It is so sad that for us not in the Apple Ecosystem it is impossible to find a desktop HiDPI display. We are stuck in 4k for the past 5 years. This Dell is the only "option", but I don't know how many of us can afford spending $5k on a monitor with a lifetime of ~ 3 years that has not shown great reliability.
Meanwhile, Linux has made the lives of 4k display owners unlivable due to the lack of non-integer scaling. A 5k display with 200% scaling at 27" would help the situation, but we don't have that option.
Many times I have considered jumping on to the MacOS boat, just for the high dpi display availability & scaling support advantage.
There are some very hacky ways that involve special add-on cards for the motherboard, special motherboard model requirements, gpu connector requirements and even special software to adjust the brightness.
It is doable, but it is expensive, and it may or may not work properly. One example that I remember is one where some users who attempted the above setup reported that they need to unplug & re-plug the monitor after it sleeps.
LG does not support non apple software/hardware for that monitor. You can hack your PC with TB cards and special motherboards that support these cards to show signal, sometimes. This is far away from "works fine".
It's still ridiculous. The only people I see using these monitors to their full ability are sitting less than a foot away from the monitor. Even then, kinda overkill.
If you sit really close to your monitor then whatever. Can't imagine it's good for posture or your eyes to be focusing so close so often.
I prefer numbers and measurement units to trademarked, fuzzy descriptions of experiences. Since we're talking about display density, DPI is the term I want to see used.
That's all well and good, you're entitled to your preferences. But it doesn't change the fact that it's not a 'fuzzy' description of experience. DPI alone isn't enough information to describe what it is meant to define.
Again, retina refers to the minimum resolution, at a given viewing distance, where individual pixels are not recognizable.
The part about the viewing distance is essential. As I sit at my desk, my monitor is about a full arms length away from me. When I use my phone, it's distance from my eyes is about 1/3 that of the monitor (ish).
Thus, the DPI required for my phone to have its pixels indistinguishable is a lot higher than what my monitor needs to achieve the same. So in reality, DPI is a fuzzier description of experience than 'retina' is, even if it is an annoying, trademarked, marketing buzzword (which it is, no arguments there).
