The manual specifies a 'windowed' option, but mine is a checkbox for Full Screen, and it runs full screen by default, meaning that I can't move it to the 2nd monitor.
edit 2018-08-25: May have a work around...though I should not have to do this for any product...I
show desktop, minimizing all windows
unhide my taskbar
swap displays so that the RoF will run on the NVIDIA
after ending RoF, swap back and hide the taskbar...then it is visible the next time it pops
The downside is that I think I must be careful to minimize all windows, because if I don't, then all the open windows impacted by the smaller effective screen size get resized.
I'm still not SURE that RoF DOES NOT use the NVIDIA if I run it on the smaller display, becau9se I have marked the file to use NVIDIA and I have it listed NVIDIA to use it. If there is a way to learn this from the program, please let me know..l
edit 2018-08-26: Seems that Windows will resize windows that are minimized. I have two choices so far: reboot after running ROF on 2nd monitor, because the taskbar is transparent, or close all my apps before unhiding the taskbar and swapping displays. Then restore the displays, hide the taskbar, and reopen apps. Means no quick swap to run ROF for a break. I'd like a 3rd option, but web searches have not popped any solutions yet.

I still cannot run easily on the 2nd monitor. There are steps that I can take to run there, but they involve closing all my apps, OR rebooting when I am done. Documented in another thread.
I /can/ apparently run on the NVIDIA card, which is usually dedicated to the 2nd display. I marked both Startup and ROF_UE to run using the NVIDIA card, and I then registered those programs with the NVIDIA control panel app. The result is that NVIDIA seems to indicate that ROF is using the card as it runs on the laptop, not on the 2nd display. I do not see a performance hit. Startup no longer complains about too little memory; in fact, it now reports that I am using less than half of available graphics RAM.
The upside is that I can simply run ROF for a few minutes when I get the time. The downside is that it then is not running on a larger display. Another post suggested that I might be able to run on both displays at the same time, for a larger (wider) view, but I have not yer discovered how to do that.
