how to get the dual screen to work on windows 8

[gaily]

okay with the Toshiba windows 8, no matter what I do I can't the computer to recognize or detect another screen. I will so me 2 screens and I got it to project to the second screen, but everything is in reverse, what should be on the laptop is on the tv and what is on the TV is on the laptop. Also when I click on the second screen on the laptop (identify) is say 1 on both little screens number 1 and 2 both identify as number 1. I even tried the settings to make identify the second, it keeps saying no second screen or monitor detected. Do you still use the pc to Tv converter with this windows 8. I am at my wits end, I have been trying to get this work for 4 days. It did work once but as soon as I turned everything off. thinking horray when I turned it back on later same crap and I haven't been able to get it to work sense.
