I assume you're using CRU. There should only be one detailed resolution listed when you start the utility for the first time, should be 59.950 Hz. Don't touch this one. Add another detailed resolution, use "Automatic - LCD Reduced" for 120hz. Make another for 96Hz, just in case you find your monitor can't do 120. Now using the arrows make 120 first on the list, 96 second, and 59 third. Now exit the utility and reboot. Your new refresh rates should be visible after rebooting.
I don't know what would cause a black screen after rebooting if you've done everything right. Sometimes if I reboot while set to 120, it'll be back to 60 when my computer restarts. Lately it's been sticking with 120. I've never had black screen issues though.
You might just want to wipe everything and start fresh. Do this by running the reset-all tool included with CRU as admin and then reboot. If you have an AMD card, make sure you have the option "Reduce DVI Frequency" checked when running OC'd refresh rates.
As far as the Test Mode watermark goes, I haven't found a way to disable it in Windows 8. I've tried every method out there and none worked for me, so I just live with it.
