So here's the thing:
Few days ago, I bought a projector, and this projector has two entrances:
1) Mini USB
2) AV IN
The mini USB only lets you connect an USB Drive via an adapter and read the data from it, you can't use it to connect your PC to the projector via USB cable, the projector doesn't recognize that connection as a usb device itself, The AV Connection uses a female RCA Cable like this one:
http://50.30.33.54/gaolinimages/images/desc/61/20101105/A0366000JE/InsetImag...
(The small black one goes to the projector and the other three females are free)
So what I tried basically was to connect that cable to the projector and then used this one:
http://www.pcwizkid.co.uk/images/usb%20to%203rca.jpg
To connect it to the computer via USB, in theory Fedora should recognize the projector as a second "monitor" and then the projector should show the image of the computer in the "AV IN" option right? but it doesn't happen :S
When I conect the projector to the computer via AV IN => USB neither the projector recognizes the computer or the computer the projector, did a test with a lsusb to confirm...
Am I doing something wrong? does I need a hardware converter or a program in order to this to work? Because once I conected my Fedora Laptop to another projector Via VGA cable and the same thing happened, with Windows/Mac computers everything worked flawlessly.
Can anyone help??

Have you tried?: xrandr --output VGA

If you look at the information for that cable you'd see....
Note: PC Computer Laptop can't use the cable directly
You can't hook this cable to the USB port of any system then plug the male RCA connectors to the female RCA connector and then plug the 3.5mm jack into your projector. The USB ports can't act as Video drivers....
You need to tell people a few things....
What is the make and model of your projector?
What type of system is your Fedora system? Desktop/Laptop? What is the video HW? If a desktop, what type of video card? Does it have one or two connectors? Many have a VGA and DVI connector and are capable to drive dual monitors.

@Edward M, Ed Greshko: It's completely generic, the projector doesn't have a brand, doesn't has a model. My computer it's a laptop with VGA port, the only cables I have are the ones I show in the following images:
http://bit.ly/HrV0KV http://bit.ly/Hs3qS1
(Same as above)
So, Quick idea: As the USB port is not capable to stream video, I was wondering if with this cable:
Maybe it will be possible to connect the projector to the VGA port of the PC and then select it as an output instead of the laptop screen resulting that in a projection from the computer to the projector?? O.o, In a "Diagram" My idea is:
This to the projector: (As it only has AV IN port exactly for this cable):
Then This to that cable:
And Finally the VGA end from that last cable to the VGA port of the Laptop, then maybe run the command issued above:
"xrandr --output VGA"
And as far as I understand it should result in projection from the laptop computer to the projector as it were a VGA monitor right??
What do you think? :)

Sounds reasonable to me....
You may not even need to us xrandr. You can simply try the Function Keys on your laptop to switch the panel to the VGA output. I don't have any recent experience running Linux on a Laptop as all of my systems are desktop systems.

Good. I'll buy the cable and Give a try as soon as posiible... I'll report the results.

It looks like this cable breaks out the VGA signal to a RGB output. If the projector excepts RGB video input, then it will work. (Is cable http://bit.ly/HrV0KV just for video, or audio and video both?)

Dumb question - does your laptop have an S-video output? If so, you can probably use that, especially if the projector has an S-video input.
Also, depending on your laptop, there may be more then one video "card" - so you can have the built-in display showing one thing, and the external video showing another. Or they can both show the same thing, but at different video resolution. If your laptop has this, you can use the GUI setup tool to set each screen the way you want.
There are USB video "cards" - I do not know how well they are supported, as I have never needed one.
I hope this helps... Mikkel - -- Do not meddle in the affairs of dragons, for thou art crunchy and taste good with Ketchup!
