I've read here (and in the Integrator Manual) that the FRC Mode 2, allows a wider range of acceptable refresh rates. But with my set it seems that FRC Mode 1 allows more (down to 50Hz from a PC on the DVI input, although not without some sizing errors). In Mode 2 the picture disappears and is reported as "out of range" as I reduce the Hz in Powerstrip on my PC. In Mode 2 I can't get HD 50Hz signals from our xbox. But in Mode 1 I can. And in Mode 1 you get all the Picture in picture functions. Why might this be? And why's might the image be squished to the side in Mode 1 at 50hz?
