delstam Posted July 6, 2012 Share Posted July 6, 2012 Hello everyone! I recently installed Mac Lion 10.7 on a G41-ES2L Motherboard and I am really happy that almost everything worked without the need of further work to do. I used Kakewalk 4.1.1, which provides a DSDT for my specific motherboard. However, my Nvidia GTS 250 1GB can't output hdmi. My graphics card is recognized, I am able to see the name, brand, etc. thanks to the upgrade to 10.7.4. All of the computer components work just fine. The only thing is this graphics card.. I haven't touched the com.apple.boot.plist for what it's worth. Do you have any idea what could be causing this and how to fix this? Thank you for the assistance.

TimeWalker75a Posted July 6, 2012 Share Posted July 6, 2012 It uses a g92 gpu (pretty much 8800gtx) nested on a custom non-referece PCB board. By default this gpu does not support HDMI as it comes with dual*link dvis and s-video. You can't make it work on par with the other connector be it VGA+HDMI or DVI-HDMI. Also sound is delivered through an audio loop cable, cause the card doesn't have an onboard codec. Leave it be ir swap a card for a more recent one.
