DVI to HDMI

by sgjennin / September 22, 2009 11:07 PM PDT

I picked up a DVI to HDMI cable at the Apple store to connect my 2008 MacBook Pro laptop running 10.6.1 to a Samsung SyncMaster T240HD. I plugged the DVI into the laptop and the HDMI into the monitor; the laptop recognized the monitor and allowed me to set the res to 1080p for it, but the monitor gave me a 'no input' signal. I tried mirroring on and off, but nothing. I tried each input setting on the monitor as well. Any ideas?

This didn't work for me either. I had to get a DP to DVI cable then a DVI to HDMI cable; then everything worked fine.

You have to ensure that the cables are HDCP encryption compatible. Many newer tv's have this to ensure that users cannot capture high def content in a similar way the analog loop allowed. Although, I am sure most of the cables sold by the apple store are compatible with this level of encryption. I'm a little confused as to what could have gone wrong.

However as the other user said, using a dual link to a dvi to an hdmi connection might allow for a bypass to this encryption. Not sure if that is what is happening but it does explain the issue.

Use 1080i

Your graphics card does not support the higher refresh rate of 1080p. Select 1080i instead. It's the same resolution, but 1080p doubles the refresh rate. Encountered the same issue with my 2009 MacBook Pro which has 2 video board options. The more robust can run 1080i but can't step up to the higher refresh rate

Cheers !
