Hyper's Latest Hubs Let You Connect Two 4K Displays to an M1 MacBook Using a Single Port

If MacOS properly supported the DisplayPort MST industry standard, Mac users would be able to daisy chain DP monitors or use any of the available MST hubs on the market. When looking at DP MST hubs from different manufacturers, there is usually a “Not compatible with Mac” warning on the page.

This is not a hardware compatibility issue since an Intel Mac booted into Windows works with MST just fine. What is Apple’s reason for still not supporting MST after all these years? It is some petty attempt to “convince” people to buy Thunderbolt monitors?

Forget the hub. Where can I buy cables like that? No snaking and curling and overlapping. They just sit there in perfectly straight paths, without tape or clips or anything, and at the perfect length! Wow! The future is now.

Only one HDMI port offers 60Hz 4K, the other is 30Hz. Can the M1 Macbook Air/Pro even power 2 x 60Hz 4K displays?

One of the 2 displays being limited to 30Hz should make this a non-starter for most people.

30Hz vs 60Hz for a computer monitor is a big deal. This technical compromise should not be underestimated. It should be mentioned in the article IMO.

EDIT: Also, I'd be interested in learning more about this "InstantView" technology. The official website doesn't properly explain what it is. Does it compress the image? If so, is the compression lossy? Should be a pretty important factor in your buying decision as well.

I agree. 4K at 30Hz is absolutely horrible.

Is there any details on HOW they're doing this?

Given that nothing has come up before, I have difficulty believing that they're actually getting the OS to output a 3rd display without additional drivers.

Now, what they *could* be doing is: The M1 can output 6K 60Hz (20,358,144 pixels), which is sufficient to run TWO 4K monitors (8,294,400 pixels each, 16,588,800 pixels total) worth as a *single display*, and their hardware is then chopping that display down to TWO separate monitors? Perhaps the 30Hz is a limitation of their chopping silicon that breaks the single display into two???

Hyper says both hubs deliver dual 4K HDMI video output over a single USB-C connection to M1 MacBook models by using a combination of both DisplayPort Alt Mode and SiliconMotion InstantView plug-and-play video technology ('https://www.siliconmotion.com/events/instantview/'). After connecting the hub to the Mac, users must open the HyperDisplay app that appears on the desktop.

It's using USB data for the second HDMI port, the first uses DP Alt mode. So with the M1 you're using up the 1 external display limit on DP Alt, and the other is a virtual graphics card connected over USB.
