Looking forward to the gamma circuit testing as well.

I hope you have these mods too, Greg, as we had talks about this Before, sure looks like it right now even, and have been for a long time too, but if not, then get them I'm sure they are in short supply. Me? Oh, I am a gooner so I wont even pursue.
No, what I wanted to say is that, and to get it out of my chest - and move on, is that a guy told me with a 100% certanty your name is called Jim, so I Went there in my drunken haze not knowing what to defend myself with at the moment, so I suddenly brought you into it also. Stupid, among other things, but you sure are in the need of an apologee out of me too. So you are as well getting one, and the last one getting one is you, JbMeyer. If you can forgive a drunk, it would mean a lot, but if not I fully understand. But you are right about it all.. I need to own it and I do! So if you could accept an apologee, that would mean a lot to me. But If I Went to far, and beyond reconcile, I will accept any thoughts you have against me.
Ok, that will be my last Word on the matter really, I too need to move on and forgive myself.
Goes withouty saying, I'm semi drunk now and when I saw the Kurt mods in his floor I was glad on his behalf, I hope they are in super order. He spent years pursueing the best there is in mods, but got a lot of trouble in doing so, and sort of earns the right to have these latest mods from Gjaky for free really! I'm saying that because he has flown all over the World setting peoples pj:s up for free!! Not enough reconition can be said about that, I hope he as well takes this as means to move on and me move out of your ways.
I hope I have said enough to be welcome back, but will sure as hell stay out on any technical stuff I have no insight in it anyways.
So, to you all, I was an ass and I own it.
With all respect, Ulf.

Look what i picked up at the post office today..  aren't those really nice looking boards? why don't you put those side by side to the others we've been discussing earlier. |

Just had confirmation from Moome that he is working on a HDMI 2.0 prototype, not sure what its for, so ill try find out, all i know is will be a EXT edition, and he wants to support 4K 30hz, just wonder why he dont stick to HDMI 1.4, and build a 300Mhz capable dac instead.
Anyone have a clue who would want HDMI 2.0, and why.?

HDMI 1.4 supported 4K resolutions, but only at 24 or 30 frames per second. That works fine for movies, but isn’t useful for gaming and many TV broadcasts, which require 50 or 60 fps. Also HDMI 1.4 limited 4K Ultra HD content to 8-bit color, though it is capable of 10 or 12-bit color. HDMI 2.0 fixed all of that because it could handle up to 18 gigabits per second — plenty enough to allow for 12-bit color and video up to 60 frames per second.
There would also be advantages when scaling 4K to 1080p on your CRT projectors/TV’s as well. One would be no chroma subsampling at 4:4:4. Just some thoughts.

MAK But none of that apply to any of the CRT projectors, we have plenty to do just pushing 200Mhz, and the cards already support 1080P 12 bit 4:4:4 We cant run 4K60 or 4K 30, the only thing i can think of is a better analog bandwidt, but that wont help many, as ill guess 99,9% of all CRT projectors struggels with 1080P 60hz, and WCG and HDR is way off limits, and would look terible trying to pass that to the projector. Im thinking there must be something im missing. |

Im thinking there must be something im missing. Well if this were produced in concert with a video processor that would down convert 4K to 1080p with 10-bit color perhaps there would be an advantage. I don't think Lumagen has any plans to do so and based on my experimentation with the 203 outputting 4K at 1080p I'm not a fan. It just seems that in simple terms there's too much digital signal manipulation going on and even if there's an advantage buried somewhere in there it would take a lot of calibration work which is beyond most enthusiasts let along professional calibrators at this point. Well most people don't accept or realize the BW limitations of even the top tier CRT's so don't waste your time being logical;-) |

I did experiment passing 10 bit, without luck, i was using the Hdfury4, and it created some issues.
I doubt we will see any improvements in higher than 8 bit on CRT, as we still have better low level graduation than a 10bit UHD on LG C7 OLED, as long as we keep the videochain as unprocessed as possible, or aware of the compromises we do, the low lightoutput we have dont call for more bit resolution.

Got some more feedback from Moome..
The HDMI 2.0 chipset is better supported and more common today, so easier to use for a new design, he will aim for a 300Mhz capable output, wich will be more than we will ever need, but leave a nice headroom for tweaking and modding in all forseable future.
I surgested he makes a combined design that can be used for the SONY, Marquee and ext solutions, the Sony board is a bit longer than the marquee one, and ill not think anyone would care if the sony card was spaced 10mm out of the back plate to alow for a adaptor plug, if that would be needet.

Now if Lumagen would add a blend function.... That will never happen, but if you look what blend unit you can get for around 5000$ wich is about the start price of a Lumagen Pro, i think there is options. Lumagen would do it if there was a marked, but for the 3 units they potentially would sell, its not worth 15 min of development time to implement. |

I have tried to get him to do that for some time. Or if he could hack the TV-one Blenders software to enable the 256 point gamma scale for the blend zone. TV-one never implimented it. Its mentioned by a TV-One engineer in the TV-One thread over on AVS Forum burried some where in the CRT thread. If that happenes 4k via crt is possible. Nashou |

Nashou 4k is very out of reach no matter how we do it, and good reason is the hole WCG HDR thing going on, wich you would need to convert.. Just ask Justin how that went, even he is shooting a very bright CRT image in comparison to all other CRT setups. Im struggeling holding everything together at 200Mhz, 4K 60hz is around 600Mhz, split on 2 projectors + blend zone and porch timings ill guess something like 2200x2400x60, thats 317Mhz, i can display that, but its just not very well behaved, not even concidering raster ringing. For image quality you would be better off upscaling 1080P to a higher resolution to get a better fill factor on the huge blend screen, and u will have a movie mastered to match the projector, and the scalers these days are super powerfull, and performing much better than i have ever seen before.. Now the 5000$ pricetag on the Lumagen might be a tough one to start with for most of us CRT owners, i been wanting one for a long time, but refuse to buy one yet, as the hole format is in constant flux, and nobody knows how it will end. Would be fun to tweak a blend setup, and your HT was really nice experience.. The best blend setup i ever seen!! |

well id just be 2:35 aspect ratio. So it be 1600x3840. or 1600x1920 . But because of adding a blend zone it be not quite 3840 wide, maybe 3800, or 1900 per PJ. Or maybe I'll go with 4 marquees in quad blend  Nah, too much work ! Nashou |

Or maybe I'll go with 4 marquees in quad blend Nah, too much work ! Nashou Do you run a full 16-9 screen now.? I would hate to loos the full 16-9 format as there is quite a lot of content in that format, even some movies changing format during the movie, like Interstellar. Maybe if you run 8 Marquee in a blend/ stack configuration you would get enought lightoutput so that you only need to compress the HDR ½ as much as with a normal 100" single CRT setup, so you compress from 1000 nit to 100nit, right now 50 nit is a tough one most CRT setups. But after seeing your blend, and having had my hands in a blend setup, it sure would be usefull with a higher resolution, i would stick to upscaled HD SDR content for best result, and try target around 15-18fl. And the scaler needs to be of the very latest generation, like the Lumagen Pro. |
