Hm, I bought this cable today, so I'd think it should be ok --- but I didn't explicitly specify that it must be one that does 4k@60. I didn't know I might have to. Is there any way to tell? The sticker on the package only says DP/DP 2.0m. > But if you use the cable that is delivered with your monitor, it > should work for all resolutions/refresh rates as long as it is not > broken. Unfortunately, the cable that came with it has a normal size connector on one end and a small size connector on the other. Both the monitor and the graphics card require the normal size connector, so I cannot use that cable. That's why I bought one ... > Sorry, but I can't say anything about the rest of your questions. Np; when I don't have the right cable, it'll never work anyway. Now I know what I need to look into first :) -- Again we must be afraid of speaking of daemons for fear that daemons might swallow us.
