Hello! I have 3pcs of Zgemma H8.2 , All of them have buggy picture in 1080P ... So you are not alone!
if you "plays" with the remote control, Take up the channel list fast, and close it fast.. and takes it up fasat again, and so on, You can see a "ghost image" on the screen for about 0.5 seconds in the middle of screen / bottom of screen (i think...), :=) -- Some times.. Its good... I have also try different TV's, HDMI Cables, and so on, but its the same with them all , 1080I seems to work also 720P
And I have notices thats it have to be a SD channel its almost happens, but some times it also happens on HD channels ..??
I Have not seen this errors you uploaded pictures on! , I Checked again, and they are not there for me
