And that is because the emitter is powered by the screen and its presence is detected via the HDMI monitor cable (and the signal to the emitter is sent the same way). Use of these screens is via different driver option (stereo option of 12) and there is a more limited range available.
I have no experience of running with this option, as being early(ish) adopters, we have a mix of Alienware OptX AW2310 and Samsung SyncMaster 2233RZ screens. I would be interested in how stable the stereo is, when a low powered graphics card is under heavy load. Having a graphics card with more power is not a waste of money (the CUDA drivers used by the molecular simulation groups show what can be done). The extra cost is quite small compared to the costs of getting crystals in the first place!!
