144Hz monitor only getting 60Hz with displayport cable

[lukas.jankauskas963]

I just bought 144Hz monitor (Samsung C27FG73FQU) andwhen I connect it with displauport to my Radeon RX580 graphics card I only get option to select up to 60Hz with 1080p. When I connect with HDMI, I get option for up to 120Hz, and this is normal, because monitor has only HDMI 1.4, which is capable of only 120Hz. What should I do to get full 144Hz on my monitor through displayport?

I'm using windows 10.

I already tried Display settings>Display adapter properties>List all models OR Monitor tab, there is only up to 60Hz option.

Have you try changing your DisplayPort version in your monitor from 1.1 to 1.2?

See page 41 of your manual: http://downloadcenter.samsung.com/content/UM/201705/20170509143810667/BN46-00682A-Eng.pdf

Display Port Ver.

Select your Displayport.
―Incorrect settings may cause the screen to go blank. If this occurs, check the device specifications.
―If the monitor (when set to HDMI1, HDMI2 or DisplayPort) is in power saving mode or is displaying the message Check Signal Cable or power saving mode activates, press the JOG button to display the function-button screen and then select the button to display the On Screen Display (OSD). You can select 1.1 or 1.2.
―If setting the DisplayPort Ver. to 1.1, for the bandwidth limitation of the DisplayPort 1.1 protocol, the actual maximum output refreshing rate of the display cards cannot achieve the level of 120 Hz/144 Hz.

Yes I tried this, didn't help :/

EDIT: nevermind, it helped. Tried after changing to DP 1.1 turning monitor off the power supply and it helpped
