Hey guys! I got some update for you from the world of VESA(Video Electronics Standards Association). They just did a workshop here in Tokyo this week mainly about DisplayPort and DisplayHDR. VESA’s compliance program manager, Jim Choate, divulge some important tidbits about what’s VESA is up to right now in the video arena. To quickly sum it all together, here are the six important pointers during the event.
- DP 1.4 — DisplayPort’s current specification is gaining traction. No wonder, since it specifies the features that’s highly appealing to video and panel developers out there. In particular, the Display Stream Compression (DSC), Forward Error Correction (FEC), the Multi-Stream Transport (MST), and the HB3. Official CTS is not yet released but early certification program for DP1.4 products is already being provided by Allion Test Labs. For more information on DisplayPort please visit DP website here.
- HB3 — As mentioned above about DP1.4 developers can now support higher link rates with the introduction of HB3. Well, that’s a complicated way of saying DisplayPort products can now support 8K videos. How they do that? For those who are more technically adept, please see VESA’s slide on HBR3 link rate support:
- DP 8K Cable Logo — So, with 8K capabilities, how can we move such data through the DP link? Many dubious DP cables have popped up claiming support 8K. To mitigate that issue in the market, VESA has created the first logo mark for DP cables that have passed stringent testing including testing their capability to support 8K. The idea of course is that consumers should buy DP cables with the the DP 8K logo. Familiarize yourself with the logo mark below:
- HDCP 2.2 — This is a side feature. DP has always supported HDCP (or High-Bandwidth Content Protection), even from the beginning. Now, generally there are two HDCP versions out there: 1.4 and 2.2. DP supports both. For products that support DP HDCP2.2, the HDCP feature must also be tested during the compliance testing. For more information about HDCP testing, please visit DCP LLC’s website.
- DisplayHDR — DisplayHDR is a new VESA specification for displays that support HDR. Particularly, this new VESA specification defines displays minimum requirements with regards to white luminance level and black level support. It also defines the bit depth performance for panels supporting DisplayHDR. Again, Allion is the only VESA ATC out there that provides compliance testing services for DisplayHDR. Please visit DisplayHDR’s new webpage for more information.
- USB Type-C — As you all know DisplayPort can run side-by-side with USB using the USB Type-C connector. In the handset world Type-C adoption is gaining traction mostly for its small form factor and support for power charging. With DP over USB-C, ultra high speed video support is another reason to adopt the USB Type-C connector.
After the DP Workshop, a two-day DP Plugfest was done at Allion Japan Inc. as they announced here. According to information we got, both events were successful in that many manufacturers and developers got valuable information on VESA’s direction with regards to DisplayPort and DisplayHDR, and also information on how to execute DP compliance tests at ATC’s like Allion for the new features mentioned above.
