ACTIVE ADAPTER CABLE CONNECTS A 4K MONITOR TO YOUR COMPUTER: This all-in-one video converter cable lets you transmit 4K video with digital audio from the HDMI port on your Blu-ray player, satellite/cable box, computer or media server to your 4K DisplayPort-enabled monitor, projector or television. It’s recommended for home theater systems, digital signage, trade show displays and conference room presentations. You can continue using your existing DisplayPort monitor without the expense of a new HDMI display to match your source device. TRANSMITS CRYSTAL-CLEAR TRUE 4K VIDEO WITH AUDIO AND 4:4:4 COLOR: HDMI to DisplayPort cable supports Ultra HD video resolutions up to 4096 x 2160 (4K x 2K) at 30 Hz with rich, full 7.1-channel surround sound, 36-bit Deep Color, HDCP 1.4 and 4:4:4 chroma subsampling for top-level PC gaming or using your HDTV as a PC monitor. Additionally, this cable transmits EDID information to ensure optimal display compatibility. PLUG AND PLAY CABLE: The plug-and-play cable requires no drivers or external power and is ready to use right from the package. The bus-powered cable receives any necessary extra power from the source device via the included USB-A connector. It is compatible with all HDMI sources and all major operating systems, including Windows, macOS and Linux. It is backward compatible with 1080p displays, so you can use the cable with older equipment.
