ASUS Republic of Gamers announced the commercial rollout of its 720 Hz Swift OLED PG259QWS Ace on October 28, putting a $1,099 U.S. price on a 24.5-inch monitor built for competitive esports. A second model, the 540 Hz Strix OLED XG259QWPG Ace, carries a $699 suggested U.S. price.

Both monitors use 1920 × 1080 Tandem WOLED panels, prioritizing rapid image updates over the higher resolution favored by many general-purpose displays. The trade-off also figures in our LCD-versus-OLED comparison. ASUS lists 0.02-millisecond gray-to-gray response times, 99.5% DCI-P3 color coverage and up to 1,700 nits of peak HDR brightness. Those are manufacturer specifications, not independent laboratory measurements.

At 720 Hz, the flagship can begin a new refresh about every 1.39 milliseconds, compared with 1.85 milliseconds at 540 Hz. That 33% increase in refresh frequency does not automatically mean a player reacts 33% faster: game frame rates, system latency and human perception also matter.

Getting the full 720 Hz requires a sufficiently fast graphics system and compatible connections. The flagship includes DisplayPort 2.1 UHBR20 and two HDMI 2.1 inputs; its sibling uses DisplayPort 1.4 with compression support. Our HDMI versus DisplayPort guide explains why interface bandwidth matters.

The Cost of Higher Refresh Rates

ASUS also provides a Position Sensor to reproduce monitor height and angle, three esports color modes, and a proximity-based OLED protection feature. The company backs both panels with a three-year warranty covering burn-in. Those protections may reduce risk, but do not eliminate it.

The PG259QWS Ace is designated the official display for the 2026 PGL Counter-Strike 2 Major in Singapore. That tournament partnership was announced in August; the October development concerns commercial availability and pricing, not the monitor’s first public unveiling.

The difference in price is substantial: the 720 Hz model costs $400 more than the 540 Hz version. Buyers should weigh the benefit against hardware capable of producing very high frame rates. Our gaming graphics-card rankings and desktop CPU comparisons provide broader performance context.

Retail timing remains market-specific. Notebookcheck reports that British listings show later November delivery dates despite ASUS describing the monitors as available. Independent testing will determine how much their advertised motion clarity improves real matches and whether buyers accept the price premium.
