Re: HDMI is unreliable with nvidia optimus on asus n53sv



Obviously I have no single best solution for you, but I can tell you what my experience is with my n53sv. I used Linux Mint with IronHide connected to a LGTV via HDMI and I never had any display issues. I did have some issues with sound over HDMI, but that is another story. I also connected the laptop to 2 projectors (one via HDMI, the other via VGA) and that too worked together with Compiz. That was about half a year ago. Soon I will try it with the latest LMDE and will post any necessary workarounds to make it work (should any be needed, and if I manage to find them :-P).

Best Regards,

Michal Biskup

If a HDMI display is plugged in, it can work, but mostly does not.
If a sony monitor is plugged in immediately after the grub menu, then the monitor displays either on boot
or after a disconnect/reconnect/redisplay cycle.
A panasonic plasma TV did work, once, but now does not.

HDMI displays are always detected by the software, either xrandr or settings/displays, when activated, with correct resolutions
in displays.

Any ideas on this welcome,
