BeagleBone Black Rev C + VGA/ micro HDMI

[Alishax]

Hello, I connected my BeagleBone Black Rev C to a VGA PicoP Laser projector SHOWWX and I am receiving the following message on my screen: video not supported at 60Hz.
I tried both a powered and unpowered VGA/Micro HDMI adaptor-convertor. It does not work. Please help! What should I do? Someone told me to take the adapter apart and find where the 5 volt power was coming in, trace the pin out to the adapter circuit board, cut that wire and soldered a wire onto it. Then, run that wire to the Beaglebone circuit board where the barrel connector connects power in. What do you think? I don't want to dommage my BBB. Thanks a lot

You don't need to do surgery on your BBB.

All you need to do is feed it a different set of HDMI parameters so the BBB and projector are using a format they both understand.

All HDMI devices are required to support 640x480 resolution at 60Hz, so start with that and make sure you can get a basic connection working. This page has information about how to do that:

New Problem: the PicoP VGA projector actually show the startup screen once and also the desktop for ten seconds and then, turn all black. Could it be the VGA/ micro HDMI adaptor? Should i give it 5V? I really need some help!

You may need to give the projector an external power supply.

We don't sell or use the PicoP projector though, so I really don't know anything about it. You'll probably need to contact the vendor who sold it to you for support.
