Can anyone tell me whether the sync outputs of the RCA DTC 100 are positive or negative? I assume them to be negative but a confirmation would be appreciated.


Thanks.

At this point, unless someone else tells me differently, I would have to assume so. Both my DISH and ExpressVu receivers work perfectly with my projector (which is a highly modified Harman DPM8)but neither my DTC 100 or my GI HDD200 sync up. So, I'm assuming based on what others are telling me, that I'm dealing with a sync polarity problem.

Thanks, you just answered my question as to why my DISH 6000 works with my projector and the DTC 100 does not.

Rpurohit,



I picked up an ExpressVu 6000 HDTV decoder yesterday (same hardware as the Dish 6000 box) and it works fine with my BarcoGraphics 800! No special sync inversion circuitry required!


I used a HD15 -> 5BNC cable from the 6000 directly into the Barco with the H and V sync BNC's combined with a T-connector. I didn't try it without combining the syncs.

I'm not sure if this helps make it work, but since I need this for my GeForce2 HTPC output, I figure I would try the HDTV box this way first as well. Now all I need is a good quality 2-1 VGA switcher with autoswitching and I'm set!
