What size monitor should I buy? A few years ago, 21.5 inches was still entry-level, but now 21.5 inches is a bit small. Data display sizes have been upgraded and size centralization has become increasingly apparent. The average monitor panel size in 2019 was 23.7 inches, an increase of 0.5 inches year-on-year.

Therefore, buying a monitor of around 23.8 inches is now the entry-level configuration. Of course, a monitor of this size is not expensive, and many products can be purchased for only 700 to 800 yuan. The better upgrade products are basically over 1,000 yuan. For installation, the budget for the monitor is not high. After all, the price of a 16G memory is several hundred yuan.

Sales data in 2019 show that 23.8-inch surpassed 21.5-inch for the first time, with a market share of 25.5%, while 21.5-inch’s market share dropped to 21.5%; it can be seen that consumers also like this size very much. The 21.5-inch screen has become as marginalized as the 17-inch screen.

Among them, 27-inch is the favored size for mid-to-high-end products, and its market share continues to increase. In 2019, the market share reached 13.9%; the market share of the mid-to-large size segment (23.8 inches and above) reached 52.5%, and the concentration of mainstream sizes has increased. So those who want to upgrade can choose 27 inches.

For 27-inch products, 1080P resolution is not enough, and 4K resolution is higher than 27-inch products and appears denser, so 2K resolution is very suitable. The author recommends two major focuses on upgrading monitors in 2020: 27-inch and 2K resolution, which is the most cost-effective.
