Is the portable monitor useful? Will digital enthusiasts regret it after buying it? Listen to her opinion.

I always think that the so-called "portable monitor" and "portable display screen" on the market now are just a screen, without any built-in system or any intelligent function, so what's the point of buying it? Spend hundreds of thousands of dollars to buy a big screen without any system functions?

Recently, my friend bought a portable monitor and I laughed at her. Apart from the size advantage, what's the difference between this thing and my desktop monitor? It's really an IQ tax. As a result, my friend laughed that I didn't understand, and showed me her good opinions and evidence on the portable display screen. Let's listen to what he said:

1. First of all, what she said is the same as what I said. First of all, this thing takes advantage of its size. It is very portable and can be taken away at any time. Desktop monitors obviously can't. Taking it away at any time means being able to participate in mobile office.

2. Desktop monitors usually only have VGA, DVI, HDMI and DP interfaces, while portable monitors also have Micro HDMI and Mini HDMI. Most importantly, portable monitors usually come standard with full-featured Type-C and support Type-C video output, which means that as long as your mobile phone supports Type-C video output (almost all supported by Huawei, which is awesome in China), or game devices such as PS5 and Switch, or mini host, you can make your portable monitor instantly light up and turn it into a bigger screen or a second screen.

3. Many people, especially those who are engaged in design, PPT and code writing, need two screens, which means you should consider buying another desktop monitor besides one. Even if the desktop office takes up space, you don't like the cheap one, and it's expensive. The portable monitor occupies a very small desktop area, which is 15 inch, which fully meets the second screen demand for information search and comparison.

4. Go out and give a presentation to customers. This friend has been using a MacBook notebook before. Although Apple looks very high-end, it always feels awkward for two people to look at the notebook screen together, especially customers of the opposite sex. Sitting together always feels uncomfortable, which will make customers feel uncomfortable. This portable display can do it. You sit opposite the customer and use your notebook to operate. Customers can avoid the above embarrassment by looking at the portable display. Why not? It's an artifact.

5. The joint innovation 15Q 1F bought by a friend is still an organic light-emitting diode screen. Compared with many notebook screens with IPS panels, its color is more accurate. To put it simply, compared with IPS screen which needs backlight to display, OLED screen is self-luminous, which has the advantages of wide color gamut, high contrast and faster response speed. Simply put, the same wallpaper, the black part of the OLED screen will be darker. Joint Innovation 15Q 1F also has 8-bit +2-bit FRC dithering technology, 107 billion color display, 100% DCI-P3, and the color transition is smoother and more natural.

5. This joint innovation 15Q 1F also comes standard with 4096 active pressure-sensitive stylus. Those who like to draw can draw directly on the screen, but notebooks can't. You need to buy an extra drawing board.

Speaking of which, I suddenly feel that what my friend said is quite reasonable. At first, I was not very interested in portable display screens. After listening to it, I thought, hey, there are certain application scenarios. What he said really suits him. Although I won't face the customer directly, it's good to say that I can be a secondary screen. When I had the chance, I also tried one. I don't know what you think. Is there anyone like me who just thought this product was an IQ tax?
