Our main issue is that we bought a bunch of QM B-series displays which does not seem to have the Daisy chain option with either DP or HDMI as an output. We are looking into the service menu ( mute + 182 "power on"), and under "Control" - "LFD Option" - "HDMI Tx Test" we are able to select a source as a loopout input, and also choose a port as a "HDMI Loopout Test". However, we does not seem to make it work.
Does anyone know if the hdmi loopout functionality is available at all in the B-series, and if so, have any idea on what settings we should adjust?
Also, does anyone has access to a guide to the service menu?
