I have a Goclever Tablet R76.2 and when I connect it to my Panasonic HDTV via a HDMI cable the screen on the tablet goes blank but displays OK on the HDTV, so whilst watching Iplayer to pause the TV programme I have to unplug the HDMI cable. I have the HDMI set to 'on' in settings on the tablet.
I was wondering if there is a way to toggle as per most laptops between displays. I emailed Goclever tech support and their reply was
"Unfortunately not this is how it works."
I saw this model on Ideal World TV and they had dual display tablet and TV at the same time.
