Thinkpad P1: P1 Screen & LED TV shuts off when using HDMI output with Powerpoint in slideshow mode

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.
