Yea I got the same problem. I could never clock it to match exact pixels (by adjusting phase/clock) so the texts are always blurred (well, not very but quite). Also when I get the clock/phase pair that I like, if the screen's power is switched off and back on, all settings (clock/phase) will be lost! The fonts are blurred again and sometimes even the entire image goes off the screen.
Another issue is that the "auto-tune" feature on my Lilliput gives different result everytime, sometimes even making the whole image off the screen, not mentioning giving a pixel-clear image.
Anybody have a clue on these?
