[tadpol387]

Hi Bros,

My monitor flickers whenever i adjust my monitor refresh rate pass 60hertz.

Details are as follows;

Monitor - PRISM+ F270i PRO

Graphic Card - Powercolor Red Devil Radeon™ RX 5700XT 8GB GDDR6 Graphics Card

Cable - UGREEN DisplayPort 1.4 Cable 8K 4K HDR 165Hz 60Hz Display Port Adapter For Video PC Laptop TV DP 1.4 1.2 Display Port 1.2 Cable

Quite sian that I can't utilise the 144hertz capability because of this.

Your help would greatly be appreciated.

Kindly advise.

Thanks you.

From my experience, it’s DisplayPort cable issue. Try changing a cable. Had the same issue with my Alienware 3418

I had the same issue before.. few options for you to try before spending money on new cable..
1. Power cycle the monitor, unplug everything from monitor, until all power discharged, then plug in again and see if it's working now.
2. After trying 1, repeat but use a different DP port.
3. Uninstall display driver with DDU and install latest drivers.

If all else fails, buy a proper VESA certified cable.. UGREEN is not certified according to this database https://www.displayport.org/product-category/cables-adaptors/

Also no need to try with HDMI cable, HDMI doesn't support 1440p 144Hz

EDIT: is this the cable you bought? https://www.ugreen.com/product/4k_displayport_male_to_male_cable_1m-en.html
According to the specs it only support 1440p 60Hz

If it flickers every xx seconds, probably due to bad capacitors if the above suggestion fails.

Actually it depends lah. Maybe the OEM of his cable got VESA certified but if they don't reveal we won't know. A 100% VESA certified HRB3 DP 1.4 cable is around 23 so not too far off.
