How they differ in real use
Built from our competitive fps monitors under 300 scoring, each product's published specifications, and verified owner feedback — not hands-on testing.
Both the ASUS ROG Strix XG259QNS and the Dell 27 Gaming Monitor SE2726HG made our Top 5 Gaming Monitors for Competitive FPS Under $300, at #1 (best overall) and #5 (best budget). For pure competitive FPS this is the one to beat: a Fast IPS panel overclocked to 380Hz with a rated 0.3ms minimum response, and ELMB Sync that runs backlight strobing and variable refresh together. Nothing else under $300 combines this much refresh headroom, this little motion blur, and this low latency in one esports-tuned package. The cheapest credible way onto a 240Hz IPS panel. Dell puts a 27" 1080p IPS at 240Hz with FreeSync Premium and a 0.5ms Extreme mode behind a 3-year warranty, often for around $150. The tilt-only stand, low 1080p pixel density on a 27" screen, and entry-level overdrive are the compromises that keep the price down.
