It has many settings for color calibration. Separate hue and saturation for yellow, cyan, magenta, red, blue, etc. HOWEVER, it has crazy bleed. Nice colors and viewing angle but in dark content it has a lot of bleed.

The image quality is excellent. I use it with DVI-D as a computer monitor and with HDMI as an external TV receiver. For this dual use of PC & TV, I do not recommend it for two reasons:
1) The built-in speakers can barely be heard (like having headphones connected at high volume).
2) The switch from one input source to another does not happen automatically, so the button on the screen needs to be pressed every time.

The way I dealt with the first issue is by connecting the audio output of the monitor to external speakers, while the audio input of the monitor receives signal from the PC's audio output. Therefore, both the computer and the TV produce sound through the external speakers.

For the second problem, I have not found a solution and I am considering contacting the dealership in case it is defective.

However, I would only buy it again as a monitor because, in addition to the very good image quality, I really liked its stand, which has all kinds of adjustments (tilt forward-backward, rotation for the person next to you to view, rotation for portrait-landscape, height).

And one last thing that concerns me is that once or twice a week, a small usually temporary section of the screen distorts for 1-2 seconds, but only when connected to a computer (DVI-D) and not to a TV (HDMI).

Update 8/4/2020: The distortions have not appeared for at least a month, so I assume it was probably a connection or computer issue rather than a monitor issue.
