Hi, Saw my first DLP projector yesterday - a Runco CL500. My main aim for the demo was to see if I get trouble with the rainbow effect before I jump for a new HD2 model. Did I see any? ... Well I think I did, only a couple on normal scenes. However when looking at scrolling credits and moving my head rapidly up and down when white text seemed to be multi-coloured. Admittedly I wouldn't watch a film constantly moving my head up and down but it did but a downer on what was otherwise a superb picture! I am used to LCD so the sharpness wasn't as good, however the blacks were a revelation. My question is does anyone know what type/speed of colour wheel is in the Runco CL500 (Runco don't seem to specify this!) Thanks.
