i've assembled my diy dvi to hdmi cable, this is the best i can do (pictures), the hdmi cable i used seems like the cheapo one since data shields and any grounds are connected to one single wire (chassis), so i have to connect all DVI shields into one and connect to there. but it seems to work, i managed to setup my Z800, but i have problem with quadro 4000 driver in Win7Pro 32 bit, so i can only test 800 x 600 resolution meh. i dont think its likely the driver installation problem has to do with my diy conversion right?

next is i have to order writeable DVD greater than 5GB to burn Win7Pro 64bit ISO in it and try 64 bit installation, i hope quadro 4000 is ok there. i only have 4.7GB DVDRW which 64bit ISO installation cannot fit bummer. my plethora of adapters ordered earlier is 1-2 days away now.

It's likely you screwed up the DDC wiring.

i checked and rechecked for continuity and short, everything seems fine, i'll check back again if its really matters. how can DDC problem will make 4000 driver crashed in Win7? earlier version gave me BSOD, later version gave me abysimal 4 bit color, but Windows default driver seems producing better color as you can see in the last picture above.

You didn't say it was crashing, you just said you couldn't get a proper resolution out of it..

well the driver installation is not so straight forward, i disabled 4000 driver in windows, reinstall ver 341.44, and it reported 3d vision driver or something that was installed earlier is not compatible, it removed it and now the quadro 4000 display is working yay. there some sort of ghosting, thin horizontal brighter line projecting from each windows edge (i cant get it in camera) but for me its not so serious. i'm not sure if its the cable's signal integrity traits, or my aging samsung tv monitor. but as always, "TV" monitor sucks at reading text anyway, this time is only to setup the Z800 while waiting for proper adapter for proper VGA "PC" monitor connection. so this diy is possible (i dont say its ideal), even on a budget cable. no need factory termination :P
