Question Trying to unlock 144hz on ASUS PG248Q

[ValorUnlimited]

Hello,

I recently bought an ASUS ROG PG248Q 144hz gaming monitor on ebay and added it to my existing dual monitor setup. The other two are an ASUS PB238Q and a VH236H. They are both 60 hz monitors. The PB238Q is connected via HDMI and the VH236H is connected by DVI. The PG248Q is connected by DisplayPort. They are all connected to the same EVGA GTX 1070 running on a 650W EVGA power supply.

I have tried the following things:

Setting my Advanced Graphics Settings to 144HZ in Windows.
Setting my Monitor's Refresh Rate to 144HZ in NVidia Control Panel
Playing in fullscreen and borderless window mode.
Turning off Vsync both in Nvidia Control Panel and in Borderlands 2, Far Cry 5 as well as Witcher 3.
Moving the frame rate limiter slider in above listed games to unlimited.
Disabling both other monitors and playing with a single 144hz monitor from NVidia Control Panel.
Enabling overclocking in the PG248Q's menus and manually setting the monitor to 180 fps.

All three games show a rock solid 59-60 fps at all times upon exiting the menu.

What am I missing here?

Addendum: Attempting to hit 144hz in all three games at native 1920x1080 resolution.
