    Aloha Community.

    I hope this is the correct subsection.

    I want to create a virtual monitor on my osx 10.9.2

    Point is I want to use an old notebook (Linux) as an additional monitor.

    I tried screenrecycler but it is really slow since it uses vnc.

    There is a hack some people used to trick their Mac mini into thinking a monitor is connected by doing a mod at the VGA port with resistors. This works well but since my graphicscard is an older nvidia it just supports 2 real monitors at a time and two are already connected.

    My setup right now is the following:

    I run both air server and airparrot on my machine an connect airparrot as extended desktop to air server. This way I get a virtual monitor. I minimize the air server window. Then I use nomachine for screen sharing to get the virtual monitor shown at the notebook. Since they are connected via 1 gbit LAN, performance and quality is good.

    Issue is that I can't set a other resolution than 720p and 1080p.

    What is really want is 1600x900.

    I tried switchResX, but since the virtual monitor is not recognized I can't add custom resolutions.

    So I am looking for a way to either change the air server "screen" to 1600x900 or even better create a virtual screen with the desired resolution without using the hack using airserver and airparrot.

    Any ideas?

    If i am correct, Quartz is the osx pendant to X11 in Linux. In Linux I can create a new monitor using a dummy driver and just add the screen with desired resolution, position, depth and is to the xorg.conf. How do I do that in osx?
