Yes this. I don't use screens below 200dpi anymore (right now I have 4K on 24", at 200% scaling) and many people say that it's a waste because it's way too high. But I can still see pixels that are off. I just love sharp text. Which everyone is used to on their phones, I don't understand why people don't want the same on their computer which they probably use a lot more hours per day (I sure do)
I'm sure I would notice and be annoyed by this fringing too unless the pixels were so small I really couldn't see them. Probably needs to be slightly higher than 200 then. But I haven't seen oled monitors with such high DPIs. The highest I've seen is 4K on 27" which wouldn't even do for me on LCD.
I have Dell P2415Q, from 2015. There are, like, 4 other (legacy) models of 24" 4K out there, and that's it. I've no idea why they don't manufacture them.
I also have one bought used. It’s the only way to have 4k and 200% scaling on Linux without everything being too big or too small. Size and ppi are perfect but sadly other aspects are becoming really dated (bad colors and contrast, high latency, low refresh rate etc).
I also have one, and it's holding up pretty well. A month or so ago I broke out my colorimeter and it had almost 100% sRGB at around 120 cd/m2. I don't recall the delta E, but it was very low.
While I didn't measure the backlight, it does seem to not go as bright as before, judging by the levels I set in the OSD. I never went above 70% or so when the sun was shining in the room (not directly on the screen, though), so it didn't have any effect on me.
I understand there are two version, I have the second one. But I don't think there's a difference in the panel itself, I think the change was related to HDMI support.
I can't comment on the latency, the only games I played on it were Civilization and Anno Something. Never had a problem for this.
I have been using P2415Qs for over 10 years by now. Replaced some, bought second hand, had to ship to Dell at one point because of the wake issues (pointless: they never really fixed them), so I know the drill. There are actually 4 versions.
The last new one I bought in 2018 I actually paid the same price for it than when I bought my first one in 2015, so it is one of those few computer accessories that significantly increased in price over its course rather than decrease.
If you cannot see the P2415Q degrading and/or being generally crap in any metric (EXCEPT DPI) when compared to even the non-IPS black Dell monitors from this decade, you are simply blind. They are early HiDPI-revival-era panels, and it shows.
Some of the newer IPS black panels are so good that it is tempting to just take the DPI hit and go 27''... albeit with care as it seems Dell has decided this last year to put some filter that further increases blurriness.
I don't pretend that I have the best vision out there, though I don't think I'm completely blind since I don't run into things. But I actually measured this display, and it's within specs. So maybe both I and my colorimeter are blind? Sure, it's not absolutely impossible, but how likely is it?
I actually have a newer "ips black" dell, an ultrasharp 3223qe and yes, it's much better.
But what I'm saying is that the old one is still good. However, I never pretended it was as good as current models. That's moving goalposts. The initial comment was about the display degrading, so comparing it to itself when new (not even other similar models from that era!). Mine only seems to have become somewhat dimmer, but not enough to matter in my day-to-day use since it's still brighter than I need.
I have the same Dell (since 2016) and love it. But eventually I transitioned last year to a 27" 4K monitor. Still almost as sharp (KDE at 175% works fine for me).
yeah, I've tried their 24" 4k monitor, was okay, but not great, so returned.
24" is the max size I can tolerate with short-sightedness, but avoid using glasses for the monitor.
Just a nitpick… it's ppi (pixels per inch). dpi is unit used in printing.
I have the same monitor and i believe over 200ppi is pointless for desk monitor unless you are very close to it. It makes sense for laptops which you have much closer but i think most people have desk monitors way way further from the eyes.
I have a dual 4k/1080p(480hz) oled monitor at home I mostly run at 1080p and 4k lcd monitors at work. I bounce between both and really don't notice much difference. I need the text zoomed on 4k anyway, so it is effectively 1080p screen area, but sharper. Growing up in Atari days I don't mind pixels and actually like them. Latency and the 480hz is more important to me than 4k pixels.
I grew up in the Atari days too but I really need the HiDPI. I run at 200% scaling too, so effectively also 1080p. But I really love not or almost not being able to see pixels.
I'm sure I would notice and be annoyed by this fringing too unless the pixels were so small I really couldn't see them. Probably needs to be slightly higher than 200 then. But I haven't seen oled monitors with such high DPIs. The highest I've seen is 4K on 27" which wouldn't even do for me on LCD.
