Currently using a Dahua NVR5416-4KS2 and trying to output 4 camera view via Hdmi output at 1080, the only way I seem to be able to do this at the moment is with the tour option set to refresh every 2 minutes, this means I get a flash then the 4 camera view appears again after 2 minutes. Surely there must be an option to output 4/9/16 or more camera views via the Hdmi for monitoring purposes rather than using the tour option, most likely me missing the obvious but would appreciate anyone who has experience with this setup. Thanks in advance.
