​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,


then you can try alternate options,


and then here's some of the sites to provide the explanation of the various

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
* 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,
* 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

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
