LG Ultrawide Monitor not showing full resolution in Windows. Only shows 1920x1080 not 256x1080 fix

I picked up this monitor on offerUp. When I fist plugged it in I didn't have have the option under display setting to go into full 2560x1080. I only had the option for 1920x1080. To get the higher resolution you need a higher bandwidth cable. Preferably with no cable breaks
