With the proliferation of display capabilities, the price of many new flagship displays has skyrocketed to tens of thousands of people. This is a situation that people can't expect. Faced with this situation, we recently discovered that many users choose to use TVs as monitors. To use, it may be misleading to some users, today we come to talk about 'TV can be used as a monitor?' This topic.
Why do users choose TV as monitor?
First, the working principle and imaging mode of liquid crystal displays and LCD TVs are basically the same, the functions of the two are highly coincident, and the same is used for screen output. The internal structure design and the backlight source are not much different. However, compared to displays, LCD TVs have the outstanding advantages of cost performance, and the size of specifications than monitors.

Second, there are some manufacturers that offer dual-use products for TVs and monitors. Some people share the use of TVs as display installation techniques. In addition, current LCD TV data interfaces generally have VGA and HDMI, and no computer technology is connected to the host computer. You can easily connect the TV to the host.
Third, monitors and televisions are also used as screen output devices. With the development of technology, there are many similarities in terms of appearance and function. Even in many cases, the similarity of some products makes it difficult for consumers to have a high degree of similarity. Distinguish between TV and monitor.
Since TV can be used as a monitor, according to conventional thinking, TV should tilt the display market, but in fact it is not. This is mainly because there is a big difference between professional use and product positioning. Here we will Let's talk about where the technical barriers between the two cannot be achieved.
TV when the monitor really shines!
First of all, compared with monitors, the brightness of TV is too high. At present, the brightness of mainstream displays is 200-300cd/m2. By adjusting the brightness, the optimal brightness range of 120-150cd/m2 can be reached, and the general brightness of TVs will reach 400- 700cd/m2, is very harmful to eyes when used at close range. It's no surprise that it is 'bright blinking'! At present, TVs in the home are all over 40 inches. Use such a big TV to work at close distances. Want to know.
After connecting the host to the TV, the display is blurred, unstable, and the color cast is serious.
In addition, the most intuitive experience of using a TV to connect to a host computer is that the display screen is blurred, unstable, and the color cast phenomenon and the near-distance viewing of the image detail loss are serious. This indirectly reflects the loss of the gray-scale output of the TV. Take 256 gray scales as an example. , The TV will show 16-236, and the rest of the gray level will be lost.
Second, although 4K TVs are already very rich, at the same resolution, the size of TVs is much larger than that of monitors, and the distance between display screens is relatively large. You can see a noticeable graininess with the naked eye. The screen is very rough. The user with high pursuit of effect must be unbearable.
The biggest difference between monitors and televisions is their professionalism.
Of course, the same as a display device, the biggest difference between the display and the television is the professionalism. For the display, we pursue a rich color and precise reduction. We hope that the display can achieve WYSIWYG and the TV as a home entertainment device. , Colorful colors, in order to please the user's eye.
If you try to connect the host computer to the LCD TV, you will find that the output screen on the LCD TV has become too bright, and the color cast of some models has reached an appreciable level, with serious color casts. The root cause lies in the gamma adjustment. The default gamma value of the monitor is 2.2. Due to different application scenarios, the gamma value of the TV is around 2.4. In this case, the TV is difficult to be used as a monitor by the user, and the television is used. It's okay to watch the video, if it's browsing the web or office.
In addition, compared with televisions and monitors, the refresh rate is generally 30-60Hz, which can not reach the 144Hz of the current gaming monitor. There is a serious smear phenomenon in the game playing, compared with the display screen of the monitor, the effect of the TV connection host display. Touching.
TV when the monitor is really bad!
There is specialization in the industry, and existence is reasonable. Although the current television can be connected to the host to achieve the role of the display, and since the television is equipped with interfaces that can be connected to the host, it has been nearly 20 years, and the display can still develop rapidly so far. Instead of being replaced by television, some functions of the monitor are really irreplaceable, especially in terms of professionalism.
The professionalism of the display is reflected in its careful classification of different groups of people, the design of graphic displays, and e-sports displays.... These displays have functions that cannot be replaced by televisions. After all, televisions have always been more In favor of home entertainment.
If the user is merely watching a video on the TV for computer output signals, playing the game occasionally is only a 'display' function. If it is used to browse the web, work or even process pictures, the effect will be much less. In addition, the color of the TV can not meet the user's needs. In addition, TV as a product focused on dynamic display, for the static screen display much worse.
All in all, if you do not want to “brightly blink”, you still have to choose the monitor that best suits your needs, instead of just listening to the truth, using a TV as a monitor.
