Cable requirements
There are many different cables on the market, and not all of them will give you the best
experience with your monitor. Here are some specifications and certifications you should keep in
mind when purchasing a new cable for your monitor.
DisplayPort
DisplayPort is an audio/video interface that was first introduced in 2006 to provide a unified, easy
to produce replacement for the variety of monitor connectors that were in use at the time. Though
similar in capability to the more famous and TV-focused HDMI, DisplayPort has been designed with
a focus on computer monitors. Today, DisplayPort is the best way to connect Spectrum to your
desktop PC.
We recommend using a high-quality cable that is certified ‘DP8K’, has a DisplayPort connector on
either end, and is no longer than 3m.
to the DisplayPort
Certification:
Use a cable that is certified ‘DP8K’.
Connectors:
The cable can have a DisplayPort connector on both ends, or can
have a DisplayPort connector on the monitor side and a USB Type-
C connector on the computer side.
Speeds:
A cable that is certified ‘DP8K’ will provide support for all the
benefits of DisplayPort 1.4. It will enable Spectrum’s maximum
resolution, refresh rate, and color depth, and support all its
features.
Cables of higher certification, such as ‘DP40’ or ‘DP80’, will also
support all the benefits of DisplayPort 1.4.
A cable that is not VESA-certified may only offer support for
DisplayPort 1.2. It may not enable Spectrum’s maximum resolution,
refresh rate, and color depth, and it may not support features
such as Display Stream Compression (DSC) and High Dynamic
Range (HDR).
Spectrum can operate its ports in DisplayPort 1.2 mode, if your
computer supports DisplayPort 1.4 but you must use an uncertified
cable.
