Zhuo Yi and NEC are really top-notch in professional graphic displays, such as CG series of Zhuo Yi and PA series of NEC. Although the LCD panel is not produced by itself, the quality control is extremely strict. Some LCD panel manufacturers, such as LG, also use Zhuo Yi's own LCD panel as their slogan. Zhuo Yi and NEC's top professional monitors rely on strict quality control and color adjustment to achieve extremely low color difference, slight light leakage, accurate contrast and wide color gamut. Of course, the price is also top-notch, and the price of the same size monitor is fixed, which is generally adopted by professional enthusiasts and large photography, design and printing industries. Although both companies have civilian-grade monitors and strict quality control, their market share is not very high. In general commercial solutions, Taiwan Province TPV OEM monitors and Dell monitors account for a large share. Generally speaking, Zhuo Yi and NEC are the best brands, but brands such as Dell also have their own advantages in terms of cost performance and productivity transformation.
