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 GIGABYTE M27Q X made our Top 5 Gaming Monitors for Competitive FPS Under $300, at #1 (best overall) and #3. 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. A near-twin to the Acer on gaming specs — 27" 1440p Super-Speed IPS at 240Hz with a 1ms MPRT response — that pulls ahead for anyone sharing the screen between a gaming PC and a work laptop, thanks to its built-in KVM and USB-C. It costs a little more than the Acer and has no strobing mode, which is why it lands just behind.
We score gaming monitors for competitive fps under $300 on Motion Clarity (30%), Refresh Rate (25%), Input Lag (15%), Panel & Resolution (15%) and Value (15%).

The widest gap is Motion Clarity, where the ASUS ROG Strix XG259QNS scores 9.6 against 8.4 for the GIGABYTE M27Q X — pixel response and motion blur reduction. Refresh Rate also separates them: 10 for the ASUS ROG Strix XG259QNS versus 8.6 for the GIGABYTE M27Q X. The GIGABYTE M27Q X claws back ground on Panel & Resolution and Value.
