What happens if you connect a VGA and HDMI display at the same time to a recorder?

For V7 and V8 reorders, both screens will just have a similar display. This is a mirrored display on both screens rather than an extended display.
Keep in mind that the resolution set on the recorder should be compatible on each display to achieve this; otherwise, one display might not show anything or may give you an error message such as Fixing “No Signal”, “Video Mode Not Supported”, or Blank Screen on Recorders.
NOTE: The use of video splicers is NOT recommended nor supported for extended display.
