Brand: Plugable. MPN: HDMI-SC3. USB-C DisplayPort Alternate Mode. The DisplayPort Alternate Mode is one of the more common modes currently available allowing an external display to be connected directly to the computer's internal graphics controller using the DisplayPort graphics standard. This has been adopted on some notebook systems with USB-C ports and especially those with Thunderbolt 3 ports. HDMI 2.0 compatibility. The Plugable HDMI Switch supports HDMI 2.0 output when using an HDMI 2.0 source and compatible cable. When utilizing HDMI 2.0's highest resolution and refresh rate (3840×2160@60Hz), twice the data is being transmitted as the maximum allowed by the previous HDMI 1.4 specification. Because of this, it's critical that an HDMI 2.0-compliant cable capable of providing the increased bandwidth be used for 4K@60 functionality. If using an HDMI 2.0 4K TV, it is strongly recommended to update the firmware/software of the TV for the best compatibility, performance, and stability.
