I’m having some issues with the scaling of the interface in the Unreal Engine Editor when using my dual monitor setup.
My main monitor has a resolution of 4k (3840x2160), while the secondary monitor has only the resolution of full HD (1920x1080). It seems that the interface scales to fit my full HD monitor, meaning that the interface on my 4k monitor is super tiny. I am aware that I can scale the interface with the Widget Reflector but that is not really any ideal solution since it does not scale every element in the interface, especially the menus and submenus.
Example: (Left side is prior to scaling with the Widget Reflector.)
As you might imagine this can be quite difficult for someone who has fairly recently started developing in Unreal Engine. I might add that when I started using version 13.1 it was completely fine, it scaled to my 4k monitor automatically, but then one time I restart the engine and it changed for some odd reason.
There is also one other issue by scaling with the Widget Reflector in the blueprints. Whenever I drag a line from for example an output, the line is very much offset from the mouse location. Take a look at the example bellow to see what I’m talking about. This isn’t a major issue, but it can be a bit annoying.
If you have a Nvidia card, you can turn on DSR and then scale your 1920 x 1080 monitor to use a higher resolution that matches your 4k monitor. I do that here at work for one of my monitors and it works out pretty well.
I’ve now tried what you suggested but unfortunately it doesn’t seem to have any effect on the interface scale. I also tried to restart my computer after I turned on DSR. After that, i tried to unplug the second monitor, but nothing seems to work. I’m guessing there is some sort of setting in the engine I’ve accidently changed somehow. I guess I could try to reinstall the engine version but I don’t think that’s a good long term solution since this issue popped up after just some days of using the current version. (I also had the same issue in 4.12).
However, initially it scaled fine even in 4.13. I am still hunting the issues and as I mentioned in that thread I don’t know if taking screenshots really means anything because I can’t take a screenshot of what it looked like before it started doing this for comparison. I have uninstalled and reinstalled the editor and that doesn’t seem to solve the issue.I don’t have another PC to test multi monitors on to try and reproduce it either. It is also the editor as it effects ALL projects loaded into it. Interestingly enough it doesn’t effect the launcher…so maybe if I take a picture of the editor in comparison to the launcher that might help?
It also asks if i made changes to widget reflector but I don’t see how that matters as it does not save settings. I have also noticed that according to the unreal roadmap this feature is listed as incomplete. Trello
OK so from what I can tell the Unreal Engine editor is just not a DPI aware program now. Will not let you change its DPI scaling using any windows settings. This is a problem. I know me and Renddigital can’t be the only users working with large high definition monitors. More and more this is becoming the norm and more and more I am finding applications that are not taking this into account.
