I need two genlocked outputs from a single video card. Can anyone tell me on which, if any, AMD cards the outputs will be genlocked?
Googling suggests "genlocked" can mean synched to an external source. I don't need that, I just want the two outputs to be synchronised to each other, "frame-locked".
And if its relevant I can use the card under either Linux or Windows and the graphics will be generated using OpenGL.
I think you are misunderstanding the concept of FL/GL. You should explain your problem or say what you are trying to do, then I might be able to help you.
I want the buffer to flip simultaneously on two monitors, each one connected to the a different DisplayPort on the same card.
And this doesn't work?
FL/GL is only used:
Outputs from one GPU are always synched
VGA outputs from the same GPU did not used to be synched so that's a welcome change.
VGA is analog and history
