Make sure your gaming laptop has a HDMI port, USB Type-A and Type-C ports for compatibility with both newer and older peripherals. An ethernet port is also great if you plan on using your laptop mostly as a desktop replacement, but latest 5GHz WiFi comes built into most all gaming laptops and is great for on-the-go or cable-free, wireless gaming setups. External accessories such as Thunderbolt 4 Dock can also be used for expanded port capabilities if needed.
