I wasn't sure how you plugged the display straight into the GPIO header, my display has GND, VCC, SCL and SDA in that order.I just hooked up GND, 3.3V, SDA and SCL with jumpers to the relevant pins.
Looking at the schematic, you NEED a resistor, tho one onboard is only connected to the onboard LED.
