So I just bought this monitor and am excited to start using 120Hz (and supposedly 240Hz). However being a noob totally forgot to check if my graphics card had the right display ports. It came with a Display Port cable but my 7970 doesn't have the necessary port for it. Can I just get an Display Port to HDMI adapter and expect no problems or have I gone and blown £££ on a monitor I can't take advantage of? Thanks.
