    You can only do that because your monitors are not high resolution and high refresh rate. The data cap for usb-c is not that high.

      USB-C is just a connector, but Thunderbolt 5 uses it and for asymmetric uses (e.g. a monitor) it can hit 120Gbps.

      Isn’t that going to support most monitors?

        Please, list the devices that you know have tb5.

        Also, that’s the total bandwidth in a best case scenario. You’re not factoring in that you’ll need to share that with all of the devices in a hub. That’s without mentioning that you need the hub (which also has a cost).

          All high quality peripheral docks support Thunderbolt. Thunderbolt 5 docks began to release last month. You can connect the devices to the dock using USB-C, then just use one Thunderbolt cable to connect the dock to your Mac to prevent a bottleneck.

            So, barely a handful? Great. How much do they cost? And how much does it cost to just use the cable your devices come with?

              The countless remaining docks support Thunderbolt 4, which at 40 Gb/s is still twice as fast as USB-C 3.2 Gen 2x2.

              They range from $49-$299, depending on the features and number of ports needed. If you’re using the native HDMI port on your MacBook Pro, it’ll be on the low end of the price range.

              The only cable that comes with a MacBook Pro is a USB-C charging cable.

                Awesome. But what I think is ideal is having multiple ports which, in addition, would give you more bandwith, more reliability and more flexibility than a single high bandwidth hub.

                You misread. I was referring to the cables the devices you use with your laptop come with.

                  MacBook Pro comes with three Thunderbolt 5/USB-C ports (120 Gb/s), HDMI 2.1b, MagSafe 3, and a 3.5 mm headphone jack. Trading a USB-C port for USB-A means potentially downgrading a USB-C capable device to USB-A with an adapter. The opposite results in better performance, and the adapters will continue to be useful as long as you own USB-A devices. When computers only have USB-C ports, your other adapters will be useless.

                  As for cables, I replace them rather than using adapters. Monoprice.com sells quality cables relatively inexpensively.

                    Again, missing the point. There’s nothing you need to “trade”. They could simply add more ports.

                    Monoprice is not a worlwide brand and buying more stuff is not a sensible solution to a manufactured problem.

      Can you break this down?

      The 2017 model pictured in this post supported Thunderbolt 3, which was a 40 gbps connection. Supported display modes included up to 4k@120, 2x4k@60, or 5k@60, which was better than the then-standard HDMI 2.0.

      What combination of resolution, frame rate, and color depth are you envisioning that having a dock handle a gigabit Ethernet connection, analog audio would require scaling down the display resolution through the same port?

      By 2021, the MacBook Pros were supporting TB4, and the spec sheets on third party docking stations were supporting 8k resolutions, even if Macs themselves only supported 6k, or up to 4x4k.

      Even if we talk about DisplayPort Alt Mode, a VESA standard developed in 2014, and supported in the 2017 models pictured in this post, that’s just a standard DP connection, which in 2017 supported HDR 5k@60. But didn’t support a whole separate dock with networking and USB ports.

        Right, for a single device.

        What combination of resolution, frame rate, and color depth are you envisioning that having a dock handle a gigabit Ethernet connection, analog audio would require scaling down the display resolution through the same port?

        Dual 4k120 would already saturate the bandwith. Regarding networking, gigabit is pretty slow for LAN depending on your workload. If you were to require 10gbit, you’d be SOL.

        By 2021, the MacBook Pros were supporting TB4, and the spec sheets on third party docking stations were supporting 8k resolutions, even if Macs themselves only supported 6k, or up to 4x4k.

        Did you read the specs in your link? Even with that TB4 dock you wouldn’t be able to do dual 4k120.

        I really don’t get trying to justify manufacturers forcing you to buy an additional device to get the same ports they could provide natively without using a hub/dock. It’s a pretty submissive attitude.

          Dual 4k120 would already saturate the bandwith.

          What would you use to drive dual 4k/120 displays over a single cable, if not Thunderbolt over USB-C? And what 2017 laptops were capable of doing that?

          Even if we’re talking about two different cables over two different ports, that’s still a pretty unusual use case that not a lot of laptops would’ve been capable of in 2017.

            4k120 panels weren’t even available in 2017 afaik. But you could do dual 4k120 with one hdmi 2.1 and 1 displayport 1.4 so just need 2 video outputs from your laptop (which used to be pretty common).

            Please note that we’re having this discussion in 2024 and I’m talkimg about use cases in 2024. I don’t really see the point in talking about what you would theoretically do 6 years ago with panels that weren’t even available.
