I've created a diagram to assist those with shieldless 4d systems or to go shieldless for low profile support. Click image for larger version

the Wire used is RGB wire in a loom from arduino to display, connections are obvious, however, you will need to add a 2K resistor between reset of display and ground, so if the arduino loses power and or reset the display doesnt sit there doing nothing, and staying on during that time. the resistor will keep the lcd off (in reset state) until the arduino boots up. Keep in mind in the software since you are shieldless, you need to invert the logic for the Reset as mentioned in these forums. The second USB gives dedicated power to the LCD via another USB port, phone charger, etc. The unit is running stable at 200000 baud on 70dt with about 1 meter of RGB wire. Enjoy
