The Samsung CF791 is a decent ultrawide monitor. It has a VA panel that can produce deep dark scenes which is good for those in a dark room. It also has great gray uniformity, which is good for watching videos or browsing the web. Unfortunately, the image degrades when viewed at an angle, but the curvature of the display helps to mitigate this. The C34F791 also has great motion handling with a fast 100Hz refresh rate.
Our Verdict

- Can produce deep dark scenes.
- Colors appear uniform.

This is a decent monitor for office use. Its large screen and excellent resolution give you enough room and detail to work. Unfortunately, the image degrades at an angle and the poor ergonomics won't allow you to easily work side-by-side with a colleague.
The Samsung C34F791 is a good monitor for gaming. It has an ok input lag, fast response time for a smooth image, and the FreeSync implementation of the variable refresh rate technology to prevent tearing. The large size and the excellent resolution of the monitor, give you more screen area and more detail to immerse yourself in your favorite game.
This is an ordinary monitor for multimedia usage. Its large size and excellent resolution, along with its good reflection handling are its main advantages. On the other hand, the poor viewing angles and the bad ergonomics make it difficult to position it in a comfortable position to enjoy the best picture quality.
The Samsung C34F791 is a decent monitor for media creation. Due to its size and resolution professionals will find it very comfortable for working. However, the coverage of the Adobe RGB color space might not be enough for those who will be using it for publishing or printing applications.
Unfortunately, the Samsung CF791 doesn't support HDR like the Samsung CHG70.

Popular Monitor Comparisons
The Samsung CF791 is a decent, large screen ultrawide monitor. See our recommendations for the best curved gaming monitors, the best gaming monitors for Xbox One X, and the best ultrawide gaming monitors.
If you've got a large room with wide seating, then the Dell U3417W is a better choice, but if you're interested in gaming in a dark room while sitting directly in front, then the Samsung C34F791/CF791 is better. The Dell U3417W has an IPS panel, giving you better viewing angles, whereas the CF791 has a slightly better refresh rate and a slightly faster response time resulting in clearer motion.
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.
The Samsung CHG70 is much better than the Samsung C34F791/CF791. The CHG70 has much lower input lag, supports HDR, and is equipped with local dimming to make blacks even deeper. You can position it according to your liking and you'll enjoy it in every use. The CF791, on the other hand, is larger, giving you more screen area and more resolution to work with.
The LG 34UC79G-B is a better monitor than the Samsung C34F791/CF791 for almost every use, unless you'll be using it in a dark room. The Samsung CF791 has better resolution giving you more details on the screen, but the LG34UC79G has better viewing angles, and you'll enjoy gaming more as it has significantly better input lag and marginally better image flicker to clear blur.
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.
