HDMI Overscan / Underscan - Dygaer - 04-28-2016 Currently the screen clips off edges of the console. Is there a way that I can change the over scan setting in the /boot/uEnv.txt file? The Raspberry Pi has something like this with their /boot/config.txt file using the following settings. These are the one's that I would be interested in using with the uEnv.txt file. DISABLE_OVERSCAN Set to 1 to disable overscan. OVERSCAN_LEFT Specifies the number of pixels to skip on the left edge of the screen. Increase this value if the text flows off the left edge of the screen; decrease it if there's a black border between the left edge of the screen and the text. OVERSCAN_RIGHT Specifies the number of pixels to skip on the right edge of the screen. OVERSCAN_TOP Specifies the number of pixels to skip on the top edge of the screen. OVERSCAN_BOTTOM Specifies the number of pixels to skip on the bottom edge of the screen. FRAMEBUFFER_WIDTH Specifies the console framebuffer width in pixels. The default is the display width minus the total horizontal overscan. RE: HDMI Overscan / Underscan - dhardingham - 04-28-2016 It is also possible to change the overscan settings on-the-fly when using a Raspberry PI. There is a small C program that writes directly to the VideoCore GPU, to control the overscan settings - https://github.com/ukscone/set_overscan This is what we need for the PINE64.
