View Full Version : Powerbook G4 12" - MINI DVI to HDMI

I have a Powerbook G4 12" (2005) and want to use my flat screen TV as a large monitor to play back downloaded movies.

This new TV has HDMI ports and I have connected it to the laptop with a Mini DVI to HDMI cable. (This used to work on the old TV using Mini DVI to AV cable but there are no spare AV ports on the new TV)

Disappointingly though the laptop picture is not repeated on the new TV. Is there a trick I am missing here or will such an old Powerbook just not support HDMI?

Any solutions gratefully received.

Depends on what you mean by downloaded movies. I don't believe mini DVI supports HDCP (copy protection scheme), so you may be blocked from playing movies through that connection.

Thank you for getting back to me.

In fact the problem seems more fundamental than that as the TV won't even repeat the laptop's desktop image - so I haven't even got to the movie watching stage yet! The TV simply shows a default Apple image (Nature - exploding star in space) rather than the family photo I have selected; in addition none of the icons or menu bar are displayed.

It seems you have Extended desktop enabled mode by default. And it's good, because in mirroring mode your TV would use PB screen resolution. To use TV as main display in extended mode, just drag menu bar on it in display preference pane.
