Evaluating the quality of a computer display screen can start from multiple aspects, including resolution, color performance, brightness and contrast, viewing angle, response time, refresh rate, durability, and design. Here are some specific evaluation methods:
1. Resolution: Resolution is the number of pixels that a screen can display, usually expressed as "horizontal pixels x vertical pixels". High resolution means that the screen can display finer and clearer images. For most purposes, such as daily office work, web browsing, and watching high-definition videos, Full HD (1920x1080) or higher resolution is sufficient. For professional design or gaming, a 4K (3840x2160) or higher resolution monitor may be required.
2. Color expression: Color accuracy is crucial for professional fields such as design, photography, and video editing. IPS and VA panels typically have a wider color gamut and more accurate color representation than TN panels. Some high-end displays also support wide color gamut standards such as Adobe RGB and DCI-P3.
3. Brightness and Contrast: High brightness can keep the screen clear and visible in bright environments, while high contrast helps enhance the depth and depth of the image. Note that excessive brightness may cause discomfort to the eyes, so it needs to be adjusted according to the usage environment.
4. Perspective: IPS and VA panels typically have a wider perspective, which means there is less color and brightness attenuation when viewed from the side of the screen. The viewing angle of TN panels is relatively narrow.
5. Response time: Response time refers to the time required for the screen to switch from one color to another. A shorter response time can reduce ghosting in games and dynamic images. For gamers, this is a very important indicator.
6. Refresh rate: Refresh rate refers to the number of times a screen updates its image per second, usually measured in hertz (Hz). A high refresh rate (such as 144Hz or higher) can reduce motion blur, making games and dynamic images smoother.
7. Durability and design: Consider the material, heat dissipation performance, base stability, and whether there are anti glare, eye protection, and other characteristics of the display. The appearance design is also an important factor that cannot be ignored, as it relates to the coordination between the monitor and the surrounding environment, as well as the comfort of use.
8. Actual testing: Before purchasing, it is best to personally visit the physical store or compare the actual performance of different monitors through online review videos if possible. Pay attention to observing the performance of color, brightness, contrast, viewing angle, etc., and try to conduct some fast moving or high dynamic range image tests to evaluate response time and refresh rate.
Evaluating the quality of a computer display screen requires considering multiple aspects and selecting the appropriate monitor based on one's actual needs and budget.
