Right, I knew August was the magic date, but assumed some vendors might still have older product sitting around. I will say that by clicking around for a long while on the Darbee authorized vendor list, I found one smart seller that specified the SW and FW installed on their currently shipping units, and it was the latest versions from August 2012 (Software version:2.8.221 and Firmware version: 1.3.21)

I won't get into names, but if you're a baseball fan, go Indians.

Thanks erkq.

I have the darbee working with my integra dhc 80-2 between the integra and my Kuro 151 without issue . I did need to use redmere HDMI cables to get stability.

Like I said, "common occurence" . I didn't say "always a problem" with Onkyo/Integra receivers.

You're welcome. I hope you get one and enjoy it. It's quite the bang for the buck. I got one and didn't tell my wife. She's started commenting how spectacular the picture is even more. Every movie we watch she just says, "Wow"... Skyfall, Avatar, Intouchables and The Hobbit so far. She really appreciated the difference Color Cube and gamma calibrations made but she's even more enthusiastic now. I just let her think it's all the Lumagen/CalMAN/C6 package! smile.gif

Has anyone had problems feeding the Darbee 36-bit deep color source from a bluray player and it blanking out the display ever few seconds or so?

This is a known issue. Turn deep color off. It serves no purpose with any available source material and just gums up the bandwidth with useless interpolated data.

+1.... with no available discs or other readily available content that uses deep color, the deep color option is pointless at this time...You are not getting any benefit by selecting the option in your player. The deep color option is only effective if all parts of the video chain use it.... from camera to authoring to player and display device all together.

No problems running Boxee RGB 36bit color thru darbee and onkyo out.

Thanks for the answers guys, so in summary, Darbee cannot handle 36-bit color depths. Are they going to fix this in the near future and if so, when will that be?

 

Now, as to the setting of 36-bits, that's fine if no image processing is going on in your entire video chain. Yes, your source BD/DVD pixel is recorded at 8-bits. But then, that pixel can be digitally manipulated by the players DSP modes to be greater than 8-bits. Heck, I'm sure even the Darbee algorithms go through basic mathematical computations such as multiplications and divisions which increase the intermediary results to greater than 8 bits.

 

If you multiple an original  8-bit pixel with an 8-bit constant or variable, the end result will always be 16-bits. Truncating or rounding this 16-bit result back to 8-bits(Deep Color Off) could result in severe rounding errors. Now whether these errors are visible or not to the trained/professional eye is not the point at this time.  Hence my preference of choosing to round it off to 10-bits/pixel (30-bits total) or 12-bits(36-bits total) to lessen the resultant errors.

 

Am I missing something here? It seems to me the argument for "Deep Color On" is rather obvious when using the Darbee with its sophisticated image processing algorithms.

On Monday I watched the season 3 premier of Game of Thrones. I was very impressed, it looked significantly better than season 2. But how could that be? Same projector, video data of the same quality as last year.

It just hit me. The difference is the Darbee. I got it last August. This was the first time I had seen Game of Thrones with the Darbee.

It's hit and miss.

My oppo works with deep color in 2d but 3d get blanking.
From my dune base 3d, Xbox 360, all is perfect with deep color.

My mede8er however does not like deep y color with Darbee.

Even some A/V receivers like our not like deep color with Darbee.Pioneer seems to be rock solid.

All you are doing is in essence a color depth "upconversion". You are trusting that your device it taking the 8 bit info and upconverting it correctly... without inducing errors or other artifacts. And very few processors can do this properly, especially in a typical lower cost bluray player. Although if you have an Oppo, that may be a different story! It is comparable to the process of upconverting a DVD image to high def.... Some processors can do it really well, but it still just isn't the same as having that hi-def source(deep color) to begin with. Not to mention you are vastly increasing the data rate that your HDMI cable has to transmit....Just seems to be much more probability of possible problems and errors by forcing this color upconversion compared to a possible slight increase in color what? clarity? smoothness? Even then, you may not be able to see it except on special test patterns.....To me, forcing Deep Color is only worth it with a Deep Color source and that we don't have unless you have a camcorder that does it with your own videos...... What are you using for a processor/bluray player?

I'm using an Oppo BDP-105 with an Anthem D2v processor to the Darbee then to a Pioneer Elite Kuro plasma TV(PRO-151FD). The Anthem is simply a video pass-through path as far as the Oppo is concerned. No video processing goes on in the Anthem. When a BR is 1080p/60, I select a video mode in the anthem set to the same resolution. Same thing for 1080p/24. I use RGB color space as its the most accurate for my plasma.

 

As for problems transmitting deep color, something is fishy here. Most source devices, processors(Darbee included) and HDMI cables are fully HDMI 1.3 compliant which demands error-free passage of 36-bit color video at 1080p resolutions and better. This is a pre-requisite to getting their certificate of compliance(COC) from the HDMI corporation or else they wouldn't be allowed to claim v1.3 compliance. Somebody(HDMI LLC?) is lying here or the test requirements for compliance aren't rigorous enough to ferret out real world errors.

 

I use a 50ft(or is it 60"?) Redmere equalized cable(from Monoprice) at the output of the Darbee to my plasma as the prior thicker, tough-to-bend and expensive cable had problems. Before Darbee was inserted in my system, all seemed fine but now, I get the random dropouts I mentioned earlier. The Darbee and Redmere cable are HDMI 1.4 compliant so I'm at a loss why the dropouts are happening. My anthem and Oppo are v1.3 & v1.4 compliant, respectively.

 

Now to my original question...is the Darbee at fault as some posters indicated and if so, is a software fix on the way?

