AMD gamers have a few more options, at least with RX 7000-series cards. You can find DisplayPort 2.1 monitors and TVs, if you look hard enough. Maybe. The Asus ROG Swift PG32UXQR for example supports DisplayPort 2.1, but it hasn't officially released yet (and it's not the same as the previous PG32UXQ). HDMI 2.1 connectivity is also sufficient, and there are more displays available. Keep in mind that maximum bandwidth of the RDNA 3 GPUs is 54 Gbps over DisplayPort 2.1, or 48 Gbps over HDMI 2.1, so it's not a huge difference. Most AMD RX 7900-series cards that we've seen include two DisplayPort 2.1 ports, and either two HDMI 2.1 or a single HDMI 2.1 alongside a USB Type-C connection. The stipulation that the DP_PWR wire be omitted from standard DisplayPort cables was not present in the DisplayPort 1.0 standard. However, DisplayPort products (and cables) did not begin to appear on the market until 2008, long after version 1.0 had been replaced by version 1.1. The DisplayPort 1.0 standard was never implemented in commercial products. [46] Resolution and refresh frequency limits [ edit ]
VESA released the DisplayPort 2.1 specification today. Typically when an industry group announces a new standard, it takes months or even years for products supporting the spec to be available to consumers. But DisplayPort 2.1 products are already available; in fact, you may already own some. VESA also declared today that any product that was already DisplayPort 2.0-certified before today's announcement is now DisplayPort 2.1-certified, too. All DisplayPort cables are compatible with all DisplayPort devices, regardless of the version of each device or the cable certification level. [42]
What's next for DisplayPort vs HDMI?
Primarily, you’ll hear about DisplayPort 1.2, 1.4, and 2.0 cables. Our recommendation is to get 1.4 and higher DisplayPort cables. DisplayPort version 1.4 is able to take advantage of 8K video resolutions and supports nearly all audio formats, making it a fine choice for most consumers. A new PlugTest is planned for March in 2021, in Taiwan, where the compliance spec should be completed. Three 10K ( 10240 × 4320) displays @ 60 Hz and 10 bpc (30 bit/px, HDR) RGB/Y′C BC R 4:4:4 color (with DSC) During those PlugTests, PC, chip, display and display chip vendors all come together to make sure the products work well together.
Not all DisplayPort cables are capable of functioning at the highest levels of bandwidth. Cables may be submitted to VESA for an optional certification at various bandwidth levels. VESA offers four levels of cable certification: Standard, DP8K, DP40, and DP80. [41] :§4.1 These certify DisplayPort cables for proper operation at the following speeds: 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, §4.1DisplayPort 2.0 will use the same DisplayPort connector and port as previous DisplayPort standards, but will also be available over USB-C and Thunderbolt connections using DisplayPort Alt Mode over USB. Like DP Alt Mode on previous DisplayPort standards, this version allows the transmission of audio, video, and data over a single USB cable, allowing for simple connecting of supporting displays. This can be particularly useful when connecting external monitors to laptops with limited port options, and for daisy-chaining multiple monitors together. There are a few terms in these specification tables which might have you scratching your head. They are HDCP, HDR, and WGC.I’ll briefly go into all these terms, to help you understand why they are awesome for your gaming experience. The Mini DisplayPort connector was developed by Apple for use in their computer products. It was first announced in October 2008 for use in the new MacBooks and Cinema Display. In 2009, VESA adopted it as an official standard, and in 2010 the specification was merged into the main DisplayPort standard with the release of DisplayPort 1.2. Apple freely licenses the specification to VESA.
