Sorry if this has already been answered but my searches haven't revealed the answer yet... I have an ElectrohomeECP 3100 and am trying to run it from the pc using Dscaler to save buying a dedicated hardware scaler. I am having a devilishly difficult time getting a stable picture - using powerstrip controlling my Matrox G450 I get a rolling picture. I can monkey with the various scan rates and fine tune the porch numbers to speed up or slow down the rolling but I can't quite get a still picture. The pj has manual or auto H and V scan adjustment but even with this I can't 'tune' it in exactly. Does anyone know the EXACT settings I need from Powerstrip. I assume that the projector behaves similarly to some of the other leading makes (Electrohome seem thin on the ground over here) so I'd be interested to hear from you Barco owners out there! BTW, the pj displays an image fine from a dvd player - so its not a hardware fault. Help me obiwan, you're my only hope.
