Samsung Odyssey G4 (G40B)
A compact 25" competitive monitor built around a 240Hz IPS panel with a 1ms GtG response, dual G-Sync Compatible and FreeSync Premium support, and a fully adjustable stand that most sub-$250 gaming monitors leave out. The smaller 25" size keeps 1080p pixel density reasonable and puts the whole picture inside your field of view.

Our Verdict
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.

Alternatives to Consider
ASUS ROG Strix XG259QNS
ASUS
A purpose-built esports display. The XG259QNS pushes a Fast IPS panel to 380Hz (overclocked) with a rated 0.3ms minimum response and ELMB Sync, which lets ASUS run backlight strobing and variable refresh at the same time, the closest thing to CRT-like motion clarity you can buy under $300.
Acer Nitro XV272U W2bmiiprx
Acer
The value sweet spot for competitive play. Acer pairs a 27" 1440p IPS panel with a 240Hz refresh ceiling and a 0.5ms VRB motion mode, giving you the sharper QHD image most shooters benefit from without giving up the high frame rates competitive gaming lives on, and it routinely sells well under $200.
GIGABYTE M27Q X
GIGABYTE
A do-it-all 1440p 240Hz panel with a work-and-play twist. GIGABYTE's M27Q X runs a 27" Super-Speed IPS at 240Hz with a 1ms MPRT response and 92% DCI-P3 color, then adds a built-in KVM and USB-C so a gaming PC and a work laptop can share the same screen, keyboard, and mouse.
Dell 27 Gaming Monitor SE2726HG
Dell
The cheapest honest way onto a 240Hz IPS panel. Dell's SE2726HG delivers a 27" 1080p IPS display at 240Hz with FreeSync Premium and a 0.5ms Extreme response mode, backed by a 3-year warranty, the entry point for competitive frame rates when the budget is truly tight.
