I recently bought a Android Qbox off Ebay that has the S905 quad-core cortex-A53 with the Mali 450 5 core GPU. I tried streaming 1080p movies through Exodus and it seems a bit choppy and not as smooth as I was expecting. I tried changing to the HDMI sync to ON and it seems to work better on some movies. My question is there a setting to fix this? I'm using a 55" LG 4k tv to watch. Do you guys think this a hardware issue or software? Should I upgrade to the Beelink GT1 with the 8 CPU and Mali820?
