HDR Gaming

The Samsung C27HG70 is a good monitor for most uses. The VA panel delivers deep blacks, and it can display a wide color gamut, great for watching HDR content. It's a great gaming monitor thanks to its low input lag and excellent response time at 144Hz, but unfortunately, it has a bad response time at 60Hz, so it's not a good choice for console gamers. Like most VA panels, the image degrades when viewed at an angle, which might be an issue for some people.

Our Verdict

7.7 Mixed Usage

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.

Pros
  • High contrast gives good picture quality.
  • High refresh rate for gaming.
  • Wide color gamut and HDR support.
Cons
  • Cloudy blacks lack uniformity.
  • Narrow viewing angles.
  • Bad 60Hz response time.
7.5 Office

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.

8.2 Gaming

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.

7.6 Multimedia

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.

7.8 Media Creation

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.

7.3 HDR Gaming

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.

Compared To Other Monitors

Comparison picture

Far Left: LG 27UD68-P. Left: Samsung CHG70. Right: Dell S2716DG. Far Right: Acer Predator XB271HU.

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.

Samsung Odyssey G7 C32G75T

The Samsung Odyssey G7 C32G75T is a much better gaming monitor than its predecessor, the Samsung CHG70. The Odyssey G7 has an upgraded 240Hz refresh rate, the response time is much quicker, it has a wider color gamut, and it has RGB illumination. However, the CHG70 has better out-of-the-box color accuracy, and its ergonomics are better.

HP OMEN 27

The Samsung CHG70 is a much better monitor than the HP OMEN 27 in almost every use. The Samsung has better contrast and overall better dark room performance. It also supports HDR and delivers better picture quality than the HP. The HP, on the other hand, has a TN panel and a very fast pixel response time that leaves a very small blur trail. Both monitors support variable refresh rate but through different implementations. The HP supports G-SYNC whereas the Samsung supports FreeSync. So be careful to have a matching graphics card or gaming console.

AOC CQ27G2

The Samsung CHG70 is much better than the AOC CQ27G2 for most users. The CHG70 has better ergonomics, higher peak brighteness, and it supports HDR. On the other hand, the AOC has a much better response time at 60Hz, making it a better choice if you're planning on gaming on a console.

AOC CQ32G1

The Samsung CHG70 is better overall than the AOC CQ32G1. Both are available in a 27 and 32 inch size, but the Samsung has a different stand than the AOC. The Samsung has a much faster response time at its max refresh rate, it has a local dimming feature, it supports HDR, and its ergonomics are better. However, the AOC has wider viewing angles and better out-of-the-box color accuracy.

Update 08/09/2019: There was a mistake in our swivel range scoring. The ergonomics score has increased slightly.

The ergonomic adjustments of this monitor are very different from other monitors. When moved up and down, the screen stays in the same orientation but the two pieces that make up the arm of the stand move relative to the base. It can take some time to get used to, but this offers a greater degree of flexibility than most monitors.

The Samsung CHG70 has a very good native contrast ratio. VA panels like this one generally have a better contrast ratio than IPS panels, especially when it's used in a dark environment.

The contrast ratio with local dimming set to 'On' is essentially the same as the native one. When displaying our checkerboard test pattern, the local dimming feature is ineffective at dimming the dark squares, as the dimming zones are quite large.

Like most monitors we've tested so far, including the Samsung CHG90, the local dimming feature is bad. There aren't many dimming zones, so the screen has to light up large areas at a time, which can be distracting in dark scenes.

Note that when the local dimming feature is set to 'Auto', the local dimming will only be turned on when HDR is detected.

Sub-par horizontal viewing angle, which is typical for VA monitors. The Samsung C27HG70 maintains its colors and brightness decently when viewed from the side, but its black level raises significantly even when only slightly off-axis. This causes the picture to look quite flat and dull and makes text difficult to read. Fortunately, its curve helps avoid the darkening of the sides from a normal viewing position.

The overall black uniformity of this monitor is poor. When local dimming is turned off, some backlight bleed is visible in much of the top and bottom part of the screen, leaving only some little portion of the screen free of it.

With local dimming enabled, the overall uniformity is worse, as the large dimming zones result in a large bar across the center of the screen.

