Is there a config option to enable higher resolution for retina displays?

Hi slaj,

When evaluating priority and time-table of a certain bug or feature request, there are a lot of factors that go into it. Some of them are:

  1. What percentage of users is this likely to affect?
  2. How many man-hours will it take to make this a usable feature/fix?
  3. How many other systems could this break?

With this feature, answers are:

  1. Very low percentage (users with 4k or retina displays only…which is not a lot)
  2. A lot, see next answer for why
  3. Every other tool in editor. Must be tested and debugged across entire engine.

Some of our other considerations can be found here: https://headcrash.industries/stories/why-your-idea-might-not-make-it-into-ue4/

Good points, ; and is perfectly understandable. Needless to say, I am glad that HighDPI support is now being worked on, as it’s made my life so much easier. Epic has also been very gracious to implement other bug fixes for mobile developers that would have been deemed “low priority”, and yet they still did it… and for that I am very grateful. :slight_smile:

BTW, would you be able to direct me to make Launcher point to a HighDPI enabled Editor on Windows? Currently I’m just using a modified shortcut to UE4Editor.exe, which works, but I miss seeing launcher updates, etc. :slight_smile:

Thanks!

Hey Adam,

There is a feature request in for this(UE-28185), but for time being…shortcuts are way to go.

Ah, okay… thanks so much for letting me know!

Have a great day, .

Wow - this is a god-send on macbook… Now to figure out how to make this default in source.

More than 3 years later and same problem. I guess I forget that Epic Games is not as big as other companies like Autodesk or Adobe which already have great high dpi support.

What a disappointment.

Hey Flash7,

Can you make a new thread about small icons? It’d be good to report that as a unique bug as it only appears to be happening in one project.

Today “-enablehighdpi” stopped working. I restarted an editor and everything all of a sudden became very small. I rebooted my PC - no changes, everything is too small. Interesting thing is that project selection window when you start engine is correct (high dpi), but inside editor - all small. Rebooted few times - no changes. Windows scaling settings for UE4Editor.exe are disabled.

I’m not sure why that would be, but you should make sure inside shortcut to UE4Editor.exe flag is still set: “C:\Program Files\Epic Games\UE_4.16\Engine\Binaries\Win64\UE4Editor.exe” -enablehighdpi

And also make sure in compatibility tab that “Disable display scaling on high DPI settings” is NOT selected.

You will likely need to reset flag for each new engine update you do (ie. 4.15 to 4.16), but not for hotfixes (ie. 4.16.0 to 4.16.1). I hope that helps!

Thanks for posting that. Everything’s working fine for me in 4.16.1 with following settings. Are you using a Engine version other than 4.16.1?

Actually, it is funny. I opened another project and it is fine. But scaling has issues only on my main project. Engine 4.16.2

I guess programmers in Epic are still using low res monitors…

Actually, I fixed it by deleting all cached and intermediate files. After that editor started working fine again.
