Re: [GTALUG] FPD-Link adapter kits -Success
Top posting again. It all works. The recycled laptop screen is connected to the Pi through the M.NT68676.2A display adapter. The provisional instructions said to make sure the ground on the LVDS cable was connected to the adapter correctly or damage to the screen would result. The original Toshiba cable was tabbed on top so it could only connect in the correct orientation. In fact the pin offset on the connection ensures that the cable only fits one way, if gentle pressure is used. Other than that, easy as Pi, although xrandr can't report the correct gamma size of this adapter. The OSD works fine and so I'm happy enough. Now to check a the old screens, hopefully there a few LG in the lot and close enough to this modle to be able to use this cable. Russell Sent from mobile.

I went with this product as it has a number of signal inputs. Also available on the net is a usb EPROM flash tool, but I'm hoping to override/modify EDID data in X in order to test several closely related LCDs with the same cable.

The cost was $61, and some change. It took about six weeks to ship. I got the full kit with power adapter rather than trying to recycle the PS and backlight inverter from the tickle trunk.
Time to dig out the multimeter.
The general instructions are to power test the inverter first, then test

Not me. But thanks for posting this. I'm mildly interested because
of
two projects that I never get around to.
Here's a slightly cheaper one with VGA input only. This place drop ships from Flushing NY, although they say add 30 days for international delivery, most of them sellers I've viewed say that somewhere.
These pre assembled device matched units all seem to come from the same manufacturing campus in China.
I'm currently thinking of this one.

You have to make/repurpose your own LVDS cable. However, there is a ink
to step by step instructions and a they provide their own utility for loading EDID. This would be good for me considering where I'm starting from. However, in my case I may be wrong in my assumption these Toshiba's are all using LG.
There is also this; as well as the native Linux EDID tools you can use
to tinker Xorg.

From what I have read so far, it is possible that if any of the
adapters sold now is hooked up correctly ie. voltages and pin assignments are correct, you will get some sort of output.

I see this as a transport issue related to supply side economics. You
can invest in better technology for smaller items because your risk of damage or loss is spread out over a larger lot per container. The larger

Nice work! I see that someone has got first-gen Nexus 7 displays working with the Raspberry Pi, too: https://www.raspberrypi.org/forums/viewtopic.php?f=44&t=158525 Stewart
