2006 Mac Mini only works with DVI-VGA adapter

[Mormislaw]

Hello,
I have an issue with my C2D-upgraded late 2006 Mac Mini - image displays correctly only using a DVI to VGA adapter, if I use DVI-D I get a screen like this:

What could be the issue? Has anyone fixed this problem?
I'd appreciate any help.
Thanks in advance

Silly question, but have you tried another DVI cable?

Yes, same results sadly

Maybe try a different monitor.

Does it make a difference that the port on the Mini is DVI-I?

Probably a damaged connector resulting in a pin or two failing to contact sufficiently. The signal pins for a DVI-D signal are slightly different from VGA (aka DVI-A), and I expect the pins that are shared have a greater tolerance. A poor connection on VGA (analog) will just get you a blurrier picture,
