Pro Great picture quality
The Samsung uses a 10-bit color display panel, resulting fantastic picture quality. It can reproduce more than a billion colors, compared to the 16 million colors of 8-bit panels. The color saturation and accuracy easily compete with more expensive screens, although they are not precise enough for photo-centric work. Contrast levels are average, but the monitor is brighter than other monitors in its price group.
Pro Suitable for watching in bright setting
The brightness measures up to 300 nits after calibration and the matte screen reduces glare, making it easy to view the screen in bright conditions
Pro Good contrast ratio
It delivers a standard contrast ratio of 1:1000, although when properly calibrated, the contrast ratio goes down slightly.
Pro Excellent response time for gamers
This screen offers an excellent response time of only 1 ms, compared to the 5 ms (or more) of other monitors in this price range. Input lag measures at 15 ms, which is second only to dedicated gaming monitors with 10 ms response times.
Pro Multiple inputs (and the option to watch them simultaneously)
This screen's connectivity consists of two HDMI 2.0 ports and one DisplayPort 1.2., which is enough for most users. Samsung offers picture-in-picture and picture-by-picture modes. Meaning that you can view two inputs side by side or one can be scaled down to a small window that you can place on one of the corners.
Pro Good colors
The screen’s 10-bit panel covers 97% of the sRGB color spectrum which is a respectable result for a budget monitor. For professional use, you will have to look for something more accurate. Color saturation and accuracy is excellent and can compete with higher priced models.
Pro Compact, stable and aesthetically pleasing stand
The stand takes little place and has a metallic finish and is quite stable, even if at first this doesn’t seem to be the case
Pro Comfortable on eyes even after prolonged use
This monitor offers a flicker-free backlight, which reduces strain on your eyes. It also includes a setting that reduces the amount of blue light in the screen, making the picture look softer and facilitates nighttime use.
Pro Elegant and minimal look
This monitor is finished in a black plastic with metallic look borders and looks elegant and minimal.
Cons
Con Bad viewing angles
Since it's a TN monitor, it has worse viewing angles compared to IPS displays.
Con Bad refresh rate
At 3840 x 2160 it's max 30Hz and at 1920 x 1080 it's max 60Hz.
Con Extremely limited Freesync range (54-64hz)
The Freesync feature is almost useless as the range is actually 54-64hz instead of at least 40-60hz.
And no, even using CRU won't help, as any modification to the freesync range will result into the monitor turning complete white (stuck) eventually after awhile.
Con Poor viewing angles
It uses a TN panel which generally has terrible viewing angles. Color shifting occurs at 40 degrees. And even though Samsung’s proprietary “MagicAngle” helps to improve it, there are plenty of other monitors offering better viewing angles.
Con Limited flexibility
The monitor does not offer much flexibility options as it only can be slightly tilted, but you cannot change the height or swivel it at any direction. There is a Vesa mount in the back so you can attach it to a more flexible stand or wall mount.
Con No USB ports
There are no USB ports found on this screen, so there is no possibility to watch media from external storage directly or use the screen as an USB hub.
Con Accessible navigation joystick
Navigation is done with a joystick in the left bottom side of the screen and is easily accessible.
Con Cheap plastic on the back
The plastic on the back of the screen feels a bit cheap.
Con Very limited screen position control
The monitor can only be tilted by 20 degrees, and no swivel or height changing is available, so is very limited regarding screen position control.
