I’m running an Oppo BDP-83 to a Marantz VP-12S3L DLP projector - which is DVI (720p) - and project it to 110”. The effect of the Darbee works in the system, however, whenever the Darbee is physically in the chain there are numerous “sparkles” that appear, most visibly in the blacks. I’m a film guy so if this were a 35 print it looks like random flecks of dust/light at 1/24 second. They’re all over the frame, constantly popping on and off in random places – possibly a hundred at a time. The image is watchable at my normal 15’ viewing distance, but the added “noise” (or whatever it is) is not an acceptable trade-off for the benefit.
I’m hoping it’s a cable issue – since what I have is pretty make-shift right now. However, I’ve tested each cable without the Darbee in the chain and the image is fine.
Here’s the chain as I have it: Oppo 83 → Oppo HDMI cable → Darbee → HDMI cable (Male to Female) → HDMI to DVI adapter → DVI cable → Marantz projector.
I’ve tried Oppo 83 → HDMI to DVI adapter → DVI cable → Marantz. No problem, but no Darbee.
I’ve tried Oppo 83 → Oppo HDMI cable → Darbee → HDMI to DVI adapter → DVI cable → Marantz and, oddly, that gives me no image at all. It appears to need the HDMI cable (Male to Female) between the HDMI to DVI adapter and the Darbee to get an image.
Any ideas on what the sparkle effect/noise is? Any thoughts at all would be greatly appreciated! It’s possible that the projector is pre-HDCP, but I’ve had no problems before integrating the Oppo, for example, and the image is there, just with the added noise/sparkles.
BTW – I’ve tried quite a bit more than this – in the event a powered switcher would help. However, my original switcher was a Gefen DVI model and had the same effect. Those notes below if it’s helpful.
Originally I ran the Oppo 83 and a DirecTV receiver to a powered Gefen DVI switcher with a single DVI run to the projector. I tried installing the Darbee between the Oppo and the Gefen. Didn’t work. I removed the Gefen from the equation and bought a DVI to HDMI (female) converter and inserted the Darbee there. It worked but a got the sparkles. I removed the Darbee to test the DVI/HDMI adapter direct into the Oppo and it was clean.
I swapped out a higher quality HDMI cable between the Oppo and the Darbee and that had no effect. I then re-introduced the Gefen switcher but put it between the Darbee and the projector. That worked but had the same sparkles in the blacks.
