To use my laptop as a second monitor for my pc?

Depends on the laptop and the graphics card inside it. Macs have an option called Target Display Mode that can do this.

Nope, the ports on your laptop work only one way. Macs were designed to have this work from the getgo with thunderbolt ports.

There are a select few Windows systems that have an actual input for HDMI/etc, but that depends on the model of the system. Basically, if the computer doesn't have an HDMI/DVI/VGA input (note: This is different than an output, which virtually all systems have these days), it won't support this.

i have a better idea

setup your laptop near your desktop monitor as if you were going to use it as a second monitor, then set up a remote on it and control it with your desktop

this way you can use the cpu and gpus of both independently

I said screw it and bought a benq monitor on Kijiji for 30$

Next question is...
Am i able to use 2 mouse cursors? 1 mouse per monitor? so i can play 1 game that isnt in windows and other running on the side so i dont have to Alt + Tab to use next game

wtf?

what is so wtf about my question?
