Everyone,
We need an HDMI monitor for a permanent connection to the Pi that powers our tablet content.
Ideally it should be smaller than 19" (so it can fit on a rack shelf) but not less than, say, 15" (so we can actually read it).
I tried using a known-working HDMI-VGA adapter. But it's not supported by the Pi.
Does anyone have a suitable screen to donate, or can someone buy it for us?
This is something we need quickly.
so you get the "Input not supported" box i do the same thing here, but I had no prob, i slap this on most any generic vga monitor. your monitor just might not handle every video mode that's all but also some of those converters only handle a limited selection of video mode resolutions so you need to check the specs on both, the monitor and the converter wasn't there someone there who can help configure the RPi, then you can try alternate settings I use the same generic option below, that's probably what you have now, hdmi_safe=1 hdmi_group=1 hdmi_mode=1 then you can try alternate options, hdmi_group=2 hdmi_mode=8 hdmi_ignore_edid=0xa5000080 config_hdmi_boost=4 disable_overscan=1 and then here's some of the sites to provide the explanation of the various settings, http://elinux.org/RPiconfig#Video_mode_options http://elinux.org/R-Pi_Troubleshooting#No_HDMI_output_at_all http://elinux.org/R-Pi_Troubleshooting#HDMI_-.3E_VGA_adapters and this is available from RPI support, compare this to the model# for your monitor, and the specs of that converter HDMI-VGA conversion may post compatibility problems under the following conditions * The HDMI source has different refresh rate than the VGA display * The VGA display (projector, monitor or TV) does NOT support the resolutions as output from the HDMI source (480i, 480p, 576i, 576p, 800x600, 720i, 720p, 1280x1024, 1600x1200, 1080i, 1080p) * The VGA display does NOT support interlaced resolution while the HDMI source is set to 1080i, 720i, 576i or 480i * The HDMI output of source device does NOT supply 5V/500mA power fyi, did you borrow that, not sure which model you have there, cause you can just buy the same inexpensive, and versatile one that I use here -- only $6/prime but first tinker with the settings http://tinyurl.com/y9asmu84 google foo = 10min Dan -- _ ____ / \__/ Scotty, We Need More Power !! \_/ _\__ Aye, Cap'n, but we've only got 80 col's !!
