One user found that his DVI-D monitor blanked out when +5V was too low. Which resolved an issue with DVI monitor reporting “input signal out of range”Īs a last resort, try deleting (rename to keep backup) config.txt from the SD card.Īlso check that the RasPi +5V voltage (measured from TP1 to TP2) is in the correct range. You can override this with: hdmi_force_hotplug=1Īlso try the following video options: hdmi_group=2 Your monitor/cable may not be asserting the hotplug signal. Otherwise, try adding the following line to the configuration file (similar to interference case above) config_hdmi_boost=4 If you have the Wheezy image (recommended) then try hdmi_safe=1 No HDMI output at allįirst make sure the display is powered on and switched to the right input before booting Pi. This symptom can also be caused by RasPi +5V (measured from TP1 to TP2) falling too low. This option can also help when there is no display output at all, the display periodically blanks, or colours are wrong/inverted.

Value 1 is used for very short cables, value 7 is used for very long cables. You may experiment with different values of config_hdmi_boost. The signal level may be increased by changing a configuration parameter.Īdd the following line to the configuration file config_hdmi_boost=4 This may be caused by loss of signal on long video cables. Overscan_bottom=20 Interference visible on a HDMI or DVI monitor 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.įollow 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

Out of the box, R-Pi graphics may be larger than the 1080p (ie Full HD) screen. Writing spills off the screen on HD monitors The numbers do not all have to be the same you can use this feature to centre the display on the screen. Bigger negative numbers reduce the black borders (so -40 means less black border than -20). Change the numbers – try jumps of 5 or 10 at a time. Making the R-Pi graphics fill the screen is a matter of experimenting with the numbers you put in the config.txt file. Or if your display has some overscan: overscan_left=-20 If your display has no overscan: disable_overscan=1 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.Įdit the configuration file, see the instructions at R-Pi_ConfigurationFile.Īdd the following lines to the configuration file… This is due to something called “Underscan”, and it can be fixed easily. Out of the box, R-Pi graphics don’t necessarily fill the whole screen. Creating a suitable cmdline.txt fixes it – type the following at the Raspberry Pi command line: sudo echo 'dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 root=/dev/mmcblk0p2 rootfstype=ext3 rootwait' >/boot/cmdline.txt Big black borders around small image on HD monitors Known issue with distro package as of 17th April 2012 – there’s some missing boot config information. Can only get 800×480 resolution in LXDE (Arch linux) Additional codecs were not purchased as licensing fees would have increased the R-Pi’s price. H264 is the only hardware-accelerated codec, for playback. The only hardware-accelerated video player is in the XBMC distribution and its command line variant omxplayer. Temporarily renaming, moving, or deleting that file may fix the problem. Xauthority file in your home directory, causing startx to fail, according to this thread.
