GT911 - 40 points Offset on X asix

Goodmorning,

I'm using an 5" display (X= 480, Y = 272 ) with GT911 on board. The PID version is 0x1060.

I have a problem because X asix has always a 40 points of offset.

If I swap both asix ( X -> Y) the problem on X disappeare, but it appearson Y asix.

For solve this problem, I must fake the X dimension to 520 points when I transfer the new configuration to GT911. What's The result? I removed Offset on X, but sometimes it read wrong data.

Is it possibile to have a more detailed datasheet to understand how all parameter works?

I.E. = how does Stretch_R0 , Stretch_R1 , Stretch_R2 , Stretch_RM works? Are they involved with space (top/bottom/left/right) parameters? There are some parameter that manage the Axis offset?

If someboy want/can help me, plese write to me at: pastrellomarco@virgilio.it

Thanks a lot

Best regards
