Hey everyone. I've been after this for a while now but have yet to resolve this problem:
I purchased a 3.2" tft lcd shield + touch panel TF Reader for arduino that claims that it works with the Arduino UNO (even shows it being attached to an Arduino Uno in the product image). I have no idea what the name of the shield is since it doens't mention it on the shield or in the description for the item but it does say that it uses SSD1289 controller and links to that same website (but a different code [other than UTFT]?? check out the "downloads" on that ebay listing).
Link to the item (hopefully it will stick around for a while): http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=270972145966&fromMakeTrack=true#ht_2045wt_699
I've attached it to my Arduino UNO and am using code and libraries from the link below (standard UTFT). The display resolution on the LCD monitor is 320240 pixels so naturally I tried the __UTFT example meant for 320240.__ I've modified the code for my display (as far as I know) but all I get is a white, randomly flickering screen (doesn't always flicker). In the code, I inserted SSD1289 for the controller (search for "DotScott" on this page to see my notes in the code).

Am I missing something somewhere? Is anyone else out there having this problem?
