Hi William,Reflections and missing impedance matching will most likely be the cause.
The level converters of the shield have no resistors on the outputs, and the TFT none on the inputs to dampen reflections.Extending the write strobe length may be enough to get it working.
Do you use MCUFRIEND_kbv?

Thank you for the response, Jean-Marc. I do not use MCUFRIEND_kbv, I'm not sure if that library works with my TFT. The libraries I am using are called UTFT and URTouch.
What do you mean by "wire strobe length"?
William
