About this deal

Just about the same as any of the other 1.4 DisplayPort cables on this list—4K@120Hz and 8K@60Hz really shouldn’t be making you blink an eye at this point. The wires themselves are quite standard. Three QHD ( 2560 × 1440) @ 120 Hz and 8 bpc (24 bit/px, SDR) RGB/Y′C BC R 4:4:4 color (uncompressed) The DisplayPort main link is used for transmission of video and audio. The main link consists of a number of unidirectional serial data channels which operate concurrently, called lanes. A standard DisplayPort connection has 4 lanes, though some applications of DisplayPort implement more, such as the Thunderbolt 3 interface which implements up to 8 lanes of DisplayPort. [39] :4

Also making DisplayPort 2.0 interesting is boosted support for multi-monitor setups. This tech is already present in older DisplayPort versions, but due to the limited bandwidth, it's mostly useful for lower-resolution monitors. The max effectiveness you could get out of multi-monitor setups with DisplayPort 1.4a was two 1440p panels at 60 Hz without compression. On October 17, 2022, VESA announced that it has released the specifications for DisplayPort 2.1 and that this latest standard of DisplayPort is going to add significant improvements toDisplayPort tunneling over USB4 along with a few other key features, like DisplayPort bandwidth management which further increases the efficiency of the video data stream. What does this mean? It's likely that we'll be waiting on a next-generation graphics card of some kind before we see any DisplayPort 2.0 Nvidia graphics cards, or DisplayPort 2.0 AMD GPUs. Those may debut at the end of 2021, but are more likely in early 2022. DisplayPort 2.0, USB-C, and Thunderbolt Cables certified DP40 will support everything up to and including the UHBR 10 transmission mode, giving it a maximum bandwidth of 40 Gbps. DP80 cables will support all seven DisplayPort transmission modes, including the highest bandwidth UHBR 13.5 and UHBR 20, giving it a maximum bandwidth of 80 Gbps.One 16K ( 15360 × 8640) display @ 60 Hz with 10 bpc (30 bit/px, HDR) RGB/Y′C BC R 4:4:4 color (with DSC) In the specification table, I mention “multi-stream” which is referring to the cable’s ability to daisy chain monitors in sequence. This can only be achieved with DisplayPort and means thatnot every monitor needs to be directly plugged into your graphics card, unlike with HDMI. One connection is sufficient and able to be continued from one monitor to the next. Cable management ismuch easier and you get amazing connectivity on all your monitors. That is *chefs kiss* indeed! Cables Summed Up

The debate of HDMI 2.0 vs. DisplayPort 1.4 was fierce, and the DisplayPort 2.0 vs. HDMI 2.1 one will be much the same, although in both cases the more capable connection was clear. While HDMI 2.0 and 2.1 offer ARC and eARC technology for simplifying home audio connections, they fall far behind their DisplayPort counterparts in overall bandwidth. It should also be noted that the use of Display Stream Compression (DSC), introduced in DisplayPort 1.4, greatly reduces the bandwidth requirements for the cable. Formats which would normally be beyond the limits of DisplayPort 1.4, such as 4K (3840 × 2160) at 144 Hz 8 bpc RGB/Y′C BC R 4:4:4 (31.4 Gbit/s data rate when uncompressed), can only be implemented by using DSC. This would reduce the physical bandwidth requirements by 2–3×, placing it well within the capabilities of an HBR2-rated cable. The HDMI cable has been developed to meet the ever-increasing demands of HD viewing, all the way up to 8K. Currently, we are on HDMI 2.1 which was announced in 2017 and made available towards the latter end of 2020. HistoryDisplayPortat a Glance DisplayPort 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.

Which Cable Should You Choose?

DisplayPort 2.1 has tightened its alignment with the USB Type-C specification as well as the USB4 PHY specification to facilitate a common PHY servicing both DisplayPort and USB4. In addition, DisplayPort 2.1 has added a new DisplayPort bandwidth management feature to enable DisplayPort tunneling to coexist with other I/O data traffic more efficiently over the USB4 link. 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. That also kind of proves out the compliance testing so we can certify equipment," Wiley explained. "So without being able to test a lot of different things and seeing how things work together, it's kind of hard to finish that whole compliance program. So that's been part of the problem. " When looking at the specs, DisplayPort is the way to go if you are after some hardcore gaming. Working your way through Halo Infiniteonasubstandard definition is not how we want to play.On the other hand, if you’re using your monitor for more run-of-the-mill tasks, like staring at endless spreadsheets, then an HDMI cable is the better option.The latest generation is more widely available and hasbetter bandwidth than DisplayPort 1.4. What about 4K and Ultra HD? Unavailable on USB-C– The DisplayPort Alternate Mode specification for sending DisplayPort signals over a USB-C cable does not include support for the dual-mode protocol. As a result, DP-to-DVI and DP-to-HDMI passive adapters do not function when chained from a USB-C to DP adapter.

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) In April 2013, VESA published an article stating that the DisplayPort cable certification did not have distinct tiers for HBR and HBR2 bandwidth, and that any certified standard DisplayPort cable—including those certified under DisplayPort 1.1—would be able to handle the 21.6 Gbit/s bandwidth of HBR2 that was introduced with the DisplayPort 1.2 standard. [42] The DisplayPort 1.2 standard defines only a single specification for High Bit Rate cable assemblies, which is used for both HBR and HBR2 speeds, although the DP cable certification process is governed by the DisplayPort PHY Compliance Test Standard (CTS) and not the DisplayPort standard itself. [37] :§5.7.1, §4.1 The DisplayPort AUX channel is a half-duplex (bidirectional) data channel used for miscellaneous additional data beyond video and audio, such as EDID ( I 2C) or CEC commands. [8] :§2.4 This bidirectional data channel is required, since the video lane signals are unidirectional from source to display. AUX signals are transmitted across a dedicated set of twisted-pair wires. DisplayPort 1.0 specified Manchester encoding with a 2 MBd signal rate (1 Mbit/s data rate). [8] :§3.4 Version 1.2 of the DisplayPort standard introduced a second transmission mode called FAUX (Fast AUX), which operated at 720 MBd with 8b/10b encoding (576 Mbit/s data rate), [37] :§3.4 but it was deprecated in version 1.3. DisplayPort 2.0 monitors were expected to become widely available in the latter months of 2020, but after a delay announced by VESA, they are now slated to arrive in the second half of 2021. Are There Any DisplayPort 2.0 Graphics Cards? 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.DSC has the potential to make DisplayPort 2.0 even more capable, with support for up to three 10K screens running at 60 Hz with HDR on a single DisplayPort 2.0 connection. It will also support twin 8K displays at up to 120Hz with HDR and 10 bits per pixel (bpc), or a single 16K display at 60Hz, with HDR and 30 bpc. DisplayPort 2.0 vs HDMI 2.1
