separate video output on hdmi and rca

[ric96]

is it possible to have a dual monitor setup with hdmi and rca having a monitor each??

No.

HDMI and RCA share the same Pixel Valve (a hardware unit that is responsible for taking lines of memory and turning them into streaming pixels of the correct colour depth/bit width at the correct rate) thus both cannot be active at once. Unless you're content with just auto-generated test patterns on either HDMI or RCA, of course.

(HDMI ^ RCA) and DPI (on B+/A+/2B) and DSI do not share pixel valves, so in theory you can have those interfaces all active at the same time.

So to have a dual display setup i would need the upcoming DSI display?

Or the Gert VGA666 unit, which takes up (almost) all of the GPIO pins and allows a VGA screen to be connected as well as the HDMI or Composite output.
