I bought a 3.5" LED screen that is on my Pi, however it is nearly impossible to use because edges of windows are clipped off etc.

How can I 'zoom out' so that all the windows are really tiny? Basically so I can fit the entire display on the screen.

Thanks

Use XRandR panning.

First , determine the display names.

xrandr -q

Then setup the panning itself :

xrandr --output DISPLAYNAME --mode 640x480 --panning 1920x1080

Use this to restore the normal mode :

xrandr -s 1920x1080

overscan would most likely fix this issue. See this post, and the official docs. Basically, overscan fine tunes the image size. You can change the overscan with sudo raspi-config or you can change the overscan more precisely by editing /boot/config.txt but you shouldn't need to. But if you need to edit /boot/config.txt, check the official docs for config.txt. You would want to add/edit the parameters overscan_left=, overscan_right=, overscan_top=, overscan_bottom= and set them equal to something bigger, just mess with the number and see what works best.

    I don't think overscanning is the issue. I think the screen is simply too small to show the windows in their entirety. – Jacobm001 Feb 29 '16 at 0:05
  • @Jacobm001 oh, my understanding was that the display was not fitting properly, I see what you're saying now after rereading the question. – Patrick Cook Feb 29 '16 at 0:08
  • So how can I shrink the windows? – Maffs Mar 1 '16 at 9:13

startx -- -dpi xx Try different xx settings for your display

    Why is there a blank -- in your command? What does -dpi xx do? Someone who isn't familiar with this command may not understand what values of xx to try, or how they relate to the output. – Jacobm001 Apr 29 '16 at 15:05
  • The OP was having trouble with the GUI and therefore he uses this command. The double dash is used to say the following commands are driver commands. – PaulF8080 Apr 29 '16 at 16:38

    My point is that such information would be good to include in the answer. – Jacobm001 Apr 29 '16 at 16:39
  • I intentionally don't explain the full details. I have found that you learn more and remember more if you look things up yourself. – PaulF8080 Apr 29 '16 at 16:47
