Our Verdict
Acer Nitro XV272U KVbmiiprzx
Samsung Odyssey G51C S27CG51
The Acer Nitro XV272U KVbmiiprzx is a better 1440p gaming monitor than the Samsung Odyssey G51C S27CG51. The Acer uses a different panel type with better motion handling, and it has a few extra features like a USB hub. The Acer also gets brighter, making it a better choice to use in a well-lit room, and it has wider viewing angles that are ideal if you need to share the screen with someone else. On the other hand, the Samsung is better for use in dark rooms thanks to its superior contrast ratio for deeper blacks.
