I am using Raspbian Jessie, with my Raspberry Pi 2 and a 52" TV. I just updated.

Now, after loading the Pixel my screen size is about 32" and the resolution is lousy. I looked around in the Pixel interface but I cannot find where to adjust the screen size and resolution.

Please assist.

    There's no monitor option under Preferences | Settings? Do you get any output from command tvservice -s

  • It had been removed in updates I guess, I put it back, by editing the menu options. But the max listed display is 640x480. tvservice -s lists the same.

  • Why don't you just run raspi-config and set the default resolution under Advanced/Resolution ?

Edit the settings in /boot/config.txt. See http://elinux.org/RPiconfig#Video for additional information.

    I'm going to give it to you. When I opened /boot/config.txt, in vim and read through it, I noticed, some hidden characters, and thought, hey thats, not right, and removed them. I changed nothing else, rebooted and now it works. Thanks for the heads up for the right file to look at, there was lots of interesting info in that config file.

You can change the display resolution graphically (without using Terminal) on Raspbian GNI/Linux 8 (jessie) using following window.

Application Menu > Preferences > Raspberry Pi Configuration > System > Set Resolution.

  • My version of Raspbian Jessie (8) does not have this option, and the "Underscan" option is now "Overscan" Commented Jan 9, 2018 at 21:51
  • Mine shows nothing under "set resolution" option, just monitor default :-( no matter if Underscan is on/off.
