If you could just copy the code and change them yourself it might be easier than explaining! Thank you

The second shows the same thing without the white thing in the corner. Yes you have the correct dimensions and i believe 0,0 is top left corner!

This is what this code is doing, it isn't with the modifications you have showed me, i will send that later on. I want these bars wider but i want to make it cover the full screen. I can change the var rgb = new Uint8Array(50*3); 3 to 9 and it make full screen but i dont know if that will change my leds.

In post #16 it didn't widen the bars though it, it moved them over the the left or only showed one bar!

The emulators are great but it still doesn't help me with what i need to edit, I'm on here for help because I'm not sure what i need to change that doesn't tell me what i need to change or anything, I understand how the first guy helped me but you completely changed what he did.

You made this so much more than it needed to be, I have no idea on any of this stuff you're talking about and wanting me to do now. I just wanted the simple fix to enlarge my screen thats it.
