    I've connected Avermedia AVerTV DVI Box 1080i ( to my 23" Apple Cinema HD Display. All I can see is power led flashing, which in my case means "wrong video format or an unsupported resolution" (

    I've already read those topics:�

    My TV box supports res.1920x1200 @60Hz progressive scan, what should be perfect for the display. Why does it show nothing?
    What is interesting, I can see TV box view (but only for 1 second) when I connect laptop and use PIP function. After that it switches automatically to PC's view.

    My display works perfectly with laptop (equally PC HDMI out and MAC mini-DVI out). Any ideas?

    Are you sure that your ACD supports HDCP? You might want to double check that, it could be the problem.

    Otherwise I suspect it is somehow not giving it the right resolution, despite what you say.

    ACD is not HDCP compliant but the signal from TV Box is not HDCP protected so it's not the problem.
    Thanks for the suggestion about resolution ...I double checked and it works. I still can't use PIP or PREVIEW functions and I thinks the reason is the same but I think you can really do nothing about it.
    Supported resolutions:
    ACD: 1920x1200, 1280x800, 1024x640.
    TV Box: -fullscreen view: 1920x1200, 1680x1050, 1600x1200, 1440x900, 1360x768, 1280x1024, 1280x768, 1024x768; -PIP view: 1680x1050, 1600x1200, 1440x900, 1360x768, 1280x1024, 1280x768, 1024x768.
