For my current Vision 1 setup, can I install VNB P/N:81771-02 on my green P43 fast phosper tube and use VNB P/N: 2-270340-01B on the red and blue LCP tubes? If yes, I would like to try to install them on my Vision 1 tonight. |

I got a lug tube set from Chris and if you look at Curt Palme thread, Greg mentioned that the VDC neckboards work for 9518 LC and resulted in razor sharp picture that he has to defocus on his set.
Can I use P/N: 2-270340-01B to green & red tube and use old neckboard on the blue tube?

Razor sharp is good! Use a higher resolution!!

That's why I'm curious and still waiting for some expert here to advise as to whether the VDC 0340 & old neckboard can be used concurrently.

You can try to mix the 2-270340-01B neckboards with the old one and see if it is works out or not. But don't forget to configure them to the tube you use.

Thanks Gjaky.
Since I'm using a lug tube now, I just need to change the jumper from B to A for the VDC neckboard 0340 right? Just desolder from B & resolder back to A. Or is there anything more to do beside that to use for lug tube?
Secondly, do I need to install the VDC 0340 neckboard G2 wire or it is not required at all for lug tube?

For the LUG you only need to change the jumper setting, no need for separate G2 wire. |

Ive been thinking of trying 2560x1440 @ 48Hz to see how it looks on my Barco, so if you find it extremely sharp you should try the same!

I've not tried it personally as yet but Greg posted in Curt Palme claiming that the new VDC was razor sharp on lug tube with 9518LC projector.
I got the 9518 from Curt too and just installed lug tubes but currently using old Marquee neckboards.

With the release of UHD bluray discs now id expect a possibility will exist to get movies streamed in 2560x1440, which should be possible to use, ive sent 2560x1600 to my Barco and it looked ok, not as razor sharp as 1920x1080 and no content was available so i didnt spend much time on it.

The UHD HDR format is mastered with SMPTE 2084 gamma, wich is impossible to make work just decently on a low output display.. My experience is you need around 60fl/ 200nit to follow the right curve out of black.
The players will have a HDR convertion adjustment but if used to compensate for a to dim display it adds a lot of white clipping.
Thats 1 issue we will have with UHD as it looks.. 2nd non of the CRT projectors have the bandwidth to properly resolve 1080P, and to get a decent motion handeling on 24 hz we need to display at least 72hz, prefered 96hz.
Even that the new style Marquee neckboards on lug tubes can be very very sharp, it is only a horizontal sharpness, like the G90 and the 909, and its very non linear to gain and bandwidth as its suffering from lots of overpeaking.
Then lets say we can tone map the gamma curve using a Radiance Pro.. 5000$ processor..downscale to 1080P 24 4:4:4 .. Will there be a benefit..?
I doubt it as we now lost the advantage of format and display having a matching gamma tracking free of digital manipulation/ processing, i would see a potential benefit on UHD SDR mastered movies and getting the full 1080P color resolution (4:4:4) out of the source without any upsamplings of any kind.. But again what will that help if we dont have a videochain fully capable of reproducing what we already have.
I seen some asking for a HDMI 2.0 Moome card.. And wonder if they actually have a clue what to use that for, or what happens if the player sends UHD HDR to the projector.. Guess how a movie mastered in SMPTE 2084, 1000-10000nit (300-3000fl) will look on a crt that will max out around 10fl/30nit

So with this huge amount of extra light how will blacks look on a UHD HDR capable set? It seems the digital industry is only recently come to terms with real blacks and now they want to push up the brightness 100 times or more.

If you can track the SMPTE 2084 out of black there is no doubt its much more low level information, im not sure why but the movies i compared the blu ray looked as black was clipped and washed out.. Wich i dont understand why as i been playing on a Pioneer plasma so its still not a UHD HDR WCG display, nothing that would not be possible to do with BD. The pics is a SMPTE 2084 measurement on the pioneer with 30 and 60fl the white line is the reference. and with 60fl it tracks pretty ok up to around 70% IRE, and then the HDR convertion compensate from there.   |