Three 4K ( 3840 × 2160) displays @ 90 Hz and 10 bpc (30 bit/px, HDR) RGB/Y′C BC R 4:4:4 color (uncompressed) The answer, as always, is "it depends." What are you looking to do? For instance, you will have different needs depending on if you're gaming, photo editing, or just looking to hook your Mac up to something that works. Even if your monitor supports both connections, it may only support certain versions of each, which determines what resolution, refresh rate, and other features it can handle. Here's what you need to know.One cable is not necessarily better than the other across the board, but each does have its place. If you have the choice between DisplayPort 1.4 (or 1.4a) and HDMI 2.0, DisplayPort would be the better option. In other cases, if a monitor only gives you the choice between, say, HDMI 2.0 and DisplayPort 1.2, HDMI could be the way to go for the HDR support, as long as all your devices support the HDMI version in question. HDMI 2.1 can support 4K resolution at up to a previously impossible 144Hz, 4K resolution at 60Hz, and can even display 8K resolution at 60Hz. Display Stream Compression (DSC) lets it go further still, enabling 8K at 120Hz, or even 10K resolution at up to 100Hz, all without using chroma subsampling. DisplayPort version 1.4 was published 1 March 2016. [22] No new transmission modes are defined, so HBR3 (32.4 Gbit/s) as introduced in version 1.3 still remains as the highest available mode. DisplayPort 1.4 adds support for Display Stream Compression 1.2 (DSC), Forward Error Correction, HDR10 metadata defined in CTA-861.3, including static and dynamic metadata and the Rec. 2020 color space, for HDMI interoperability, [23] and extends the maximum number of inline audio channels to 32. [24] 1.4a [ edit ] The first version, 1.0, was approved by VESA on 3 May 2006. [6] Version 1.1 was ratified on 2 April 2007, [7] and version 1.1a was ratified on 11 January 2008. [8] 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?
Unidirectional– Although the dual-mode standard specifies a method for DisplayPort sources to output DVI/HDMI signals using simple passive adapters, there is no counterpart standard to give DisplayPort displays the ability to receive DVI/HDMI input signals through passive adapters. As a result, DisplayPort displays can only receive native DisplayPort signals; any DVI or HDMI input signals must be converted to the DisplayPort format with an active conversion device. DVI and HDMI sources cannot be connected to DisplayPort displays using passive adapters. DisplayPort version 1.2a was released in January 2013 [15] and may optionally include VESA's Adaptive Sync. [16] AMD's FreeSync uses the DisplayPort Adaptive-Sync feature for operation. FreeSync was first demonstrated at CES 2014 on a Toshiba Satellite laptop by making use of the Panel-Self-Refresh (PSR) feature from the Embedded DisplayPort standard, [17] and after a proposal from AMD, VESA later adapted the Panel-Self-Refresh feature for use in standalone displays and added it as an optional feature of the main DisplayPort standard under the name "Adaptive-Sync" in version 1.2a. [18] As it is an optional feature, support for Adaptive-Sync is not required for a display to be DisplayPort 1.2a-compliant. When DisplayPort 2.0 does arrive, expect it to be on desktop PCs and premium displays, before proliferating more widely in the years to come. You can also expect it to appear in business markets for ultra-high resolution displays in conference rooms and advertising systems. What's next for DisplayPort vs HDMI?To understand the above chart in context, we need to go deeper. What all digital connections — DisplayPort, HDMI and even DVI-D — end up coming down to is the required bandwidth. Every pixel on your display has three components: red, green, and blue (RGB) — alternatively: luma, blue chroma difference, and red chroma difference (YCbCr/YPbPr) can be used. Whatever your GPU renders internally (typically 16-bit floating point RGBA, where A is the alpha/transparency information), that data gets converted into a signal for your display. HDMI 2.1 offers a more straightforward 48Gbps of bandwidth, up from HDMI 2.0’s 18GBps. That seems like a big win for DisplayPort 2.0. After all, bandwidth is the key enabler of everything from more pixels to higher refresh and features like HDR. But the reality is more complicated. The standout feature of DisplayPort 2.0 is the major advances it makes in overall bandwidth. Where DisplayPort 1.4 offers a capable 32.4 Gbps maximum bandwidth (with a 25.92 Gbps maximum data rate due to encoding inefficiencies), DisplayPort has the option for more than double that. Its maximum total bandwidth is an astounding 80 Gbps (with a maximum total data rate of 77.37 Gbps). The FURUI Nylon presents us with a superb DisplayPort cable that is capable of producing an 8K resolution quality even at 120Hz. For the high-end monitors of the future, it can even go up to a whopping 16K. It can be hard to believe how high the quality of the FURUI’s resolution capacity is, far surpassing the needs of most consumers, but you can rest assured … the FURUI comes VESA certified. DSC can provide up to a 3:1 compression ratio by converting to YCgCo and using delta PCM encoding. It provides a "visually lossless" (and sometimes even truly lossless, depending on what you're viewing) result. Using DSC, 8K 120 Hz HDR is suddenly viable, with a bandwidth requirement of 'only' 42.58 Gbps.
