这个4端口HDMI视频切换器可以让您与四个HDMI 2.0视频源共享一个HDMI 2.0显示器或投影仪。该切换器具有四个独立的视频输入，每个输入都可以支持60Hz的4K分辨率，使其成为连接四个视频源到一个具有有限数量HDMI 2.0端口的显示器的完美解决方案。

支持令人惊叹的Ultra HD 4K 60Hz画质

HDCP 2.2 HDMI切换器可以充分利用您的HDMI 2.0视频源的高动态范围（HDR）功能，并将其传输到您的UHD 4K 60显示器。与许多只支持30Hz刷新率的4K切换器不同，此切换器可在HDMI 2.0显示器上工作，输出分辨率高达3840 x 2160p，刷新率为60Hz。

不要被老技术的巧妙解释所迷惑。许多HDMI切换器支持4K但仅以30Hz刷新率工作，或者声称支持60Hz但会大大压缩信号以使其以更低的4:2:0色度子采样率工作。此4K 60Hz HDMI切换器使用最新的组件，为您的HDMI 2.0设备提供全面支持，支持真正的4K分辨率以60Hz与4:4:4色度子采样。支持HDMI 2.0设备意味着此切换器可以传输高达18Gbps的带宽，非常适合高分辨率的计算机任务。

该切换器向后兼容4K 30Hz和1080p显示器，这确保它可以与您的站点周围或数字标牌应用中的较低分辨率显示器（如电视或投影仪）一起使用。

无忧操作，自动切换

此切换器通过自动切换确保轻松操作，检测并选择新连接的设备。当打开像4K UHD蓝光播放器这样的4K媒体播放器时，它非常适用于自动切换到该设备。在您的教室或办公室会议室中，自动切换功能使得在同事之间轻松共享投影仪，促进即时协作。

HDMI切换器还支持手动操作，使用附带的红外遥控器或内置的前面板切换开关。

VS421HD20由2年StarTech.com保修，提供免费终身技术支持。
