An extra wide, 256 colour display!
With two DVI-I sockets on board, one of the selling points of Elesar‘s Titanium is the ability to drive two displays side by side. RISC OS doesn’t (properly) support this, but it can be done by fooling the operating system into treating the two screens as though they are one. The software to do this has been available since February 2016.
Much more recently, an updated ROM image was released in July of this year that allowed the board to use 256 colour screen modes – which might sound odd to make a point of with modern systems (including the Titanium) capable of running with 16 million colour displays, but there is some older software that actually needs to run in screen modes with a more limited colour depth; so called “paletted” modes.
