我搜索了下，有好多人遇到跟我一样的问题，但都没有很好解决，现在是4.13版本了，对HTML5的分辨率还是只能维持800x600吗
I search the next, a lot of people encountered the same problem with me, but they are not well resolved, it is now 4.13 version .and the resolution of HTML5 or 800x600 can I change it?
the default resolution is 800x600 and is configurable in
DefaultEngine.ini
[SystemSettings]
r.setRes=WidthxHeight
hope that helps!
