LG 24BK400H-B 24" Black 2018

★★★★☆ 4.4 (591)

A 24-inch TN panel with 75 Hz refresh rate and AMD FreeSync reduces screen tearing during fast-paced gaming. Its On Screen Control software lets you adjust brightness and volume with a mouse, and the 4218g build is sturdy for a budget monitor. Best for casual gamers on a tight budget who want smoother motion without paying for an IPS panel.
