Title: Betson Imperial / Kortek KT-2914 and Raspberry Pi
Post by: portwojc on March 10, 2015, 10:23:42 pm

Is it possible to have a Raspberry Pi work with a Betson Imperial / Kortek KT-2914 monitor?

I have a Raspberry Pi with powered HDMI to VGA adapter and a  GBS-8100 video converter (http://www.digitalsystemsdesign.co.uk/product_uploads/13153855771.pdf (http://www.digitalsystemsdesign.co.uk/product_uploads/13153855771.pdf)).  Hooking the VGA to the GBS card and then the output to the monitor doesn't show anything.  Going straight to the monitor I get the monitor complaining about the signal.

In the boot/config.txt I have tried

#hdmi_group=2

Along with

# 640x480   60Hz
hdmi_mode=4

or

# 800x600   60Hz
hdmi_mode=9

With no luck.  Any suggestions would be appreciated. 


Thank you,

Jason

You should not need the downscaler/converter.  The monitor accepts 640x480 VGA and 800x600 SVGA directly.  I'd figure out why it claims out-of-range when you try to supply those.  Chances are the downscaler isn't going to be happy with whatever you're actually outputting, either.

So skip the conversion board as it won't be needed.

I did find this link, http://www.raspberrypi.org/forums/viewtopic.php?f=29&t=24679, (http://www.raspberrypi.org/forums/viewtopic.php?f=29&t=24679,) the covers custom settings for the raspberry pi HDMI output.  That should help me work this out and give the signal the monitor wants.



Thank you.
