Our Verdict
Gigabyte M28U
Samsung Odyssey G7/G70B S32BG70
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.
