Question about Roline DisplayPort — DisplayPort

After reading the comments of the users before, i would pass this one and check for another cable, to get the whole 144Hz @ 1440p!

Lindy DisplayPort (2m, Midrange)

Here i see a review from another user, where he says, that he was successfully tested it also with 1440p / 144Hz.
I would go for this one.

Your display scource just needs DPPort 1.2, if that's the case it sould worke all fine.
