Screen GUIS position?

So I am having a problem here in my game. I have a frame that holds 3 guis. They are all lined up and put into a frame so i could move them together but the position is wrong. On my screen they fit perfectly and on my brothers screen which is smaller they dont even show up. Keep in mind they are on the left all the way to the end of the screen. I want it to where they show up fine on both screen but yet are still on the far left. IF you could help please let me know how but you dont have to ! :3

My position of the Frame is:

{0, 1420},{0, 0}

Instead of using {0,0}, {0, 0} Try using {0. 0}, {0, 0}

Remember 1 is the max and 0 is the lowest. So I recommend you do like 0.3 or 0.5 etc.
