I don't notice any processing at that setting and you can still see that the image is enhanced. Over 50-55% or so and I start to notice, what appears to be, processing from 12.5 ft away on a 125" screen.
Comcast is a no go through the Denon. I either get just sound and a blank screen, or flashing magneta and a solid green screen, or a black screen with no sound. Have tried multiple HDMI cables (4-6ft), and different HDMI ports on the receiver. If I hook the Comcast receiver up directly to the Darbee and then to the projector it works great mad.gif So it has to be something with the Denon and Darbee that Comcast just does not like. I have three things left to try:
- Try moving the Darbee closer to the projector
- Buy a longer higher quality HDMI cable (Blue Jeans, I am using a cheap no name and cheap Monoprice HDMI cable now)
- Use component cables with my Comcast box and an optical cable.
I am not opposed to going with component, I have tested before and there is zero noticeable improvement for me between HDMI and component.
Hopefully I can get this working with HDMI, but it is rather frustrating, especially since I just switched to Comcast from DirecTV. I just got tired of climbing on a latter on a 3 story house in a snow storm and trying to get snow off the dish to watch TV, and switching to Comcast saved me like $100 a month...
Ughh....

Have you tried and change the Comcast DVR from native to 1080I output?

But darbee has no component connections, it's a hdmi only device.

Another possible solution is to get an HDMI switcher (like the monoprice ones), and bypass your Denon HDMI switching. This means optical for your sound, and (if you notice or care) you won't be getting HD audio surround, just a little better than DD/DTS quality.

No dice. I get audio, but it is stuck on the home screen of my projector with no video.

I am thinking component and optical from my cable box to my Denon then out my Denon through the Darbee and into my projector. I certainly hope this is an option or I may be selling the Darbee since this is getting really frustrating trying to make HDMI work with the Comcast box. My Comcast receiver is the RNG-150 HD receiver. I may try the Darbee with my RNG-200 HD DVR upstairs to see if it has the same issues. If not, I can swap boxes and have the HD DVR downstairs. Not ideal, but an option.

Sorry that did not work for you. The component option will work. But I believe the Denon HDMI setting has to be changed too. Try a search here for the Denon.

I played around with component today but the audio was horrible. Was getting a hum. I also tried placing the Darbee next to the projector and no deal. Get the green and magnetta flashing screen.

I have pulled the Darbee out of the mix and will order a couple of Blue Jeans HDMI cables to see if that solves anything. Otherwise I guess I can use the Darbee just for Blu-Ray, but that is a letdown for sure as I watch a lot of sports.

I tried the Darblet upstairs with my Comcast RNG 200 HD DVR, my Onkyo receiver, and my Panny plasma and no problems at all. Everything worked.

Went back downstairs using the same cables and no go with the PJ and the Denon. Must be something the Denon, Comcast, and Darbee just don't like with each other. I now have the Darbee going from my BD player to my Denon then to my projector and everything works fine so at least I can use the Darbee with Blu-Ray and the PJ (movies are about 50% of the usage) until I can try some different cables with the Denon. I am really wondering if it not a cabling issue for some reason. I was getting some HDCP compliant issue splash screens with the latest attempt through the Denon and Comcast box. I also might try hooking up the Comcast HD DVR downstairs to see what happens. But I don't see that working as I really don't like turning on the projector for 15-20 minutes to record shows to watch later.

If I could sum up my afternoon it would be this:



Only substitute "Khan" with "HDMI"

Has anyone tried using the RedMere HDMI cables with the Darblet? I tried using a couple with the Darblet today, one out from my DUO to the Darblet and another from the Darblet to the TV. These cables have worked well with the source devices I tried, but there were issues with the Darblet where the picture would blank out periodically. I was only giving it a try since the cables and connectors are so much smaller than normal HDMI cables. But I guess I'll stick with the larger HDMI cables for the Darblet and just use the RedMere cables with some of my source devices.

Does the Denon have any sort of video up-scaling capability?

I mention this because the Blu Ray is probably sending a native 1080p signal to the Darbee and it is passed properly to the projector.

The comcast box will be a max of 1080i. The receiver may be doing some upscaling that the Darbee or the projector don't like.

Might look into the settings for the receiver for a passthrough setting for video. My Denon 1712 does no video processing - just passthrough - and the 1080i signal from my Sat box works fine.

Just an idea to try.....

I have no issue with Comcast but I don't use their STBs. I use a PC with a Ceton or a Tivo HD. I also have a Radiance after the sources and send only the audio to the Denon. The Darbee is quirky no doubt. 2 days ago the screen started flashing on and off going occaionally to snow. Even though everything is on UPS I still needed to remove the power plug for a couple minutes to get the Darbee behaving again.

