In regards to the unstable picture, it is more than likely the adapter connection.
Make sure you are not using more than ONE adapter, and if it needs to be powered to provide power to it.
That being said, exactly what adapter(s) are you using? if you can email us a picture of your setup it could help pinpoint what the exact culprit is.
