Our Verdict

Gigabyte M27Q (rev. 1.0)

Samsung Odyssey G51C S27CG51

The Gigabyte M27Q (rev. 1.0) is a better budget-friendly gaming monitor than the Samsung Odyssey G5/G51C S27CG51. The Gigabyte has much better motion handling thanks to its faster response time, and it has a few extra features like a USB hub, including a USB-C port. The Gigabyte is also better for everyday use, like if you want to use it in a well-lit room, as it gets brighter and displays a wider range of more accurate colors. The Samsung has an advantage if you want to use it in a dark room because it has a better contrast ratio. The Samsung also has better ergonomics, making placing it in an ideal position easier.
