Samsung Odyssey G5 34′ 165Hz DisplayPort problem.

Hello guys,

My monitor won’t power on DisplayPort, the blue power keeps blinking.
It works fine on HDMI, but it shows only 60Hz.
I’ve tried to disconnect the power chord and everything then turned it on, I’ve tried 2 display ports, same problem :/

Btw when I connect my Displayport, I press the menu on the monitor and it shows 165Hz, but it shows nothing, black screen and the blue power keeps blinking.
But when I switch it to HDMI it shows 100Hz only.
