The Samsung Odyssey G7 S28AG70 is the first 4k monitor in Samsung's Odyssey gaming lineup. It has a 144Hz refresh rate with HDMI 2.1 inputs, meaning you can achieve its max refresh rate with a 4k resolution over both DisplayPort and HDMI connections. The two HDMI 2.1 inputs support 4k @ 120Hz gaming from the Xbox Series X, PS5, or PCs. There's native FreeSync variable refresh rate (VRR) support, and it's certified by NVIDIA to be G-SYNC compatible. It's different from the Samsung Odyssey G7 C32G75T because it has a flat screen, and it has an IPS panel with wide viewing angles, which also means it has a low contrast ratio that makes blacks look gray.
Our Verdict
The Samsung G70A is great for most uses. It's excellent for gaming because it has fantastic motion handling, low input lag, and a 144Hz refresh rate with HDMI 2.1 inputs. It's also great for content creators, office use, or consuming multimedia content because its 4k resolution produces sharp text, and the wide viewing angles result in an accurate image when viewing from the sides. It's decent for HDR gaming, but sadly it has a low contrast ratio and terrible local dimming that deliver a bad dark room experience.

The Samsung G70A is a great office monitor. It has a large 28 inch screen with a high 4k resolution for exceptional text clarity and sharp images. It has wide viewing angles, making it a good choice if you need to share the screen with a coworker, and the ergonomics are great, but the swivel range is narrow. Also, it gets bright enough to fight glare in most rooms, but its reflection handling is just decent.

The Samsung G70A is great for content creators. The 4k resolution and 28 inch screen help deliver clear images and sharp text. The wide viewing angles make it easy to share your screen with a client, but it has a narrow swivel range, so it's harder to turn the screen. It also has good out-of-the-box accuracy, exceptional gradient handling, and a fantastic SDR color volume, so colors appear as they should while editing.

Popular Monitor Comparisons
The Samsung G70A is an excellent gaming monitor. It has fantastic motion handling, low input lag, and VRR support, and the HDMI 2.1 inputs make it a worthwhile choice if you have an Xbox Series X. However, if you have a PS5, you need to make sure you can update the firmware to get 4k @ 120Hz gaming. It's a downgrade compared to the Samsung Odyssey G7 C32G75T in dark room performance, but it has wider viewing angles instead.

The Samsung Odyssey G7 S28AG70 is much better than the Samsung Odyssey G55T C27G55T because it's a higher-end monitor. The S28AG70 has a 4k resolution that delivers sharp text, while the C27G55T has a 1440p resolution. The S28AG70 has an IPS panel with wider viewing angles, and the C27G55T has a VA panel with better contrast. They each have a 144Hz refresh rate, but the S28AG70 has much better motion handling thanks to the quicker response time, especially at 60Hz, and it also gets brighter. The S28AG70 has a local dimming feature, which the C27G55T doesn't have, but it doesn't add much because it's terrible.
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 BG70 is available in 28- and 32-inch screen sizes, while the AG70 is available in just a 28-inch screen size. The BG70 improves in a few areas, like peak brightness, reflection handling, and motion handling. It also has a built-in Tizen OS smart platform, which the AG70 doesn't have, letting you stream content without a PC.
The LG 27GP950-B and the Samsung Odyssey G7 S28AG70 are both high-end 4k gaming monitors. They have many of the same features with HDMI 2.1 inputs, and even though their native refresh rates are both 144Hz, the LG is overclockable to 160Hz. The LG also has better motion handling at 60Hz, and it gets much brighter, especially in HDR. The HDMI 2.1 inputs on the LG support a higher 48 Gbps bandwidth compared to 40 Gbps from the Samsung, but it doesn't make a difference unless you need to achieve 4k @ 120Hz signals with 12-bit color depth. On the other hand, the Samsung has better ergonomics because you can swivel it.
The Samsung Odyssey Neo G7 S32BG75 and the Samsung Odyssey G7 S28AG70 are both 4k gaming monitors with a few differences. The S32BG75 is better for dark room gaming because it has a higher contrast and its Mini LED local dimming results in deeper blacks, while the S28AG70 is better for co-op gaming as it has wider viewing angles. The S32BG75 is also slightly better for gaming as it has a quicker response time, especially with lower frame rates.
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.
