Hi stm,

​We are working with 240x320 resolution display by the following configuration

1 display support 18 bit so we configured DSI with 18 bit and ltdc format with 24 bit and dma2d with rgb888 and changed configuration to 240x320.

2. display runs in command mode single data lane with hsyn, vsynch as 2, hbp, vbp as 2 and hfp, vfp as 2

3. DSI bandwidth with 500 mbps, 62.5 byte tx. and ltdc clock with 41.7 Mhz.

My problem is display is able to show text as well as images, please find attached picture. Issue is extra line drawn at boundary of some image​s while other images are properly potraited.

I have done following changes.

​1. Changed sync, bp, fp to less and high but display is not showing exactly with in 240x 320 slant mode.

2 set pitch is 800 but if I changed to 240 as width, display is potraited with multiple images.

what shall be issue​ ??

Regards,

Kishore​
