Using AOC U3477PQU but Can just get 29hz ?

[Macmomomo]

I got a Mac Pro late 2013 with a AOC 34" but can not get more than 29hz. I am using DP connection.

What am I doing wrong ?


U3477:

RES: 3440 x 1440 @ 29 Hz

depth: 32-bits farge (ARGB8888)

Mainscreen: Yes

Same screen: OFF

Connected: Yes

Connection type: DisplayPort

TV: yes ???? Why is this on ? and what does it "do" ?

thanks for the support site, I did found out that I had it on 1.1 DP on the screen, switched it to 1.2 DP and everything went smooth.