After calibration, the CHG70's accuracy is excellent. Any remaining inaccuracies aren't noticeable, and gamma is much closer to the sRGB target, so scenes are displayed at the correct brightness.

You can download our ICC profile calibration here. This is provided for reference only and shouldn't be used, as the calibration values vary per individual unit even for the same model due to manufacturing tolerances.

The Samsung CHG70 has an excellent SDR color volume. A combination of good contrast and larger than average color gamut helps it cover the sRGB volume almost entirely. Even if it doesn't come packaged with native Adobe RGB calibration, it can still reproduce that color volume better than average.

Good color volume. The monitor's high contrast ratio and local dimming help it show its wide color gamut at a large range of brightness levels.

The Samsung CHG70 does an amazing job of displaying our gradient test image. Only some minimal color banding was noted in the darker shades of color. Besides that, not many other issues could be noted, and no 8-bit banding was visible, as this monitor has a 10-bit color depth.

The monitor is thankfully completely free of color bleed. While some very faint bleeding is visible in our vertical picture, its appearance is exacerbated by the long exposure used by the camera and isn't perceivable with normal use.

The reflection handling of this Samsung monitor is very good. The curve is advantageous in most situations, smearing reflections across the screen and reducing their intensity. The semi-matte finish also helps to diffuse reflections on the screen. Overall, it's a great result for most rooms.

Unfortunately, text clarity on the CHG70 is only decent. Even after calibrating the display with Windows' ClearType, some issues are still noticeable in text. This shouldn't cause any issues for most people, but if you require pixel-perfect text, this might be a problem.

Excellent motion blur, which is good for watching fast-moving content as only a very short trail will be seen behind objects. The monitor's 0-20% transition takes far longer than all the others, so some ghosting is visible in very dark parts of images.

Surprisingly, the monitor's overdrive can't be adjusted; the other 'Response Time' setting modes only activate BFI, as explained in the Image Flicker section. Fortunately, the monitor's default overdrive is very good, producing fast transitions without adding much overshoot.

Unfortunately, the Samsung CHG70 has a bad response time when gaming at 60Hz. There's significant overshoot, especially behind dark objects, causing a long ghost trail. The response time can't be adjusted, either, unlike most monitors on the market. This isn't a good choice for console gamers.

The C27HG70's backlight has a strange high-frequency wobble, but can be considered flicker-free as far as the human eye is concerned, so images appear smooth. The 32" model (Samsung C32HG70) has flicker in its backlight according to TFT Central's measurements, which isn't good and will produce multiple trailing images.

The monitor has two BFI modes in its 'Response Time' setting: 'Faster' and 'Fastest'; which intentionally add flicker to clear up motion when the framerate matches the flicker rate exactly. This produces very clear images when playing fast-paced games. We recommend the 'Fastest' setting if you want BFI, as 'Fastest' has a narrower pulse spread than 'Faster'. This monitor's BFI has a few limitations, however: when it's active, the brightness can't be changed; BFI can't be activated when the monitor is in HDR mode; and the BFI frequency must be manually changed in the monitor's OSD by changing the 'Game -> Refresh Rate' setting.

This monitor has an excellent native refresh rate. It also supports AMD's FreeSync variable refresh rate technology, and although it isn't officially supported, it also worked with NVIDIA's G-SYNC Compatible feature, but only when connected over DisplayPort. If you want a monitor with a higher refresh rate, check out its successor, the Samsung Odyssey G7 C32G75T.

The monitor has a 'USB Super Charging' mode that increases the voltage supplied to USB port 2 for devices that support quick charging. The monitor also has an 'Eye Saver Mode' for night time viewing, which adds an orange filter over the screen to reduce blue light. This mode does severely hurt the contrast ratio, however, so we don't recommend it unless the screen is causing discomfort at night.

Controls

The monitor's OSD is controlled by a joystick on the back of the monitor, which doubles as the power button. The joystick is a very intuitive way to navigate the OSD, better than the (up/down/back/select) button scheme used by most monitors.

There are also three buttons on the underside of the bottom right corner (faintly visible in the photo) which can switch between saved settings modes called 'Game Setting 1/2/3'. Users can save different settings configurations to these modes, and switch between them on the fly.
