HDMI 7 inch display backpack with touch

by bcain204 on Wed Sep 20, 2017 3:22 pm

Hi,

I recently purchased a 7in touch display and went to hook it up today and am getting lines across the LCD. Further, the touch function seems to be severely off. This is first time this touchscreen has been out of the box and it looks like it is non functional. Any advice or help replacing it is much appreciated it.

Thanks!

That looks like an HDMI resolution mismatch. Did you modify the /boot/config.txt file as shown in the tutorial?
