These look fairly equal to me as far as interesting registers are concerned?
I'd guess for some reason the tmds transmitter gets misprogrammed (or
does this happen with vga connection too?) Maybe writing a register at
the wrong time or something. Could you try git head of the driver? There
were some significant changes wrt to output initialization, it may make
a difference who knows.
