当前，2K显示器在生活办公、摄影设计制图、电竞等领域应用广泛，尤其是专业级2K显示器更是深受"极客"人群的青睐。对于主流大众来说，高性价比无疑是最重要的考量标准，而AOC 刀锋5S Q2781PQ显示器一经推出即刻成为众多消费者认可、热捧的机型之一;而对于摄影爱好者和设计师来说，一台高分辨率的显示器可以提供更高清更精准的色彩表现，还原真实。卢瓦尔专业制图显示器LV323HQPX不仅拥有高分辨率同时还拥有多项色彩还原技术，兼具护眼功能及人体工学设计，让制图更加事半功倍;另一个显示器品牌深耕电竞领域，带领专业及业余玩家进入更高层次的游戏体验， 2K显示器的普及，将带来一场视觉的革命，也会有更多视讯厂商加入其中改变传统的观念，令显示设备更加有趣。
2K显示器是指具备2K分辨率的显示器设备。与目前最主流的清晰度标准1080P分辨率不同，2K显示器具备更突出的画面还原能力与画面质感，能展现更接近原画级别的高质量画面，提供高质量视觉体验。未来，2K将逐步取代1080P成为下一代最主流的清晰度标准。显示分辨率(屏幕分辨率)是屏幕图像的精密度，是指显示器所能显示的像素有多少。由于屏幕上的点、线和面都是由像素组成的，显示器可显示的像素越多，画面就越精细，同样的屏幕区域内能显示的信息也越多，所以分辨率是个非常重要的性能指标。 而2K分辨率是指屏幕分辨率等级，具体到数值上体现为屏幕横向像素达到2000以上。
主流2K分辨率为2560x1440，目前国内数字影院放映机主要采用这种分辨率。同时，2K分辨率还有多种类别，如2048×1536(QXGA)、2560×1600(WQXGA)、2560×1440(Quad HD)等，也被视为2K的一种。2K分辨率的画面显示能精准到每一个像素点，足够清晰细腻，呈现的高清画面通透自然，视觉效果极佳，同时点距又不像4K太过精细，视觉上令人难受且成本较高。2K显示器对于专业摄影设计制图、电竞玩家等尤其重要，能够保证画面细腻度及色彩还原度，让作品效果更佳，让游戏体验更燃。除此之外，2K屏还能加载更多的内容，实现一屏多用，提升工作效率。27英寸的显示器配置1080P的分辨率，的确就显得有些粗糙了。尤其是习惯了手机那种细腻的画面之后，再看27英寸1080P的画面，的确有一种曾经沧海难为水的感觉。现在，就有不少厂商给27英寸的显示器配置4K的分辨率，但是这又有点矫枉过正。
4K的分辨率显示器价格偏贵，而来4K分辨率的显示体验效果也不好，软硬都需要优化。随着显卡技术和液晶面板生产技术的发展，27英寸乃至32英寸液晶显示器开始成为2K显示器的市场主流，分辨率更是达到了标准2560×1440的水平。而且，为适应2K分辨率下的音像高速输出，高清多媒体接口HDMI正成为2K显示器标配，此外，诸如AOC、爱攻、卢瓦尔等视讯领导品牌还推出了支持专业设备输出/输入接口--DP接口的2K显示器，更是能实现对周边设备最大程度的整合，实现与电视盒、音响、PS3、PS4、Xbox等影音游戏设备以及智能手机、数字相机、摄像机等摄影移动设备的连接。
