1080 to 800x480

Former Member

Hi everyone.

 

Just got my raspberri pi 3 model b with the 7 in touch display...

 

Im having difficulty setting the lcd to 800x480

Its still set to 1080 for some reason and im not getting full screen...

 

I tried

Sudo nano /boot/config.txt

And i un-hashed disable_overscan=1

 

Still no prevail

 

Besides that i added

lcd_rotate=2

Because the lcd case is upside down...

 

 

How can i set the pi lcd output to 800x480 resolution?

    Hi John,

     

    it is a bit messy because I think that the information on this part of the settings are strictly related to Linux and are not easy to search. I had similar problems in past with a PI2 but I suppose that the information are always the same as this is bare Linux settings (so Debian inherited) and not specially dedicated to the Pi.

    The following link will explain you a lot about this problem and others: RPiconfig - eLinux.org

     

    Instead just to test a shortcut (I have not yet tested on the PI3) you can try to change the following settings:

     

    overscan_left=24
overscan_right=24
Overscan_top=10
Overscan_bottom=24

Framebuffer_width=800
Framebuffer_height=480

Sdtv_mode=2
Sdtv_aspect=2

    What it is important is that you are aware of the meaning of all the parameters that are involved int he screen settings (orientation, overscan, resolution, ramebuffer etc...) Note that the framebuffer w/h should work also for 320x240 screen size.
