Ok, here is 1:1, I did in 720p (good enough):

I performed search before posting, and it didn't find it.

As for Darbee, the bigger the screen, the better the results.

Will post more tomorrow.

Please forgive my ignorance. I own a 55'' GT50, Samsung BR player/HTB (i know iknow), PS3 and Comcast cable box. I don't have an AVR.
I don't have the funds to purchase an AVR and the Darbee. By the sounds of it, the Darbee makes a bigger PQ difference than a AVR would. But will be able to run multiple devices through the Darbee without a reciever? Do HDMI splitters work? or will i lose quality?

Any advice would be great

You need an HDMI switch. I use one with no problems.

I did a search but could not find anything, has any did any real world tests on lag added by it for gaming?

I did a google search one person said he feels more lag, one said he did not notice any, but no actual real world tests yet.

Are others having the green screen effect when using your Darbee in a chain with a PS3 in YCbCr mode? I can mask the issue by changing the PS3's output to RGB, but I feel like I'm sacrificing a good bit of image quality by doing so. I emailed Darbeevision regarding my issue and I was simply instructed to check back later. I have subsequently done so twice via email with no reply. I don't mind using the unit at its less than maximum potential so long as I'm confident a fix is in the works.

Edit - I have the most recent software, but not the "Lumagen Fix" update if it is of any significance.

Ordered mine today and will be testing many things when it arrives, lag being one of them.

I have answered this a couple of times, mostly for those interested in video gaming and audio sync.

Another way to put the answer is this:

The HDMI 1.4 spec demands 165 MHz for 1080p/60fps, or put another way, allows 165,000,000 ops/sec.

Since we pass a (10bit/color channel) pixel to the output within this specification, we are putting pixels (first in, first out) across our circuit with a total latency of 3 microseconds.

The latency is inconsequential for any human factors of perception for image or audio, even for video gaming.

We are now seeing real world feedback that the "Lumagen Fix" also corrects the PS3 issue.

As for "Lumagen Fix" you mean this one?

"Production 031612- A bugfix for HDMI & analog RGB sources that sometimes could cause color to be slightly off due to an incorrect 601/709 conversion. Added an input type (under Input: HDMI Setup: Type) for undoing an rgb->ycbcr conversion error in a source when done with 601 colorspace instead of 709."

Or is something with Darbee?

thanks fat dave for your impressions...sounds like a realistic feel for what the darbee can do, esp. for you system..........

Battleship just looked tremendous with the Darblet going. The better the source the better the effect. Using HD at 55% with a Sony 790 and 1000ES projector jaws were dropping. Combine that with a new Onkyo 5010 and DTS NEO X 11 speaker sound and we had the best of both worlds.

With the Darbee.

So what was the point of getting on the email list if they don't email anyone and just put it as "in stock" on the web site?

Thankfully someone here in this thread (first Bigham16 who mentions 15 hours ago that he just ordered one, and then dpath who commented that the AVS store shows them in stock. Thanks guys!) let the rest of us know.

This is what I have been experiencing. The cable I have is rather poor with lots of macroblocking on fast movement and mosquito noise. The Darblet just seems to make these artefacts much more visible that I have considered switching if off for cable tv unfortunately. Is there a work around this? Or I just have to make do with using it on bluray and my media player?

I believe Mark said he is away for a few days.That might explain it.He is always on top of everything in this forum as well as orders.

Ordered one from you yesterday evening! Looking forward to trying it out.

I called them last night as I was feeling the same way. I was told they only have a handful. People who emailed were supposed to get 1st crack.

I'm waiting for a phone call to confirm I'm on this so called wait list.

We'll see

Here is the official statement from our engineer:

"I am guessing that by "Lumagen Fix", they mean the fix we implemented in software version 2.8.2214 onward, which corrected various "green screen" issues. This patch (present in software version 2.8.2214 onward) fixed a bug in the Darblet's handling of colorspaces under certain conditions (Note 1). While this bug was first triggered by a Lumagen Radiance, it is certainly not specific to the Radiance, nor was it a bug in Lumagen's software. It's a bug that any HDMI device could have potentially triggered in the Darblet. Software version 2.8.2214 and onward fixes this bug in the Darblet.


(Note 1) The Darblet failed to correctly configure its colorspace conversion tables when handling AVI InfoFrames with the C1C0 field set to 00. The C1C0 (Colorimetry) field specifies whether the signal is ITU601, ITU709, or xvYCC. If it is left unspecified, an HDMI device is meant to figure out the colorspace based on other criteria. The Darblet failed to handle that latter case. Most HDMI devices in our lab always specify the Colorimetry, but a few devices (like the Radiance) do not. It probably should be best practice for HDMI devices to always specify the Colorimetry for the sake of robustness, but it is not required by the spec (CEA-861-D)."

Just got a call back from Mike over @ AV Science. Took my order & should have a Darbee shipping out today.

Hmm, let's review...

Other well known company (rep has even commented in this very thread) :

Website said Darplet "usually ships same day".

So, I ordered Sunday. Wednesday comes and no ship. I call. "Oh sorry it's backordered, we should have let you know". I cancel.

I order from AVS. An hour later I get a shipping notice.

Any questions? Bueller?

Thanks for the clarifications.

I'm on 2.8.2214 and didn't see any issues.

Any word from Lumagen or your own engineers re: the magenta flash problem when using the Darblet?

Sorry Mike, but I bought the darblet from solid signal at the same price and should ship out tomorrow or Fri. I did that so that I would not have to pay CA sales tax......I WILL, however, get a replacement bulb from you when it comes time

I saw that yesterday....however I just realized that AVS will not ship to Canada.

Ordered mine from AVS (after being a p.i.t.a. fence sitting skeptic) and received my shipping info about an hour later. Now, as long as it actually ships today, I will feel REALLY good about getting it on Saturday for some long weekend movie watching fun...

Garbage in, garbage out... the Darbee can't process and clean up poor video sources like the more expensive Lumagen devices.

I can tell you it looks great with Verizon FIOS which provides the best HDTV source i've seen. The majority of the channels look excellent on my 142" screen which isn't forgiving for poor video sources.

Nice summary of the different types of transfers and what they can handle. My levels may be slightly higher but I agree completely with the basic progression (well, maybe not the 85% on 3D thing) I've finally accepted the fact that optimizing the Darbee's performance requires tweaking the levels on a per movie basis. I had settled on 45% HD for everything and then popped in Kung Fu Panda and cranked it up to 75%. All I can say is WOW. At least a 20% improvement on an already amazing transfer with no downside I could see. Also watched Flowers of War at 55% (which I find too high for many films) with stunning results.The Darbee appears to be less about helping poor transfers(which is does some) and more about making great transfers look even more impressive.

I'd be curious to hear how many people have decided on a "set and forget" level and how many plan to tweak per movie...

How does this compare to DVDO EDGE ? Better or worse. We watch a lot of SD (International channels) using DISH TV which can't output in Native but only in fixed (480i, 480p, 720p or 1080i). Anyone please?
I Have the DVDO and thinking of buying another (DVDO is $399 and this one is $290 or so?

The Edge is a scaler/switcher and does totally different things. The Darbee is complimentary to the Edge not a subsitute.
