How to check the color difference on the monitor

If seen from the top/bottom/left/right, due to the panel characteristics, there can be a brightness or color difference, so it is a normal product.
Adjust the monitor's height, angle adjust and so on to set the correct visual angle.
(Height and angle control functions and so on vary depending on the model.)
LCD monitor is composed of multiple thin layers, thus depending on the location, there can be a fine thickness difference.
Due to the thickness difference, there is a difference in light penetration rates, which in turn leads to a different color seen from the top/bottom/left/right/diagonal line, thus it is a normal product.
