I have posted instructions on how to try out Use3Renders on a single monitor in the link below. You need to do more than just set Use3Renders=1 to get this to work.
If you post your current [window] section of your conf.ini I could modify it here for you if you want to see it on your system.

Keep in mind that on a single monitor, even widescreen, that it will not really be too usable.
It is intended to create three different 4:3 aspect ratio windows (ie like 3 views each 1024x768 ), each representing a different view on each monitor. To fit that on a single monitor means the height will be very small.
It doesn't draw a view directly to each monitor, it just draws a view that is 3 times as wide as normal and each 1/3 of the picture represents a different view. It requires hardware like the TH2G or software like UltraMon that sends 1/3 of the view to each monitor. Because the view was draw in 1/3 sections and the TH2G sends 1/3 of the view to each monitor it gives the perception that each monitor has a different view.
But you can display this 3 view on a single monitor, Il-2 doesn't know or care, it's just that as I said before it is not really that usable on a single monitor because it maintains a 4:3 aspect ratio so 3 views across a single monitor means that the height is really small.
