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 More…

What's new about the HDMI 2.0 standard?

In HDMI 2.0, the biggest improvement was nearly doubling the bandwidth, allowing for up to 4K at 60hz video timing. Additionally, one of the new features was support for 4:2:0 sub-sampling.  This reduces the color information by 75% which reduces the overall data rate by 50%. In other words, support for 4:2:0 allows 4k 60Hz 4:2:0 to be transmitted within the same bandwidth as 4k at 30hz 4:4:4 or non-sub-sampled. On UltraRes, because we do have a very flexible and capable architecture, we were able to add support for 4K at 60Hz 4:2:0 with  a firmware upgrade that was made available to customers earlier this year. Other new features include Rec. 2020 More…
