[jitter] Re: AJA digital video output

A few issues here.

1) the AJA cards do not have accelerated graphics. For anything BUT regular CPU (jit.matrix) based image processing this is going to be SLOW, even for window drawing and display updates.

2) THE SDI signal output is uncompressed 4:2:2 YUV standard def, so, unless you are driving your display via analog SD like composite or S-VIDEO, vga or SVI will, technically, be higher quality uncompressed 4:4:4 signals. You *may* be loosing quality, and you will most likely be loosing resolution.

3) If you REALLY want to do that, you need to make sure in the AJA control panel that you have 'Monitor/Desktop' enabled in the control section. If you are using the latest 5.1ND drivers this is disabled, and you have to download 5.1 vanilla, but the ND (no desktop) drivers fixes some issues that people were reporting with desktop video out.

Once you have that enabled, you should be good to go, as it treats the AJAs output like another monitor. 

Good luck.
