Subpixel font rendering is critical for readability but, as the author points out, it's a tragedy that we can't get pixel layout specs from the existing display standards.
But the world has increasingly moved to Retina-type displays, and there's very little reason for subpixel rendering there.
Plus it just has so many headaches, like screenshots get tied to one subpixel layout, you can't scale bitmaps, etc.
It was a temporary innovation for the LCD era between CRT and Retina, but at this point it's backwards-looking. There's a good reason Apple removed it from macOS years ago.
macOS looks *awful* on anything that isn't precisely 218ppi. Other than Apple's overpriced profit-machine displays, there are two displays that reach this: LG's Ultrafine 5K, and Dell's 6K (with its ugly, extraneous webcam attached to the top). Other 6K monitors were shown at CES this year but so far, I haven't actually found any for sale. EDIT: Correction, LG apparently doesn't sell the 5K Ultrafine anymore, at least on their website.
That means, the odds are incredibly high that unless you buy the LG, or drop a wad on an overpriced Studio Display or the even worse valued Pro Display, your experience with macOS on an external monitor will be awful.
That's even before we get into the terrible control we have in the OS over connection settings. I shouldn't have to buy BetterDisplay to pick a refresh rate I know my display is capable of on the port it's plugged into.
Computers, on the other hand, have stuck with 1080p, unless you're spending a fortune.
I can only attribute it to penny pinching by the large computer manufacturers, because with the high-res tablets coming to market for Chromebook prices, I doubt they're unable to put a similarly high-res display in a similarly sized laptop without bumping the price up by 500 euros like I've seen them do.
Have you tried adjusting your display gamma for each RGB subchannel? Subpixel antialiasing relies on accurate color space information, even more than other types of anti-aliased rendering.
Not my world. Even the display hooked up to the crispy work MacBook is still 1080p (which looks really funky on macOS for some reason).
Even in tech circles, almost everyone I know still has a 1080p laptop. Maybe some funky 1200p resolution to make the screen a bit bigger, but the world is not as retina as you may think it is.
For some reason, there's actually quite a price jump from 1080p to 4k unless you're buying a television. I know the panels are more expensive, but I doubt the manufacturer is indeed paying twice the price for them.
Still bemoaning the loss of the basically impossible (50"? I can't remember precisely) 4k TV we bought that same year for $800usd when every other 4k model that existed at the time was $3.3k and up.
It's black point was "when rendering a black frame the set 100% appears to be unpowered" and the whitepoint was "congratulations, this is what it looks like to stare into baseball stadium floodlights". We kept it at 10% brightness as a matter of course and still playing arbitrary content obviated the need for any other form of lighting in our living room and dining room combined at night.
It was too pure for this world and got destroyed by one of the kids throwing something about in the living room. :(
It’s an utterly glorious display for programming. I can have 3 full width columns of code side by side. Or 2 columns and a terminal window.
But the pixels are still the “normal” size. Text looks noticeably sharper with sub-pixel rendering. I get that subpixel rendering is complex and difficult to implement correctly, but it’s good tech. It’s still much cheaper to have a low resolution display with subpixel font rendering than render 4x as many pixels. To get the same clean text rendering at this size, I’d need an 8k display. Not only would that cost way more money, but rendering an 8k image would bring just about any computer to its knees.
It’s too early to kill sub pixel font rendering. It’s good. We still need it.
I (on Linux) do not use any sub-pixel AA (just regular AA), but i use aggressive grid-fitting and i have nice, sharp text.
we could do with a better image format for screenshots - something that preserves vectors and text instead of rasterizing. HDR screenshots on Windows are busted for similar reasons.
Unfortunately, EDID isn't always reliable, either: you need to know the screen's orientation as well or rotated screens are going to look awful. You're probably going to need administrator access on computers to even access the hardware to get the necessary data, which can also be a problem for security and ease-of-use reasons.
Plus, some vendors just seem to lie in the EDID. Like with other information tables (ACPI comes to mind), it looks almost like they just copy the config from another product and adjust whatever metadata they remember to update before shipping.
