They could have made it stream wirelessly from your MacBook

yeah, no. People really don't understand how much bandwidth you actually need to stream even normal 4k 60hz video, let alone something like this. For reference, when I was figuring out how to dump my pc in the basement and have the monitor in my office, I had to run 12-strand fiber cables to do it.

Parsec?

I've tried several remote desktop apps but the compression artefacts very quickly give me a headache. So I splurged for MTP cables and the display port dongles, and it works like a dream. Also, MTP connectors are pure fibre porn.

Yeah, no. Done it with WiFi 6, no problem. Meta has had Air Link for years. Works fine. You don't understand how much bandwidth you actually need.

you need about 20 gigabits per second for 4k 60hz. Or more, for higher resolutions and refresh rate - which vision pro has, compared to ~6 gigabits per second, that you need for your quest pro's resolution. That's why they make these.

And having compressed video streaming to a VR device sounds like my worst nightmare.

Wifi 7 has a peak rate of 40 Gbps.

Maybe it does, and it still would (probably) not be enough for 2 4k 90hz displays that this has. And even if it is, the majority of people don't really have a 40 Gbps connection to the wifi access point.

And is nowhere in any consumer product today. How is it relevant to this discussion?

[–] helenslunch@feddit.nl 1 points 8 months ago

Vision Pro is also not a consumer product today.

WiFi 7 was all over the devices at CES though. It's happening soon.
