Default Re: No hdmi video on Asus AT3N7A-I with versions newer than 195.36.31

I'd suggest installing both a failing/working driver, and running on each:

X -logverbose 6

That should spew a bunch of mode validation data into /var/log/Xorg.0.log. Perhaps there will be some obvious difference there; post them here, and we can take a look too.

Finally, if you can ssh into the system while there's no display, you could try running:

DISPLAY=:1 nvidia-settings -c :0

(Replace :1 with your SSH forwarded X display name)

and that'll fiddle with your main X server's display yet display on your client machine.

Then, go to the page for your monitor, and try tweaking the GPU scaling options, or even the X Server Display Configuration and see if you can find a mode that works.
