Increasing sharpness and contrast on your projector - Page 6

post #151 of 194
Call one of us and put your order in. We might get them in by weeksend and don't believe that other resellers have them because of their Amazon stores. We will all get them essentially within a day of the same time.

Oh yea. I just don't want to butt in on a black CRASHING discussion. But while you can CRASH a party or a car or even a plane, you can't CRASH the blacks. In video terminology you can CRUSH the blacks. If you put up a gray scale, at the lower stimulus levels you should see a gradient. If the lower stimulus levels merge into one, instead of remaining a gradient, you have CRUSHED the blacks. No crushing and you will see a less darker black above the black at 0 stimulus.

I tried the Darblet and was probably in the "meh" camp. It had some benefit, but definitely something you want to keep under 50%. The price was right and the trial period was a good thing. It worked as advertized on my 60" LCD, but in my HT, I have a Lumagen and it failed unless I switched to output RGB. I could have sent it to Darbie for a firmware upgrade, but opted to return it instead. I'd have kept it if not for the fact that the firmware is not user upgradeable. IMHO, having to return equipment for an upgrade is so "yesterday". I'd have paid a little more to have a microUSB plug in the thing with the ability to update it myself via a download. I think this was very shortsighted on Darbie's part. I'll wait for the next iteration that provides this capability before considering it again.

Now, whether that'll ever happen, especially before 4K support is required, is another story....

Said of course with a smile.gif no business of mine with your personal decision .... but seeing what I have seen in my system..... a couple sayings come to mind once you had gotten to the impact potential level of the Darblet with your "projection" system .....

a. cutting nose off to spite one's face

B. throwing baby out with the bathwater

LOLing at the crash! I was just patiently waiting for someone to say something along those lines. I didnt test to see if the blacks had crashed on the LCD but did notice them to be very visably blacker on program material. Havent tested any good shadow scenes to see if its too much yet since I'm liking the white pop more as time goes by testing it on the 70". I can see my 52" tv in the bedroom from my recliner (25'-30' away) while watching the tv in the living room and the whites are so much whiter with the barblet in play.

I'm begining to like it more even though I dont notice any of the detail that is on their site which shows darblet on/darblet off, like the hair highlights for example. Maybe it will be more pronounced in the theater though if so I'll order another as making whites pop more in the theater isnt needed at all with the stewart 150 microperf. I'm a little sensitive to the perfs/shiny material, I can clearly see the perfs from 16' away on white/light scenes but really needed the gain for 3D so am pleased.

Darbee update. We are expecting to have these back in stock on the 24th. smile.gif

If you will accept an open box unit, opened by Darbeevision at the show to install the latest software, give us a call. You will save a few bucks and we can ship it out tomorrow. We have at least one open box available and maybe two, so don't snooze or you could lose. smile.gif We sold four open box units on Thursday.
post #157 of 194
No more open box available. We may get some more in the future and we will post as to their availabilty so you can save a few bucks.

I am at a friend's house. I brought my Darblet over the try it with his RS-45. As soon as we plug it into the HDMI circuit, we get a loud audible hum through the speakers. This is not a 60 Hz hum; it is a higher frequency than that. We have tried plugging it into multiple outlets on different AC circuits to no avail. I don't have any problem with it in my own system. Any ideas?

You didn't mention if it was connected with an AVR in the chain? Some people have issues with the "audio return channel" with darby connected.

Is there any remedy for this? BTW, it was connected to the HDMI output of an Onkyo 5508 pre/pro. I was able to demo the video effect by shutting off his power amps, but he won't be considering a Darbee if the audio issue isn't solvable.

If you don't need the audio return channel, a work-around is to move the HDMI cable from the Onkyo's "HDMI Out Main" to the "HDMI Out Sub" connector. Alternately you could go into the Onkyo's HDMI menu and turn off the "HDMI Control (RIHD)" feature. That should disable ARC.

