Buying advice

For competitive players who prefer a compact 24.5-inch Full HD IPS screen and a high refresh ceiling. In the Japanese configuration, DisplayPort supports 300 Hz, HDMI tops out at 240 Hz and G-SYNC Compatible uses DisplayPort. Height, swivel and pivot adjustments help position the screen; choose a higher resolution if fine detail matters more than the refresh ceiling.
