Compared to video transmission without compression, DSC saves power and can allows for resolutions up to 16K (15360 x 8460). This "light compression" allows video to be encoded and decoded in real time with very low latency, making it ideal for high performance applications like gaming. Display Stream Compression (DSC) is a new standard first introduced in DisplayPort 1.4 that enables visually lossless compression of 2:1 or 3:1. The only way to transmit more bits is to add more lanes to the cable or compress the signal. High resolutions of 8K and beyond, greater color depths and increasing frame rates push the limits of video cables, even high bandwidth cables like DisplayPort. What is Display Stream Compression (DSC)? As version 1.4 cables were only TESTED to meet 10.2Gbps, it is possible that certion v1.4 cables. Depending on the resolution, active cables can easily reach 150-ft or more. Support at 60Hz requires that the cable meet or exceed 18Gbps. They regenerate or increase the strength of the signal so it can be transmitted further. If you need greater distance, you have two choices: a signal booster or an active cable. Depending on the quality of the cable and other factors, you may be able to transmit video and audio over greater distances. HDMI 2.0: It is an enhanced version of HDMI that supports 4K at 60 frames per second. However, it is limited to 4K at 30 frames per second, which is less than optimal. The maximum length of a passive DisplayPort cable is at least 15 meters/33 feet. Several of the multiple HDMI standards have the same characteristics: HDMI 1.4: This is a legacy version of HDMI that does not support high dynamic range video. The longer the cable or the more data (higher resolution) you try to push through it, the more likely the signal will weaken and suffer from errors and interference. To make it easier to find the cable you need, the VESA DisplayPort Task Group gives transmission speed a name.įor more detail, see DisplayPort Cables and DisplayPort 2.0 Monitor Configurations below. Updates to the DisplayPort standard typically include a boost in transmission speed (also referred to as bandwidth). Raspberry Pi standard 40 pin GPIO header (fully backwards compatible with previous boards) 2 × micro-HDMI ports (up to 4kp60 supported) 2-lane MIPI DSI display port. Resolution, color depth, number of monitors, refresh rate are all dependent on how much data the cable can transmit. 1GB, 2GB, 4GB or 8GB LPDDR4-3200 SDRAM (depending on model) 2.4 GHz and 5.0 GHz IEEE 802.11ac wireless, Bluetooth 5.0, BLE. The primary difference between them is transmission speed. He also thinks you should check out his best-selling sci-fi novel and its sequel. Still have a question?

First, check out all the other articles he's written on topics like why all HDMI cables are the same, TV resolutions explained, LED LCD vs. HDMI cables are described as supporting different lists of features. "Shouldn't" being the key word - but then, that's HDMI. The HDMI specification has had a variety of versions, from 1.0 through 2.1. For now though, it's not worth worrying about.Īnd of course, all the versions are backward-compatible, so you can connect your HDMI 1.4 Blu-ray player to your HDMI 2.0b TV and you shouldn't have any issues. Will your next TV have HDMI 2.1? If you get one next year, maybe. The other reason is because the final 2.1 spec isn't finalized yet (as of this writing). Sure the grip is great… but why? This is one of the reasons why 2017s might have 2.0b, but none will likely have 2.1. It would be like Toyota putting racing tires on your Camry at the factory. Remember, even though your TV can only display 4K/60, to be "HDMI 2.1" the HDMI chips need to be able to handle 10K/120. The issue is the chips inside the TV itself, which have to be able to handle a lot more data. Changing from anything to 2.1 is highly unlikely.
