2to1 VGA multiplexer to make DDC stereo adapter
Posted: Tue Feb 09, 2010 6:28 am
Hi
I'm investigating the possebility of making a adapter with two VGA inputs whcih multiplexes these on one output with a DDC stereo control signal which then can be used with shutter-/head mounted displays.
My big question, before I do too much effort, is if anyone knows if the VSYNC (frame update) between two monitor outputs on the GPU are in sync when the refresh rate is set equal, or not?
