I recentrly bought a new Macbook Pro (the one with thunderbolt port) and this mini displayport to DVI/HDMI adapter: http://www.dealextreme.com/p/3-in-1-mini-displayport-male-to-hdmi-displayport-dvi-female-adapter-37374 Problem is that it doesn't work. I have a HP x22 monitor and when I plug the whole thing into the macbook I get "Input type not supported" on my monitor. The display is detected as HP x22 and the correct resolution is selected (other resolutions don't work). I tried the adapter on another display - the same thing. Then I tried it on a TV with HDMI-HDMI cable and this worked correctly. So I went and tried HDMI to DVI cable and this didn't work. So HDMI to HDMI works but I can't connect a DVI monitor. Any ideas?
