## Remarks

Generally, call this function only when the front panel display needs to be updated. Calling it for every frame is needed only for animation.

To get the pixel format to use in *buffer*, use [XFrontPanelGetScreenPixelFormat](/reference/devkit/xfrontpaneldisplay/functions/xfrontpanelgetscreenpixelformat).

To get the dimensions of the front panel display, use [XFrontPanelGetScreenDimensions](/reference/devkit/xfrontpaneldisplay/functions/xfrontpanelgetscreendimensions).