Just had my first Darbee experience on my RS45 watching The Avengers and I was impressed! The effect is subtle, but noticeable and significant IMO. It was fun pausing the film and checking out the two demo modes as well as turning it on and off. Well worth it for the price. smile.gif

If you are using a PC for your source put it in picture mode you will get the Darbee improvements without cost.
post #164 of 194
I have no idea what "put it in picture mode" means, but I've not seen anything on the PC (including ffdshow/avisynth scripts) that can do what Darbee does.

Unless there is something wrong with the Darbee, I doubt that the Darbee is the issue. There are a bunch of RS45 owners that have a Darbee in the chain. I am one of them. have used version one and the current software version with an RS45 and no issues. i even have a Lumagen in the same chain and have no issues.

There have been several issues with Onkyo AVR's with different pieces of equipment.

Now I'm going to have to try one of these Darbee's !!

Hopefully I'll fire up mine tonight. At this point however the real world is already starting to look like it lacks sharpness to me.
Every time I go outside the trees look like they need a sharpening enhancement (or maybe my vision is entering old age).

I felt like this, then I got a letter reminding me that my eye test is overdue. smile.gif

I wonder how sharp it will look with my new glasses on. eek.gif

Who did you get to read the letter to you? smile.gif

Good to see you back on the forums Mark, hope your dog is on the mend too.
post #171 of 194
OK, I have mixed feelings about the Darby on a projector that has a 1:1 pixel mapping issue (Viewsonic Pro8200), but have also not yet tried it on the JVC RS-45.
It makes some faces look a bit rougher even at 40%, mostly wrinkly or sweaty faces, or even yucker, both wrinkly and sweaty smile.gif

It does improve some background clarity on some images on the PJ with 1:1 mapping error. I haven't done much watching yet though, will post another update later.
post #172 of 194
HD 40 is aleady too high for me on my rs20. 34 is about my limit, still worthwhile though.
post #173 of 194
How do you get 34?
Mine goes up/down in increments of 5, oh I am assuming you went into the advanced settings?

Anyhow, I noticed the Darby doesn't on average affect textual sharpness much, but mostly applies a clarifying algorithm based on the luminance contrast of opposing colors.
I would almost call this an "object contrast" enhancement rather than a sharpness enhancement, still it's not bad. When it increases the contrast of details, it does slightly increase sharpness as a secondary effect in some cases, but not on all objects if the colors were already fairly contrasty.

I like the Darby, the difference is more significant on some things than others, but overall it is a nice enhancement.

34? I prefer 36D. That D is for Darbee.
post #175 of 194
You turn on fine control in the advanced settings or something like that.

What I find is with the Darlet too high it can give a false impression of the texure on an object. For me that happens with the Darblet set higher than around 35.
post #176 of 194
I truly hope that this isn't a stupid question, but relative to posts 143 & 145 which state that the Darblet won't work in passing a 4K signal through it - does this then also mean that the Darblet won't be able to be used with the new Oppo blu-ray players to be released very soon, when those would be set to their 4K upscaled output capability?
post #177 of 194
The Darblet's band width limit is about 2K. It just won't pass a 4K signal. The new oppo as an unpscaller that will put out a rather soft 4K image but you will need a 4K display to see it. If you have a 4K display, it will have a 4K upscaler already in it so you could just set the Oppo to 1080p 24 or 60 and then send the signal though the Darblet and let the display do the upscaling to 4HD or 4K.


BTW No question is stupid, but alot of otherwise well meaning answers are. smile.gif

I think I want one shipped to Sweden :O

I guess there will be extra tax fees then huh?
post #179 of 194
AV Science, call or email Mike or Craig, will ship one to you. You can't order it on line because the AV Science store site is not set up for outside the US sales. Shipping would be about $25 extra by USPS. Taxes and duties on your end become your responsibility and payable at your end. AV Science does not know the amount and can't advise you thereto.
