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.

7.7 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.

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.

Design

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 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.

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.
