    Minimal HDMI connection pins , only 8 pins is enough ??

    Dear Gurus , tell me whats wrong ?

    0) I try to use Mike Fields tutorial http://hamsterworks.co.nz/mediawiki/...p/Minimal_HDMI ,I use only positive and negative clock, tmds 2, 1, 0 four pairs (8 pins) out and thats ok to have a video ? or other pins must be connected ?

    1) use 2.5V fpga bank, with ( IOSTANDARD = DIFF_SSTL2_II_DCI ) Mike Field used Spartan 6, i use Virtex4 so i have not same IOSTANDARD feautures in constraint file.

    2) and ODD instead ODD2 .

    Hi,

    Additionally you need at least GND.

    I'm not sure: Isn't HDMI using LVDS signals?
