How to Choose the High Performance Monitor
Resolution and size
Resolution decides how sharp text and games look at a given size. 1440p is a strong balance for most desks, 4K is sharper but needs a stronger graphics card, and 1080p is the cheapest option.
Refresh rate
A higher refresh rate makes motion and scrolling smoother. 144Hz is a good starting point for gaming, and 240Hz or more helps in fast shooters if your graphics card can keep up.
Panel type
IPS gives accurate colour and wide viewing angles, VA gives deeper contrast, and OLED gives near-instant response and perfect blacks. Choose by what you do most.
Ports and connectivity
Check for DisplayPort and HDMI, and for USB-C if you want a single-cable laptop setup. Look at the listing for HDMI 2.1 if you use a console.
Adaptive sync
FreeSync or G-Sync compatible support removes tearing when your frame rate changes. Most modern gaming monitors include one of them.
