We've been using some off-the-shelf LCD HDTVs in a 3D vision system. The
system relies on being able to flip (mirror image) the picture on one of
the monitors.


The feature was built in to the TVs we were using, but those models have
been discontinued, and we're having trouble sourcing this feature
elsewhere.


Any educated guesses on how difficult it would be to add the feature
ourselves? If it matters, we're talking about a vertical flip, not
horizontal.


Horizontal flip is fairly common to make a monitor into a mirror - or for
use as a camera viewfinder. But I wonder what the vertical flip was
designed for? But for vertical flip can't you just invert the monitor?

I thought that at first Dave, but it actually flips it horizontally as well.
Like everyone else, I don't think that it is going to be easy to do within
the monitor, unless you can find one that has been designed to have the
picture displayed in a different format, such as happens with the LCD
monitors that they use in airports, and in advertising displays now.

I used to work with a 3-D visualisation system 22 years ago. Used a single
CRT and a vibrating circular mirror driven at 30Hz by a loudspeaker attached
to it. Produced stunning results - almost like a 3D hologram 'floating' in
space, but was big and bulky, and too expensive to ever be a commercial
success. There was one sold over here to some university or other. It was
for a project to map the surface of some planet or other, from radar-derived
terrain data. I wonder whatever became of it ? Maybe it's sitting in some
dusty cellar somewhere ...
