HDMI to VGA adaptor DOA

by djr255 on Sat Jun 29, 2013 6:21 pm

I have an HDMI to VGA adaptor that will not work on my Raspberry Pi or any other device. The only other forum post I could find on the subject can be found here ( viewtopic.php?f=44&t=41087&p=204719&hilit=hdmi+to+vga&sid=51af3c9b78722ddc4dbb3f84452e2a7d#p204719 ) but so far I have not found a suitable solution. So far I've tried multiple monitors and connected it to an apple tv as well as a Raspberry Pi using the following config file as provided by the manufacturer:

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
disable_overscan=1

overscan_left=-40
overscan_right=-40
overscan_top=-40
overscan_bottom=-40

hdmi_drive=1
hdmi_group=1
hdmi_mode=4

# uncomment to force a console size. By default it will be display's size minus
# overscan.
#framebuffer_width=1280
#framebuffer_height=720

# uncomment if hdmi display is not detected and composite is being output
hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
#hdmi_group=1
#hdmi_mode=1

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
#hdmi_drive=2

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
#config_hdmi_boost=4

# uncomment for composite PAL
#sdtv_mode=2

#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800

# for more options see http://elinux.org/RPi_config.txt

Did you purchase this adapter from Adafruit?

Did you try editing config.txt to set "hdmi_safe=1"?

Please email support@adafruit.com with a link to this thread and ask for a replacement.
