Hi,
I'm fairly new to this and just after some help. I bought an Arduino Uno and 3.5" display and uploaded the following image with mcfriend_KBV and it all went to plan. I bought another screen and uno from a different supplier and put the exact same sim card with the same image on it with the same sketch and it seems to have a grey background and the colours are different to the original one I bought. here is the link to the first one I bought and the second one I bought in order. Can anyone shed some light on why this may be?
Thanks
Daniel
