Sorry, the question was difficult to word. Basically I recently bought a controller board for a monitor and the DC cable I got wasn't correct. So until I get the right part, I just want to test the board and the monitor to see if they work.
When I turn it over, where the DC 12V jack is, there are 4 pads: 2x 12V and 2x Ground. Is there a way I can simply connect a red and black wire just to test?
[Here is an image to explain it further.]
All I want to do is connect a red and black wire, which I will connect to step up board, as this will be powered by USB, and supply 12V. (Don't worry, I checked all the amps, and voltages first, and please don't give any alternative ways of doing this.) I just don't want to go ahead and connect two wires and cause something to break.
EDIT: Which ones do I connect to? Both of the 12v and gnd? Or a specific one?
Many thanks.

Just connect one wire to one of the 12V pad and the other wire to one of the GND pad.
Although there are 2 pads for 12V, the pads are interconnected so it doesn't matter which pad you connect to. Same applies for GND.
