Our Verdict
Acer Predator XB271HU Bmiprz
Samsung C34F791/CF791
If you want to work on the same monitor side-by-side with your colleagues at the office, then the Acer Predator XB271HU Bmiprz is a better choice than the Samsung C34F791/CF791 as it has better viewing angles. The Acer is also better for gaming as it has better input lag, better image flicker to clear blur, and you can easily position it to match your liking. On the other hand, the Samsung CF791 is a larger monitor with higher resolution, giving you more area and more detail to work with.
