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
Errrr most of that is gibberish to me.
well, get some who doesn't think it's gibberish, where's your tech help over there, the one who set up the RPI this isn't windows plug 'n play crap
I have a generic HDMI-VGA adapter. It works fine, such as when I connect it from my Chromebook HDMI out to a ordinary LCD monitor or projector.
ok cool,' then most likely the monitor is lacking some video modes, obviously the generic settings, which is the highest video mode, so you just have to use a lower video mode that's what the "gibberish" is for either learn it or get someone
All I did today was plug the HDMI end into the Pi and the VGA end into a 10-year-old 15" VGA LCD. No big fancy test.
ok like I mentioned , it's might be lacking some video modes like 1080 [the generic settings] for that old LCD most of the common variety these days for the past 5+yrs can handle 1080
Bill Dudley is our Pi expert.
oook go get him
Last weekend he found some issue and wasn't able to log in remotely.
So we cannot check any Pi settings because we cannot see its display. :)
wait you said the smaller monitor was only to fit in the rack, so you never had a monitor at all ?? umm, this sounds -you-know-what if you can't log in remotely that's a diff issue [I'm sure he knows what to do there] but --at least-- you like to get it working first, before trying to shrink anything, just use a modern LCD for now for this, that handles 1080[generic setting] -- _ ____ / \__/ Scotty, We Need More Power !! \_/ _\__ Aye, Cap'n, but we've only got 80 col's !!
