Samsung Odyssey G4 series, available as the S25BG40 and S27BG40 models. As their model names suggest, the S25BG40 and S27BG40 are 25-inch and 27-inch monitors, respectively. Samsung only distinguishes the two 240Hz gaming monitor models by their weight, dimensions, and panel size; all other characteristics are common.

Specifically, Samsung equips the Odyssey G4 series with IPS panels that display 1080p resolution in a 21:9 aspect ratio. According to Samsung, the pair offers 1ms GtG response times, 240Hz refresh rates, and up to 400 nits of peak brightness. Additionally, Samsung promises 99% sRGB color space coverage, a 1000:1 contrast ratio, and 178°(H)/178°(V) viewing angles. Unsurprisingly, Samsung has included AMD FreeSync Premium and NVIDIA G-SYNC support to reduce image tearing.

Additionally, the Odyssey G4 series features an Eco Light sensor, low input lag mode, and refresh rate optimizer. In addition, Samsung has equipped both monitors with two HDMI 2.0 ports, a DisplayPort 1.2 connection, and a 3.5mm headphone jack. Unlike other new Odyssey series Samsung gaming monitors, the Odyssey G4 lacks USB ports. Unfortunately, Samsung has yet to confirm pricing for the S25BG40 or S27BG40.
