The Samsung CHG70 is a very good VA-type LCD monitor with better picture quality than average. It has a high contrast ratio as well as support for both HDR and wider color gamuts. It's especially great for gaming thanks to its high refresh rate of 144 Hz, low input lag, and FreeSync support. While it is quite versatile and sports a decently flexible stand, its narrow viewing angle makes it less suitable for environments where sharing with neighbors is commonplace. The CHG70 is available in two sizes: the 27" size (Samsung C27HG70) and the 32" size (Samsung C32HG70); we've reviewed the 27" model.

Although the styling is similar to the CHG90, the design of the Samsung CHG70 is a bit different to most other monitors. Although it looks great and is quite practical, there are a couple of tradeoffs with the unique design. For example, the arm of the stand means that it can't be placed close to a wall - especially if the monitor is in a low position. Ergonomic adjustments also aren't as good as some other monitors, so it may be slightly more difficult to find a comfortable setup. Both the Samsung C32HG70 and C27HG70 have the same unique design. The rear of the monitor can also light up with blue LEDs as seen here, which looks good.

The Samsung CHG70 has a similar stand base to their TVs such as the MU8000, and for a monitor, it is a relatively large footprint. It does feel stable though and provides good support.

Update 12/03/2018: Fixed a minor error with the height adjustment scoring; the ergonomics score has increased from 7.1 to 7.2 .

The ergonomic adjustments of this monitor are very different to 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.

Wall Mount : VESA 100x100

The rear of the monitor looks stylish. It is made of plastic but has a matte finish. Where the stand arm joins the monitor, there is a ring of LEDs which can pulse during use (see here). It is possible to mount the monitor using the included adapter.

Borders

The monitor itself is quite thin when viewed from the side, however, the stand takes up a lot of desk space. Depending on the height that it is set at, the stand protrudes out the back by a different amount. When at the lowest position, the monitor can sit 13.39" (34.0 cm) from a wall (shown here). The thickness measurement above is when the monitor is set to the maximum height, visible (here).

8.0 Build Quality

The build quality of the Samsung C27HG70 is great. The unique design feels well constructed, despite the plastic parts.

7.1

Picture Quality

The Samsung CHG70 monitors have a better than average picture quality. When used in a dark room or dim environment, the VA panel used in its construction really make it an excellent choice for those conditions. The very good contrast ratio means that the monitor can display deep blacks, which is particularly important for dark multimedia content or dark video games.

The black uniformity is poor though and the local dimming can really help that much at obtaining deeper black. If used in a bright room, the Samsung C27HG70 still fair pretty good, as it can get bright enough to fight glare and the screen finish does a very good job at dealing with reflections. The viewing angle is disappointing though, but this is the downside of using a VA panel in a monitor. The gray uniformity is excellent and dirty screen effect is really not a problem here.

Finally, HDR is better than average, as it got a decent HDR peak brightness and a very good coverage of the HDR color gamut. The only thing lacking that would really make HDR even better here would be a better local dimming, as the implementation is very bad and can't really help that much at making small highlight brighter or raising the contrast ratio more than what it already is.

7.8 Contrast
Native Contrast
:
2925 : 1
Contrast with local dimming
:
2922 : 1

The Samsung CHG70 has a very good native contrast ratio. With this high native contrast ratio, the monitor can display deeper blacks than what other IPS monitors can do, especially when it is used in a dark environment.

The contrast ratio with local dimming set to 'On' is almost the same as the native one since the zones are quite big and when displaying our checkerboard test pattern, the local dimming is not really effective at lowering the black level of the black square.

The C32HG70 (32" model) also has a VA panel, so we expect it to offer the same contrast ratio.

2.0 Local Dimming
Local Dimming
:
Yes
Backlight
:
Edge

Like on the CHG90, the local dimming on this Samsung monitor is bad. The number of zones is very limited, and they are implemented horizontally, which is especially visible when looking at the smaller highlight in our local dimming video. When the small highlight moves vertically, you can see the large horizontal local dimming zones turning on and off.

