Want to connect more HDMI devices than your TV has HDMI ports? In that case, an HDMI switch is the solution.

With an automatic HDMI switch from Marmitek, you can connect up to 5 devices to 1 HDMI input on your TV.

This way, there is only one HDMI cable to your TV. That looks tidy!  

How do you connect an HDMI switch? 

An HDMI switch is a small box with 2 or more HDMI inputs and 1 HDMI output. The HDMI cables from your HDMI equipment are plugged into the HDMI input, and the HDMI cable from your TV is connected to the HDMI output of the switch. This makes it easy to connect multiple HDMI sources to 1 TV and change the picture source.  

Our HDMI switches include a power adapter. The  Connect 310 UHD and Connect 350 UHD do not require an external power adapter.  


Do you have a 4K television? If so, you should use an HDMI switch that supports 4K signals. Otherwise, the resolution will remain limited to the maximum resolution of the HDMI switch.  

Our UHD 2.0 series is suitable for the latest Ultra HD 4K60 resolution (3840 x 2160/60Hz), High Dynamic Range (HDR), Deep Color and 4:4:4 chroma colours.

All of our switches also work with 1080p Full HD equipment.   

Matrix HDMI switch 

The Connect 642 Pro is an HDMI switch and HDMI splitter in one. This matrix HDMI allows you to connect 4 HDMI devices to 2 TVs. You can easily switch between both the connected HDMI devices and the TVs.    

Choose whether to display the content of the same device on both screens or if you both want to watch something different independently.  

A matrix switch is therefore ideal for use if, for example, you want to play games on a large screen one time and just watch TV the next. You do not have to keep changing cables and/or reconnecting equipment.   

With the remote control, you can easily switch between the HDMI devices you want to display and choose the screen to use.

Audio output & ARC

In addition to an HDMI output, the Connect 621 UHD 2.0 also has a digital audio output. This allows you to connect all connected HDMI sources to your AV receiver with just one cable. You determine the desired audio format (2.0 / 5.1 / 7.1) yourself.  

The audio quality of your flat screen TV often leaves much to be desired. Connecting a soundbar or an AV receiver is the perfect solution for better sound. You don’t want there to be a delay between the TV’s picture and the sound that accompanies it. Does your TV have an HDMI ARC connection? Then you can solve this problem easily.

ARC enables you to only have the sound from your TV to be sent back to the HDMI switch via the HDMI cable. Because the Connect 621 UHD 2.0 also supports ARC, you can connect your AV receiver or soundbar to the digital audio output on this HDMI switch with confidence. The TV’s picture will be exactly in sync with the sound. 

Do you watch Netflix, YouTube or interactive TV on your Smart TV?  With ARC, you can also reproduce this sound on your AV receiver or soundbar.

Operation out of sight 

Most HDMI switches in our range are equipped with an infrared receiver. This allows you to operate the switch when it is placed out of sight.

Automatic switching

Our switches switch automatically. You do not need a TV remote or an HDMI switch to switch to the desired HDMI source. This happens automatically. We do supply HDMI switches with remote control. However, these are only used when a connected HDMI source does not allow automatic switching.  The HDMI switches can also be switched manually if required.

No signal loss

All our HDMI switches have a built-in repeater and equaliser that prevent signal loss.  

Moreover, the Connect 621 UHD 2.0 & Connect 642 Pro are interference-free due to the solid metal interference-free quality housing.

HDMI splitters & HDMI adapters 

We also have a wide range of HDMI splitters and HDMI adapters. With an HDMI splitter you can, for example, connect your PlayStation to multiple displays with just one cable.

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.

HDCP 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.


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.

Future proof

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 is the best solution for connecting your HDMI devices and TVs.
