Screens that use HDMI should work out of the box

you may need to configure the resolution in RaspberryOS Bookworm
you can do this by editing the kernel commandline

```
sudo nano /boot/firmware/cmdline.txt
```

!!! warning "Important"
    Do not add newlines to the file, it must be 1 line with the options separated by spaces

for example:
```
video=1920x1080
```

more complex example:
```
video=HDMI-A-1:1920x1080M@60,rotate=90,reflect_x
```
