Our Verdict
The CHG70 is a good monitor for mixed usage. Its better than average picture quality and great gaming performance make it a great choice for users looking to get a high performing monitor for home use. The good contrast ratio and native HDR support make it a good choice for watching movies, but it has poor black uniformity, which might be distracting in a dark room.
- High contrast gives good picture quality.
- High refresh rate for gaming.
- Wide color gamut and HDR support.
- Cloudy blacks lack uniformity.
- Narrow viewing angles.
- Bad 60Hz response time.
The C27HG70 is a good office monitor. The 27", 1440p resolution screen is great for multitasking, and the adjustable stand makes it easy to place it in an ideal viewing position. It has great peak brightness and good reflection handling, so glare shouldn't be an issue in a bright room. The image degrades when viewed at an angle, though, so it isn't ideal if you often share your screen.
This is a great gaming monitor overall. It has outstanding low input lag for a responsive gaming experience, and the high native refresh rate results in clear motion when gaming at 144Hz. Unfortunately, the 60Hz response time is bad, so it's not a good choice for console gamers.
The C27HG70 is a good monitor for enjoying a variety of media. The VA-type LCD TV gives it a higher than average contrast ratio which is the most important aspect of picture quality. It also covers the larger DCI-P3 color gamut well, which when combined with its HDR support gives it a very vibrant picture. It isn't perfect, however. It's not very uniform with some visible clouding, and its local dimming feature is quite rudimentary.
The Samsung C27HG70 is a good monitor for media creation tasks. The monitor supports the DCI-P3 color gamut, which means it's quite up to date with currently used colorspaces and allows for the production of HDR content. Its relatively high resolution is also quite useful for efficient virtual workspaces. Unfortunately, though, its uneven blacks might bother some, and its lack of support for the Adobe RGB color space means it is more oriented towards video content.
Decent HDR Gaming monitor. While the Samsung CHG70's wide color gamut helps make HDR games look very vibrant and saturated, its average brightness for HDR and basic local dimming feature limit the impact of displaying HDR content. It does, however, keep a very low input lag when connected to an HDR source, which is important for gaming.

Differences Between Sizes And Variants
The CHG70 we bought is the 27" model (Samsung C27HG70). It's also available in a 32" size (Samsung C32HG70). We expect this 32" model to have almost the same performance, but with a flickering backlight instead of the effectively flicker-free performance of the 27" model.
If someone's CHG70 doesn't correspond to our review, let us know and we'll update the review. Note that some tests such as the gray uniformity may vary between individual units.
| Model | Size | Refresh rate |
|---|---|---|
| C27HG70 | 27" | 144Hz |
| C32HG70 | 32" | 144Hz |
The CHG70 we tested was manufactured in August 2017.
Popular Monitor Comparisons
The CHG70 is a very good monitor, one of the best monitors for gaming and best curved gaming monitors we've tested, with a high refresh rate and better than average picture quality. See our recommendations for the best 1440p 144Hz monitors, the best mice, and the best keyboards.
The Samsung CHG70 is much better than the LG 32GK650F-B for most uses and is a bit better for gaming. The CHG70 supports HDR, has much better gradient handling, and has better reflection handling. The CHG70 also has a faster response time, with less noticeable blur behind fast-moving objects.
The Samsung CHG70 is better than the BenQ EW3270U. The Samsung CHG70 has much better ergonomics and local dimming support to enhance picture quality and can get brighter in HDR. The CHG70 also has a faster pixel response time, lower input lag, and faster refresh rate, all of which are great news for gamers. The BenQ EW3270U is larger with better resolution and marginally better black uniformity.
The two monitors are of a different type, each with its advantages and disadvantages. The ASUS ROG Swift PG279QZ has an IPS and the image remains accurate when viewed from the side so it's more suitable if you often work with a colleague on the same monitor. The ASUS also has a faster response time and fast-moving content is crisper. The Samsung CHG70, on the other hand, has a higher contrast ratio, supports HDR, and has a local dimming feature to enhance dark room performance, so it's more suitable for dark room viewing.
For most people, the VA panel Samsung CHG70 is significantly better than the TN panel Dell S2719DGF. The Samsung CHG70 has better dark room performance with more uniform blacks and local dimming support. The Samsung CHG70 supports HDR content and has a slight curve to immerse you into your work. The Dell S2719DGF, on the other hand, has a more versatile stand that allows you to place it in a comfortable position with ease, and a slightly faster pixel response time that leaves virtually no blur behind fast-moving objects.
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.
