Need help: Using my LinuxLite laptop in my presentation

[linuxNewbie]

Menu, Favorites, Help Manual

Thanks Valtam. I think It's solved now, I successfully able to work with 2 monitors. Hopefully I will not have any problem with the projector I'll be using.

Installed the proprietary 3rd party software - ATI/AMD Proprietary software (amdcccle - for my Lenovo G405 E1 Essentials)
Figure out correct setting of dual monitor system by trial & error (using my old CRT monitor)

Now Option #1 (Pressing F10 works)

I realized how noob i am (wasn't able to find the correct information at the Help Manual)

Thanks a lot really for the big help.
