The Samsung C27F398 is a decent 27" VA monitor that delivers okay picture quality. It has excellent low input lag, very good motion handling, and it supports FreeSync, which is great for gaming. It has a very good native contrast ratio, that delivers good dark scene performance. Unfortunately, it has a fixed stand that can't be easily adjusted to an ideal viewing position, and it can't get very bright.
The Samsung C27F398 has a decent, but basic design. Overall it is similar to the LG 24MP59G. It can be VESA mounted, which is nice as the stand has only basic ergonomics, and there is no cable management. It has decent build quality, but is made of plastic and feels cheap. Overall, you shouldn't have any issues with it though.
The stand has a very large footprint, similar to the CHG70. When the monitor is nudged there is little wobble, but the stand doesn't feel very sturdy.
The back of the Samsung C27F398FWN is very plain. There are grooves across the entire back, and all of the inputs face out of the back, which isn't ideal if VESA mounted. There is no cable management.
Decent build quality overall. It is pretty basic, similar to the LG 24MP59G, and although it is entirely made of plastic there shouldn't be any issues with it.
The Samsung C27F398 delivers decent picture quality. It has a very good native contrast ratio, which is great, but it has only mediocre black uniformity. It has excellent coverage of the sRGB color space, but less than ideal coverage of the wider Adobe RGB color space. Unfortunately, the CF398 isn't very bright and has a hard time overcoming glare in a bright room, and the image degrades when viewed at an angle.
There is no local dimming feature on this monitor. The video is for reference only.
Decent peak brightness, slightly dimmer than the larger CF791. The brightness remains constant, regardless of scene changes, which is great.
HDR is not supported on this monitor.
Disappointing horizontal viewing angles, but better than most VA monitors that we've reviewed with the exception of the Sceptre C325W. The brightness drops to half of the peak brightness at about 52°, which is decent, and colors degrade gradually when viewed off-center.
Decent vertical viewing angles, again, better than most VA monitors. Unfortunately, the black levels increase rapidly when viewed even slightly off center.
The Samsung C27F398 has excellent gray uniformity. The center of the screen is a bit brighter than the edges, but this shouldn't be noticeable under most viewing conditions, and there is very little dirty screen effect. In near-black scenes the uniformity is even better, and there are no issues.
Mediocre black uniformity. There are a few flashlighting spots that are noticeable when viewed from directly in front. The black uniformity appears noticeably worse when viewed at an angle, due to the bad black levels at an angle.
The Samsung C27F398FWN has mediocre accuracy out of the box. The color temperature is very warm, and the color error is high enough that most people will notice it. White balance error is even higher, and gamma doesn't follow the target curve.
After calibration, the CF398 is nearly perfect. Gamma follows the target curve nearly perfectly, and the color temperature is almost spot on the 6500 K target. Color and white balance errors are nearly entirely corrected, but there is still a high blue error, but this shouldn't be very noticeable.
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.
s.RGB Picture Mode: Custom (calibrated)Adobe RGB Picture Mode: Custom
Excellent SDR color gamut. Coverage of the smaller sRGB color space is nearly perfect, but coverage of the wider Adobe RGB color space is less than ideal for professional photo and video editing. Unfortunately, the color gamut isn't as wide as that of the MSI Optix G27C.
s.RGB Picture Mode: CustomAdobe RGB Picture Mode: Custom
Excellent color volume. In the s.RGB color space it can fill out the gamut at most brightness levels, but it can't produce dark colors very well, and like most monitors, it can't produce very bright saturated blues. Adobe RGB coverage is limited by the color gamut, and isn't ideal for professional video editing.
HDR is not supported on this monitor.
HDR is not supported on this monitor.
Perfect image retention performance, as there was no residual image even immediately after showing our high contrast test image for 10 minutes.
Great gradient performance, there is some banding noticeable in darker shades, but this shouldn't cause any issues under normal viewing conditions.
Perfect color bleed performance, as there is no error whatsoever.
The Samsung C27F398 has very good motion handling. It has an excellent response time, and there is only slight motion blur behind fast moving objects. The backlight is completely flicker-free, which is great, but it does not have an option to add flicker in order to improve motion clarity. It has a native 60 Hz refresh rate, which may be disappointing to some gamers, however, it can easily be overclocked to 72 Hz, simply by enabling the FreeSync mode in the monitor's settings, even when connected to a computer that isn't compatible with FreeSync.
