UnverifiedDP1.4带宽为32.4Gbps（有效25.92Gbps），可支持4K@120Hz或1440p@240Hz；DP2.0/2.1 UHBR20带宽达80Gbps，才能原生跑8K@60Hz或4K@240Hz无压缩78% similarUnverified标称支持4K的接收器需确认是4K@60Hz还是4K@30Hz，30Hz用于看视频尚可但拖动界面会明显卡顿，无线方案4K@60Hz对带宽要求极高，多数WiFi接收器实际只能稳定输出1080p78% similarUnverified支持4K@60Hz输出的投屏器实际带宽需求高，无线传输时若信号不足会自动降到1080P或降帧，标称4K不等于全程稳定4K，需看是否支持H.265压缩降低带宽压力77% similar
