Gore sam napisao, ja koristim DP kabl iz 2008.
EDIT: Naidjoh na ovo, zato meni radi sa dp 1.0 kablom
A probao sam overklokati monitor nije htio preko 75Hz, moguce da je do kabla.
DP 1.0 - 1.1a supports up to 144 Hz @ 1080p, up to 75 Hz @ 1440p
DP 1.2 - 1.2a supports up to 240 Hz @ 1080p, up to 165 Hz @ 1440p, up to 75 Hz at 2160p
DP 1.3 supports up to 240 Hz @ 1080p and 1440p, up to 120 Hz at 2160p
DP 1.4 has the same limits w/o compression but with signal compression (DSC) can do 240 Hz at 2160p
