I'm trying to work a deal between my Key Digital iSync PRO and Optoma HD73 so that an RGB signal can be sent over HDMI. Of course, sending component YPbPr works just fine.

Generally, when I switch the Optoma to the RGB color space - all I ever get is a very bright green screen - whether I'm sending component YPbPr, or presumably RGB over HDMI from the iSync.

I have noticed that I need to turn the iSync PRO off and on after setting the HDMI out CSC to 'RGB'.

Is anyone successfully using their iSync PRO in this mode - and if so - can you tell me what components you are using and if there was any trick to get it to work?
