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.
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.
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 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.
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 very 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.
The CHG70 has a simple design, with a wide v-shaped stand that supports the monitor well, but has a relatively large footprint. There's not much in the way of cable management, but the stand has good ergonomics, and it can also be VESA mounted.
The Samsung CHG70 has a similar stand base to their other monitors, like the Samsung JG50, but without the glossy finish found on more recent models. It has a relatively large footprint, but it feels stable and provides good support.
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 rear of the monitor looks stylish. It's made of plastic but has a matte finish. Where the stand arm joins the monitor, there's a ring of LEDs that can pulse during use (see here). It's possible to mount the monitor using the included adapter.
Unfortunately, there's just a small clip on the back for cable management.
The borders look sleek and are thin. The sides are made of a silver colored plastic, which looks good.
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 it's 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).
The build quality of the Samsung C27HG70 is great. The unique design feels well-constructed, despite the plastic parts.
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.
Great SDR peak brightness. While it does fluctuate slightly depending on screen content due to its local dimming, the monitor easily gets bright enough to suit most environments. This also helps it handle reflections from lights or windows.
Decent HDR peak brightness. HDR isn't any brighter than SDR, which is disappointing. It isn't bad, but it doesn't get bright enough to define specular highlights properly and give a very significant HDR effect.
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.
Poor vertical viewing angle, which is expected for a VA monitor. Unfortunately, its blacks shift rapidly, causing visible black clouding in the corners of the screen even with slight head movements. This is most distracting when viewing letterboxed content.
The Samsung CHG70 has excellent gray uniformity. There's very little dirty screen effect, and the corners are only slightly darker than the rest of the screen. In near-dark scenes the uniformity is good, but there are some horizontal bands.
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.
Out of the box, the Samsung C27HG70 has great accuracy. Most people won't notice any issues with colors or shades of gray. Gamma doesn't quite follow the sRGB target curve, though, as everything is displayed a bit darker than it should be.
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.
Good SDR color gamut, the Samsung CHG70 has no issues covering most of the essential sRGB color gamut. It has great coverage of the wider Adobe RGB color space as well.
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.
Very good wide color gamut, with excellent coverage of the DCI P3 color space used by the majority of current HDR content.
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.
Like most monitors with VA panels, the C27HG70 doesn't show any signs of temporary image retention.
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.
Excellent low input lag, making this a great monitor for gaming. When gaming at 60Hz, we recommend setting the Refresh Rate setting to '60Hz' on the monitor, and enabling the Low Input Lag setting.
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 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 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.
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.
The CHG70 we tested was manufactured in August 2017.
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. See also our recommendations for the best mice and the best keyboards.
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.
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.
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.
The Samsung CHG70 is much better than the Samsung CJG50. The CHG70 has much better ergonomics, a faster response time, and it supports FreeSync for a nearly tear-free gaming experience. The CHG70 also supports HDR and is a bit brighter.
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 which make it better for gaming. The Samsung CHG70 also has better blacks.
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.
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.
The Samsung CHG70 and ASUS VG279Q use different panel technologies, each with their advantages and disadvantages. The CHG70 looks best in a dark room, it supports HDR, and has a higher native resolution. The VG279Q, on the other hand, has better ergonomics and the IPS panel delivers wide viewing angles, but it doesn't look as good in a dark room.
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.
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.
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 and the Acer Predator XB271HU have similar overall performance. They have different panel types, however, so each one is better than the other in different aspects. The Samsung CHG70 supports HDR and performs decently in that mode, and it also supports local dimming that makes blacks look deep in a dark room. The Samsung CHG70 has better reflection handling and a curve profile that some people like. The Acer Predator XB271HU, on the other hand, has better ergonomics so you can easily position it to your liking. The Acer has wider viewing angles due to its IPS panel, and thus it's easier to share your work.
The Samsung CHG70 is better than the AOC AGON AG271QX. The Samsung has better native contrast than the AG271QX, important for dark room viewing, although the AG271QX has better black uniformity. The AG271QX has a slightly faster response time, but the CHG70 has an optional black frame insertion feature that can improve motion by reducing persistence blur. Finally, the CHG70 supports HDR and can display a wide color gamut.
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.
