The Samsung Odyssey G7/G70B S32BG70 is a 32-inch, 4k gaming monitor. It's a newer version of the Samsung Odyssey G7 S28AG70 with many of the same features, including HDMI 2.1 bandwidth for console gaming and VRR support. Unlike the higher-end Samsung Odyssey Neo G7 S32BG75, this one is limited to a 144Hz refresh rate and doesn't feature Mini LED backlighting. However, it features Samsung's proprietary Tizen OS smart platform built-in, letting you stream content without needing a PC, and it has extra connectivity options like built-in Wi-Fi and Bluetooth support. There's also a smaller S28BG70 model available, but it's considered a different monitor, and not a variant.
Our Verdict
The Samsung Odyssey G70B is decent for PC gaming. It supports any VRR format to reduce screen tearing, and it has a 144Hz refresh rate. It also has low input lag at high refresh rates and a quick response time, but there's still some motion blur, and the input lag increases at 60Hz. Its 4k resolution delivers detailed images, but it has limited picture quality as it has a low contrast ratio and terrible local dimming feature, so blacks look gray in dark rooms.
- 4k resolution for sharp details.
- Low input lag at high refresh rates.
- Consistently fast response time at any refresh rate.
- Supports any VRR format.
- Low contrast ratio.
- Highlights don't pop in HDR.
- Input lag increases at 60Hz.

The Samsung G70B is great for console gaming. With HDMI 2.1 bandwidth and a 4k resolution, it can take full advantage of the PS5 and Xbox Series X|S with any signal. It has a fast response time that makes motion look sharp, and it has a low input lag at 120Hz for a responsive feel, but its input lag increases at 60Hz. Unfortunately, it fails to make HDR games look life-like, as it has a low contrast ratio and terrible local dimming feature, and highlights don't pop in HDR.

The Samsung G70B is great for office use. The large 32-inch screen lets you open multiple windows at once, and the 4k resolution helps deliver sharp text. It also gets bright enough to fight glare if you want to use it in a well-lit office, and the reflection handling is very good. Lastly, it has wide viewing angles and excellent ergonomics, making it easy to adjust to an ideal position if you need to share your screen with someone else.

Popular Monitor Comparisons
The Samsung G70B is a 4k gaming monitor competing with other monitors that have similar specs, like the LG 32GQ950-B and the Sony INZONE M9. It provides good value against the competition, as it has a consistently fast response time, low input lag, and HDMI 2.1 bandwidth to take full advantage of the PS5 and Xbox Series X|S. That said, it has worse picture quality than the Samsung Odyssey Neo G7 S32BG75, and you can find other similar-performing 4k gaming monitors for less, like the LG 32GR93U-B, so only consider this monitor when you can find it at a lower price.

The Samsung Odyssey G7/G70B S32BG70 is the newer version of the Samsung Odyssey G7 S28AG70 with many of the same features and performance.

The Gigabyte M32UC and the Samsung Odyssey G7/G70B S32BG70 are both great 4k, 32-inch monitors with a few differences. They have different panel types, so while the Samsung has wider viewing angles, the Gigabyte has a better contrast for deeper blacks. The Gigabyte also gets brighter both in SDR and HDR. However, in terms of gaming, the Samsung monitor has better motion handling thanks to its quicker response time.
The Samsung Odyssey Neo G7 S32BG75 is a higher-end version of the Samsung Odyssey G7/G70B S32BG70, so it's better overall. The main difference is that the Neo G7 has a VA panel with Mini LED backlighting, resulting in a much better contrast and local dimming feature. It also gets brighter in HDR, particularly with smaller highlights. On the other hand, the G70B has better motion handling as there's less overshoot.
The Samsung Odyssey G7/G70B S32BG70 and the Gigabyte M28U are both great 4k, 144Hz monitors. They share many similarities, including a fast response time, and while the Samsung has a faster response time at 60Hz, the Gigabyte has lower input lag with 60Hz signals. The Samsung also gets brighter if you want to use it in a well-lit room, but the Gigabyte has more work-oriented features like a USB-C input.
We buy and test more than 30 monitors each year, all of which we purchase ourselves, without cherry-picked units or samples. We put a lot into each unbiased, straight-to-the-point review, and there's a whole process from purchasing to publishing, involving multiple teams and people. We do more than just use the monitor for a week; we use specialized, custom tools to measure various aspects and deliver objective, data-driven results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance compared to the competition, and whether it's easy to find.
