Troubleshooting: Create own config.txt
(for custom resolution)
Create your own config.txt file, put it to the internal storage and click ‘boot.conf’ custom to copy it to the bootload-
er. Reboot the system to make changes to take effect.
The standard config.txt looks like:
hdmi_force_hotplug=1
gpu_mem=256
If you use a HDMI to VGA Adaptor, for a resolution of 800x600, write:
hdmi_group=2
hdmi_mode=9
hdmi_drive=2
hdmi_ignore_edid=0xa5000080
hdmi_force_hotplug=1
gpu_mem=256
If you use a HDMI to VGA Adaptor, for a resolution of 1024x768, write:
hdmi_group=2
hdmi_mode=16
hdmi_drive=2
hdmi_ignore_edid=0xa5000080
hdmi_force_hotplug=1
gpu_mem=256
If you need a stronger signal, you can additional write this to the file (range from 0 -7):
config_hdmi_boost=7
hdmi_drive chooses between HDMI and DVI modes:
hdmi_drive=1 Normal DVI mode (No sound)
hdmi_drive=2 Normal HDMI mode (Sound will be sent if supported and enabled)
Display Modes:
You can ignore the screens edid: hdmi_ignore_edid=0xa5000080
edid is a code which the screen sends to the PocketVJ to tell which resolution he prefers
hdmi_group defines the HDMI type:
Not specifying the group, or setting to 0 will use the preferred group reported by the edid.
hdmi_group=1 CEA [is used for TV Screens]
hdmi_group=2 DMT [is used for Computer Screens]
hdmi_mode= defines screen resolution in CEA or DMT format: (see next page)
