DVI / VGA to USB over Bluetooth? Answered

I do graphic design and computer animation.  

I am making my own wireless drawing tablet.  I have a bluetooth pressure sensitive drawing tablet.   A 16" (16x9) laptop display, bluetooth adapters, dvi / vga to usb adapters and various strong enough rechargeable batteries.

The tablet is bluetooth enabled.  The display is using a dvi / vga to usb adapter.  Everything is working.

What i need to figure out is how to stream my low res display from usb to bluetooth over to my computer's bluetooth.

Any ideas?

The bluetooth protocol may not be designed to handle something like streaming video or even normal static displays. That is a lot of data to pump through even with a low res display.

Then again, I don't get what you are doing. You have a bluetooth drawing tablet. You have an external laptop display of some sort or is that the computer's display unit linked to your computer with USB? You want to create a cintiq type device that is a portable drawing tablet linked to your main computer? Where is the low res display coming from?

Yes i am trying to make a portable Cintiq device. The device would not be directly connected to anything. I want to get the vga signal over bluetooth, or some other method, to my desktop.

I have an LCD from a laptop which is connected to a vga converter adapter. This makes the laptop LCD work like a native desktop LCD. The LCD is powered by an old laptop rechargeable battery.

Then i have a vga to usb converter. The vga to usb converter lets you plug in vga displays into a usb hub or port, so you can add multiple displays.

Then i am trying to somehow push that display signal through usb to bluetooth over to my computers bluetooth.

I have also thought about not using bluetooth and doing some kind of wireless vga?

Do you know if there is a wireless vga device for computers?

Also i have seen all this done before with bluetooth. I lost that link and tutorial though. Although that method used only a 320 x 480 (or less) display, which is not possible for me because of too low resolution..
