I have a 240Hz, 1444p Alienware monitor, will any 1.4 dp cable work? I need a longer one or an extension.
That’s correct any DP 1.4 cable will work. I don’t now how much longer you need but Club-3D has a cable up to 20 meters it’s Active Optic (fiber) CAC-1079. Or a normal cable up to 5 meters CAC-1061. Just be sure it’s a DP 1.4 cable and also check your GFX supports DP 1.4.
