I am working my Diploma Thesis on 3D Rendering Effects using FPGA and I am facing a problem which may be known to someone.
I was using a Nexys4 board with VGA output and everything was good with the video output on screen. Here are the signals from top level component in Nexys.
entity TopLevel is
CLOCK : in STD_LOGIC;
RESET : in STD_LOGIC;
DOUT : out STD_LOGIC_VECTOR(11 downto 0);
HS : out STD_LOGIC;
VS : out STD_LOGIC
Because my implementation is huge, I took a larger Board, Kintex7 KC705 (xc7k325t). Now, I have to integrate the implementation to HDMI output because there is no VGA output here. The XDC for KC705 says that these are the output signals for HDMI.
OUT: HDMI_D17 - HDMI_D0, HDMI_DE, HDMI_CLK, HDMI_VSYNC, HDMI_HSY
I have found a possible solution here http://hamsterworks.co.nz/mediawiki/index.php
Could you plesase help me to in order to have output on screen or attach me a test project? After seeing an image on screen, then my life will be easier to continue my thesis project, as I have already implemented the whole 3D Rendering Pipeline in VHDL.I
I would appreciate any respond! Thanks in advance.

Thanks for the quick answer. I do not use microblaze in my implentation. So you suggest me to use a core to transmit my signals.
The HDMI_DATA signal is 18bit as the xdc refers and I have never seen such number of bits in color signal. I think I want a component which takes my CLOCK, DATA, VSYNC and HSYNC signals I had for VGA and give me outputs the HDMI_DATA(17 DOWNTO 0), HDMI_DE, HDMI_CLOCK, HDMI_VSYNC and HDMI_HSYNC signals. Or something like that?

Is there a way to use the HDMI without a processor on KC705?
