Video Clean Feed on a second monitor when using dual screen

Hi. Is there an option to set video clean feed (full screen preview) to be shown on a second monitor, when using dual screen mode? My options are grayed out until I disable dual screen, but I would like to have Resolve interface on both monitors, and only when I need fullscreen, I would turn it. As for now, it always shows up on my main display with timeline. Why it doesn't allow me to change video clean feed to second display in dual screen?

I think you have to choose one or the other.

The best option, of course, is to have both using a proper I/O device.

So Resolve has an option to show video in fullscreen mode on primary monitor, but to show fullscreen on secondary monitor (instead of primary), I need to buy additional card? That's a pity it just can't be changed in the settings.

I think it's a Studio version feature to put the video clean feed on its own monitor. I have that version and I have three HD monitors - I sometimes use dual display mode with the video clean feed on the third monitor and it works really well. All three monitors are just plain Windows monitors connected to two outputs on my GPU and to the motherboard video output.

I have Studio version, but only two monitors. When I am doing color correction I would like to have fullscreen on secondary monitor, as all features which I use are on primary display. As for now, I need to make a change, then turn on fullscreen and see it it's okay, then turn fullscreen off and again make next change. It's annoying.
The second option is to turn off dual display mode, but I like working in this mode.
