I'm wondering if its possible to play 4k videos directly off the micro SD card in a Nvidia Shield K1. I tried today and when I went to open the file it said it cannot open file. Only been flying my P3 for a day so I'm still learning. My end goal is to be able to plug the Shield into a 4k TV via HDMI cable and play the video on the TV from the tablet. Any insight would be appreciated..or other work arounds.
