I think it would be nice if Epic added a resolution changing blueprint node. Doing it through the console is not good and doesn’t always work properly. Going through the different versions of the engine, I’ve gotten different results with it. With my current setup, using console commands in ver 4.7 resolution can’t be set properly. It’ll always go to 1920x1080 in fullscreen.
Having some obscure .ini file with some settings in it, that’s just not a good way to do things. Something like a resolution pick node from within blueprint should be there. Even listing your rig’s possible resolutions would be a useful thing. So you can simply list valid resolutions using a blueprint setup.
