Our Verdict
Samsung Odyssey Neo G8 S32BG85
Cooler Master Tempest GP27U
The Samsung Odyssey Neo G8 S32BG85 and the Cooler Master Tempest GP27U are both excellent 4k gaming monitors. The main difference is that the Samsung monitor has a much higher 240Hz refresh rate, making it future-proof for 4k gaming at a high frame rate. They each have Mini LED local dimming that performs decently, and while the Cooler Master has lower native contrast, it still displays deep blacks like on the Samsung. The Cooler Master also has better motion handling and doesn't have the same bugs the Samsung has, like flicker with low frame rates, and it has a few extra features like a USB-C port and a KVM switch.
