Samsung has lifted the lid on the Odyssey G4 series, to be available in 25-inch and 27-inch display sizes. The Odyssey G4 series offers flat-panel gaming at up to 240 Hz with HDMI 2.0 and DisplayPort 1.2 connections. Samsung promises 1 ms GtG response times and 1080p native resolutions too, among other features.

Samsung has introduced the Odyssey G4 series, available as the S25BG40 and S27BG40. As their model names suggest, the S25BG40 and S27BG40 are 25-inch and 27-inch monitors, respectively. Seemingly, Samsung only distinguishes the pair from each other with their weight, dimensions and panel size; all other features are shared.

Specifically, Samsung equips the Odyssey G4 series with IPS panels that output at 1080p in 21:9 aspect ratios. According to Samsung, the pair offer 1 ms GtG response times, 240 Hz refresh rates and up to 400 nits of peak brightness. Additionally, Samsung promises 99% sRGB colour space coverage, a 1,000:1 contrast ratio and 178°(H)/178°(V) viewing angles. Unsurprisingly, Samsung has included AMD FreeSync Premium and NVIDIA G-SYNC support for reduced image tearing.

Moreover, the Odyssey G4 series has an Eco Light sensor, a low input lag mode and a refresh rate optimiser. Incidentally, Samsung has equipped both monitors with dual HDMI 2.0 ports, a DisplayPort 1.2 connection and a 3.5 mm headphone jack. Unlike Samsung's other new Odyssey gaming monitors, the Odyssey G4 lacks any USB ports. Unfortunately, Samsung has not confirmed S25BG40 or S27BG40 pricing yet.
