The Connect 621 UHD 2.0 enables you to connect up to 4 devices to your TV with one cable. This HDMI switch has an additional digital audio output that enables you to also connect your av receiver using a single cable, with the option to select your desired audio format (2.0/5.1/7.1). The included separate infrared receiver enables you to operate the switcher when it is positioned out of sight.

The UHD 2.0 range is suitable for connections with the very latest Ultra HD equipment, provided these are equipped with both HDMI 2.0 and HDCP 2.2 security.

HDMI 2.0
Compared to HDMI 1.4, the main improvement of HDMI 2.0 is its higher bandwidth (higher data rate), enabling 4K with higher frame rates and HDR.

The amount of data that can be sent is increased from 10.2 Gbps to 18 Gbps. This makes it possible to display 4K using a frame rate of 50-60 frames per second, 4:4:4 and HDR. HDMI 2.0 also offers support for a larger colour range (12-bit instead of 8-bit) and Dual View.

2.2 4K Ultra HD content is increasingly becoming the standard. Due to this development in digital video technology, the current copy protection, HDCP, has evolved into HDCP 2.2. To play the latest Ultra HD content (4K films or broadcasts) in the best possible image quality, all your AV equipment in the same chain must support this HDCP 2.2 security.

So, this does not only apply to the source and your TV. If, for example, you route your HDMI signal via an HDMI switch, splitter, AV receiver or soundbar, they must all be HDCP 2.2 compliant. If that is not the case, the material will not be displayed in the highest possible resolution (1080p instead of 4K) + the corresponding image quality OR will sometimes not be displayed at all.

Well prepared
Marmitek UHD 2.0 switch gear enables you to prevent these (future) problems and to make the most of your (existing) equipment. This range is HDMI 2.0/HDCP 2.2 compliant and therefore the best solution for connecting your HDMI devices and TVs.

“HDR stands for High Dynamic Range. HDR provides images with greatly enhanced brightness and higher contrast (brighter white and deeper black). Combined with better colour rendering, this creates a more realistic and natural image. In order to enjoy HDR, your TV does need to support the HDR feature. Material displayed in HDR quality (such as 4K Blu-ray, Netflix and YouTube) can then easily be played on your TV. HDR does not add more pixels, like 4K Ultra HD does, but enhances the pixels that are there.“

      Frequently asked questions

      What distinguishes this product from the Connect 620 UHD 2.0?

      The Connect 621 UHD 2.0 is equipped with a digital audio output to your receiver, ensuring perfectly synchronised image and sound through ARC.

      What can I do with the EDID switching option?

      • Infrared signals have a maximum reach of approximately 10 metres. Try a shorter distance.
      • Replace the battery in the remote control, it could be empty.

      No (or poor) image and sound

      If you experience poor or no image after connecting, try to recover the problem by connecting the devices one at the time to your screen (TV, monitor or projector). This way you can determine whether the problem lies with the HDMI sources, the HDMI cables, this product or the screen. HDMI devices which are not tested and certified by ATC (Authorized Test Centers) can cause image and sound problems.
      • Check if the power adapter is connected and plugged into the mains.
      • Only use High Speed HDMI certified cables for the best picture and sound quality.
      • Do not use HDMI cables that are longer than specified in the technical data.
      • Both the HDMI source and your screen have to support HDMI fully.
      • Check whether your HDMI sources, DVI device and screen support the copy protection HDCP (High-bandwidth Digital Content Protection).
