On my M18XR2, with a 880M, Windows 7, modified BIOS and modified nvidia driver, the HDMI In seems not working.
When I plug a device, power it on, nothing happen on the screen, and when I press Fn + F8 (HDMI IN), I got a please connect HDMI Input Device message.
Do you have an idea how can I enable this fonctionality ?
Maybe in BIOS ?
Thank you !
