I recently purchased a 2.8 inch tft display screen for my arduino projects.
When using the graphicstest file in the examples and uploading it onto my arduino uno, I was met with a surprise. :-\
There was a multi-colored grey and pink screen taking up 75% of the display, it sort of looked like a tv grain. Whatever came in contact with it (like the duplicating lines from the example) would duplicate there and stay there even after a reset until the usb cable was unplugged from the computer.
I don't know what to do, any suggestions?
