Trouble outputting 4K 60Hz (via AMD R9 280X)

I'm trying to get my PC to output at 4K 60Hz but I can only get 4K at 30HZ. 1080p is the highest that I can output at 60Hz. Here is connection

Sapphire R9 280X > Outputs to: Display Port 1.2 DP-to-HDMI 2.0 converter > Outputs to: HDMI 2.0 Cable to TV

I've tested the TV with another device via the same HDMI cable and achieved 4K and 60Hz (laptop with an Nvidia gpu).

AMD is reporting a max resolution of 4096 x 2160 and max refresh rate of 60 Hz
However, Windows Screen Resolution only lets me apply 4096 x 2160 @ 24Hz or 3840 x 2160 @ 30 Hz.

Any idea about what the issue may be?

Best guess is that converter doesn't actually support HDMI 2.0 as output.

^ This, or the TV is not HDMI 2.0

On most 4K TVs, only 1 or a select few HDMI ports are actually 2.0, supporting 4K Input.
The rest will be older specs.

4096 x 2160 @ 24Hz or 3840 x 2160 @ 30 Hz
^ This can be correct. Most 4K TVs will not be 60Hz +