 

Thanks,

..................................- David

Yes the Darblet can handle 36bit color depths. I've had two Darblets since last fall which have zero issues with 36bit deep color being sent to them. On one Darblet, 444 36 bit Deep color is being sent to it 100% of the time(Everything is run through a DUO and I have the DUO sending out 444 36 bit to the Darblet). Zero issues. The other one has 36 bit deep color being sent to it around 50% of the time(this one sees a mix of RGB, 422 and 444, either 24 bit or 36 bit, since I am not running everything through an external scaler) . Again zero issues. Whether 2D or 3D it has always been fine in my setups with over twenty devices.

Well you certainly have some fantastic equipment going there! And at this point in your troubleshooting, some feedback from Darbee would be welcome I am sure... Have you contacted Larry Pace or anyone at Darbee? Maybe they would agree to send you another unit to try? Unfortunately as noted on this thread many times, the Darblet can be a fickle animal and if one wants to enjoy it's benefits error free, you may have to play by its rules as far as cable length and HDMI settings.. So, in your case, if you disable Deep Color does it eliminate the drop outs? And I know you stated that the RGB colorspace works best for your plasma, but what happens if you use 4:2:2, etc.? There was a known issue with some Darblets changing the output color space to something other than what they originally sent that was supposedly fixed with firmware.... Can you confirm on your Pioneer, that the Darblet is indeed outputting the correct color space?

Nicely played, but I hope she doesn't surf AVSForum, or you're busted. smile.gif Darblet arrived today. Will hook up and do some playing. It's going to feed an Epson 6020 I installed a couple months ago. The 6020 has already impressed the crap out of me, but UMR is going to be in town for a calibration in the next couple of weeks, so between the Darblet and the first calibration, I'm hoping to get even more performance. More later.

I am getting random "reset" maybe once every 2-3 weeks or so on my first-gen (still old FW) darblet. Anyone got this issue?
i.e. it will sometimes reset to "Logo showing on screen, with % set to 100%" and I need to go in menu to turn OFF logo and reset % to 45-50%.

Yup... ongoing bug. Happened to me once.
post #5841 of 7863
My first take on the Darbee is that I like it and appreciate the difference it makes. It is noticeable and subtle, all at the same time. Many people that aren't video-centric probably wouldn't much notice or care whether the Darbee was on or not. (The demo feature will pull some converts though.) For anyone sitting on the Darbee fence, my two cents are to go for it, but keep your expectations in line. If you can appreciate a subtle but real benefit, then you'll appreciate the Darblet.

I'd be grateful for anyone that wants to repost their preferred settings. I know they've been stated before, but at 195 pages and counting on this thread, sifting through to find them all again hasn't been easy, especially using a generic term like "settings" as part of the thread search.

I need to play around much more with the three Pop, Gaming and Hi-Def options to get a better feel for the differences there. Do most of you use those options strictly as the Darblet literature suggests (e.g., they say Full Pop is only for low quality video sources), or do you just ignore the manufacturer's comments, and simply settle on what seems to work best for your room / equipment chain?

Surprisingly, the remote on the new Darblet was DOA. That made the first few minutes of Darblet operation a little choppy. I went from slightly puzzled to fully irritated in about 5 minutes. Once I decided the included remote had to be the problem, I just updated the Harmony, and everything was fine.

Thanks in advance for any settings feedback.

Been awhile since I got mine, but wasn't there an insulator piece between the battery and one of the contacts that had to be removed in the Remote?

Deep color eliminates the dropouts and my Darbee has the latest software fix for the color space issue (Aug 2012 FW). The Pioneer info shows the correct color space and depth I set in the anthem D2v so I know the Darbee doesn't mess with that info.

 

Guess i'll have to contact Darbee for help...

Good call, but nope, slid that tab out before I even plugged in the Darblet. After it didn't work initially, I next took out the battery to make sure polarity was properly aligned. She was just DOA. I'd have completely lost my mind if the Harmony hadn't been sitting there saying "Calm down Bro, just program me."biggrin.gif
post #5846 of 7863
Most of you have probably seen this already, but there is a significantly longer set of instructions and comments from Darbee than those provided in the Quick Start Guide that ships with the Darblet.

Nothing game changing, but I thought it was worth the quick read. The link below is for anyone else that hasn't seen it yet, and wants to take a look.

it works great with the A400, just like it works great with BD players. I use a couple of A400's with both of my Darblets. 2D, 3D, 24 bit, 36 bit, they have all worked fine from my A400's with my Darbee Darblets.

Giving props to the good folks at Darbee. A replacement remote has already shipped. Customer service so fast, you might get whiplash. That's worth a mention here. Thanks Tom.
post #5850 of 7863
I'd like to get some feedback on purchasing a Cobalt vs.a Darblet and I hope I'm not in the wrong thread. I'm using a pretty basic setup with an Epson 8350 projector which is connected to the different sources with a 30' Redmere cable from Monoprice. My sources are an Oppo 95, Xbox, WD TV Live and Bellvu Satellite TV (I'm in Canada) using a Kinivo HDMI 4-1 switch. I don't anticipate any equipment upgrades soon and am not interested in 3D so, if I'm correct, the Cobalt will give me the same benefits minus the 3D, Ethernet, audio return, etc.
Am I correct in these assumptions?
I can save about $80- shipped to Western Canada if I go with the Cobalt but I want to make sure I'll be getting the same benefits as with the Darblet, ,otherwise I'll stick with that.
Thanks in advance for your feedback!
