I hooked up my Pi 3 to a Samsung B2230 LCD monitor via an HDMI to VGA converter cable. The L.E.D's on the Pi seems to be working fine (RED on and GREEN intermittently). However, I have no display on the monitor. I have read about the config.txt file and the "1" to "4" keyboard keys that will select different modes for the monitor, but that did not work.
I have Raspbian on the 16GB SanDisk. Power is a solid 5v/2.5A (via a UBEC).
