HDMI 2.1 could reinvent PC gaming, and all gaming laptops should have it

HDMI 2.1 made a big splash at CES 2021. It’s a strange thing to say about a port, but it just may end up having a bigger impact on PC gaming than any flashy new gaming laptop or even a graphics card.

It also might help overcome the barrier that has existed between PC and console gaming since the beginning. Here’s why HDMI 2.1 could finally unite gaming — and why all gaming PCs should support it moving forward.

Breaking down walls

A divide has always existed in gaming: Consoles are for the living room and televisions, PCs are for desks and monitors. They’ve evolved separate from one another, developing different tech to fit their specific needs. In recent years, that’s become especially important when it comes to ports.

PCs have gradually moved away from HDMI. You’ll still find HDMI 2.0 in laptops and desktop graphics cards, but most desktop gamers currently favor the fast refresh rates of DisplayPort. All gaming monitors have it, as do desktop graphics cards. DisplayPort 1.4 granted PCs the ability to do 4K at 120Hz, which is something only high-end PCs have been able to use relatively recently. DisplayPort also supports important syncing technology such as G-Sync or FreeSync, to smooth out gameplay.

In the console world, HDMI is still king. The main reason is that older consoles couldn’t make use of those resolutions and refresh rates anyway. But the Xbox Series X and PlayStation 5 change all that. They’re more like PCs than any console before them, and by adopting HDMI 2.1, they have the same support for 4K 120Hz as DisplayPort.

We’ve reached a convergence point. As HDMI 2.1 begins to roll out, there might not be much of an advantage to using DisplayPort over HDMI. That presents an incredible opportunity to increase the value of laptops and PC gaming as a whole.

Gaming laptops need to embrace HDMI 2.1

At CES 2021, just one gaming laptop announced support for HDMI 2.1, the Alienware m15 R4. That might not sound too promising, but all evolutions in technology start small, especially when it comes to changes in standards.

That’s especially true since only the most recent graphics upgrade to the Nvidia RTX 30-series is what enables gaming laptops to play in 4K for the very first time. Manufacturers are only just starting to put 4K 120Hz screens in laptops, such as the Asus ROG Zephryus Duo 15 SE.

Now, imagine for a moment that you have one of these powerful new HDMI 2.1 gaming laptops. You use it for work during the day, and then can freely switch between the gaming monitor in your office and the television in your living room. Your wireless keyboard and mouse connect automatically at your desk, and when you move to the couch, so do your controllers. It would make the portability of gaming laptops so important, especially in a world where you still can’t buy the latest consoles or desktop graphics cards.

Of course, we have a long way to go before HDMI 2.1 is fully embraced by the PC community. Not only is it currently only on the Alienware m15 R4, it’s only being applied to select monitors. It’s also not even a standard feature of all televisions.

Meanwhile, VESA will be surely be advancing its own technology into the future with DisplayPort 2.0, which could again increase bandwidth to keep it ahead of HDMI.

But there’s a much better chance of PCs adapting to HDMI 2.1 than television and consoles switching to DisplayPort or USB-C. It’s the one port that already exists on nearly every device where we need it. That makes HDMI 2.1 the one hope for unifying high-end gaming across the many different platforms where it currently exists.

This RTX 3070 gaming laptop deal for $1,000 officially wins Cyber Monday
Two models of the Asus TUF Dash against graphics on a background.

If you're shopping for a gaming laptop under $1,000, you know what to expect. An RTX 3050 or 3050 Ti in a very thick chassis. Well, that's where this Cyber Monday deal from Best Buy exceeds my expectations for what gaming laptops at this price can be.

The deal is for an Asus TUF Dash, which normally sells for $1,500. Thanks to a discount of $500, though, this powerful gaming laptop now lands just under $1,000. That's an incredible value, considering it packs an RTX 3070 inside. And that GPU really does make all the difference in game performance.

Why DisplayPort 2.1 could become a big deal for PC gaming in 2023
Cable management on the Samsung Odyssey Neo G8.

DisplayPort 2.1 became a much bigger talking point than expected when AMD revealed its upcoming RX 7900 XTX and RX 7900 XT GPUs. It's the latest standard from DisplayPort, a revision to the 2.0 spec released in 2019, and it's a natural inclusion for next-gen GPUs. There's just one problem -- Nvidia's behemoth RTX 4090 still uses DisplayPort 1.4a.

Although the 1.4a spec is still more than enough for most people, the inclusion of DisplayPort 2.1 does give AMD an advantage this generation. No, I'm not here to sell you on 8K gaming -- in some parts of the world, 8K may not even be possible -- but for a crowd of competitive gamers and VR enthusiasts, DisplayPort 2.1 could mark a major shift.

With DisplayPort 2.1, longer cables won’t reduce throughput
DisplayPort Cable

The Video Electronics Standards Association (VESA) today announced the release of DisplayPort 2.1. It brings a few improvements over DisplayPort 2.0, such as tighter compliance with USB Type-C and USB4 PHY specifications, improved connectivity through DisplayPort tunneling over USB4, and longer cable lengths while maintaining high throughput.

Hot off the heels of DisplayPlay 2.0 released earlier this year, DisplayPort 2.1 facilitates greater PHY toward USB Type-C and USB4 PHY specifications. The new version has also added a DisplayPort bandwidth management feature that allows DisplayPort tunneling to work together with other I/O traffic over USB4 with great efficiency.
