i3CONNECT can only take responsibility for the correct functioning with the cables supplied with the deliveries.
Power cable lengths
Generally speaking there is no maximum cable length for power cables, as long as the local electrical regulations are being followed. As the voltage level in AC power cables can be dangerous, it is important to follow local safety requirements as well as exercise care when handling & repairing power cables.
Network cable lengths
Network cables come in a variety of types and quality levels. Maximum cable lengths of the manufacturer need to be respected. However signal (and hence communication) quality in practice highly dependence on the quality of the connectors (and how the connections are being made) as well as the interconnectivity.
Furthermore network design and network switching gear (routers, switches, hubs, …) actively contribute to robust communication between devices. We strongly suggests to use industry best practices with our displays.
HDMI for long distance video
HDMI cables are used for video and audio transfers from source to destination. HDMI cables of decent quality are quite robust for communication. Cables from reputable suppliers allow to transfer 4K display information at 60Hz with audio over 5 meters and more.
No touch over HDMI, without Touch Out USB
However, touch control and interactive display peripheral control cannot be used with HDMI alone. For this it is recommended to also attach a Touch Out USB cable between the laptop and the interactive display. This Touch Out port needs to be the matching one for the HDMI port e.g. HDMI 2 uses Touch Out 2.
Avoid extending solutions
In order to preserve the quality of the video & audio transfer it is suggested to avoid, or minimise the use of patch panels, daisy-chained cables or other extender solutions. If these connections or pass-throughs cannot be avoided, it is critical that components of high-quality are being used and installation is done with great care for detail and connectivity. Bad connections in table plates or wall plates account for the majority of video and audio quality issues, even for shorter distances.
USB cables for short distance video
USB data communication is used for different data types. User input data (keyboard, mouse, touchscreen), local file transfers and video & audio devices (e.g. for video conference cameras) have all become popular users of USB, with increasing resolution and refresh rates and hence increased bandwidths.
USB 3.2 and lower for older peripherals
For one of the latest USB versions, 3.2 Gen2 x2, the maximum cable length is 3 meters to guarantee performance at high data rates. This is also the length of the cable supplied with the displays.
USB-C (Type C) for video and touch transfer
Recently, laptop monitor video & touch control can be transferred to the display over USB-C if it has the DP (DisplayPort) protocol. USB 3 and lower does not support these features.
Not all laptops and cables supporting USB-C have DisplayPort. Without this, video transfer will not occur. Be sure to choose a correct cable.
The Type-C cables supplied with the i3CONNECT displays have been tested and qualified to provide maximum interoperability with 3rd party systems and devices.
Beyond these lengths, choose HDMI or wireless
It is possible though that a cable with a greater length than recommended below will work with some combinations on our displays. However, as there are a lot of factors involved in the interoperability, a minor change (different source computer, different cable, production variation) can cause the combination to become non-functional. Then it will work or it will not work; there is little to none graceful degradation.
If display content is to be shared over longer distances, we suggest using HDMI cables or a digital screen sharing product like i3CONNECT Studio
