The Wechip remote control works on all aspects of the Beelink GT-King with the exception of powering it on.
It will power it off if you place the air mouse arrow over the OFF icon which is on the lower left of the main screen of the GT-King. I'm not sure as to why my posts are being moderated and excepted from posting ?
I would greatly appreciate any remote with a number pad that Beelink could provide as an optional accessory even if it came as an accessory item with a cost. Please notify me if one becomes available.
It seems like there might be a compatibility issue between your LG TV remote and the TV Box. One solution could be to try using a universal remote that is compatible with both the TV and the TV Box.
