I have a 2006 macbook pro with DVI out. I use a dvi-hdmi converter to watch stuff on my epson projector. I haven't had a problem in six years until this week. HDMI monitors are no longer detected by my computer. DVI to vga works fine. Tried resetting PRAM, system memory, & deleting preference files per other discussions. Nothing in my setup has changed. What the ****?
MacBook Pro, Mac OS X (10.6.8), VGA monitor still works
I just wanted to add that I have troubleshot every part using 2 projectors and muliple cables and adaptors. I also ran the extended Apple Hardware Test which came up clean. The DVI out also sends power to my HDMI switcher. This has to be a software issue.
Ok. Reinstalled snow leopard. Computer now responds when I plug in dvi cable. Goes to blue screen like it is going to switch resolutions & work, I get all excited, and it comes back to normal resolution with no video output to projector. Fail but a small step in the right direction. I am installing original 10.4 disk that came with the computer. Nuke everything & start over. I used to love you zealously apple. What happened? Can you give me reason to believe once again?
Macbook Pro DVI / HDMI display no longer recognized. VGA works fine.
