NVIDIA has removed a specific Linux feature as of the v310 drivers due to the Windows platform



From Tom's Hardware:

Yet in v295, the Ubuntu user was able to get four monitors up and running. So why was BaseMosaic altered to support only three monitors instead? Nvidia explains. "For feature parity between Windows and Linux we set BaseMosaic to 3 screens," said "Sandpit" of Nvidia's Linux team.

What's interesting here is that Nvidia's proprietary Windows driver has features not found in the Linux drivers, but the company will remove specific Linux-only features for "parity." The comment indicates that the three-screen limit has nothing to do with a degradation of quality when using four screens, but a possible Microsoft request/demand.
