I'm assuming sarcasm here, but just to be clear:
There's almost no (no?) end-user hardware to display 8k.
A 8K desktop monitor would be superfluous because 5K is already too dense for eyes to resolve individual pixels on a 27" display, about the largest desirable desktop monitor size.
Someone close to me has an 8K RED and we both know it's primarily useful as an interstitial format in media production or for commercial projection, but I don't see how it's that valuable as a resolution for consumer hardware. There aren't even any standard cable protocols for 8k signals that I know of: DisplayPort 1.3 can't even handle 5k@60Hz@30bpp in one stream and DP 1.4 doesn't boost the max bandwidth per stream.
...not really, I have the 4k Ultrafine and I can see dead/hot/stuck pixels sitting at about 3.5' away. Anyhow, always someone to defend other's logic lol. Speak for yourself. Another pitfall of the ultra fines is the uneven backlighting/hues/colors on white background while using productivity software, reading articles, etc.
