21寸显示器的基本特性

21寸显示器通常是指屏幕对角线长度为21英寸的显示器，这种尺寸的显示器既可以满足日常办公的需求，又可以支持游戏和电影观看等娱乐活动，以下是21寸显示器的一些基本特性：

- 分辨率：21寸显示器通常提供多种分辨率选项，包括1920x1080（全高清）和更高的4K UHD分辨率，分辨率越高，显示的画面越清晰。

- 屏幕比例：常见的屏幕比例有16:9（宽屏）和4:3（标准屏），宽屏显示器更适合看电影和玩游戏，而标准屏则更适合文档处理和网页浏览。

- 刷新率：刷新率指的是显示器每秒更新图像的次数，60Hz的刷新率已经足够应对日常使用，但如果你需要进行专业级的图形设计或视频编辑，那么高刷新率（如144Hz或240Hz）可能会更合适。
