Alex, that's assuming he's got a
HDMI input... as the expansion board only supports DVI-D
(HDMI) which is digital. VGA, etc. is analog. Sure, it only
takes a few resistors to make a cheap D/A for VGA but there
aren't any drivers and no support built in. Even the Parallax
Propeller can do VGA or composite (can't do HDMI) but it is a
shame that there is no support (on any of the expansion
boards) for VGA. So, it's either HDMI (try finding a 7 or 8"
HDMI monitor) or LCD. Why is it everyone has forgotten
VGA/SVGA? It goes from LCD straight to HDMI and a HDMI
(DVI-D) to VGA converter is $$$ and HUGE (size) compared to
the Gumstix. What happened?
You state, "overo with tobi expansion will do
vga/svga via a hdmi connector" but where is that connector?
Are you forgetting you're going from DVI-D to an analog
Could be more than just a few resistors, it depends on the chip
video output and the number of colours needed in the output.
I keep an old lcd for fpga projects http://www.fpga4fun.com/PongGame.html
but replacing it with an adapter cable(much nicer to run on a
24inch monitor than a 15").
No not forgetting.
The hdmi(dvid) to vga converters range from around $70 to $200
depending on brand and quality
unfortunately the choice is either one of the cables or a newer
I thinks its more a matter of space , can fit 2 -4 hdmi/mini display
port connectors in the same space as a vga connector
more if you use the vertical versions and whats the easiest (least
number of chips) to do the outputs.
Also vga is on the way out , not so easy to find a monitor with vga
The next gen Dell monitors are supposedly dropping even the dvi
Some of the new desktops have the option for mini display port (not
just macs) , the dell on my desk here uses display port.
The other option is to go for something like one of the marvell
openrd boxes that has vga output

what the software is like.
So a media player the sata onboard and e-sata would be handy for
I'm tempted to try one of the guruplugs myself (well if I had the
Main downside of both is the complete lack of gpio's.
Its always a trade off for the features you need.
or to go for hdmi to component output - again not cheap.
