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.

Weight (with stand) : 13.6lbs (6.2 kg)

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.

Stand

Width : 20.3" (51.6 cm)
Depth : 12.1" (30.8 cm)

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.

7.1 Ergonomics
What it is: How much the position of the screen can be adjusted to match the viewing preference of the user.
When it matters: All usages, but especially office and gaming use.

Height Adjustment : 5.7" (14.4 cm)
Switch portrait/landscape : Yes
Swivel Range : -15° to 15°
Tilt Range : -15° to 5°

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.

Back

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 pulse during use. It is possible to mount the monitor using the included adapter.

Borders
Samsung CHG70 Borders picture
Borders : 0.6" (1.5 cm)

The borders look sleek and are thin. The sides are made of a silver colored plastic, which looks good.

Thickness
Samsung CHG70 Thickness picture
Thickness (with stand) : 11.2" (28.5 cm)
Thickness (without stand) : 2.5" (6.4 cm)

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
What it is: How well built and sturdy the monitor is, and how good the materials used to build it are.
When it matters: All usages.
Score components: Subjectively assigned
Samsung CHG70 Build Quality picture

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

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.

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
What it is: The lights behind the LCD layer adapt to the picture displayed, improving the contrast ratio.
When it matters: Dark scenes viewed in a dark room.
Score components: Subjectively assigned
Local Dimming
What it is: Whether it has a feature that controls the LEDs behind the LCD layer, to match the picture and darkens the dark portion of it.
When it matters: On LED TVs only. Dark scenes viewed in a dark room.

Yes
Backlight
What it is: Configuration of the lights of the backlight.
When it matters: Effectiveness of the local dimming.
Good value: Full-array/direct lighting is better for local dimming. As for the uniformity of the screen, it depends on the implementation. Some edge-lit monitors have more uniform blacks than some full-array monitors.
:
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.

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.

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.

Motion

Score components:

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
What it is: The performance of the pixel response time. Poor response time causes trails to follow moving objects. Response time is one of a few sources of motion blur.

:
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.

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.

VRR Supported Connectors : DisplayPort, HDMI

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'.

BFI frequency tested: 144 Hz

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'.

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.

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.

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 HDR gaming monitor with a high refresh rate and better than average picture quality. 

LG 27UK650

If you've got a bright office and work closely with others, the LG 27U650 is a better choice, but if you play games in a dark room sitting directly in front, then the Samsung CHG70 is a better choice. The LG 27UK650 has better resolution and much better vertical and horizontal viewing angle which make better for office use. On the other hand, the Samsung CHG70 has better refresh rate and input lag and which make it better for gaming. The Samsung CHG70 also has better blacks due to better contrast and local dimming support and better HDR performance. 

ASUS ROG PG279Q

If you want a monitor for office use, then the ASUS ROG PG279Q is a better choice due to its wider viewing angles. On the other hand, if you are 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 usages without one being significantly better than the other.

LG 34UC79G-B

The Samsung CHG70 is better than the LG 34UC79G-B, unless you plan on sitting close to the monitor. The Samsung CHG70 has a VA panel, which is better for dark room viewing, and supports HDR for the best gaming and multimedia experience. The LG 34UC79G-B uses an IPS panel, which has much wider viewing angles, and so is great if you plan on sitting close to the monitor as the image quality won't degrade towards the edges.

Samsung CHG90

The Samsung CHG70 is better than the Samsung CHG90. The CHG90 has a much larger screen but with lower pixel density. Also, the CHG90 has a better native contrast ratio and black uniformity so it can display better blacks in a dark room. The CHG70 has better ergonomics to help you position it to your preferences and is flicker free. In almost all other aspects, the monitors behave very similarly.

LG 32UD59-B

The Samsung CHG70 is better than the LG 32UD59-B. The Samsung CHG70 has better ergonomics and is easier to position to your preference, and this is great for every usage. The Samsung has a local dimming feature, better color gamut, and support for HDR. At the same time, it has much better motion handling and is packed with gaming features so you will enjoy gaming more on the Samsung. On the other hand, the LG 32UD59-B is marginally better for office as it has more screen area and can display more detail due to the higher resolution.

Acer Predator X27

The Acer Predator X27 is a bit better than the Samsung CHG70, unless dark room performance is an important factor. The Predator X27 is much brighter than the CHG70 and has wider viewing angles. The X27 offers a better HDR experience, highlights stand out more in some scenes and colors are more saturated and vibrant. The VA panel in the CHG70 delivers deeper blacks, and better black uniformity, but worse viewing angles. The CHG70 also has better low input lag.

Samsung CF791

The Samsung CHG70 is much better than the Samsung 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 will enjoy it in every usage. The CF791, on the other hand, is larger, giving you more screen area and more resolution to work with.

Dell U2718Q

The Dell Ultrasharp U2718Q is better than the Samsung CHG70, unless your main usage is for gaming or for dark room viewing. The Dell U2718Q has wider viewing angles and a higher native resolution, so you can see every detail. The CHG70 has a higher native contrast ratio, so it performs better in a dark room. The Samsung also has much better motion handling thanks to the much higher 144 Hz refresh rate and AMD FreeSync support.

LG 29UM69G-B

The Samsung CHG70 is a much better monitor for every usage than the LG 29UM69G-B. The LG 29UM69G has better viewing angles due to its IPS panel, so it keeps its picture quality when you look from the side. On the other hand, the Samsung CHG70 has better ergonomics, better native contrast ratio and supports HDR. Finally, the Samsung CHG70 has slightly better input lag and features that make it better for gaming.

HP OMEN 27

The Samsung CHG70 is a much better monitor than the HP OMEN 27 in almost every usage. 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 TN panel and a very fast pixel response time that leaves 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.

Acer Predator XB271HU

The Acer Predator XB271HU is an IPS gaming monitor with excellent motion performance but worse image quality. It doesn't support HDR and blacks appear gray when viewed in a dark room, but the image remains accurate when viewed at an angle. If you want the most accurate image from any angle, then the Acer Predator XB271HU is a better choice, but otherwise, go with the Samsung CHG70.

Dell S2716DG

The Dell S2716DG is a 144Hz gaming monitor with a TN panel. It has worse picture quality as blacks appear gray in a dark room and when viewed from in front the top and bottom of the screen shift colors, but motion handling is excellent due to the very fast response time and G-Sync support. If all you care about is the fastest motion at 144Hz then go with the Dell, but otherwise, go with the Samsung for better picture quality and HDR support.

LG 27UD68P-B

The LG 27UD68P-B is an IPS monitor with decent picture quality and a very high pixel density 4k screen. This provides an extremely sharp image, but the picture quality isn't as good as the Samsung CHG70 as it doesn't support HDR and blacks appear gray in a dark room. Motion handling also isn't as good due to the lower refresh rate 60Hz panel and higher input lag. For gaming or HDR the Samsung CHG70 is a better choice, but if you care more about screen space, then go with the LG 27UD68P-B.

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.
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.
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.
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.
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.
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.
