3. I'm mirroring my laptop screen. (I don't like joint screens.)
4. I'm using HDMI cable.
Most of the time the monitor works great: no flickers; no black dots; no any other noticeable issues. However, sometimes, the monitor would become "half black and half white": the left half of the monitor becomes completely pure white color, and the right half becomes completely pure black color. This may remain for 0.5 ~ 1 second and then the monitor becomes normal again.
The time this happens seems to be random but it has happened like 10 times since I bought it. I tried a different HDMI cable but the issue still happens.
