Hey guys. Most people and bussinesses assume anything over 60Hz is useless when trying to use an R9 290x, but that's wrong. League of Legends is a good/good looking game that Im 100% sure the card can handle on 4K. The cable type/port supports 75Hz, but the card is limiting me to 60Hz. I see this cap in game and on my adapter settings in Windows. How do I get 75FPS? Thanks
