Pros & Cons Side by Side

ASUS ROG Swift PG259QN 360Hz Esports Monitor

360Hz refresh rate at 1080p FHD — maximum frames per second for competitive play

1080p in 2026 — 1440p is more future-proof for non-competitive use
24.5-inch limits immersion for single-player games versus 27-inch alternatives
Premium pricing for an FHD monitor when QD-OLED alternatives approach at similar cost

Both G-Sync Compatible and FreeSync Premium for any GPU brand
1ms GtG response with no significant ghosting
8,400 reviews at 4.7★ — the community's favourite 1440p gaming monitor

IPS contrast lower than VA or OLED for dark-scene atmosphere
HDR is HDR400 tier — not genuine HDR brightness
27-inch 1440p is the sweet spot but not the largest or sharpest option
