Just quick question!.. I've been looking everywhere on google and can't find specifics to the above question!?. Can my R9 280X or any R9 series GPU for that matter output 4K on the HDMI port?.. If it does, is it limited to 30Hz?.. If that is the case then I should be okay going with that BUSH 4K TV and use it as a secondary video player for YouTube and other streaming media and maybe possibly some 1080p gaming on the XBOX 360 & PS3... Thanks!..
