my resistive touch screen looks like this. Why I am seeing this continuous line of my horizantal sliders. There is no such a problem on vertical one. How can I fix this? Is this about screen? 0693W00000HqbprQAB.jpg0693W00000HqbrYQAR.png0693W00000HqbphQAB.jpg

It's custom board. I just changed LTDC Gpio settings. For my system Display type is RGB565.

Maximum output speed from Low to High and problem is solved.

Hi,

Are you working on a custom board or on a ST development kit ? Is your project based on a TBS available in TouchGFX Designer or did you start from scratch ?

I think your error might actually be due to how the images are stored and transferred, and not the display in itself. Are the assets stored in external flash ? Did you use the correct flash loader when running on target ?

Sure this isn't some signal bleed issue? Or with the power?
