New Apple Silicon M4 & M5 HiDPI Limitation on 4K External Displays

A regression in external display support on Apple Silicon M4/M5 generation chips prevents full HiDPI modes on 4K monitors, limiting users to either blurry non-HiDPI or reduced workspace HiDPI.

My current thinking is that in order to make a resolution independent UI toolkit one must first have a resolution independent drawing library?

The things I've found on that were algorithms based on device independent pixels.

Is that still actually the state of the art?

My primary design constraint is that I want the scaling to be zero cost when there's no actual scaling happening.

Can anyone point me to some good books/posts on the subject?

@Eeveecraft @kirb good question.

Granted both #WindowsXP and #Windows7 integrated a lot of #accessibility features from #WindowsMe and #Windows2000 and they inclided high-contrast themes as well.
- But yeah, in terms of #HighContrast & #HiDPI-design, #Windows8 (which @fuchsiii really liked!) certainly does it better woth that full-screen Launcher…

I do think that #FrutigerAero can be made better and more #accessible with a reinterpretation that I'd call "#LexendGlass" because it not using #Frutiger and isn't merely #AeroGlass or #LiquidAss aka. #LiquidGlass, but should use more contrast…

Is it just me, or is Hyprland’s "auto" scaling a bit much?
On my 16" (2560x1600) laptop, Fedora defaults to 1.25, but Hyprland jumps straight to 1.60. It makes my screen feel like a giant tablet.
What scale are you all running for 1600p?
#hyprland #hidpi #linux #linuxlaptop #opensource

1.0 (Native)

100%

1.25 (Balanced)

1.50 or 1.60 (Large)

I just use Auto

Another lightweight post, which got prematurely posted [here], hilariously enough. ;)

How Many Pixels Do You Really Need?

Many notebooks and tablets now ship with displays that aren’t quite HiDPI, but are more pixel dense than traditional displays. In OS 8.1, we now support fractional display scaling in the Secure Session

Just in case you are using an #iPad as your work horse and connect to a computer using a #RemoteDesktop. Here are helpful custom screen #resolutions to make the iPad feel like native.

I am using #SwitchResX. The 21:9 is an ultra wide 4k monitor I sometimes use as external screen, the 13:9 is the new iPad Pro 11", the 10:7 is the older iPad Pro 11". The ultra high resolutions are just there to support #HiDPI resolutions which make the image look crisp!

We have a quick question: how is #HiDPI support in #Tenacity compared to the latest version of #Audacity on #Windows? What about on #Linux?

Just a little curious to see how the state of HiDPI support is between the two right now 👀

Petite découverte du comportement de #macOS …
Quand 2 écrans (1 Retina et 1 non Retina) sont connectés au Mac
Si :
- l'écran Retina est l'écran principal
Alors :
- Le #DPR renvoyé par les 2 écrans est de 2 car l'écran non Retina est forcé en mode #HiDPI

Mais

Si :
- l'écran non #Retina est l'écran principal
Alors :
- Le DPR renvoyé par l'écran non Retina est bien de 1
- Le DPR renvoyé par l'écran Retina est bien de 2

Si j'avais su je n'aurais pas perdu du temps à debug ma page #web pour rien.

On my laptop, I'm using #Gnome 48 in #Debian Trixie, under Wayland. There are two 1080p displays connected, and it also has a 1920p built-in screen which I'm using with 200 % scaling.

If I use Gnome's builtin screenshot tool, all screenshots from the 100 % screens are blurry: It's scaling up the 1080p screens, interpolating pixels.

Here's an example screenshot dragged across both screens, #HiDPI on the left.

The issue is: It's also blurry when screenshotting only a 1080p screen.

Suggestions?
