Yesterday's Hero Runco DTV1200 questions

Over the years I’ve studied everything I could find for the Runco dtv1200 (Barco Cine 9) set-up but have never found anything related to the following settings. Namely, what are the optimal setting for these menu items?

Service Menu > Adjustment Mode > Service Mode > Common Settings:
Flyback Turnover Point (090 to 130 KHz)

Option 1 (on or off)

Memory Banks (on or off)

Service Menu > Adjustment Mode > Random Access > Picture Tuning:
Sync (fast or slow)

Peaking (off, Low FQ, Mid FQ, or High FQ)

I’ve experimented with various of these settings and can not tell a difference. My setup into the Runco is via a Moome IFB. PJ is set for 1080P at 67.5KHz Horizontal and 60Hz vertical. Considering a VP for CMS and read the Lumagen can be set with various scan rates, so think the settings (Flyback, Sync, Peaking), may be directly affected.

Appreciate any help in understanding how to optimize these.

Richard

You might want to head over to Curt Palme's forum.

Having fun playing the new mobile game Volley Village

Hello Richard,

Here the optimal settings for HT use:
1. Option 1 - Off
2. Memory banks - On
3. Sync - Slow
4. Peaking - Off

Some explanation:
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.

Cheers,
Stan

Stan, thank you very much. Yours are the first explanations I've found regarding these settings and much grateful. Richard
