The Samsung JG50 is a decent 1440p monitor. It has a great refresh rate and outstanding low input lag, great for gaming. The VA panel delivers deep blacks, can get bright enough for most rooms, and reflections are reduced significantly, so there shouldn't be any issues using it in a bright room. Unfortunately, this monitor doesn't support any of the variable refresh rate technologies, and the image degrades when viewed at an angle. The JG50 also has poor black uniformity, and a fixed stand that can make the monitor difficult to place in an ideal viewing position.

The Samsung C27JG50 has a decent design. The stand supports the monitor well, but does wobble a bit when nudged. It has a very similar design to the Samsung CHG70, but unfortunately, the stand is fixed and has terrible ergonomics, so it might be difficult to place it in an ideal viewing position unless you VESA mount it. The monitor has decent build quality, with no obvious issues.

Stand

18.3" (46.5 cm)

The stand has a very similar design to the CHG70's, but with a glossy finish that tends to attract fingerprints a bit more.

Unfortunately, the Samsung LC27JG50QQNZA has terrible ergonomics. There is no height adjustment, it can't swivel, and it has a very narrow tilt range.

Back
Wall Mount : VESA 75x75

The back of the monitor is very plain. The entire stand can be removed, which is great if you are planning on VESA mounting it, but there is no quick release.

Borders
Borders

The borders are very sleek and thin, and they aren't very distracting.

Thickness
Thickness (with stand)
:

Thickness (without stand)
:
3.7" (9.4 cm)

Due to the curvature of the screen, the CJG50 appears thicker from the side than most monitors. When VESA mounted it sticks out quite a bit.

7.0 Build Quality

The Samsung LC27JG50QQNZA has decent build quality, slightly better than the CF398, but slightly worse than the UE590. The stand is difficult to adjust, as the tilt is very tight. It does feel sturdy though, and there are no obvious issues with it.

6.3

Picture Quality

The Samsung JG50 delivers mediocre picture quality. It has a great contrast ratio, one of the best we've measured on a monitor. This monitor also has good peak brightness, great reflection handling, and excellent gray uniformity. Unfortunately, it has bad black uniformity, which isn't ideal for viewing dark scenes in a dark room, and like most VA monitors, the viewing angles are poor. This monitor does not support HDR.

Poor vertical viewing angles, typical of monitors with VA panels. Even slightly off center, the image quickly washes out. Colors lose accuracy at a narrow angle, and the brightness gradually decreases as you move off-angle. For better viewing angles, check out an IPS monitor, like the Gigabyte Aorus AD27QD.

Out of the box, the Samsung LC27JG50QQNZA has very good accuracy. There are some inaccuracies in shades of gray, but most people won't notice it. Colors are little less accurate, and there are noticeable inaccuracies in many shades. Gamma does not follow the sRGB target curve at all; very dark scenes appear quite a bit darker than they should, and bright scenes are over-brightened a bit.

After calibrating, the Samsung JG50 has excellent accuracy. Overall, colors are much more accurate, but some people might still notice some inaccuracies with pure blues. Gamma follows the sRGB target curve almost perfectly, but some bright scenes are still over-brightened a bit.

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

Great SDR color gamut. It's able to display most of the standard sRGB color space, but like many monitors, can't display the wider range of greens and blues in the Adobe RGB color space. This is fine for desktop use and gaming, but not ideal for professional photo or video editing.

There is no visible color bleed, which is great.

8.0 Reflections

Great reflection handling. In an average lit room there are almost no noticeable reflections, and you shouldn't have any issues.

8.1

Motion

The Samsung CJG50 has great motion handling. It has a great response time, so there is only a short motion trail behind fast-moving objects. The backlight is completely flicker-free, which is great, but there is no option to add flicker in order to improve the appearance of motion. It has a great 144Hz refresh rate, but unfortunately, it does not support any of the variable refresh rate technologies, like AMD's FreeSync.

The CJG50 has an excellent response time, delivering clear motion with a very short blur trail behind fast-moving objects. Like the CHG70, the 0-20% transition is a lot slower than the others, so some ghosting may appear in very dark scenes.

There are a few different response time settings. There is very little difference between them, which is a bit strange and unexpected, but we don't know why. Since there is no overshoot in any of them, and very little difference, we recommend the 'Response Time Fastest' setting.

The Samsung C27JG50 has a great 144Hz refresh rate. Unfortunately, it doesn't support any of the variable refresh rate technologies, like FreeSync or G-SYNC.

Like the CHG70, the refresh rate has to be set from the monitor's OSD (as shown here), as well as your source device. If the refresh rate setting does not match what the source is sending, input lag is significantly higher.

HDMI port 1 is limited to 1440p @ 60Hz, as it is an HDMI 1.4 port. 1440p @ 144Hz is only supported on HDMI 2, or DisplayPort.

9.1

Inputs

The Samsung JG50 has oustanding low input lag, great for gaming. It also has a great native resolution, which allows you to see more fine details in your favorite games, and is great for multitasking. It has a decent selection of inputs, but it has no analog inputs for older devices.

The Samsung LC27JG50QQNZA has outstanding low input lag, even at 60Hz, great for console gaming.

Like the CHG70, the refresh rate has to be set from the monitor's OSD (as shown here). If the refresh rate setting does not match what the source is sending, input lag is significantly higher.

HDMI port 1 is limited to 1440p @ 60Hz, as it is an HDMI 1.4 port. 1440p @ 144Hz is only supported on HDMI 2, or DisplayPort.

6.9 Mixed Usage

Decent monitor for most uses. It has a good amount of screen real estate, great for multitasking. There is very little input lag, and the response time is fast, great for gaming or multimedia, but it doesn't support any advanced gaming features, like any of the variable refresh rate technologies. This monitor does not support HDR.

6.7 Office

Decent monitor for office use. It has great screen real-estate, perfect for multitasking, it can get bright enough for most rooms, and has great reflection handling. Unfortunately, it has poor viewing angles, and the stand has terrible ergonomics, so it can be difficult to place the monitor in an ideal viewing position.

7.6 Gaming

Overall, this is a good monitor for gaming. It has a fast response time, delivering clear motion with only a short blur trail behind fast-moving objects. It also has exceptional low input lag for a responsive gaming experience. Unfortunately, it lacks any advanced gaming features, like virtual crosshairs, and it doesn't support any of the variable refresh rate technologies.

6.7 Multimedia

Decent monitor for multimedia. It has a great native contrast ratio, so blacks don't look gray in a dark room, and it has a great amount of screen real-estate. It also has good peak brightness, and great reflection handling, so you shouldn't have any issues using it during the day in a bright room. Unfortunately, it has bad black uniformity, and the poor viewing angles make it a poor choice for watching the latest YouTube trends with your friends.

6.6 Media Creation

Overall, this is a decent monitor for media creation. It has great screen real-estate, so you can see more of your project at once, and there is very little input lag. Unfortunately, it has poor viewing angles, and the stand has terrible ergonomics, so it may be difficult to adjust it to an ideal viewing position without VESA mounting it.

5.4 HDR Gaming

The JG50 does not support HDR. For a decent HDR gaming monitor, check out the Samsung CHG70 instead.
