OK that's fair since I said "good money" but $10K is a bit out of reach. I was thinking more in the $2K range. My best option today is a MacBook Pro Max with a quad 4K setup, which is relatively affordable but unwieldy and requires at least two Thunderbolt cables (or a desktop setup).

I don't think these are 8K monitors. They support 8K input via 4x 12G SDI, but they contain 4K panels at 3840 x 2160.
