<p>A new generation of cables is just cresting the horizon and it’s bringing with it more bandwidth, features, and capabilities than anything that’s come before.
<a href="/pc-1326-139-braided-48gbps-ultra-8k-hdmi-cable-with-8k-120hz-and-hdr.aspx">HDMI 2.1 cables</a> are already a mainstay of new-generation console gaming, but
<u><a title="CableMatters.com" href="/blog/DisplayPort/what-is-displayport-2-0" target="_blank">DisplayPort 2.0 may not be too far away</a>. </u> When DisplayPort 2.0 arrives, it will enable a whole new theatre of high frame rates
at ultra high resolutions for high-end gaming PCs.</p>
<p> Like the <a href="/blog/HDMI/displayport-vs-hdmi">HDMI 2.0 vs DisplayPort 1.4</a> debate that came before it, HDMI 2.1 vs. DisplayPort 2.0 will be the next great cable head-to-head.</p>
<p> </p>
<div class="video-responsive"><iframe title="YouTube video player" src="https://www.youtube.com/embed/oP6KxAwb-qA" width="560" height="315" frameborder="0" allowfullscreen="allowfullscreen"></iframe></div>
<p> </p>
<h2><strong>HDMI 2.1 – The Best Right Now</strong></h2>
<p>HDMI 2.1 was a monumental leap in performance and features over its predecessors unlike any of the generational improvements that came before. Where HDMI 2.0 has a maximum bandwidth of just 18 Gbps,
<a href="/blog/HDMI/what-is-hdmi-2-1">HDMI 2.1 can support as much as 48 Gbps</a>. That enables support of higher resolutions at higher refresh rates, with and without HDR’s demands for additional color depth.</p>
<p>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 30Hz.
<a title="CableMatters.com" href="/blog/DisplayPort/what-is-display-stream-compression" target="_blank">Display Stream Compression</a> (DSC) lets it go further still, enabling 8K at 120Hz, or even 10K resolution at up to 100Hz, all
without using chroma subsampling.</p>
<p>The HDMI 2.1 standard also brought with it a number of new features, including support for enhanced audio return channel, or eARC, where 5.1 and 7.1 surround sound data can be transmitted between an HDMI 2.1 source and a bespoke audio
system over a single HDMI 2.1 cable. It also supports variable refresh rate and auto low latency mode for improved performance when gaming.</p>
<p><a title="CableMatters.com" href="/pc-1337-139-certified-active-ultra-high-speed-hdmi-cable-fiber-active-optical-8k-hdmi-cable.aspx" target="_blank">HDMI 2.1 cables</a> are fully backward compatible with older HDMI standards, but they
are necessary to enjoy the full bandwidth of HDMI 2.1. HDMI 2.0 cables can enjoy slightly increased bandwidth when connected to HDMI 2.1 connectors, but don’t come close to realizing the standard’s true potential</p>
<p>All of this makes HDMI 2.1 the best and most capable cable standard available today in 2021. Once DisplayPort 2.0 monitors and PCs start to appear though, it will be in for some stiff competition. In the desktop space, at least, HDMI
2.1 vs. DisplayPort 2.0 may not be much of a fight at all.</p>
<h2><strong>DisplayPort 2.0 – 8K Gaming and Beyond</strong></h2>
<p>If HDMI 2.1 is the gold standard for 4K gaming and ultra high definition movies, DisplayPort 2.0 could be the cable that enables 8K gaming and more. It almost trebles the maximum data of
<a title="CableMatters.com" href="/pc-998-154-vesa-certified-displayport-14-cable-8k-60hz-ready.aspx" target="_blank">DisplayPort 1.4 cables</a>, and near-doubles that of HDMI 2.1, reaching as high as 80 Gbps.</p>
<p><img src="/blog/image.axd?picture=/ArticlePhotos/HDMI2.1-vs-DisplayPort2.0_2.jpg" alt="HDMI 2.1 vs DisplayPort 2.0 bandwidth" width="833" height="446"></p>
<p>This enormous bandwidth makes it possible for a DisplayPort 2.0 connection to handle 4K resolution at 240Hz, 5K at 180Hz, and even 8K at up to 85Hz – all without using DSC. HDR content reduces these maximums slightly, but it can still
do 8K at 60Hz even with HDR enabled.</p>
<p>As much as 8K is a new standard with very little compatible content or displays to enjoy it on just yet, it will likely become a more mainstream standard in the years to come. When that happens, there won’t be any question about which
cable you’ll use. For HDMI 2.1 vs. DisplayPort 2.0; DisplayPort is the obvious choice.</p>
<p>That extreme bandwidth also unlocks much higher resolutions: twin 4K displays at 144Hz with no compression, a 10K display at 60Hz with no compression, and even a 16K display at 60Hz with HDR when DSC is enabled.</p>
<p>Although these resolutions aren’t even on the horizon for traditional TVs, there is the potential for this sort of extreme resolution for virtual and augmented reality displays – even if no graphics card exist as of yet that could meet
such high frame rate and resolution demands.</p>
<p>As with previous generations of DisplayPort technology, it will also be possible to leverage DisplayPort 2.0 in DisplayPort Alt Mode using alternative
<a title="CableMatters.com" href="/Cable-Matters-USB-C.aspx" target="_blank">connectors like USB-C</a> and <a href="/pc-1352-132-intel-certified-thunderbolt-4-usb-c-cable-supporting-100w-charging.aspx" target="_blank">Thunderbolt</a>.
