Windows 7 - Display 'A' Philips primary display - Display 'B' IBM secondary display.  A shows as Identity 2 and B shows as Identity 1.  I want to reverse these.  Reason is that the cursor currently travels from display B to A and I need it to go the other way - due to physical location of displays

In the Screen Resolution window, under Change the appearance of your displays , click and drag one of the monitors to its correct location vs. the other one.   The Identity numbers don't matter.

    Thanks, Mobius Pizza.  

    On their product page here:

    http://www.gefen.com/kvm/ext-dp-edidp.jsp?prod\_id=10909

    Under features, it says:

    "Supports 1080p Full HD at 120Hz and dual-link resolutions up to 2560 x 1600 (WQXGA)"

    This would just barely be enough resolution in my case.   I have two side-by-side 30" monitors with 2560x1600 resolution on each.   So I'd have to get two of these, at $549 a pop, for  a total of $1098 to solve the problem.

    It used to cost $28 with VGA:

    Now that everything's digital it costs 20x as much.   I hope it gets cheaper but I'm not holding my breath.

    And if I get a 4k monitor, it will no longer work.

    What's needed is piece of hardware that will emulate the existence of the monitor (or Occulus Rift in StevenMartin00's case) when the monitor is not plugged in.

    StevenMartin00:

    Try an HDMI EDID emulator for your Occulus Rift:

    http://www.bhphotovideo.com/c/buy/edid-emulators/ci/25916/N/3871319890

    In the old days, I used to use a VGA EDIA emulator:

    http://www.bhphotovideo.com/c/product/1077834-REG/apantac\_dvi\_e\_edid\_emulator.html

    For each monitor, I'd keep one of these plugged in between the cable and computer.  It would fool the computer into thinking there was still a monitor connected and I could unplug and re-plug monitors with impunity and the computer would never know.  Notice it only costs $28.

    What's needed is a "displayport EDID emulator" that supports 4K resolution at a reasonable price.

    Gefen makes this one for $549 but it only supports HD resolution.  No good for computers:

    http://www.bhphotovideo.com/c/product/1029265-REG/gefen\_ext\_dp\_edidp\_displayport\_detective.html

    I have 2 3k monitors on my computer so I would need two of them.  Even if the resolution were supported, I would not pay $1100 for 2 of them.

    So I don't think we're there yet, but hopefully this will be coming soon.
