While the idea of gaming on six monitors does sound attractive, it appears that using three monitors will probably remain the best combination.

The problem is pretty simple, but currently with no solution. Connecting six monitors naturally requires stacking three on three, which leaves a few thick black lines on your “display”, or rather like you’re playing behind bars.

The problem will probably be less evident with bigger screens and further distances from the actual display, but that’s not the solution. Unfortunately, the only solution would be to start producing special monitors, which seems to be highly unlikely.
