What parameters should be considered when choosing a liquid crystal display?

When choosing a LCD monitor, the main considerations are the resolution, panel type, and refresh rate, which are the three core parameters. Additionally, details such as brightness, contrast, and interfaces should be matched with the specific usage scenario.

I. Core Parameters: Key to Display Experience

These three parameters directly affect the clarity of the picture, color reproduction, and smoothness. They are the primary factors to consider when making a selection.Resolution: Determines the clarity of the picture
The higher the resolution, the more pixels are displayed on the screen, resulting in a more detailed picture.
Main choices: For screens larger than 27 inches, 2K (2560×1440) is recommended. For screens 24 inches or smaller, 1080P (1920×1080) is sufficient. For those seeking ultimate clarity, 4K is an option.
Panel Type: Determines color and response speed
IPS panel: Accurate colors, wide viewing angles, suitable for design, office, and film viewing, but with relatively slower response speed.
TN panel: Fast response speed (usually 1ms), low price, suitable for gaming, but with poor color and viewing angles.
VA panel: Balances contrast (the picture appears more pure) and color, with a response speed between the two, suitable for comprehensive use.
Refresh Rate: Determines the smoothness of the picture
The higher the refresh rate, the more frames are displayed per second, resulting in smoother dynamic pictures without ghosting.
For ordinary office / film viewing: 60Hz is sufficient; for gaming players, a refresh rate of 144Hz or above (requiring a high-performance graphics card) is recommended.

II. Secondary Parameters: Optimizing the User Experience

After meeting the requirements of the core parameters, focus on the following details based on the usage scenario.
Brightness and contrast: The recommended brightness is ≥ 300cd/㎡ to ensure clear pictures in bright environments; the higher the contrast, the richer the gradation of light and dark (VA panels usually have a higher contrast).
Response Time: The time it takes for pixels to switch colors, measured in ms. For gaming, 1ms is preferred, and for daily use, 5ms or less is sufficient.
Interface: At least one HDMI 2.0 or DP 1.2 interface is required to support 2K+144Hz output; if connecting a laptop or mobile phone, pay attention to whether there is a Type-C interface (supporting reverse charging is better).
Eyes-protecting Function: Prioritize models with low blue light certification and anti-glare features to reduce eye fatigue during long-term use.

III. Select by Scenario: Precisely Matching Requirements
Different usage scenarios have different priorities for parameters. You can directly target specific scenarios.
