Buying advice

ROG Strix XG27ACNS suits competitive gaming when you can drive very high frame rates: its QHD mode reaches 475Hz with overclocking, while 620Hz and 920Hz modes trade resolution for refresh rate. Choose the mode around the games and graphics hardware you use. The adjustable stand and USB-C video input add desk flexibility, but 15W USB-C power is better suited to small devices than powering a work laptop.