</p>
<p>There is no eARC-like support with DisplayPort 2.0, and it doesn’t have a big feature overhaul compared to its predecessors, but one new feature it does enjoy is Panel Replay. That helps optimize the power and thermal demands of
connected devices so that they are only forced to render the portion of the screen that has changed since the previous frame. This is targeted at saving power in smaller connected devices like all-in-one PCs and laptops, but there is
potential for a slight performance uplift for all devices that make use of it, too.</p>
<p><img src="/blog/image.axd?picture=/ArticlePhotos/HDMI2.1-vs-DisplayPort2.0_3.jpg" alt="HDMI 2.1 vs DisplayPort 2.0 features" width="833" height="409"></p>
<h2><strong>HDMI 2.1 vs DisplayPort 2.0 in 2021</strong></h2>
<p>The big downside to DisplayPort 2.0 in 2021, is that it’s not available yet. Not on devices, not on displays, and not in cable form. VESA has suggested it could start showing up before the end of the year, though. For now, HDMI 2.1 is
much more readily available and is very much viable as a solution for all sorts of high-end media and gaming needs.</p>
<p><img src="/blog/image.axd?picture=/ArticlePhotos/HDMI2.1-vs-DisplayPort2.0_4Fix.jpg" alt=""></p>
<p>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 <a href="/Cable-Matters-B2B.aspx">appear in business markets</a>
for ultra high resolution displays in conference rooms and advertising systems.</p>

HDMI 2.1 VS. DISPLAYPORT 2.0
By Cable Matters / Aug 12, 2021 / BLOG / DisplayPort
share
Facebook Twitter Google + LinkedIn Pinterest Email Share...
A new generation of cables is just cresting the horizon and it’s bringing with
it more bandwidth, features, and capabilities than anything that’s come before.
HDMI 2.1 cables are already a mainstay of new-generation console gaming, but
DisplayPort 2.0 may not be too far away. When DisplayPort 2.0 arrives, it will
enable a whole new theatre of high frame rates at ultra high resolutions for
high-end gaming PCs.
Like the HDMI 2.0 vs DisplayPort 1.4 debate that came before it, HDMI 2.1 vs.
DisplayPort 2.0 will be the next great cable head-to-head.
HDMI 2.1 – THE BEST RIGHT NOW
HDMI 2.1 was a monumental leap in performance and features over its predecessors
unlike any of the generational improvements that came before. Where HDMI 2.0 has
a maximum bandwidth of just 18 Gbps, HDMI 2.1 can support as much as 48 Gbps.
That enables support of higher resolutions at higher refresh rates, with and
without HDR’s demands for additional color depth.
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 30Hz. 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.
The HDMI 2.1 standard also brought with it a number of new features, including
support for enhanced audio return channel, or eARC, where 5.1 and 7.1 surround
sound data can be transmitted between an HDMI 2.1 source and a bespoke audio
system over a single HDMI 2.1 cable. It also supports variable refresh rate and
auto low latency mode for improved performance when gaming.
HDMI 2.1 cables are fully backward compatible with older HDMI standards, but
they are necessary to enjoy the full bandwidth of HDMI 2.1. HDMI 2.0 cables can
enjoy slightly increased bandwidth when connected to HDMI 2.1 connectors, but
don’t come close to realizing the standard’s true potential
All of this makes HDMI 2.1 the best and most capable cable standard available
today in 2021. Once DisplayPort 2.0 monitors and PCs start to appear though, it
will be in for some stiff competition. In the desktop space, at least, HDMI 2.1
vs. DisplayPort 2.0 may not be much of a fight at all.
DISPLAYPORT 2.0 – 8K GAMING AND BEYOND
If HDMI 2.1 is the gold standard for 4K gaming and ultra high definition movies,
DisplayPort 2.0 could be the cable that enables 8K gaming and more. It almost
trebles the maximum data of DisplayPort 1.4 cables, and near-doubles that of
HDMI 2.1, reaching as high as 80 Gbps.
This enormous bandwidth makes it possible for a DisplayPort 2.0 connection to
handle 4K resolution at 240Hz, 5K at 180Hz, and even 8K at up to 85Hz – all
without using DSC. HDR content reduces these maximums slightly, but it can still
do 8K at 60Hz even with HDR enabled.
As much as 8K is a new standard with very little compatible content or displays
to enjoy it on just yet, it will likely become a more mainstream standard in the
years to come. When that happens, there won’t be any question about which cable
you’ll use. For HDMI 2.1 vs. DisplayPort 2.0; DisplayPort is the obvious choice.
That extreme bandwidth also unlocks much higher resolutions: twin 4K displays at
144Hz with no compression, a 10K display at 60Hz with no compression, and even a
16K display at 60Hz with HDR when DSC is enabled.
Although these resolutions aren’t even on the horizon for traditional TVs, there
is the potential for this sort of extreme resolution for virtual and augmented
reality displays – even if no graphics card exist as of yet that could meet such
high frame rate and resolution demands.
As with previous generations of DisplayPort technology, it will also be possible
to leverage DisplayPort 2.0 in DisplayPort Alt Mode using alternative connectors
like USB-C and Thunderbolt.
There is no eARC-like support with DisplayPort 2.0, and it doesn’t have a big
feature overhaul compared to its predecessors, but one new feature it does enjoy
is Panel Replay. That helps optimize the power and thermal demands of connected
devices so that they are only forced to render the portion of the screen that
has changed since the previous frame. This is targeted at saving power in
smaller connected devices like all-in-one PCs and laptops, but there is
potential for a slight performance uplift for all devices that make use of it,
too.
HDMI 2.1 VS DISPLAYPORT 2.0 IN 2021
The big downside to DisplayPort 2.0 in 2021, is that it’s not available yet. Not
on devices, not on displays, and not in cable form. VESA has suggested it could
start showing up before the end of the year, though. For now, HDMI 2.1 is much
more readily available and is very much viable as a solution for all sorts of
high-end media and gaming needs.
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.
