Good day Stevenpennock,

What screens are you using and what cables or adapters are you using ?

In general …

To make a HD 7850 work with 6 screens you will need to enable the Eyefinity feature.
You do this by using the/a DP ouput on the Graphics card. OS need to be Vista or newer.

If you connect Screens with DP input you can just use normal/passive Mini-DP to DP adapter and normal DP cable.
if you use Screen without DP input you will need to convert the DP output to DVI/HDMI/VGA with adapters that support Eyefinity and after the frist 2 screens these adapters also need to be Active.

Active Adapters:
CAC-1102
CAC-1152
CAC-1170

So
Screen 1: Passive Adaper Mini-DP to DVI or HDMI + normal cable to screen
Screen 2: Passive Adaper Mini-DP to DVI or HDMI + normal cable to screen
Screen 3: Active Adaper with Eyefinity support Mini-DP to DVI or HDMI + normal cable to screen
Screen 4: Active Adaper with Eyefinity support Mini-DP to DVI or HDMI + normal cable to screen
Screen 5: Active Adaper with Eyefinity support Mini-DP to DVI or HDMI + normal cable to screen
Screen 6: Active Adaper with Eyefinity support Mini-DP to DVI or HDMI + normal cable to screen

You can also use active adaters on the first 2 screens but as you have noticed, this is not a necessaty.
