When projecting P1 screen on external LED TV over HDMI, and staring Slidehow mode in Microsoft PowerPoint, both screens dims and shuts off after a couple of mins. This happens using power is plugged in.
In Windows 10 power mode settings, screen sleep is set to 20 mins on both Battery & Power Plug-In modes.
I cannot find any settings which sets screen or HDML outputs to dim after 2 mins.