Another bad aspect of the local dimming is that it makes everything on screen much darker. When measuring the contrast ratio with local dimming, we had to raise the luminance of the monitor considerable to reach the same 100 cd/m². Since the zones are really large, it did not really change for the better the contrast ratio.

The one positive aspect of this type of implementation of local dimming, is that when watching movie with black letterbox, the top, and black bottom bars should remain much darker and free of blooming.

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

Average HDR peak brightness. Unlike most monitors, it does support the feature, however, it doesn't get any brighter than when an SDR signal is input. It isn't bad, but it doesn't get bright enough to define specular highlights properly and give a very significant HDR effect.

We have received reports that the 32" model (Samsung C32HG70) has a similar HDR peak brightness, with a maximum of around 600 nits.

Poor horizontal viewing angle. 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 darkening of the sides from a normal viewing position.

Poor vertical viewing angle. Much like on a horizontal axis, the colors and brightness fair decently when viewed at an angle. Unfortunately, its blacks shift even more rapidly to higher luminance levels. This can cause visible black clouding in corners of the screen even with slight head movements. This is most distracting when viewing letterboxed content.

The Samsung CHG70 has a great overall gray uniformity. Looking at the 50% gray uniformity test picture, the screen looks very uniform with only the top and bottom edges being a bit brighter at some points. Dirty screen effect is not problematic on this monitor.

Looking at the 5% gray test picture, some faint horizontal brighter bands are visible, the one near the top and bottom edge matching the brighter edge of the 50% gray picture. Besides this, not much more is really visible.

4.6 Black Uniformity
Native Std. Dev.
:
2.800 %
Std. Dev. w/ L.D.
:
3.443 %

The overall black uniformity of this monitor is poor. When the 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.

When the local dimming is turned on, it will turn off the backlight where nothing is displayed, and in the case of our test image, it turns off the backlight at the bottom and the top part. From our test point of view, this affect the uniformity of the screen though, as the middle part of the screen still have some clouding, versus the top and bottom which is now almost black, making the uniformity value much worse than before.

Note that here, we test the overall uniformity of the black, and not the black level.

The Samsung CHG70 has a very good 'Out of the box' accuracy. The most accurate measurements were done on the 'High-Brightness' 'Picture mode', with the 'Normal' 'Color tone'. Both the color dE and the white balance dE were under 3.0, which is very good for most people, except professional who might notice some inaccuracies. The color temperature was almost right on the 6500k target and looking at the CIE diagram, we see that the greens and reds are oversaturated a bit in the sRGB standard, but almost spot on when set to P3.

The gamma was a bit higher than our 2.2 target and looking at the gamma curve, we see that a peak in the lower and higher IRE value. The peak in the lower IRE values (dark) could cause some black crush in some multimedia content.

Most of the other pictures modes did offer similar accuracy to the 'High-Brightness when set on the normal color tone, only the 'Cinema' 'Picture Mode' had a worse accuracy out of the lot (white balance dE of 8.06 and color de of 6.96)

After calibration, the accuracy is excellent. The calibration was done with the 'Custom' 'Picture Mode' and with the 'Custom' 'Color Tone, as we needed to change the RGB values. The gamma issues were corrected and if you look at both dE, both the white balance dE and color dE were brought down by almost half, which is great result.

Good SDR color gamut, the Samsung CHG70 has no issue covering most of the essential s.RGB color gamut. While it is a wide gamut monitor, it does not feature an Adobe RGB setting, so those looking for support the more professionally oriented color space might be disappointed.

9.1 SDR Color Volume
sRGB in ICtCp

96.6 %
Adobe RGB in ICtCp

The Samsung CHG70 has an excellent SDR color volume. A combination of good contrast and larger than average color gamut helps it cover the s.RGB 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.

7.9 HDR Color Gamut

Very good wide color gamut, better than most HDR TVs. Saturated colors in HDR content will be well represented. The monitor's color accuracy is decent but could be improved.

