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.

Unlikely to be feasible at all without some serious engineering. That's
something that's a lot easier with a CRT set.

Have you considered digitally flipping the image with a computer before
you send it to one of the monitors?

With an LCD screen, flipping the picture would require some serious
engineering.

I would suggest getting a PC with a compatible video I/O option, and the
proper software package for what you want to do.

There is a manufacture in New York called Q-TV. They make LCD monitors
that can be ordered with a built in processor for video reversal. These
monitors are very expensive.

Thanks to you and bz for reminding me of the PC processing option. It's
one we talked about some time back, but may need to revisit.

Do you have a link for Q-TV? I didn't turn it up on Google. (I mean, uh,
the other search engine I'm using while I'm boycotting Google)

Below is the link for QTV. They custom manufacture monitors for
specific applications.
http://www.qtv.com/


They may send you to a company called Applied to do the purchase.

Thanks, I'll look at them more closely. I did find that site before but
seemed like it wasn't the right one.

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 ...

Well, if you can locate a LCD TV that can flip horizontally:
Flip it once mechanically vertical.
Flip it once electronically horizontal.

Taa Daa! :-)

Hi Smitty. Lots of the LCD monitors used in airports and train stations
etc, are used in a 'portrait' fashion, and often appear to be pretty
'standard' looking types, turned on their side. You also see them being used
as menu displays, alternated with advertising material, in restaurant
windows. I guess that whatever is driving them may well be producing a
picture that's rotated by 90 deg, rather than the drive being normal, and
rotation taking place in the display. Until you came up with this question,
I'd never really considered the 'mechanics' of how it was being done.

Good thought Arfa, but I've always assumed that the image was flipped on the
computer before it goes to the monitor. Otherwise you would have streching
problems unless you designed your video for being flipped this way and after
all of the trouble of doing that you could have just flipped the video.

Most LCD projectors that I am aware of are capable of doing this. Maybe you
can use one of those or a CRT.

Samsung RPTV 'DMD' can allow flipping of image on the horizontal and
vertical axis via the service menus.
Not too sure of your application, as posted, most of the DMD and LCD
versions allow image reversal on both axis.

Hmm, RPTV might be OK in theory, but size is an issue. Our application
is 26" and 37", which is small for rear projection.

Thanks, we actually started with the projector concept, three years ago,
but the customer opted for monitors... CRT's are too bulky.

I have a Haier TV I use with my Parasound C2 controller, with this
"flip-around" feature.

One would assume that, if the chipset supports this feature, it would be
available to the user. Ergo, the chipset probably doesn't.

I'd contact the manufacturer and ask. Perhaps there's a pin you can pulse to
make the image cycle through its display modes.
