Hi,
I purchased the above tablet a few months ago and just got round to connecting the tablets hdmi port to my tv, all is good until I connect the charger, then the hdmi goes off, any ideas. I can use chromecast still, but wondered about this problem/feature.
Thanks

It might be easier to provide some assistance if you were to identify the tablet. The specifications you listed could fit many different tablets.