I tried a ten foot to the Darblet and a six foot to the TV. I also tried the Slim and Ultra Slim with the same results. If I took the Darblet out it was fine. But maybe there is something going on between the iScan DUO and the Darblet with the RedMere cables in place.

I still can't believe how thin the RedMere cables are.

That is an excellent point. The Denon model I have does have upscaling via HDMI and I believe it is turned on by default. I will disable it and see what happens. Certainly seems that this could be the culprit. The one thing that keeps bugging me is the different issues trying different cables. Sometimes a magnetta and green flashing screen with no audio, sometimes a black screen with audio, etc. I ordered a couple of Blue Jeans HDMi cables to see what happens.

Thanks for your help.

FYI - I'm using 6' monoprice cables on both ends of my Darbee and have had no signal issues. They were very inexpensive cables.

In fact, all the HDMI cables are from Monoprice.

The RedMere's are directional--ie. they only work in one direction, so any communication between source and destination must be one way. I don't think this is an issue, but something to be aware of--they can't be hooked up backwards.

I didn't try hooking it up backwards. Although if I had I would not have expected to see a picture. It's really no big deal. I just went back to my Monoprice $5 cables which work just fine. And I ordered a few more to use with my 3D capable devices to make sure I won't have any issues since I had not purchased any in several years. They have always worked great over the years. I was just trying out some of the RedMere cables because they were thinner.

Perhaps the iScan DUO will not respond through the Darbee unless it detects a display at the other end, which it would not with a RedMere cable.

All my HDMI cables minus one are Monoprice. Some are under 6' and there have been discussions on this forum that some people have had issues with cables under 6'.

I did disable I/P scaling on the Denon and nada. Still getting the flashing magnetta and green screen.

We will see if the higher end Blue Jeans cables (8') make any difference. If not I think I will just have to accept that the Darbee will only be used with Blu-Ray for the time being. Glad I picked ths up for $200.

I seriously doubt brand will make any difference. If the Cable meets specs it meets specs. I fully understand the debate about brand name HDMI cables, if you feel a brand name is better, no problem.
But 3' HDMI is known to cause problems, not just with a Darbee. I helped someone with a Dish receiver problem and HBO, couldn't get a handshake. I didn't think of it till he happened to mention a 3' cable. When I told him to use a 6', problem solved.

Exactly. I just received my Darbee. It would not work 98% of the time.

I sent it to Darbee to test and they found it worked perfectly. I drove to their shop and picked it up and re-installed using Larry from Darbee advice: You should try swapping the 3 footer for a 6 footer.

This time I took out my 3' cable and exchanged with a 6' cable. My Darbee is working perfectly.

I e-mailed Larry and told him of the success. He replied:

Over 6 feet and under 25 feet apparently do not accumulate error. Under 6 feet are blamed for accumulation error. Check the forums and Google.

I'll need to remember that. I have a bunch of 1.5ft and 3ft HDMI cables that I use.

I have a Denon a100, directv dvr, hd TiVo, dune player, Sony DVD recorder, roku xs, WD live, ps3 slim, pch 200, oppo 95, oppo 103, and a mono price 4x2 hdmi matrix switch. With the exception of the 15 ft hdmi from Denon to panny projector, not a single cable is over 3 feet, with about 90% of them being 1.5 feet. Denon receiver to darbee is 1.5 ft mono price cable to 15 ft cable to projector. No issues at all in my set up...

Well the Blue Jeans cables are not that expensive. We are not talking Monster cables here. I hope the issue gets solved with the longer Blue Jeans cables, but I am really thinking it is just handshaking issues between the Darbee and Denon for non 1080p. I doubt there is any easy way to resolve it. I will probably upgrade the receiver sometime in the next 18 months, and it least Blu-Ray works with the Darbee.

It's not about the brand or specs of a HDMI but the quality of construction. I'll take a Blue Jeans (Belden) constructed HDMI cable any day of the year. Specs mean nothing if the cable is shoddily built. You can read reviews about different HDMI cables all over the internet and even Monoprice cables occasionally fail. I have a mix of Blue Jeans and Monoprice in my system, a mix of 3 foot and 6 foot lengths plus a 40 foot length to my projector and I have no problems with my Darbee.

Why would the RedMere cable be any different from a passive cable as far as what is detected at the other end? Also Karl S above reports success with the RedMere cables and Darby.

I agree you are right about the 3 foot versus 6 foot cable length sometimes being a problem but there is a lot more to it than "If a cable meets specs it meets specs". Here's a link to a relatively recent post by Bob Pariseau (who is probably considered the most knowledgeable and helpful poster in the Oppo 93 thread) commenting on the various problems of HDMI and some of the possible reasons for these problems. Worth the read IMO. http://www.avsforum.com/t/1291855/official-oppo-bdp-93-owners-thread/21000#post_22040275
