ASUS ROG Strix XG259QN380 Hz

Manufacturer specification · Manufacturer-listed maximum; input-specific signal-frequency restrictions, overclocking and source/cable requirements remain as shown in the specifications. Digital Signal Frequency : HDMI: 27~292 KHz (H) / 48~240 Hz (V) DP (OC): 470~470 KHz (H) / 60~380 Hz (V)

LG 27G550B-B300 Hz

Manufacturer specification · Manufacturer display-table maximum, not a motion index. Input-specific modes/overclocking remain in original source fields. Original: 300

Explore the full specifications

Match the monitor to the connection. Refresh limits depend on the input, cable and source device. Confirm the exact regional ports, stand adjustment and mount. Manufacturer response-time methods such as MPRT and GtG are different; neither the image nor these figures establish an independent motion or colour-quality test.
