Hi,
I'm sure this is a stupid question, but, is it possible to use a Mega TFT screen/shield on a Due. This is the screen that I have which I have working with a mega but it is a bit slow. I was loaned a Due for another project and am trying to resist temptation to use it on it.
Any advice would be appreciated.

As long as you have DUE driver and can wire it.... should be able to. I have just recently wired a mega2650 SSD1289 shield to a DUE and get blazing speed. (~200 320*240 screen clears a second).
First, get it going on the Mega as intended... verify it works etc.
Then... wire it to the Mega as the pins will be 1:1 and in the same position. What you want to do is find out exactly what pins are needed.
For mine all I needed for the TFT was the 16 data lines, 4 control lines and gnd/vcc.
The port mapping on the DUE is different so if you have a 8 or 16 bit interface you need to make sure the pins for db0-7/db8-15 on your TFT match with the DUE ports.
Matching the 16 data lines on mine was a nightmare because of the horrible sequences.
Also... DUE is 3.3V and Mega is 5v... make sure the TFT is 3.3/5v compatible or like mine with a 3v3/5v switch.
Forget Hoek's advice........... Use UTFT libraries....... by Henning Karlsen.......... and the appropriate shield for whatever Arduino you are using......... everything works fine!!!
