so i got this 144hz acer predator monitor and i got a vga cable, now i know that it didnt work with that cable so i bought a dvi-d cable. I can chose 144hz aswell as 120 and 100, but when i do it says incorrect cable please use the dvi dual link cable that came with your monitor... i guess i should try to get a displayport cable?, i know my monitor supports it but i dont know if my pc does... should i get displayport to dvi-d?
