No USB option on input menu Acer Nitro XV272UP
So first time getting a pc and decided to get a Acer Nitro XV272UP, the pc tower has 2 USB 2.0 ports and 1 USB 3.0 port, the 2 2.0 ports are being used by mouse and keyboard, so that leaves the 3.0 open for the monitor, and i assumed so as the computer came with a blue USB, so as far as i know thats a 3.0. I plug in everything and turn it on, my mouse and keyboard turn on fine, but my monitor wont, it says "Cable Not Connected" despite the fact i did connect the cable, then when i go to check the input options as i assume thats the problem, I dont see a USB option, much less a USB 3.0 option, despite it giving me a 3.0 cable, the only options it does give me are DP, HDMI1(2.0), and HDMI2(2.0). My tower doesnt have a port for an HDMI cable so i need to use the USB cable it gave me. Is there something im missing to getting this working? any and all help would be appreciated
