the monitor says it should support 165 hz on the display port but when i connect the display port and select 165 hz my screen doesnt enable 165 hz but goes back to 60. when i switch it to 144 my screen starts flickering and flashing turning on and off.
 
i have the aoc 24g2su the monitor had a dp cable delivered with it also im using a laptop that comes with an ryzen 7 and a rtx 3060 the laptop doesnt have a dp input/output so im using a usb c hub from i tec that should support it because with hdmi 2.0 it does on my second monitor
 
the monitor is functioning normal when its on 60hz or lower but when i go to 120 or higher it starts doing random shizzle. also i looked all over google for info but nobody had this issue
