## Wrong colors
## Wrong colors or graphical corruption
Some screens will not behave correctly and display wrong colors,
Some screens will not behave correctly and/or display wrong colors,
this usually due to the wrong [SPI](https://en.wikipedia.org/wiki/Serial_Peripheral_Interface) speed
In my case I had to use 16 Mhz (default is 24Mhz)
In my case the maximum i could achieve is 22.22Mhz (400mhz core / 18)
```
dtoverlay=piscreen,drm,speed=16000000
dtoverlay=piscreen,drm,speed=22222222
```
As you may predict speed has a big impact in usability as it dictates how often the display will refresh
reboot to test any changes.
## Rotation
!!! bug
The current Rpi Kernel v6.1.77 has a bug in the dtb and rotate doesn't work, fix has been merged in v6.6
you can copy the dtb from the new kernel into the old one if needed
You can rotate the screen adding a rotate line with the degrees [0, 90, 180, 270]
```
dtoverlay=piscreen,drm,speed=16000000,rotate=180
dtoverlay=piscreen,drm,rotate=180
```
Screen rotation will require adjusting the touch matrix see [Touch issues](../../Troubleshooting/Touch_issues/)

```
fbcon=map:11
```
!!! warning Important
do not add newlines to the file, it must be 1 line with the options separated by spaces
