      Product Description

      The Plugable HDMI-SC3 3×1 HDMI Switch allows you to connect up to three inputs to one display and switch between the different sources at the touch of a button. Switch between computers, gaming consoles, and multimedia devices with HDMI or notebook computers with a USB-C or Thunderbolt 3 port capable of video output via “DisplayPort Alternate Mode” (more details below). Easily share a single monitor, projector, or television between multiple devices without swapping cables.

      Our HDMI switch requires no drivers and is compatible with Windows, Mac, Linux and Chrome OS. In most cases, no external power is required for the switch to function (but an optional USB cable for supplemental power is provided just in case). Supports HDMI 2.0 and 1.x compatible sources and displays, up to 4K 60Hz Y’CbCr 4:4:4 with 8 bits per color channel. The USB-C port accepts video input using the “DisplayPort over USB-C Alternate Mode” protocol, which can send a native DisplayPort video signal over a USB-C cable when using a supported USB-C cable and host system. The DP Alt Mode input converts this DisplayPort 1.2 signal to HDMI for output. Some USB-C and Thunderbolt 3 systems support this functionality while others do not. Plugable can help with USB-C compatibility questions prior to purchase.

      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.

      USB-C DisplayPort Alternate Mode

      Part of the USB-C 3.1 specification optionally allows the USB-C port to carry non-USB signals in Alternate Modes. 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. Because Alt Mode video output over USB-C must be built-in by your laptop, tablet, or phone manufacturer, it’s always good to good to confirm if your device supports this feature prior to purchase.

      Some examples of supported systems include: MacBook Pro 2016 and later, iMac Pro, iMac 2017 and later, Mac mini 2018 and MacBook Air 2018. The USB-C charging cable that comes with many Apple systems does not support video transfer and a fully featured USB-C or Thunderbolt 3 cable should be used instead. Dell XPS systems including; XPS 9350 and later, XPS 9550 and later. Many systems from other manufacturers with USB-C or Thunderbolt will also work with this switch. If you are unsure if your system supports USB-C or Thunderbolt 3 display output please email our support team at with your computer manufacturer name and model number and we are happy to help!

      Unsupported USB-C implementations include ASMedia based USB-C controllers, PCIe add-in cards with USB-C, and many gaming notebooks with discrete graphics cards will not support DispayPort Alternate Mode.

      Not recommended for use with phones and tablets including Samsung S8, Note8, Galaxy Tab.


      Q: Do I need to use the provided USB Micro-B cable to provide power to the switch?
      In most cases, the source device(s) will provide sufficient power for the switch to operate. If the LEDs on the switch do not illuminate or the device is not behaving as expected, it may be an indication that the source device is not providing sufficient power, which can be resolved by using the included USB cable for supplemental power.

      Q: I am only getting 4K@30Hz when using your switch. How can I get 4K@60Hz?
      There are several different reasons why a 4K display would be limited to 4K@30Hz using our switch. We would recommend first checking:

      • System specifications to ensure that the internal graphics processor can support 4K@60Hz and that the output port on the system/GPU can support 4K@60Hz.
        The HDMI output port must be HDMI 2.0 compliant.
      • Display specifications to ensure that it can support 4K@60Hz from the desired input port. HDMI input ports must be HDMI 2.0 specification.
        Ensure that the HDMI cable is HDMI 2.0 (High Speed) compliant.

      If both the system’s GPU, HDMI or USB-C output port and the display support 4K@60Hz, please check the Windows Advanced Display Adapter settings to ensure that 60Hz is available and selected from the drop-down list.

      If 60Hz is not listed and you are connected to our switch with an HDMI High Speed cable or compatible USB-C cable, please double-check that the display has HDMI 2.0 ports. Additionally, some 4K TVs and monitors must enable an “HDMI 2.0″, “HDMI UHD Color”, or “Ultra HD/UHD Deep Color” (or similar) setting for 4K@60Hz to work via HDMI. Please consult the display’s manual and check the display’s menu settings to see if there is an applicable setting.

      Q: Does the Plugable HDMI Switch support 4:4:4 color/chroma sampling?
      Yes! Our adapter supports Y’CbCr 4:4:4 and RGB 4:4:4 chroma sampling at 4K@60Hz resolutions at 8bit color depth (8bpc). Please be aware that the display that is being connected must also support 4:4:4 color depth and the HDMI cable must be HDMI 2.0 capable while connected to an HDMI 2.0 input port on the display.

      Q: If I use an HDMI 1.4 source device, will the switch upscale the output to HDMI 2.0?
      The switch is not an upscaler; it will output video at the same resolution it receives from the input device.

      Q: Does your HDMI Switch support HDR?
      Our Plugable HDMI Switch does not support HDR imaging (High Dynamic Range). HDMI 2.0a is the minimum specification for supporting HDR, our adapter supports HDMI standards up to version 2.0.

      Q: Will the USB-C charging cable that came with my MacBook Pro or 12” Retina support Alt Mode video over USB-C?
      No. Unfortunately virtually all USB-C cables provided as charging cables do not support Alt Mode video.

      Q: Where can I get a USB-C to USB-C cable that supports video to connect my system to the switch?
      Our Plugable USB 3.1 Gen 2 Type-C USB-IF Certified 3ft (1 meter) cable can be used to connect your system to the USB-C input port on the HDMI Switch.

      Q: The Plugable HDMI Switch does not work with my MacBook system using the USB-C cable that came with my computer?
      Unfortunately Apple included a USB-C cable that only supports USB 2.0 and charging with the Apple USB-C power supply, a separate cable is necessary for video transfer to the USB-C port on the Plugable HDMI Switch. Our USB 3.1 Gen2 Type C USB-IF Certified USB-C to USB-C Cable can be used instead of the Apple cable.
