Screen resolution resizing – Natron
The viewer will show whatever resolution (format) it is fed. In this case you are feeding it a resolution of 500×445. If you want it to be 1920×1080 You’ll need to ensure that your solid node is outputting that format. Looking at your comp, that solid node is probably the background and so it should be set to the “project format” option. To set the project format press S to bring up the project settings and set the project format to 1920×1080 (which should also be the default).
Hopefully this gives you the information you need!
