I could not get your screenshot to load. Anyway, note where the connector from your monitor fits on to the display output port at the back of your CPU.
If you have onboard graphics, the port will be in the upper half of the CPU, near the other ports like mouse, keyboard, USB, etc. The long side of the connector will be vertical.
If you have a separate graphics card, the port will be in the lower half of the CPU. And the long side of the connector will be horizontal.
There may be a few exceptions to these rules, but they will look like that in the vast majority of computers.
