how to make my monitor display vertically

Resolution Resolution is a very important performance indicator. It refers to the number of points that can be displayed horizontally and vertically on the screen (lines and planes on the screen are composed of points). The higher the resolution, the more information can be included in the same screen. 480×800 resolution and 320×240 resolution are perfect display. Because there is little difference between the two, but the maximum resolution is not necessarily the most appropriate resolution. If 480×8000 LCD is used in 320×240 LCD, the display content will be smaller.   Visual area of LCD It refers to the part of the display area that can be used to display the image in practical application. The full size is actually the size of its frame and PCB board, and the part that can be used to display images does not reach this size at all, because the frame takes up some space. Generally speaking, the area of 4-inch 480×800 LCD is 51.84×86.4mm, and that of 3.5-inch 320×240 LCD is 70.08×52.56mm. But for LCD, the size of area is basically the size of the visible area, and the space occupied by the frame is relatively small. The 4-inch 480×800 LCD has a display area of 51.84 * 86.4mm.So choose LCD screen, choose suitable for your own equipment.   Reaction speed The unit of time used to measure reaction speed is millisecond (ms), which is the time required for a pixel to go from light to dark and from dark to light.

Pixel is a kind of unit. Generally speaking, it is invisible to the naked eye. How can we see the pixels of LCD? That is, if the image of LCD is magnified several times, many small square dots will be found. These small square dots are actually the so-called pixels.   The LCD splicing unit of LCD is a full-color screen, and red, green and blue are the primary colors of colors. Because LCD has many colors to realize, it needs to combine the red, green and blue lights to form pixels.   The pixel of LCD is a unit used to calculate the digital impression. Just like the photo taken, the digital impression also has continuous tone. If you enlarge the impression several times, you will find that these continuous colors are actually composed of many small dots near the color.   In addition, the pixels of LCD include real pixel display and virtual pixel display. The two technologies are different. The virtual display adopts virtual pixel technology, that is, LCD multiplexing technology. The same LCD light-emitting tube can be combined 4 times with adjacent LCD light-emitting tubes (down, down, left, and right combinations). Generally speaking, the pixel is a unit. The pixels of the current LCD display are 1920 * 1080, and the pixels of the Department display can be as high as 3840 * 2160. The higher the pixel, and more clearer the picture will be.

As an important carrier of indoor and outdoor advertising, LED display has a natural connection with advertising media. The survey found that in the past year, although the share of LED display in the outdoor application commercial market has shown a growth trend, the growth driver is not the increase in the number of screens, but the value-added of the original screens. According to the statistics of the authoritative research organization HIS, the global digital signage market revenue exceeded 15.1 billion U.S. dollars in 2018, an increase of 6% over the previous year. Among them, the digital signage display that occupies the largest share will achieve more than 6 billion U.S. dollars in revenue by 2021, creating a good development opportunity for the commercial display industry. This means that with the increase in application commercial market demand, the traditional business model is no longer able to promote the sustainable development of the industry. If the LED display industry wants to grow steadily, it must take a refined route and refine its applications. The development of the indoor application commercial market and the heavy investment in digital signage by display manufacturers are just a new attempt to this kind of change. LED advertising machine is also another mode for LED screen to penetrate into the field of digital signage The development of technology and the continuous improvement of market awareness have made the outdoor application of digital signage a trend, and the market scale has expanded rapidly.
