Yes I have! I tried almost all of the attached libraries/sketch..
And those are? And forget UFTF, unless you modify the library yourself.
I also tried the code snippet from misc.ws and my display says "Unknown driver chip 7783".
Thats what the controller is, as mentioned on post #11. I dont know why the chinese guys keep mentioning the other controller... But for the price is the best display you'll get your hands on, so worth the hassle.
Maybe my TFT is damaged, it shows banding (lots of, not very visible in attached images).. 
Seems very heathy to me. One of the initialization commands is wrong tough. I find it hard that the libraries for the ST778x are not working. Try the link on post #13 and report. What IDE version are you using?
Did you install the "ADAFRUIT_GFX" library?
