DP 1.4

DP 1.4 means DisplayPort version 1.4, a video and audio connection standard. It identifies the interface generation, but does not by itself guarantee a specific resolution, refresh rate, or feature set.

What DP 1.4 means

DP 1.4 is short for DisplayPort 1.4, a version of the DisplayPort connection standard used to carry video and audio between compatible devices. On a display product page, the label usually identifies the version supported by a DisplayPort input or output.

The version can indicate support for a newer DisplayPort feature set than earlier versions. However, the label alone does not specify the exact modes a particular display accepts or provides.

Why it matters on DockFit

DP 1.4 may be relevant when you are matching a monitor with a desktop computer, laptop dock, graphics card, or other source. It can help you compare interface generations, but it is only one part of checking whether a display will work for your intended setup.

The actual result can depend on the source device, cable, port type, display settings, and the monitor's published input limits. A DP 1.4 label is therefore a capability indicator, not a quality rating or a promise of better picture quality.

What the label does not tell you

“DP 1.4” does not, by itself, tell you:

The maximum supported resolution and refresh-rate combination
Whether Display Stream Compression (DSC) is supported
Whether multi-stream transport or daisy-chaining is available
Whether HDR works through that port
Whether the port is an input, an output, or both
Whether the included cable supports the intended connection
Whether a connected laptop, dock, or graphics source can provide the desired signal

It also does not prove that every feature associated with the DisplayPort 1.4 standard is implemented on the product. Check the product's own specifications for the details that matter to your setup.

What to check on a product page

Look for the full port description rather than relying on the version label alone. Confirm the number and role of the DisplayPort connectors, the supported resolution and refresh-rate combinations, and any stated requirements for HDR, DSC, or daisy-chaining.

If the listing only says “DP 1.4” without these details, those capabilities remain unknown. You should also check the specifications of the connected source and the cable, since the complete connection is limited by the relevant devices and accessories.
