Hey! No problem, as long as I can help easily I would do it!
I am using Wondershare Filmora to record my videos. The games are played on one moniter that is set to 1440 : 900, and I think it is related to the resolution because I noticed once uploaded to YouTube they are not on full screen (there is a little of black sceen in both sides, left and right) unlike when I was recording in older Laptop that has 1366 : 768. It might be the resolution of 1440 : 900.
Hope this helps out!
