Tablet battery power - affected by HDMI-VGA monitor connection? Answered
I have a 7" Windows 8.1 tablet running a music (MIDI/VST) program to provide sounds via the audio output. Input is via an OTG microUSB cable connected to a USB MIDI 'mini' keyboard (Akai LPK25 - USB powered). The audio is connected to Line In of a Yamaha Tyros keyboard and it works. I intend connecting a VGA monitor to the micro HDMI tablet port (microUSB to VGA adapter and VGA cable) and would like to know if there will be increased draw on the battery.
Is there a way to supplement the power to the tablet as the charger uses the same microUSB port?
