You can also use one output channel of the iR for driving the HMD.
We are using this method to do stereo on a nVision Hi-Res HMD with
a resolution of 1280x1024. The advantage is that there is no vertical
or horizontal delay between the two channels. When using the iR outputs as a
MCO the horizontal phase shift can be up to several lines.

there is a page describing Stereo Field Sequential using a Infinite
Reality.
