Cons

✗ 1920x1080 only, so no extra desktop space for multitasking

Manufacturer description

The Samsung Odyssey G4 LS25BG402EN packs a 25-inch FHD IPS panel with a 240Hz refresh rate and 1ms GtG response time, aimed squarely at competitive shooters where frame pacing decides the fight. The IPS panel holds color and contrast across a 178-degree viewing angle, so the image stays consistent whether you're centered or leaning. Adaptive sync runs both ways: NVIDIA G-SYNC Compatible certification and AMD FreeSync Premium keep the panel locked to your GPU's output, cutting tearing and stutter in fast pans. Ultrawide Game View switches the aspect ratio to 21:9 for titles that reward…

Frequently Asked Questions

Does the Odyssey G4 really hit 240Hz?

Yes. The LS25BG402EN runs a 240Hz refresh rate at 1920x1080 with a 1ms GtG response time. Use DisplayPort for the full 240Hz; HDMI bandwidth limits vary by cable and source device.

Will this monitor work with an NVIDIA or AMD graphics card?

Both. It is NVIDIA G-SYNC Compatible and supports AMD FreeSync Premium, so adaptive sync eliminates tearing and stutter regardless of which GPU you run.

What is Ultrawide Game View and when would I use it?

It switches the display to a 21:9 aspect ratio, widening your field of view in supported games. Samsung cites soccer titles showing more of the pitch and driving games showing more road ahead.

Can I adjust the height, or just the tilt?

The stand is fully adjustable with swivel, tilt, and height movement, so you can set the panel position for long sessions rather than propping it on books.
