I'll get right to it. I recently bought a 4K monitor (as stated above) and my fps has been dropping. My resolution is 3480x 2160. I played league of legends ( MOBA) and my max fps is 30 whenever i use vsync. If i disable it my fps goes to ~200. I know that my Radeon 290x 4gb can handle it but why is my fps capped at 30? Even if i disable vsync there is no difference becuase the I think the monitors max refresh rate is 30 (Really?). Thank you if you can help me.

I use HDMI but it says 60Hz for refresh rate. There are only 2 HDMI and 1 Displayport on it. Does it mean that only display port supports 60hz at 4k and HDMI doesnt? o_O
