It’s been slim picking for 5K monitors- especially if you’re not on OSX where thunderbolt dispay output is much more complicated.

Besides the (now discontinued) Planar IX2790, which had severe quality control issues (went through 4- all with major dead pixels and burn-in), I don’t think there are any readily available DisplayPort-based 5K monitors out there :(

Feels like hidpi displays have pretty much stagnated outside of apple ecosystem

Yeah. I don't like to use 4K monitors with 15" Macbook Pro, because the latter has 16:10 screen (with emulated 1920x1200 resolution, with 2.25 real pixels for every emulated pixel), while typical 4K monitor has 16:9 aspect ratio with 1920x1080 emulated resolution (4 real pixels for every emulated pixel), so you'll actually loose vertical desktop estate, unless you run it in non-high-dpi mode which looks just ugly.

Well 8k is the new hotness. There is the dell UP3218K for example.

That said, 4k @ 27" vs 5k @ 27" is a bit of diminishing returns, and its hard to justify the price, when instead of a single 5k, one can get two 4k.

Why is it 8k and not 16k? I thought it was proportional to the logarithm of the number of pixels.

We went from 1920 wide to 3840 to 7680.

A step of 4x give or take in number of total pixels each time.

It’s a logical progression?

But either way, 8K is already pushing the limits of what today’s video transports can carry. 16K is currently impossible.

Uncompressed 8K/60Hz requires >64% of the max BW of DisplayPort 2.0 (which is not even on the market yet.) That’s why he needed 2 DP cables.

I believe it's the result of the semi-random crystallization of the effective consensus about what word to use. Partly also what feels like "the next one after".

The returns are diminishing, but if your eyesight is good a 5K monitor is much nicer to work with. Ultimately the reason 4K took hold was part marketing and part display interconnection/GPU technology. The Mac was pretty much alone in driving 5K adoption.

The UP3218K was released in 2018 and pretty much stands alone in that space, for the same reasons.

It’s not only about pixel density, although that’s important. Most importantly, 5k gives you integer scaling for a resolution of 2560 × 1440, which is perfect for 27 inch. If you can get similar results with another setup I would love to hear about it.

This and exactly this! I’d love to get one 27 inch 5K monitor for my work(looking at code and text) and have integer scaled MacBook Pro resolution. That would be perfect. But, it’s silly that there are zero choices in EU at the moment. The LG ultra fine is taken out of stock due to some EU regulations, and there is nothing else :-(

"The LG ultra fine is taken out of stock due to some EU regulations"

Is that true?

I bought one about two weeks ago from Saturn, for 19% off. Still waiting for the delivery though. According to "geizhals.de" there are a few stores that still have it in stock.

Yes, I’d love to buy one, but can’t here in Denmark.

The wholesale vendor for DK says there is some contention with EU regulations that prompted them to hold on all orders :-( he does not know which regulations they are.

Does integer scaling matter for text or images? Or is it just for UI elements drawn on a pixel grid?

I don't know how text is implemented, but based on my experience, it matters. On my 13inch MBP screen text and everything else is incredibly sharp. I hope someone more knowledgeable can chime in.

It matters for everything on macOS, which achieves non-integer scaling by rendering to a larger frame buffer then scaling down the entire image to the panel resolution.

MacBooks for the last few years have shipped with a scaled mode enabled by default to give more screen space, I always bump it back down because I hate how fuzzy it makes everything look.

It doesn't matter on Windows.

I've been very happy with a '5k2k' monitor, I have the MSI Prestige PS341WU. The resolution is 5120 x 2160 at 21:9, and it's basically a stretched-out 27" 4k monitor, so same height and vertical resolution, just wider.

Gives enough real estate to have three 'panels' of windows, and it's all one monitor: I find that two-monitor setups mean I have to either always tilt my neck left and right, or set up one centrally and then really kink to the side to view the other one.

Everything is the wrong size at 4K @ 27” though (on macOS at least).

Either you run at 1x scaling and everything is tiny, 2x scaling and everything is comically huge, or a non-integer scale and everything is fuzzy.

4k @ 28, I used to run 1.5x but eventually switched to 2x because I did want kinda larger stuff due to myopia.. actually it's not that comical once you get used to it.
