No-name 27-inch office monitors with 1080p panels and 60Hz refresh rates regularly sell for more than what the ASUS TUF Gaming VG27AQM5A costs right now. Prime Day just dropped a 1440P 300Hz gaming monitor to a price that makes the comparison difficult to explain: Amazon has it at $189, down from its $299 standard price and an all-time low for this 27-inch Fast IPS gaming monitor with 0.3ms response time, ELMB Sync, 95% DCI-P3 color coverage, Shadow Boost, and a 3-year manufacturer warranty. This deal requires Prime membership, and the 30-day trial needs no card.

300Hz and 0.3ms on a Fast IPS panel at this price

The three specs that define competitive gaming monitor performance are refresh rate, response time, and panel technology, and the ASUS TUF VG27AQM5A delivers at the top end of all three. The 300Hz refresh rate means the display can show 300 distinct frames per second, which at high frame rates produces genuinely smoother motion than 144Hz or 165Hz monitors, particularly in fast-paced shooters where the difference between seeing an enemy clearly and seeing motion blur is measured in frames. The 0.3ms GTG response time is among the fastest available on any current panel technology, eliminating the ghosting that slower IPS monitors produce on fast-moving objects.
