I just got an RTX 2070 XC ultra gaming graphics card and once i installed it and got all my drivers up to date, i tried setting my refresh rate to 144hz like i always had with my past graphics card (GTX 1070 SC) but for some reason it wont let me change the refresh rate, the only option i have is 60hz and i went out and bought a new 1.3 HDMI chord, that didnt work so i returned the HDMI chord and bought an HDMI to DVI-D converter and it still does not work. i checked to see if my monitor had any driver updates but it is up to date and i dont know what else to do? any help would be appreciated.
