DisplayPort 1.3 vs HDMI 2.0

We recently caught up with Marques Girardelli, Planar’s electrical systems manager in the R&D organization and Becky Connors, product manager for large format displays, to ask about the emerging connectivity standards around DisplayPort and HDMI.  This is the third post in a series covering these connectivity topics.

How does DisplayPort 1.3 compare with HDMI 2.0 in terms of performance?

When comparing DisplayPort 1.3 with HDMI 2.0, DisplayPort 1.3 has several key advantages. First, the video bandwidth of DisplayPort 1.3 is much higher than HDMI 2.0.  This means that DisplayPort 1.3 can support higher resolution timing such as 8K at 60Hz, where as HDMI 2.0 can support 4K at 60Hz max. Second, DisplayPort 1.3 has the ability to transmit multiple video streams on one cable through the MST feature allowing multiple monitors to be daisy-chained together (although there are limitations as to the number of displays and resolution supported, which makes it more appropriate for desktop uses than video walls).  Finally DisplayPort includes installer-friendly locking connectors. HDMI doesn’t natively support locking connectors though many Planar products do provide support for threaded hex nuts for special-locking HDMI connector which installers can find in specialty stores or through distribution.

HDMI 2.0 does have two main advantages over DisplayPort 1.3. First, the max cable lengths achievable on HDMI are much higher than DisplayPort. Distances of 30 meters with 1080p are not uncommon with Planar displays. We’ve seen it work with 40 meters at lower resolution. For 4K on our Planar UltraRes products, we’ve regularly been able to get about 10 meters. On DisplayPort, the standard lists 3 meters maximum. Now, longer distances are possible depending on resolution and bit depth, but only up to about maybe 15 meters or so max at a lower resolution and only with a very high quality source and display. And then finally, HDMI has a much higher install base. Nearly every consumer source out there and displays both contain HDMI. Your set top boxes, your Blu-Ray players, your TVs, smart phones and tablets - everything has HDMI. Whereas DisplayPort is mainly confined to PCs and some desktop monitors and a few larger format displays today, but is growing in importance as a standard in the industry for connectivity.

You can see the two standards compared in the table below:




Max Resolution

4K @ 30Hz (HDMI 1.4a)

4K @ 60Hz (HDMI 2.0)

4K @ 60Hz (DP 1.2)
8K @ 30Hz (DP 1.3 4:4:4)
8K @ 60Hz (DP 1.3 4:2:0)

Which products in Planar’s line-up support DisplayPort and HDMI?

DisplayPort 1.3 and HDMI 2.0 will be fully backwards compatible with earlier versions which means you can use a source with a HDMI 2.0 output on displays with HDMI 1.x inputs or DisplayPort 1.3 output on a display using DisplayPort 1.2 standards.  Like all connectivity standards,  version numbers don’t necessarily reflect the feature set of the products.  See specifications and product manuals for each individual model for details on which features the display will support. 

Planar’s large flats with either HDMI and/or DisplayPort connections include:

DisplayPort is also the interface on the Planar® Mosaic™ architectural video wall product line and is available on Planar’s Clarity® Matrix LCD video wall system, along with HDMI.  You can also find DisplayPort and/or HDMI on a wide number of desktop and touch monitor products from Planar, including the new IX-Series monitor, Planar IX2850, with 4K resolution.
