Showing the Raspberry Pis behind glass is only to gloat: "We got Raspberry Pi 4's, and you don't".

If I was there in person. they would make me choose another restaurant.

The Raspberry Pi 4 introduced dual micro HDMI ports, each capable of outputting a 4K30 signal.

I'm pretty sure a recent driver update managed to squeeze out dual 4k60, but I'm not sure what sorts of tradeoffs might come from using it.

If I could get one Pi 4, I'd be happy, let alone six.

*at a reasonable price

When did that happen? My impressions is it’s still 4k60 over one HDMI. If I have to guess the trade off is dropping support for some legacy HDMI features

I don't know if it's single or dual 4k60, but this is probably what I read:

Linux 6.2 To Put The Raspberry Pi In Good Shape For 4K @ 60Hz Displays - Phoronix

I just updated my Pi, to see what the current kernel is. The last time I updated it was a couple months ago. It jumped from 5.15.84 to 6.1.21! I wouldn't hazard a guess about when they'll take the >= 6.2 kernel, but it might not be that long. Otherwise, you'll have to manually find and install (or build your own) kernel to get those patches.
