P: Support all Windows DPI scaling options (125%, 150%, ...)

Update: As of 10/25/17, we are closing this program to new applicants. We have a large number of participants already. Thank you to everyone who registered!

The Photoshop team has been listening to your many requests for better scaling options on Windows, and we’re happy to announce that we are ready for beta testing on this feature. Because of the large scale changes involved in this feature, we want to make sure people have the opportunity to test it out before it’s released.
 
All Windows customers are welcome to join and test, but please note that you will need to have Windows 10 Creators Edition installed in order to use the new continuously scalable user interface and per-monitor scaling. Windows 7, 8 and prior versions of Windows 10 will only support 100% and 200% - as the continuously scalable user interface requires APIs only available in Creators Edition.

In my case still some of my softwar have not a proper hi-dpi scale: Zbrush 4R7, Photoshop CC 2017,  C4D r16 are still with small letters and butons (but still readebale on my QHD).

Actualy all the software was looking a the right size after parameter de size on windows 10 @17204110% but only some softs like: Corel painter, Groboto or Modzila explorer was real QHD @ 2560x1440 the other first was streched looking fuzzy like my 1920x1080 monitor and i hade to turn on the option "no streching the softwar" of each softwars. I keep a real QHD aspect but with smaler letters...

i found the option for the Hi--dpi monitor in llustrator CC 2015, to put the scale on the closer level that the softwar can manage or in the smaler part or the largest part (no % size only this two option). I get it to the largest option and i think i get a 150% result (not so big, that work with my resolution even the best for me is 125%).

In Photoshop CC 2017 for example i get only two option for hi-dpi monitor: 100% & 200% (2017 bro's).
Why they cant do it for the other resolution ? And actualy why all this "GRAPHIC" design softwar are not able to easely rescale theyr interface for the "GRAPHIC" hi-dpi monitors? I was thinking graphic designers photographer or movie maker or whatever that need to have the best aspect for theyr work was the first public for those kind of monitor so why the softwar dosnt care about it?

 Maybe i miss some information or some parameters in those sofwares but i real didnt found not so many answer about rescaling for hi-dpi option in Zbrush or C4D or toshop as well.
It is realy so complicate for Adobe coders to manage a rescaling UI interface , and for all the other softwar as well ? looking for understending 😉 

Taking the approach that this is Microsoft's problem isn't the right public relations choice. Microsoft has addressed almost all scaling issues in Windows 10 (Redstone). InDesign, Illustrator, Microsoft Office, and Google Chrome are basically perfect now. It sounds to me like Adobe developers need to start openly and realistically discussing Photoshop's technical debt (Bridge & Acrobat as well). 

Still NOTHING? C’mon!

So the new Universal Windows Platform (UWP) apps make use of a fake scaleable "pixel" unit. Goes something along the lines of "effective pixels". At this time, its a system mostly specific to UWP apps, but should this come to support Win32 applications, could it work as a solution for scaling Photoshop?

I know this is a difficult topic but I would really appreciate if this was done soon. I've been struggling for about 6 months with RIDICULOUS scaling which makes me wish I bought a mac.

please update this soon! it would be fantastic!

Well, it seems I struck a chord with my reply, given that Adobe has felt the need to censor it. The reason given was this: "completely off track, with no understanding of the problem whatsoever. Oh, and we're working with the Office team on the issues as well."

I wasn't "completely off track", but merely stating the facts. But since freedom of expression is apparently not supported by Adobe, you can read them yourself on MSDN: https://msdn.microsoft.com/en-us/libr...

And then let's see how long it takes Adobe to censor this comment.

For reference, Adobe - you do NOT censor comments unless they are off-topic, abusive or use bad language. Mine did neither. You censored it because you don't agree with what I say.

And you have STILL not provided any technical details about what is supposed to be so difficult... I am a programmer as well, I'd love to know. If I have "no understanding of the problem whatsoever" - well, that's your own fault, since you don't provide any technical details as to what is broken. Instead you claim that scaling in Windows is broken, when it clearly is not.

I have a suggestion for you: Do a long, detailed blog post on why Photoshop does not respect system DPI settings on Windows. You'd avoid further discussion of this issue by showing that there's a reason for this - and you'd help both yourself and other developers by bringing attention to the issues. Out in the open is always better.

@Jordan: No matter what Adobe will tell you, scaling support in Windows is NOT limited in any way. You simply have to do more work, because Windows supports multiple scaling factors, where OS X/iOS only support 100% and 200%.

Some applications are blurred, because they do not support DPI scaling. Windows will then trick it into rendering at 96 DPI and then bitmap scale the result. The application thus remains perfectly usable, albeit with slightly blurred text. This is the entirely the fault of the developer and not Windows. The alternative would be much, much worse.

To make a DPI aware application on Windows is actually very simple. You simply detect the DPI of the current monitor and multiply all measurements by the resulting scaling factor when drawing your application UI. You then make any bitmap assets in all resolutions (usually 6-8) and choose the right one depending on the DPI of the current monitor. You then tell Windows that your application is DPI-aware. That's really all there is to it. Sure, it takes a lot of work - but there is no shortcut.
If Adobe's in-house UI Framework was properly designed, you should be able to supply an arbitrary scaling factor and have it draw at the correct size.
Adobe blaming Microsoft is simply a lame excuse for not wanting to make the effort to make a proper DPI aware application, instead simply porting over the work done for the Mac.

Adobe - I won't believe a word of your crap, until you give me concrete examples of what is supposed to be broken in Windows DPI scaling and not just some general excuse.
If it is so difficult - why can the Illustrator and InDesign teams make their applications scale properly?

And have a look at Microsoft Office, which is just as complex - and fully DPI aware.

I'd be eager for a 150% and 125% scaling option as well. 200% is unworkable on my laptop, 100% is still rather small (though menus have gotten better). Hopefully this latest creative cloud release redesign was done with scaling in mind.
