VESA today announced that it has released DisplayPort Alt Mode 2.0, paving the way for future USB4 devices to support DisplayPort 2.0.


Announced in June 2019, DisplayPort 2.0 has a max effective bandwidth of 77.4 Gbps, nearly triple that of DisplayPort 1.4. The new standard enables support for displays with up to 16K resolution, higher refresh rates, HDR support at higher resolutions, improved support for multiple display configurations, and more.

USB4 converges the Thunderbolt and USB protocols as part of Intel's goal to make Thunderbolt available on a royalty-free basis, which should result in wider and cheaper availability of Thunderbolt accessories like docks and eGPUs.

USB4 uses the USB-C connector design and is backwards compatible with USB 3.2 and USB 2.0.

Apple will likely adopt USB4 in future Macs. VESA expects the first products incorporating DisplayPort Alt Mode 2.0 to appear on the market in 2021.

Good, nothing makes me want to rip my hair out more than the price of thunderbolt docks (even thunderbolt 2 docks - 6 year old tech are still way overpriced)

This is likely what Apple is waiting on before they upgrade the iMac and iMac Pro. Apple likes to have something that differentiates each product and form factor. I am seriously thinking about getting a iMac as my next computer if it uses the XDR design and reduced the bezels and chin.

Agreed. The current iMac looks dated. I can see the Mac Pro design language trickling down into consumer products.

I'm guessing the main factors of Thunderbolt dock pricing were:

  • relatively low volume
  • many purchasers are Apple customers and willing to pay a premium
  • lower-priced, higher-volume USB dock alternatives exist

Not likely.

Volume is extremely high ...
Lenovo ThinkPad T480s/T490 and a few others have 2x Thunderbolt 3 ports already and docks.
HP EliteBook 840 G5/G6, EliteBook DragonFly (of which others: EliteBook 1030/1040 G5+G6, 830 G4 and a few others) ALL have 1 or 2 Thunderbolt 3 ports and about 3 docks already that use this for corporate deployment.
Dell XPS 13 9300 (2020 model) and the XPS 13 2-in-1 released late 2019 BOTH ONLY have Thunderbolt 3 (x2) ports.

The upcoming EliteBook and ThinkPad T lineups will ONLY have Thunderbolt 3 or USB-C4 ports so those traditional and finnicky corporate 'Docks' will be a thing of a past for older laptops going forward.

Volume is already there, at least with shipping to retailers (brick and online).

Agreed on point 2 however the licensing is the cost.

One thing I thought TB3 had was connection security - I see this in HP laptops - yet I don't see this in the USBC4 spec.

USB 4 would be great for the next iPad Pro. I'm not expecting it though in that iteration.

However, I'd be extremely pleased in the next iPad Pro with Thunderbolt 3 even if isn't official USB 4.

Would usb4 cables work though? Are they functionally the same, or just have the possibility of working if the manufacturer wishes to?

Not sure how a bunch of laptops that sell less than MacBooks are proof that "volume is extremely high". EliteBook? ThinkPad? Seriously? Those aren't mass-market. The XPS kind of is, but most of the existing ones aren't Thunderbolt.

And none of that negates my third point: you can just use a USB-C dock regardless. Which almost everyone ends up doing.

For Thunderbolt demand? Where?

The cost is zero.

Unfortunately, I don’t believe Apple is going to release a single Intel-based Mac with USB 4 onboard, instead opting to use it exclusively with ARM/Arm-based Macs and the iPad Pro post 2021/2022. Apple wants to move users over to the ARM/Arm side as quickly as possible. At least that’s what I would do if I was in charge.

This is the news I’ve been looking for, but I am unclear on one thing: does USB-4 itself have this bandwidth or is TB4 integration necessary? (Edit: Is DP 2.0 now an independent part of USB 4 or is it part of TB 4? How is DP 2.0 achieving the extra bandwidth?)

I thought TB4 retained the same 40Gbps maximum throughput as TB3.

Sounds nice for eGPUs. I currently use a Razer Core X eGPU with my 2018 15” MacBook Pro, it works really well in either Mac OS X or booted into Windows for games. I stuck a Vega 56 in it last year, lots of bang for the buck for a couple hundred bucks.

Volume on the computer side doesn't equal volume on the peripheral side, ie, how many TB peripherals are actually sold. And we are talking here about the price of TB peripherals and thus how many of those are being sold is the relevant factor here when trying to explain the high price of said peripherals.

Of course, there is the chicken-and-egg problem. If prices are high, few are getting sold. And if few are sold, prices remain high. But the fact that USB-C speeds are good enough for most people is probably the main factor why so few TB peripherals are being sold.

The cost is zero.
My wife works for a hospital system and they equipped her Lenovo Thinkpad with a Lenovo TB3 dock to allow her to have a multi-monitor setup, which shocked the hell out of me. I suspect there are more corporate purchasers of TB3 docks than we may suspect.

Her previous employer gave her a Dell laptop with a USB-C dock which had a similar effect on my perceptions of how much these technologies are evolving in the PC marketplace.

Items marketed exclusively to the Mac crowd always carry a higher and sometimes unnecessary price bumps to appear as though we are getting special items the PC crowd do not, which ain’t necessarily so.

I dunno; I don't see it a lot. A USB-C dock will do fine for many purposes.

Sure, but those are like a third of the price, if that.

Well, especially in the Thunderbolt 2 era, Thunderbolt outside of Macs was rare.

And in the Thunderbolt 3 era, actual Thunderbolt devices are still relatively rare compared to USB-C ones.

Which was really my original point. Even if computers increasingly have Thunderbolt 3, people rarely use it for that.

I suspect that as long as cables are created to spec, they shouldn't be a problem. The main problem is USB cables are often sub-par.
