Well the blue gamma does not bother me to much. It looks realy fucking good and I know what that means as I saw a lot of CRT combinations. But a better setup with better horizontal width adjusting also helps. No drifting anymore also helps. And a correct calibration of the colours.
As soon as I have a problem with bandwidth I will post here so you can show your screenshots of testpictures that you specially made for showing off purpose as you do not watch movies with those boards as you told to me private.

As soon as I have a problem with bandwidth I will post here so you can show your screenshots of testpictures that you specially made for showing off purpose as you do not watch movies with those boards as you told to me private. I think you might have misunderstood something, all my latest screenshots are made running my moddet 02vim, and matching neckboards and moome card at 1080P 72hz 178Mhz. I have postet quite a lot of different pics over time, but none as good as the set im running these days, but i still expect it to get better. I generated a problem on red in the switcher chip on my 03vim miniboard when i was testing some stuff, quite long time ago, so the only moddet vim i have is the 02 with mini board im showing off, and a 03vim who dont have the mini board, and dont have the performance to beat my 02vim. Some time ago i sent you some pics of my 1:1 after i did the flare magnets, and put my GT17 lenses, thats still running. I also told you how i tweaked the flare magnets so the LCP got as sharp as it did. Remember.? Why would i run a setup performing worse than the best i have.? Mr ro co/ steve is the only one who have visited and seen my Marquee in action, your welcome to drop in and have a look to, then ill be happy to go true all the tests and show different set of boards, and you can confirm what boards i have posted screenshots from. If you invite me, i can bring different moome cards and sources show you what that makes of differences to the test pattern and final movie image. Ill try get a hold of a 03 vim with the new mini board and the new moome card mod, who is very much different. Justin told me that his moome now is as clean or cleaner than the reference test generator, who have always beaten up the moome card in all ways. Im quite sure that my new Marquees with new LUG tubes and a high bandwidth videochain will show some different results than we have seen so far. What bandwidth are you running on your screenshots? And do you have the ecrab pattern i posted above.? |

Well you do not watch movies with those exactly the same reason why marquee stopped with the 03 vim. To much noise. I have email from Mike telling me he has a slight difference in light betwee vertical and horizontal because it looks the best because of the noise. More bandwidth will ot be better for you Mike told me numeral times. I can post the email and the skype talk if you need it. What is more interestng is that my other vim slightly modified has perfect bandwidth on blue. How is that possible with the old switcher and ad835? I might post a picture later. I think it shows that the original components can have a very high bandwidth depending on the board that they are on. I mean some have the exact right miller capacitance and turn out to outperform others with the same specs. I found the same thing with my neckboards where I simple selected the high bandwidth boards. No bandwidth modifications but very high bandwidth out of the factory. Why because the design is right but factory tolerances make these differences. Now I could make anothe high bandwidth 02 vim by simple routing green through blue and reroutng the gamma. Might just do that for fun. No sophisticated components needed  |

One other question. How is it possible that you are such an expert when people like mastertech, Gjaky, me and other some with university and others with life long experience in electronica consider themselfs students still?

And beside that. You have a 90 inch screen, much to small. You room is not darkened. You do not know how to calibrate, crushing blacklevels and using an inferior spider to calibrate. I have an i1pro. I know how to calibrate as I was taught by a pro I have a 100 inch screen, still to small. Should I continue? You do not understand peaking as you do not get that is means flattening the frequency responce because of miller capacitance from components and cables. edit: aaaarch the guy makes me write things I really do not want to  |

No it is not personal. It is to warn others that the information tou spread is biassed a lot and you do have to kiss ass with Mike Parker that biasses a lot too. There is no nice way to tell this.

Guess there is only 1 way of finding out, i dont think this is the right forum. ill invite you to a performance thread on AVSFORUM. Your welcome to mention some standard test methods you like me to perform as documentation on the forum. Your at any time welcome to visite me, and ill be happy to go see your setup. |

I have only one important test method and that is that I get involved in the movie that skin looks real as if I can touch it and that sunlight looks like I am outside. No way you get that performance with standard techniques. Certainly not with the potting of dead stuff that covers up cluster fucks  I do not need to prove myself and I have said to much allready. |

Lets get back on a subject. The blue gamma has been removed to increase the bandwidth on blue. Now we have to de focus blue more. So what do we win? More bandwidth makes a sharper image but defocussing makes it very much less sharp. Makes no sense to me but it is a miner issue in the picture.
I will post a picture of the blue on my other vim 1:1 to show that it is possible to get high bandwidth with standard boards. There must be something we can learn from that.

Why do you not replace the chip or try to find the chip? Are you sure it is not just a pin bend like in my case? Or a resistor broken? We could try to help you and together we might identify chips. I do not need that right now but seems you might benefit. i do want to experiment with the Thomson yokes one day thought of that shortly. oh and you say you are now using boards that have even 1:1 if I understand? No noise problems? Do you think it looks better than having a slightly lower bandwidth? |

There is another thing you could try. I did not try it yet but with you 03 vim you could reroute red to blue. Now if you do not have the menu's on blue that would not be so bad. So you could bypass the switch for blue. That might work or not. The thing is that during retrace the CLM send a blacker than black signal to the switcher. So if there is no switcher for blue during retrace strange things might happen. It depends on wht the Moome sends during that time. I intended on using a scope to figure out the retrace video signal and see if it is pure black. If so than it should be possible to bypass the switch completely maybe even use relays for all colour. So if you want pure video you switch to the relais to bypass the switcher Pondering further it is pretty sure that the moome puts black during the porches and the retrace. You might loose blanking on blue. I guess it would be best to do convergence with another vim than use the fixed vim just to compare when setup is done. Spotkill still works and puts the contrast down. |

Its important to run the VIM and neckbords that match, as the gain on the vim has changed from mod to mod, the contrast nr has no importance, just try measure light output at the max setting you can run with no blooming. My contrast is set around 95 with the boards im running, thats 12fl on screen. Its also a good idea to set your moome card to 0-255 when feeding it 16-255, as it will alow you to use the maximum dynamic range of the projector. +1 on this. Everything needs to be matched; just takes one thing to be out of sync for the image to go downhill. His point about increasing the contrast and watching how the SMPTE comes out of black is very important. Linear tracking in this regard (rather than just looking a full blown static SMPTE) in what really provides the overall low end performance and consequent dynamic range. Obtaining that characteristic + max BW+ stability has been the challenge.
MP's new mini board also resolves some blooming issues that have plagued the Marquee when you are looking a 90+ IRE.

I am going to end this debate right here. There is a section in the Lounge for debating performance.
Redfox started this thread so as to document his findings. Anyone else is encouraged to start their own thread with there particular findings.
But debating each other findings is restricted to the lounge thread only.
