How and why is the video mirror flip accomplished for the top monitor?
Because the user sees a reflection of the top monitor it is necessary to do a mirror inversion of the video going to the upper display. This can be accomplished in the drivers for the graphics card or in hardware. With each system, Planar supplies a PCI Mirror-Flip card that plugs into your computer. It receives a DVI signal in, flips the image one line at a time and send it to the top monitor. The PCI Mirror-Flip card does not require any special drivers and introduces insignificant (less than 50 microseconds) latency.There are also a couple of drivers under test that will eliminate the PCI Mirror-Flip card. Matrox has a solution for Clone mode in their Parhelia cards. nVidia has a solution for Dual Display mode in their GeForce cards. Planar has a solution for the Dome DX card that is used to operate Planar’s medical monitors like the C3 and C5i.

A stand alone “DVI Inverter Box” is available as an accessory if there is not a PCI slot available. The ATI FirePro graphics cards from AMD have the image mirroring function built into the drivers.
