Hello,
Just bought a Raspberry Pi, everything went well, except for the screen.
What to do?

Use nano to edit /boot/config.txt remove all of the overscan lines by sticking a # on them to turn the active lines into comments.

Reboot and see if things improve.

The screenshot is of a Mac desktop with a VNC window showing the desktop on the Pi. Changing the overscan settings on the Pi will therefore make no difference to what is displayed to the user in this case.

The desktop that you are seeing is the old version. There was a new version released on Christmas Eve 2014. You can get it by running these commands on your Pi:

Code: Select all

sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install raspberrypi-ui-mods

then rebooting. Once you do that, you may find that the problem disappears. Even if it does not, you may well prefer the new desktop.

How was I supposed to know the OP was using VNC on a Mac from the original post?

With VNC you can change the geometry when starting it. Or edit the perl script and change the default geometry (which is what I did)

Well, it does say 'vncviewer' in the screenshot...

Thanks for the reaction, the screenshot is indeed from the mac but when I connect a monitor directly to the Raspberry Pi the strange screen border is there to be seen too.

I think in some cases VNC will use the default framebuffer size which is controlled by the overscan stuff in /boot/config.txt

With all of that stuff NOOBS adds some very conservative definitions so that most folks get a sensible desktop displayed. The way to tune the settings is remove them all then add back any settings if needed if your display doesn't work.

Code: Select all

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16
# uncomment to force a console size. By default it will be display's size minus
# overscan.
#framebuffer_width=1280
#framebuffer_height=720

The update solved the problem, now I see a normal screen, thanks!

I discovered a while ago that right clicking on an image included in a forum post and selecting "view image" showed the image in its original size. I am so used to doing that that I forgot I had done it. I appreciate not everyone knows about that wee trick.
