@chW33Nie Yes, you can plug a monitor into a laptop as long as you have the correct type of cable. It looks like the Victus has a full-size HDMI port, meaning you could use a standard HDMI cable to connect it to a monitor, but see for yourself (and read the manual) before spending any money on a cable. The laptop will definitely have something though, if not a full-size HDMI port then perhaps mini HDMI or mini DP. Suitable cables should be cheap if the monitor in question supports HDMI or DisplayPort; otherwise, you might need an adapter.
I'd still try playing on the Victus's screen before spending any money at all. Laptop screens are small, sure, but you can also get really close, and 1920x1080 looks much more crisp and clear on a 16" screen than a 24" monitor.
