If the projector/display has usable color and tint controls then it processes in YCbCr and not RGB.

With this in mind then perhaps it is better to output 444 from the Radiance regardless of the magenta issue. At any rate I'll try it and will let you guys know if it still flashes magenta in 444.
This is what I would like clarification on. If DD could fill out my Matrix then we will know. It may be best to send the Darbee 444 and let it output 444 and then let the projector do its thing. But I agree with the idea of using the S&M disc to ferret out the best option.

So guys, for someone with an HDMI splitter, you would use the Darblet between the source (DirecTV HD Box) and the HDMI splitter, and then the signal would go to both displays without a loss of anything, right?

Lumagen spent a lot of time several months ago optimizing their HDMI handshaking especially related to resolution changes. I did a lot of testing for them and the result was fantastic. They got it cleaned up and very tight. With the Darbee in the chain and 422 set it is now messy with the magenta flash. Whether this is more on the Lumagen or Darbee end I couldn't say. All I know is that its clean without the Darbee in the chain.
I am using the Native option on the STB. Yes exactly - changing to a channel that uses a different resolution results in the flash. Changing channels within the same resolution is smooth and very fast.
I do not have this disc, but am curious what the procedure is for using it to test this specifically. Can you explain?

Its on the Spears and Munsil website...here it is: http://www.spearsandmunsil.com/articles/choosingacolorspace.html

Although this says for testing players it also checks the display since it too will convert between color spaces.

Mine has finally hit Aust, hopefully should arrive tomorrow.
post #1986 of 7863
To follow up on my messages from earlier today - I ran the test with 4:4:4 and the magenta flashing on resolution changes still occurs, exactly as with the 4:2:2 setting on the Radiance.

I also took a closer look at the different on test patterns with 4:2:2 vs 4:4:4. This is no question that with my setup 4:2:2 out of the Radiance is much cleaner in the grayscale bars. With 4:4:4 and RGB there is a considerable amount of static dither-like noise in the low level bars. In 4:2:2 it is much cleaner. This reinforces my earlier view that I want to run in 4:2:2.

It well be well worth the wait Frank!!!!..
I just recieved mine back from DarbeeVision yesterday after the firmware upgrade & couldn't be happier,

Darbees Customer support is first Class!!!! smile.gif ,,,

I don't have any of these problems with my Duo. Noise in grey scale is a luminance issue. With the RS1 feeding it 4:2:2 reduces the highest frequency chroma multiburst so the image is a tad less detailed and less saturated. 4:4:4 looks the sharpest in color and luminance patterns. RGB looks very good too but not quite as sharp on an RS1. Chroma multiburst pattern look good though with RGB.

Even better I just missed the post but there is a letter for me to pick up today at 4pm. Finally get to see what all the excitement is about.

422 into the Darblet now worx fine for me with the latest Dablet firmware with both my Radiance 3D & DVDO vps..

Yet to pick up but the darbee doesnt have a left/right and ok button ?
post #1997 of 7863
Mine says software version 2.8.2205

Firmware is right. Mmm
post #1998 of 7863
Well Ive used this unit and Im impressed. Im at 50% and by the slider you can see the difference. I have to say that Im happy with the purchase.

Thanks buddy, I will check tonight.

Johnsmith,

I read your post on the Darbee vision, I currently have an RS40, Do you think it would be noticable difference with my PJ?
It seams from your post that it may not be.
Your imput would be helpfull
Thanks,
Tony
post #2001 of 7863
Still amazed at what the Darblet is doing for my Acer H5360 in 3d. Everything is popping! Tried Toy Story, Megamind, and Born To Be Wild. I use Game setting on 80 for animated and HD at 50 for real life movies.

I played Gladiator on my rs40. Unbelievable with Darblet! Dlp-like pop.
post #2002 of 7863
John,
I guess I will see a differnce on the RS40.
---Also, what settings for the RS40 did you use?

This should not be possible. I cannot believe my eyes. I have a RS40 but that isn't the projector I am most impressed by what the Darblet is doing. It is my lowly Acer H5360 720p dlp projector that I use strictly for 3d. I feel like the Darblet has completely transformed this projector into something I would never have thought was possible.

First of all the obviously low resolution of this pj now is hardly a factor with the significant increase in perceived resolution and detail. It's so much better that it's ridiculous. I put in Coraline and Hugo, both containing extremely detailed images. My jaw dropped to see what the Darblet did to those movies.

Next, a big weakness of dlp's, especially those without a dynamic iris, are the lower light scenes. I'm not talking a fade to black, as nothing can be done about that. The Darblet has somehow managed to make this cheap little dlp look like it's contrast ratio jumped up 3 or 4 times. Scenes that looked flat are now alive and vibrant.

Dlp's already have that "pop" to their image. With the Darlet, prepare for even more "pop". My RS40 now looks even flatter in brighter scenes.

Thanks

So are you saying the image is not good on the RS-40?

Right. You must be a lawyer, asking a question you already knew the answer to, which is the only reason I answered it. smile.gif

There is a two part series in WSR written by Spears on this subject and how to test using various patterns on the S & M disc. Please note that often there will only be a subjective conclusion possible. Different patterns may give different results and pattern evaluation is subjective. That's the truth. For most testing will drive you crazy. We will get many, PLEEZE tell me how to set it for my specific chain, anybody? Testing awhile back, I found changingspaces made little differences provided a specific device could accept it without .extreme obvious to all color errors.

I was wondering if there was any chance in the near future for a Darblet model that is rack- or cabinet-friendly to be released? You know, just your basic rectangular box with all the controls on the front and all the connections in the rear? This current design with the cables coming out both sides would be very awkward to use alongside stacked equipment in a rack cabinet... I would buy one of these in a heartbeat if they were in a proper case, it could then just sit right next to my HDMI switch at the top of my rack cabinet...

When I use my 3009 Onkyo I have all sources going into it than HDMI 1 to Plasma tv and 2 to jvc HD350 Pj. The pj shows 12 bit on the info screen. When I use the darblet after the 3009 it shows 8bit I also tried an HDMI splitter using HDMI 1 out to darblet and than splitter still shows 8bit without darblet or splitter 12 bit. Is this normal . I sent the Darblet in for the firmware update and back still does the same. Really like it though . More pronounced on the pj than plasma . Great service from Larry and no other issues .
post #2010 of 7863
I hadn't used my Darbee with my AT&T U-verse. I watched the Olympics and KC Sporting Soccer last night. WOW, it's really amazing impact on those two live sporting events. After having an HD projector for years...you become blasé' about live events, often critical of the compression or lack of wow factor. The Darbee makes me think back on when I had my first HDTV and watching an NFL game for the first time...Not that it has that magnitude of impact of HD vs SD, but the "wow" is back again. Can't wait for the Chiefs preseason games now.
