so ive been using spi screens and now prefer them to tft however i need to make my screen smaller to fit better within my gameboy pocket screen.
ive used overscan before , edit the config text removing # but it doesnt matter if i put in a positive number or negative neither seem to adjust?
i think in the original setup of the screen using moosepr guide i have to disable overscan, so does this mean it can not be adjusted?
any tips would be great.

Re: overscan on an spi screen
There is a line that needs to be uncommented to enable overscan. Right above the left, right, top, bottom.
And you have to reboot after each change to see the difference.

Re: overscan on an spi screen
i've personally not used any overscan settings on a build before that uses a SPI screen....
however, i will be at some point...
so have just quickly tried to adjust them....
(this might be of help to you)
before any settings have been applied....
applied these settings (maybe a little extreme)....
after a reboot, this is what i got....
may help....
you might need to start a fresh (new .img) if nothing changes ....
a little tip....
what i've done is build a fresh .img of Retropie...
which has the fbtft script installed along with Retrogame and my WiFi settings (and the odd game)...
and done a backup of it...
this way if i encounter any errors, its just a case of formatting the SD Card and reinstalling the .img without redoing everything...
(if doing this, its recommended to do it on a low capacity SD card, you can get away with a 4GB)
plus it saves time when starting a new build/project....

Re: overscan on an spi screen
For the pocket, this is my config.txt
Code: Select all
# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
disable_overscan=0
overscan_scale=1
# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
overscan_left=15
overscan_right=-30
overscan_top=-30
overscan_bottom=-30

I had good results with this:
https://github.com/ukscone/set_overscan
Let's you update the overscan with real-time feedback. Only works if overscan setting actually are working though.
