4K 60Hz TV stuck at 30 hz

Hello, I recently bought a prebuilt CyberPower PC with an RX 580 and out of the box my Sceptre U40 4K TV is being seen as only supporting 3840 x 2160 30Hz. I can't lower the resolution to 1080p or raise the refresh rate to 60Hz without getting an "unsupported by your display error" in Radeon custom resolution settings. I'm using the HDMI 2.0 cable that came with my Xbox One S and 4K 60 works fine on that.

Please help.
