I've been running 1440p at 120Hz on my Series X for months. Just make sure to use a high-quality HDMI 2.1 cable and check your display's manual for supported resolutions and refresh rates!
Just use a monitor that supports it. Change display settings to 1440p and set refresh rate to 120Hz in the system settings. Done.
Remember to check if your monitor鈥檚 firmware needs an update! I had to do that to get mine to work perfectly.
