VGA Monitors, Sound, And More Speed (Take 1)

So the idea here was that, having got the Pi running using a TV, I would now make the move to a PC monitor which is in a more convenient position. However......I'm getting nothing from the monitor.

The problem seems to be with this HDMI to VGA cable adapter I needed to convert the HDMI to a standard VGA monitor.

Apparently you need to fiddle with the Pi's config.txt file to get a picture. Here's a helpful comment from 'GeekDad' on Amazon:

"I got this to go with my son's Raspberry Pi. At first it didn't seem to work, but after some googling managed to get it to work by editing the /boot/config.txt file on the SD card. First try with the hdmi_safe=1 option, which should give low-res (VGA) output when booted. If that works it is a matter of turning off safe mode and finding the settings that work for you. I tried:
disable_overscan=0
hdmi_drive=2
config_hdmi_boost=4
this worked after a reboot and gave full resolution on my old Samsung SyncMaster 172v. Haven't checked if all these options are needed.
So the product works with the Pi but you may need to experiment a bit to get it to work with your monitor."

Ah well. I shall report back soon hopefully.
