DisplayPort 2.0 - Just the Facts

August 22, 2019 at 8:00 AM

 

HDMI might be the most popular connection standard for TVs and monitors, but DisplayPort comes in a close second place. This high quality alternative is similar to HDMI in many ways including smaller connectors, digital video, audio/video on one cable, high definition video, 3D capabilities, etc. It has most of the same features of HDMI, plus some capabilities that are important for the high-graphic demands of business applications. And now, DisplayPort is getting an upgrade to DisplayPort 2.0! Let’s look at the facts.

 

DisplayPort 2.0 is slated to launch next year with products incorporating the technology hitting the market in late 2020. This new iteration takes the connection standard into the next generation with triple the bandwidth compared to DisplayPort 1.4a. DisplayPort 2.0 will deliver faster refresh rates and be able to single stream higher resolution formats like 10K and 16K at 60Hz at up to 30 bits per pixel with HDR. For smaller formats, it will also be capable of multiple displays at higher resolutions including two 8K at 120 Hz with 30 bpp and HDR, or two 4K displays at 144 Hz at 24 bpp with no compression.

 

In addition to bandwidth and high-resolution upgrades, DisplayPort 2.0 has some other improvements including Panel Replay which reduces power requirements while enhancing how a display is refreshed. Display Stream Compression (DSC) will be standard and allows for extremely high refresh rates and high-resolution. Plus, a multi-stream transport feature will make for easier daisy chain displays.

 

When it comes to the connectors, DisplayPort 2.0 will be backwards compatible with previous versions. It can be used in “DP Alt Mode” using specific USB-C connectors, allowing for one cable to provide high-speed video & data with optimal performance. The physical interface layer of Thunderbolt 3 is also utilized in this new standard, which will be especially appealing with a merger between Thunderbolt 3 & USB 4 in the works.

 

When it comes to connectivity, HDMI might be the most widely recognized medium, but DisplayPort 2.0 is coming in hot with lots of features that make it a very attractive option. And luckily, L-com has a full line of DisplayPort cables for all of your needs.

 

All About USB 3.2

January 10, 2019 at 8:00 AM

 

We’ve discussed the difference between USB 3.1 Gen 1 vs. Gen 2, but now comes the next level for Universal Serial Bus - USB 3.2. What makes this newest USB standard stand out? First and foremost are increased bandwidth and USB Type-C connector and cable support. Here, we’ll take a look at all the specs, so you’ll know all about USB 3.2.

 

While USB 3.1 Gen 1 brought 5 Gbps and Gen 2 doubled that to 10 Gbps speeds, USB 3.2 then doubles down again to offer 20 Gbps speeds – the most notable feature of the new standard. The way it provides those speeds is a little different though. USB 3.2 utilizes what is being called multi-lane operation, where devices use two lanes of 5 Gbps or 10 Gbps running together to transfer data at the same time over extra wires inside the USB cables. This allows for a cumulative data transfer rate of 10 Gbps to 20 Gbps.

 

What does this new standard mean for older USB cables? Fortunately, the new standard will be backward compatible with older standards. Even more fortunately, if the host and recipient devices are USB 3.2 compatible, older USB cables will also see a boost in speeds as great as 2 Gbps. USB 3.2 will also support USB-C connectors and their features such as power delivery, alternate modes, and digital audio, video and data on the same cable.

 

Overall, the new USB 3.2 standard is a big upgrade in terms of speed, but otherwise, it’s not a huge shift – which might be good news for those not ready to replace all of their older USB equipment. Though faster speeds are always good news, so this update is sure to be a welcomed change.
