To ATI DVI M series
This adapter will only work with specific ATI video cards and the only if you have the specific ATI Catalyst drivers. See the details on ATI’s site here: [...] They also have a manual for this adapter on the website.
The reason it doesn’t work with just any DVI-I output is because TVs use a sync-on-luminance signal ([...]), which only certain video cards support. I have an ATI Radeon 4350 so I assumed it would work, but unfortunately this card does not support the sync on luminance so the adapter couldn’t do it.
