Here the optimal settings for HT use:
1. Option 1 - Off
2. Memory banks - On
3. Sync - Slow
4. Peaking - Off
A lot of the options in the DTV-1200/Cine 9/Cine Max menu's, are a legacy from the software in their industrial predecessor, the Barco Reality 909. Those machines weren't designed for home theatre purpose, but mostly used with some insane (at least for that time) computer resolutions in 4:3 aspect ratio, oddball configurations, stereoscopic and augmented reality purpose. When used with HD video, most of the option you mentioned are irrelevant.
Option 1: when on, enables you to control an optional piece of hardware mounted in the projector (not present in any DTV-1200/Cine 9/ Cine Max)
Memory banks: when off, only one memory bank will be available for a given source. When on, 8 memory banks can be created per source. If you've already created different memory banks for a source and you switch the option off, only the first memory bank will be visible in the list. The nice thing about how memory banks creation works in Barco's, is LDI (Linear Digital Interpolation). When the projector locks to a signal, it will "guess" all the settings based on an already existing memory bank (the one with the closest timings to the new signal). This way, only a slight touch of geometry and convergence is needed to get it nailed. No need to start from zero. However, when the projector is moved, it is advisable to delete all stored memory blocks and start from scratch.
Sync: The fast position is used to compensate for unsteady sync pulses from older video playback sources, reducing horizontal jittering or tearing at the top op the image.
So leave it to slow for HD video.
Peaking: Improves the contours in the image, and you can choose at which frequencies that must happen. Low=15-45Hz, mid=45-85Hz, High=85-110Hz. Leave it to off, each image enhancement in the projector should be switched off. Use the scaler to improve the picture.
Hope it helps.