The CF398 has an excellent response time. It has an adjustable Response Time setting, with three modes, and we recommend the 'Fastest' option. In this mode, there is some overshoot in a few transitions, and a small amount of undershoot in a few down transitions, but neither of these are significant enough to be noticeable under most viewing conditions.
Although the monitor's refresh rate can be increased to 72 Hz, the response time was measured at 60 Hz. At 72 Hz the response time is probably a bit better.
The CF398 is completely flicker-free, which is great. Unfortunately, it does not have an option to add flicker in order to improve motion clarity.
The Samsung C27F398 has a standard 60 Hz refresh rate, and it supports FreeSync, which is great. The refresh rate can be changed to 72 Hz without overclocking, and there are two ways to do this:
In all cases, 72 Hz is displayed properly with no dropped frames.
The Samsung C27F398 has excellent low input lag that should please most gamers. Unfortunately, although the 27" screen is a good size, the 1080p resolution isn't ideal for multitasking, and it doesn't provide a very immersive gaming experience. It has only 2 inputs: 1 HDMI port and 1 DisplayPort, so it isn't great for connecting multiple devices or for legacy devices with only analog outputs.
Lowest input lag possible at the center of the screen, when the monitor is displaying an alternative resolution at its native refresh rate. The non-native resolution tested depends on the native resolution of the monitor, following this pattern unless otherwise specified in the Input Lag text:
|Native Resolution||Non-Native Resolution Tested|
Excellent low input lag when gaming at the native 1080p @ 60 Hz, and even lower input lag when in FreeSync mode at 72 Hz.
The Samsung C27F398FWN has a good sized, 27" screen, but most people will probably be disappointed by the 1080p FHD resolution, as it isn't great for multitasking.
There is a single HDMI and a single DisplayPort input, but no VGA or DVI. There is a 3.5 mm port that is a headphone port with adjustable volume using the OSD volume setting.
The Samsung C27F398FWN has very few additional features. It does not have internal speakers and it does not support HDR. There are no options to improve gaming performance, but there is a Game Mode that adjusts the contrast and brightness to make it easier to spot other players hiding in the shadows.
The CF398 uses a joystick, similar to the CHG70 and to LG monitors. It is very intuitive, and makes the OSD very easy to navigate.
We tested the 27" CF398 (LC27F398FWNXZA), which is the only size available. There are other models available with similar specifications, but we don't know how they perform.
If someone comes across a different type of panel or if their Samsung CF398 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.

The CF398 we reviewed was manufactured in July 2018.
The Samsung CF398 is a decent entry-level monitor. There are much better monitors out there if you are willing to spend even a little bit more. Check our recommendations for the best 27 inch monitors and the best 1080p monitors.
The Samsung CF398 is much better than the Sceptre C325W. The Sceptre is a bit brighter, and has a slightly better native contrast ratio, but worse black uniformity. The CF398 has a much better response time with significantly less motion blur, and it supports AMD FreeSync. The CF398 also has lower input lag.
The Samsung CF398 is better than the MSI Optix G27C for most uses, but some people may prefer the Optix for gaming. The Optix is a bit brighter, and has slightly better native contrast, but worse black uniformity. The CF398 has wider viewing angles and better black uniformity. For gaming, the CF398 has a faster response time, but the Optix has a much faster refresh rate and lower input lag.
The Dell P2417H is a 24" IPS monitor, whereas the Samsung CF398 is a VA monitor. Generally, the P2417H is better than the CF398, but the CF398 is a bit better in some cases. The P2417H has wide viewing angles and a much better, fully adjustable stand, making it a more versatile choice for most people. The CF398 on the other hand has a faster response time, so motion looks clearer with less blur, and it supports FreeSync VRR.
The HP 27f and the Samsung CF398 use different types of panels, each with their own strengths and weaknesses. The 27f has an IPS panel, so the image remains accurate when viewed at an angle. The CF398 has a VA panel, and it delivers better overall dark room performance. The HP 27f also has a slightly faster refresh rate, although it isn't a significant difference.
The Acer XF251Q is a 25" TN monitor, whereas the Samsung CF398 is a VA monitor. The XF251Q has better motion handling, thanks to a faster response time. The XF251Q is a bit brighter, but the CF398 has much better native contrast, so it looks better in a dark room.
