HDMI to DVI dummy plug

Postby MarkJohnson » Wed Feb 25, 2009 2:25 am

I have a GTX 295 and can't get the second GPU to fold. I tried doing an HDMI to DVI plugged into a DVI to VGA with 68ohm resisters and it won't detect it. I had to modifify the DVI to VGA pins so it would connect to the HDMI to DVI, but it doesn't register.

I was hoping someone had a dummy plug for the HDMI to DVI in hopes that would do the trick.

Use an hdmi switch box, or try higher ohm resistors. I have read suggestions of 75 ohm min on some different sites, I did mine with 100 ohm because my radioshack doesn't carry 75 ohm by themselves, only in a variety pack with like 2x 75's in them; hardly worth it.

Actually on second thought, HDMI does not send an analog signal, so the DVI-VGA adapter has nothing to send to the 'monitor' that the resistors provide. DVI-VGA adapters simply take the analog signal that can be output from a DVI source and moves the data pins to where they are in VGA plugs. HDMI also has copy protection so this may get in your way further.

This probably will not work. You will need to have the HDMI go to either a display or something that the computer thinks is a display like a switch box.
