Checkerboard: crosseyed ghosting removing method
There is a big problem of crosseyed ghosting (when post-image for one eye is visible with second eye) - very annoying artefact on CRT and LCD monitors when using shutter-glasses.

There are 3 reasons for cross-eyed ghosting: 1) inertia of phosphorus (CRT) and LCD-screen elements; 2) transparency of glasses when they are in closed mode; 3) time-synchronization of open/close glasses's action, when shutter opens early or close lately. The main reason for NVidia glasses is 1st - inertia of screen; by removing it, crosseyed ghosting will be reduced significantly! DLP users report almost absence of crosseyed ghosting, - switching of screen elements is ultimately fast there, resulting to no noticeable inertia, so 2 and 3 reasons are very little for Nvidia glasses.

If every single pixel will be linked to image for 1 eye only, there will no be crosseyed ghosting caused by screen's inertia at all. Technically easy way to do this - checkerboard method, wich is allready used now for DLP sometimes (because of speed limitations of electronics, such as HDMI connection).

Have NVidia any concrete plans to make checkerboard mode avaliable for CRT and LCD monitors, so people could use them without this terrible artefact? It's shame that NVidia still ignores needs of customers who find crosseyed ghosting disgusting and unacceptable, while to program this mode available for CRT and LCD (when it exists allready for DLP) is a question of a ONE day.

From support: "NVIDIA has no plans for checkerboard or interlaced mode for LCD or legacy CRT monitors. Thanks for your interest".

So guys this company do not care that its product is unusable wth LCD and CRT monitors, even understanding that to make so is very easy. Shame.
