Roku Ultra streaming device (you tube ) does not out put to 4k or 2160p when connected to VAVA 4k HDCP 2.2 HDMI 2.0. UST projector, All videos are maxed at 1080P. The description says the Roku ultra is capable. When I go in setting , all I have is Max 1080p or Auto. Noe IF I use same HDMI wire connection with Sony UBp-X800M 4k blue ray player (has You tube App), My VAVA projector is showing 2160P. That tells me Roku is not outputting to 2160p.. On both instance its the same video file (2160P).
