Default Xv Sync to Device environment variable??

With OpenGL video rendering there are 2 environment variables I use to control vsync on a Twinview setup:

__GL_SYNC_TO_VBLANK=1
__GL_SYNC_DISPLAY_DEVICE="TV-0"

With Xvideo rendering I know there is a variable "XV_SYNC_TO_VBLANK=1", but what is the variable to specify the device?? There is a setting for it in nvidia-settings GUI, so I assume there must be an environment variable as well. Thanks.
