Remote Desktop Connection Black Screen Raspberry Pi [solved]

Readers Digest version:  Change resolution in the /boot/config,txt file

Long version

Replaced motherboard on my desktop to include installing new graphics drivers.

Tried to RDC into the Pi and got the black screen.  Connection was OK as I could SSH in.

sudo nano /boot/config.txt

had to change both the overscan (top,bottom, left, and right) as well as hdmi_group and _mode.
