Info

Note: the best solution is to disable overscan in display menu options (it may be called "just scan", "screen fit", "HD size", "full pixel", "unscaled", "dot by dot", "native" or "1:1"), then use the disable_overscan=1 option. Edit the configuration file, see the instructions at R-Pi_ConfigurationFile. Add the following lines to the configuration file... If your display has no overscan: disable_overscan=1 or if your display has some overscan: overscan_left=-20 overscan_right=-20 overscan_top=-20 overscan_bottom=-20 Making the R-Pi graphics fill the screen is a matter of experimenting with the numbers you put in the config.txt file. Change the numbers – try jumps of 5 or 10 at a time. Bigger negative numbers reduce the black borders (so -40 means less black border than -20). The numbers do not all have to be the same; you can use this feature to centre the display on the screen. Writing spills off the screen on HD monitors Out of the box, R-Pi graphics may be larger than the 1080p (ie Full HD) screen. This is due to something called "Overscan", and it can be fixed easily by creating a simple text file on the R-Pi SD card by using Notepad on your PC. Follow the instructions in the section "Big black borders around small image on HD monitors", but use positive numbers for the overscan settings, for example overscan_left=20 overscan_right=20 overscan_top=20
overscan_bottom=20 Interference visible on a HDMI or DVI monitor This may be caused by loss of signal on long video cables. The signal level may be increased by changing a configuration parameter. Edit the configuration file, see the instructions at R-Pi_ConfigurationFile. Add the following line to the configuration file config_hdmi_boost=4 You may experiment with different values of config_hdmi_boost. Value 1 is used for very short cables, value 7 is used for very long cables. At your own risk, you can go up to 11, but risk frying a sensitive monitor.
