Here's the HiDPI version: http://www.dell.com/en-us/shop/dell-ultrasharp-32-8k-monitor...

It's only $5,000 and probably very few computers can drive it properly.

That one is not wide. For video/music production the wider, the better. For $5k you can have a much better DCI 4k EIZO...

Honest question: why does it matter if you see pixels while producing audio?

I have 3x 4k displays, one of them 30" DCI 4k, one 55" UHD, plus a rMBP and an ultrabook with 3200x1800. I simply can't go back to see pixels again. Once you get used to better, you dislike a downgrade.

I get that, but it's a general point. You specifically called out producing audio, and I was curious if there were specific visual features that are necessary in producing audio. I get it for video editing. I also understand the general "I like high resolution" case.

I am wondering if there is something I am unaware of about the combination of high resolution and audio that made you call that out as a specific use case.

Beside nicer fonts you have "sub-pixel" resolution in e.g. your piano roll/channel list, so you can zoom out a bit more while still able to distinguish stuff there. That is handy if you work with a very large number of channels.

I'm guessing it has to do with how the waveform is rendered. More pixels means a more precise waveform view.
