A good computer monitor is not only a good tool for office, but also a good assistant for gaming. In the face of many brands and complex performance parameters of display products, how should everyone choose? Computer monitors are compared and tested together→
A total of 20 computer monitors were purchased in this comparative test, all with a screen size of 27 inches, and the unit price ranged from 1199 to 3299 yuan, of which 10 samples were declared suitable for gaming/e-sports scenarios in the page introduction.
The test was entrusted to Shanghai Institute of Quality Supervision and Inspection Technology, and the performance of the display was tested from four aspects: display clarity, display responsiveness, energy saving, and visual health.
Display sharpness: The resolution of 20 samples reached the declared value, and the color gamut coverage of 1 sample did not reach the declared value of the page.
Clarity is the most concerned content of consumers when choosing a monitor, many consumers reflect that the monitor they bought is not clear and the display is distorted, how is the test situation?
In addition to the resolution, this sharpness test also tested color consistency, color gamut coverage, and grayscale levels to comprehensively evaluate the clarity of the display.
The results show that the relevant indicators of 20 samples meet the standard requirements, among which the resolution is above 1080p high-definition level, the measured values all reach the page declared value, and only 1 sample has the color gamut coverage does not reach the page declared value.
Overall, the following 6 monitors excel in terms of display clarity.
Samples with excellent clarity performance on 4K displays
Samples with excellent clarity performance on 2K displays
Display responsiveness: Claims that the sample refresh rate and response time of the gaming monitor are better than the overall level
The refresh rate and response time have a significant impact on how fast the display renders after receiving the signal. The test found that the refresh rate and response time of 10 models of gaming monitors were better than the overall level, and the measured refresh rate was 144Hz and above, and 8 of them had a response time of less than 5ms.

According to the test and value of GB/T18910.61-2021, it was found that the response time of 8 of the 20 samples did not reach its declared value, in this regard, most companies said that they would rectify the page claims, and at the same time promote the correspondence between enterprise standards and national standards.
Overall, the following four monitors excel in display responsiveness.
Samples with excellent responsivity are displayed
Energy saving: Some samples have high power in the sleep state
In addition to high performance, low energy consumption is also being paid attention to by more and more consumers. Experimental findings. In the standard test environment, the energy efficiency and sleep/shutdown power of 20 samples met the relevant standard requirements.
At the same time, the test also simulated the actual usage habits of consumers for testing, that is, when the external connection of the display is normal and the equipment automatically enters the sleep state with the sleep of the computer host, it is found that the sleep state power of some samples is higher, and the laboratory state is quite different, such as the sleep state power of one sample reaches 10.14W, which is equivalent to more than 2 times the standby power of the air conditioner (usually the standby power of the air conditioner is 1W-5W).
Overall, the following four monitors excel in terms of energy saving.
Samples with excellent energy saving performance
Visual health: The anti-blue light effect of software is generally very weak
The test found that the display usually has hardware (physical) and software two blue light protection methods, this time 20 samples have hardware blue light protection and the protection effect is better, the measured screen blue light spoke brightness (unit: W·m-2·sr-1) between 0.37-1.08, far lower than the relevant standard limit (<100).

At the same time, 18 of the 20 samples also support the software anti-blue light function, but after opening, it is found that the actual effect is generally very weak (maximum reduction of 0.74), and individual samples will have a greater impact on color temperature, brightness, color aberration, etc., which will make consumers obviously feel the color cast of the screen.
Example: Anti-blue light on the effect of color (cyan, magenta)

Concentrate:
1. The comparative test results are only responsible for the sample, and do not represent the quality status of different batches and different models of products of the same brand;
2. No enterprise or unit shall use the results of this comparative test as commercial publicity;
3.1 ★ represents 1 point, 1 ☆ represents 0.5 points, the maximum is 5 points, the more points, the better the sample performs in this test;
4. Underscored indicates that it does not reach its declared value, dropping 1 star, and the number of stars after the falling star is shown in the table.
Consumption tips
(1) Purchase
1. Choose the monitor size according to your personal needs. The right monitor size is generally one where the eye can see the entire screen without much movement.
2. The monitor, computer graphics card, and connection port (cable) version should be corresponding. When choosing a monitor with a high refresh rate, it is recommended to determine whether the equipped computer graphics card configuration supports it, and it is recommended to use the original data cable.
The actual refresh rate of the display follows the barrel short board effect
3. Rationally view the merchant's publicity about 1ms response time. When you have high requirements for display performance, consider choosing a monitor with a short response time. In addition, you can focus on referring to panel types, such as VA screen, Nano-IPS, Fast-IPS, etc.
(2) Use
1. Adjust brightness with the environment. During daily use, the brightness of the display can be kept at about 50%, and the environment should be adjusted appropriately when the environment is slightly dark or slightly bright, and the display should not be used in too bright or too dark environment.
2. Turn off the power in time. The display also consumes energy in the sleep state, when it is not in use, the power of the display should be turned off, and the power cord and signal cable should be unplugged for a long time without using it for a long time.
3. Look down at the screen at a 15-degree angle. For daily use, it is recommended to keep the distance between the eyes and the screen above 50 cm, and it is best to use a downward viewing angle of 10-15 degrees, that is, the eyes are slightly downward to look at the screen.
