The G90 is a light canon and if run as such a tube toaster.. So guess its wise to turn it down, at 11fl on a 90" it should last quite a while.. I seen a Marquee with lug tubes run at candle power for around 1000 hours, and show slight hint of wear on green, and marquee with LCP tubes with 3500 hours with no hint at all.. So i wonder if the fine grained phosfor in the hi res tubes are the main sinner, i would love to see how a G90 with LCP tubes and some better lenses would look like.
Cool to have 2 cinema`s in your home. I know what you have Also agree enjoy the "dark side" correct adjusted, one of the coolest features on a CRT .And you will measure almost every CRT to infinite contrast. That's because tubes shut more or less off.And the max "used/available" contrast around 16000-60000:1 depend on type CRT, adjustments and specifications.
Its very normal that CRT clip black to some degree, and you have to elevate the raster/ black level, and the main reason to use the Marquee instead of the G90 is that its possible to rebuild the analog videochain to work much better with the reference level signal out of the dac, the G90 image looks to me in comparison very washed out, and im sure it has to do with the very very long overly complicated signal path in the G90.. And thats why its wishfull thinking to implement a Marquee alike videochain like what Gjaky is working on, and get the image quality from a Marquee combined with the focus, geometry and deflection system of the G90
There have been tests with G90 compared to newest marquees with different mod at Curt Palme forum, they say the opposite of you statement here.
Could you point me to the thread with those tests; don't recall seeing that on Curt's site. IMO, it's a shame that the G90 signal path is so convoluted because the focus system really is superior and they perform FAR more consistently out of the box than Marquees do. When Kurt set up my PJ back in the fall he spent 40+ hours dialing things in and a big part of that was chasing down issues like HVPS cross talk, testing Sony and Marquee yokes, etc. It took a long time because each change resulted in magnetics and color calibration being redone and evaluated. Then throw in the mix the radiance/HDfury and you see why it becomes an all encompassing task.
No doubt that Kurt can set up Marquee. I know that.But the only way to see if the Marquee is visibly better is with a side by side test, and both would have to be adjusted by persons with knowledge to the same standards/calibration. G90 is much more complex and new tec compared to marquee, That's also why modd have good effect on Marquees. They are not good without mod, my opinion.If someone says a G90 is a walk in the park CRT, then no knowledge about it. Yes you can get a crappy picture on it if you don't know all the different settings and what it do, and how to set it up. But a Marquee will give a less processed picture overall YES.But processing is not always bad if someone feel its better. This also is what you and others feel about a CRT or other tec.What you like about your Marquee can also be not liked by others. You and me or others can say what we like with our setup and adore but can`t say that it is better. We are different. That is just you're or mine or others opinion. About the tread on Curts forum Just look you find it its there. Will take me long time to find this again, when I don't remember the threads name. I don't care about it.Maybe some otter person here know then please post. The poster CMJohnsen
I have both a G90 and a few different Marquee.. Just lost one today.. I did compare the Marquee and the G90 way back before the Marquee was able to perform as it is today, and i do have mods and different dac solutions for the G90..This thread was kind of me picking up on the G90 again to maybe see if it was possible to tweak the videochain using Gjakys mods, and Marquee neckboards in a G90.. I posted about my G90 experiences back then, and sure a lot of people got upset even they had never owned a Marquee, and far from had a clue how to operate one.There is a few wery simple performance parameters on the G90 that is easy demonstrated, and im pretty sure nobody will disagree that it simply have terrible ansi contrast when looking at the image.. It might not be any huge measurable difference on a simple low res ansi pattern, but with hi res movie content im pretty sure if we all sit together looking at the same screen you would pick the same projector.. Now the Marquee is a terrible machine in many ways, and cant say its not performing worse from standard, i think it might.. And even most of the mods for the marquee introduce more problems than it solves.. So having close to 30 Marquee projectors and huge piles of different standard and moddet boards tubes dacs and whatever have shown results from terribl to fantastic.. And a lot in between.. As Justin tells its a tiresome process to trow around boards and find the right combination.. So having both the G90 and the Marquee projectors in the same house, having done them side by side, and having the option to do it again if i desire makes me think its ok to have a opinion about it, and think that people that has not went true the same trouble testing and evaluating both might go do so before they form a final judgment on the matter.You guys know your always welcome to post some killer screenshots from the G90, testpatterns and whatever to demonstrate how well it performs, or to show why you think it is better, or why your G90 is better than all the other G90 projectors out there.. And ill keep up getting mine up running again.
It would actually be quite easy to demonstrate the difference with screenshots.. Here is a example from the last days, where i shot a standard and a moddet marquee netflix streaming running 195Mhz, both are fast setups, the last/ moddet did not focus as well, think the glycol might be getting bad, same comparison is easy made with a G90.. Forget about colors and calibration.. just look at the contrast and detail level.The G90 will do a nice 1:1 pattern, but if you study the pattern closely or if you would scope the signal you would notice a lot of peaking distortion.. Thats just how that is, and a standard Marquee look just as bad when peaked to look the same on pattern, and i dont see any standard CRT that have any decent out of black performance.. You might think its reference, i think its bad, but that dont change that we each like what we like, but at the end of the day i very much doubt you would pick differently than me if looking on the same 2 projectors, the biggest problem is that thae Marquee normaly fails to perform a decent image, and there is a huge pile of options as it feels like there is no 2 the same Marquee, and the G90 is a G90, its like always the same.. So its consistent performance no doubt about that.And i also stated multiple times that if the choise came between the G90 and a good digital, i would most likely go digital.
Yes this G90 is nice, and the setup i got to see when i picked it up as PJ was spot on.