7.2 HDR Color Volume
DCI-P3 in ICtCp
:
79.8 %
Rec. 2020 in ICtCp

Decent 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. Unfortunately, the monitor's tone mapping makes it narrow its DCI P3 color gamut at high brightness levels, which is odd because it should be able to show those saturated colors at high brightness.

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 as a 10-bit color depth.

10 Color Bleed
Pixel row error

0.000 %
Pixel column error

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.

8.0 Reflections

The reflection handling of this Samsung monitor is great. 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 is a great result for most rooms.

9.1

Motion

Motion looks excellent on the Samsung CHG70. This monitor's got it all: a flicker-free backlight, fast response time, high native refresh rate, AMD FreeSync 2 variable refresh rate technology, and optional Black Frame Insertion modes. While many monitors have a faster response time, very few can beat the CHG70's complete package.

9.0 Motion Blur

100% Response Time

Best Overdrive Setting
:
Standard

Excellent motion blur, which is good for watching fast moving content as only a very short trail will be seen behind objects. Most of the blur in the photo is due to persistence which is visible when your eyes move over the static image between frames. The monitor's 0-20% transition takes far longer than all the others, so some ghosting may be 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.

BFI Maximum Frequency

100 Hz

Update 05/16/2019: The PWM dimming frequency field was set incorrectly, and has been fixed.

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) on the other hand has flicker in its backlight according to TFT Central's measurements, which is not 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.

Update 06/17/2019: We incorrectly stated that the CHG70 does not support 1440p @ 120Hz when connected to an Xbox One. It does, but FreeSync must be fully disabled from the monitor's OSD for it to work.

High native refresh rate, with a great FreeSync range. The CHG70 is AMD FreeSync 2 certified, and as such has a wide enough FreeSync range to support Low Framerate Compensation (LFC), which effectively allows its range to extend below 20 Hz by sending double or triple frames when the framerate drops below the monitor's 48 Hz lowest native refresh rate.

Over HDMI the maximum refresh rate without FreeSync is 144 Hz, but with FreeSync it unfortunately drops to 100 Hz. Luckily FreeSync over HDMI on this monitor also supports LFC, extending its range below 20 Hz.

The monitor's OSD lists two FreeSync modes: 'Standard Engine' and 'Ultimate Engine'. The 'Ultimate Engine' had the widest FreeSync range and no adverse effects, so we only recommend the 'Standard Engine' if your game has problems with the 'Ultimate Engine'.

Update 01/15/2019: We have tested the CHG70 with NVIDIA's new FreeSync drivers, and there were no issues. Our tests were tear-free for the full FreeSync range, under both the 'Standard', and 'Ultimate' modes.

Inputs

The C27HG70 has large 27" size and a sharp 1440p resolution, which will please most anyone. It also has excellent low input lag in most cases, although its 60 Hz input lag is quite high.

Excellent low input lag. The input lag remains low when the monitor is in FreeSync or HDR mode, which is good. Unfortunately, the 60 Hz input lag is oddly high and strangely inconsistent, varying from ~44 to ~40 on a single test run. Also no non-native resolutions supported the monitor's native 144 Hz refresh rate and so will have higher input lag, which is not great.

Update 12/11/2017: When the monitor's 'Game -> Refresh Rate' setting is set to 60 Hz, the 'Low Input Lag' setting is no longer greyed out and the 60 Hz input lag becomes consistently low. The test result has been updated. When using the monitor at 60 Hz without FreeSync, such as when using an Xbox One X, we recommend setting 'Game -> Refresh Rate' to 60 Hz and 'Low Input Lag' to 'On'.

The monitor has a sharp 1440p resolution and a large 27" size, which are great for almost all usages. The Samsung C32HG70 has the same 1440p resolution but a larger 32" size, which is better but also more expensive.

The monitor's EDID does accept a 4k @ 60Hz @ 4:4:4 signal over HDMI, and will downscale it to its native resolution of 2560x1440. See more information here.

