I tried the other screen i bought and it looks a little better in my opinion. The 5" screen has a really terrible viewing angle compared to the 4,3" screen.
When looking at the 5" screen at an angle, the screen starts to turn white which is really annoying.
This is the reason why i almost always buy two of everything, so that i can test and choose which one works best for me.

I also installed the amplifier i bought, it's very small so i just hot-glued it to the side of the left battery.

The wire bundle at the bottom will be removed as soon as i'm 100% sure all the GPIO are connected correctly and everything works.
