DisplayPort

If the goods are incomplete or there is a shortfall you notify us within 3 days of receiving the goods HDMI cable requirements have changed over time, just like DisplayPort. One of the big advantages is that high quality HDMI cables can be up to 15m (49.2 feet) in length — five times longer than DisplayPort. That may not be important for a display sitting on your desk, but it can definitely matter for home theater use. Originally, HDMI had two categories of cables: category 1 or standard HDMI cables are intended for lower resolutions and/or shorter runs, and category 2 or “High Speed” HDMI cables are capable of 1080p at 60 Hz and 4K at 30 Hz with lengths of up to 15m. Standard DisplayPort cable connections do not use the DP_PWR pin. Connecting the DP_PWR pins of two devices directly together through a cable can create a short circuit which can potentially damage devices, since the DP_PWR pins on two devices are unlikely to have exactly the same voltage (especially with a ±10% tolerance). [45] For this reason, the DisplayPort 1.1 and later standards specify that passive DisplayPort-to-DisplayPort cables must leave pin 20 unconnected. [8] : §3.2.2 More often than not, if you’re connecting something to a television, HDMI will be your best, and likely only, bet. Most PC monitors will also include an HDMI input. The good news, where it comes to 1.4 versus 2, is that you don’t need to rush out and buy new cables. To take advantage of the 2.0 specyou just need both devices on each end of the cable to be 2-compatible. Any HDMI cable will do, and we’ve already seen that there’s no difference in HDMI cable quality. The DP8K certification was announced by VESA in January 2018, and certifies cables for proper operation at HBR3 speeds (8.1 Gbit/s per lane, 32.4 Gbit/s total). [43]

or 20 Gbit/s data rate per lane; 1, 2, or 4 lanes; (effective total 5.184, 8.64, 17.28, 25.92, or 77.37 Gbit/s for 4-lane link); 2 or 720 Mbit/s (effectively 1 or 576 Mbit/s) for the auxiliary channel. I know that HDMI can be very slow (depending on monitor)... sometimes as much as 5 seconds to see the new source. I assumed that was content protection built into the standard and/or slow decoder ASIC. so what I'm trying to find out is if there is another adapter i could use to get the second monitor to connect and work properly. I will say that I have an Acer XB280HK 4K60 G-Sync display that only has a single DisplayPort input, and it powers up or wakes from sleep almost instantly. I have an Acer G-Sync Ultimate 4K 144Hz HDR display meanwhile that takes about 7 seconds to wake from sleep. Rather annoying. To support a particular format, the source and display devices must both support the required transmission mode, and the DisplayPort cable must also be capable of handling the required bandwidth of that transmission mode. (See: Cables and connectors)DisplayPort (DP): The best connector for an audio and video signal, and can transmit 144Hz up to 4K a b c d e Although this format slightly exceeds the maximum data rate of this transmission mode with CVT-R2 timing, it is close enough to be achieved with non-standard timings Mobile High-Definition Link is an interface created for portable devices including mobile phones. MHL can be thought of as a spin-off version of HDMI. It was first proposed by Silicon Image which also had a significant contribution in the development of HDMI. This exemplifies why DisplayPort cables are not classified by "version"; although DSC was introduced in version 1.4, this does not mean it needs a so-called "DP 1.4 cable" (an HBR3-rated cable) to function. HBR3 cables are only required for applications which exceed HBR2-level bandwidth, not simply any application involving DisplayPort 1.4. If DSC is used to reduce the bandwidth requirements to HBR2 levels, then an HBR2-rated cable will be sufficient.