Unfortunately, when connected to an Xbox One, the CHG70 does not support 1440p @ 120 Hz.

Features

The Samsung CHG70 has a well-organized OSD that's easy to navigate with the joystick control on the back of the monitor. The OSD has most of the standard monitor features such as adjustable image and color settings, as well as a 'USB Super Charging' mode for devices that support quick-charge and an 'Eye Saver Mode' for night time viewing. The monitor's firmware can also be upgraded from a USB drive inserted in USB port 1, which is useful because early firmware versions don't support the monitor's full FreeSync range.

Additional Features

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.

On-Screen Display (OSD)
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 actually 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.

Differences between Sizes and Variants

The CHG70 we bought is the 27" model (Samsung C27HG70). It is 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 will update the review. Note that some tests such as the gray uniformity may vary between individual units.

Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

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 freesync monitors and the best 1440p 144Hz monitors.

Gigabyte Aorus AD27QD

The Samsung CHG70 and the Aorus AD27QD use different panels, and each is better for certain uses. The CHG70 uses a VA panel, which is better suited for dark room viewing, but the image degrades when viewed at an angle. The AD27QD, on the other hand, uses an IPS panel, and the image remains accurate when viewed at an angle. That said, it produces grayish blacks and generally doesn't look as good in a dark room.

LG 27GL850-B
SEE PRICE
Amazon.com

The two monitors use different panel technologies, each with advantages and disadvantages. The LG 27GL850-B hs an IPS panel that allows wider viewing angles, whereas the Samsung CHG70 has a VA panel and offers better dark room performance thanks to the much better contrast ratio and local dimming feature. The LG has slightly faster response time, but the Samsung has a black frame insertion feature that can help make motion look crisper.

Dell S3220DGF

The Samsung CHG70 is slightly better than the Dell S3220DGF. The Samsung has an optional black frame insertion feature to help the appearance of motion, and a better ergonomic stand that allows you to place the monitor in a comfortable position with ease. The Dell, on the other hand, displays more uniform blacks, which is important when working in a dark room.

ASUS ROG Swift PG279Q

If you want a monitor for office use, then the ASUS ROG Swift PG279Q is a better choice due to its wider viewing angles. On the other hand, if you're playing a lot of HDR games, the Samsung CHG70 should be your choice as it supports HDR and will offer a decent HDR gaming experience. If plain gaming is your thing, then both monitors are excellent. They also perform very similarly in other uses without one being significantly better than the other.

LG 32GK850G-B

The Samsung CHG70 is significantly better than the LG 32GK850G. The Samsung CHG70 supports HDR content so you can enjoy HDR games, and supports FreeSync for a tear-free gaming experience. The CHG70 has a Black Frame Insertion feature that helps make the image crisper. The LG 32GK850G has a larger screen so you can see the details of your screen more comfortable, and supports G-SYNC, which is great if you have an NVIDIA compatible card.

7.8 Mixed Usage

Very good monitor for a mixed usage. The Samsung CHG70's 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. Its native support for HDR and wide color gamuts great too. Unfortunately, its viewing angles are quite narrow, making it less useful in more communal environments.

7.4 Office

Decent monitor for use in an office. The Samsung CHG70's high brightness and good handling of reflections mean it won't have any difficulty dealing with the harsh lighting of most offices. Its larger size and high resolution are also quite useful for productivity, but its slightly bulky space and narrow viewing angles make it less practical for sharing with neighboring co-workers.

8.5 Gaming

This is a great gaming monitor. It has very little input lag, and its high refresh rate, image flicker and relatively quick response times make for very sharp and fluid motion. Its HDMI 2.0 input makes it a particularly good choice for those that also want to use their monitor with an Xbox One X.

7.7 Multimedia

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 almost entirely, 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

Good monitor for media creation tasks. The monitor supports the DCI-P3 color gamut, which means it is 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 very wide color gamut helps make HDR game 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.
