forums, and got no response... you guys are my last hope...
