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 GIGABYTE M27Q X and the Samsung Odyssey G4 (G40B) made our Top 5 Gaming Monitors for Competitive FPS Under $300, at #3 and #4. 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. A focused 25" 1080p 240Hz IPS competitive monitor with a 1ms GtG response, dual G-Sync Compatible and FreeSync Premium support, and a fully adjustable stand that rivals at this price usually skip. The smaller screen suits players who want the whole picture in their field of view, but 1080p and no 1440p option hold it below the QHD picks.
