[Q] Galaxy Note N8000 is not being recognized by Epson X14+ Projector via HDMI

Hi guys,
I would appreciate some help with this problem.
I have a Galaxy Note N8000 not being recognized by Epson X14+ projector. When I use it with HDMI adapter, it works on all TVs here at home. My Epson Projector X14+ always works with all notebooks i have tested with same hdmi cable. Always working well.
So I really cant understand this problem,, if the projector works fine with all notebooks, the hdmi cable works with all devices, the Galaxy Note works with all TVs, why my tablet is not working with the projector? The projector always says "no signal". Im using power cable at same time in adaptor like manual says.
Someone help please? I need to solve this problem to use this projector with my students while i teach. Thank you in advance,

someone please? Im very worried.

Hi Guys,
I already purchased an A/V cable for TV connecting of our Note 10.1
but after that i found that it's fit with other galaxy tabs but not for Note 10.1
so is there any way to use it instead of purchasing the MHL A/V link cable ??
thanks,
