How to read this comparison
Manufacturer facts for the exact models shown. Not a quality rating or a test result.
“Different” means the known values differ, not that one is better.
Missing or conflicting evidence is marked and never counts as a difference. Source chips hold each fact’s sources and conditions.

Max refresh
Maximum manufacturer-listed refresh rate, not measured motion clarity. The port-specific limits below matter; HDMI and DisplayPort can support different modes.
ASUS VG248QEZ144 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: 30~83 KHz (H) / 50~76 Hz (V) DisplayPort/DVI: 30~140 KHz(H) / 50~144 Hz (V)
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.
Compare the supplied stand and mounting requirements. These affect positioning and desk fit; they do not establish panel quality. Check any separately stated limits or conflicting dimensions.
