MyCrt, A fellow Titan owner. Thanks for letting us know. Noos figures that you are at 440Mhz RAMDAC.
I have realized that 4K at this present time on most CRT's will be a failure. BUT I am resolved in getting the equipment to do a 4K blend or as close as I can. I need to get a new YA board for my 2nd G90 and I will be almost there.
Human nature will always show more negative reasons vs positive. By the time we get the hardware ready to view a "near" 4K blend, the source material will be available.

@ stridsvognen: Like always very sophisticated thoughts. Especially the technical depth but I also like the idea of clean downscaling UHD to 1080p. (Not the same but a similar positive effect was ) When we did UHD gaming videos for youtube, these set new standards on 1080p displays - as the youtube bitrate for UHD/4k videos is much higher, resulting in an eye candy experience even on youtube.
I a pretty sure that there aren't many that could argue with you about bandwidth limitations/issues, nor could I. But I can say this: Even if my girlfriend can not fully handle (resolve) high-heels, I nevertheless want here to wear some sometimes...
@hal:
If you go for that premium blend, you do not have to worry about output data limitations. Analog is limited on single display 4k, but on a blend you can not hit the limit of an good analog graphic card output! With 440MHZ, you could do a (22)21/9 UHD /4k blend at 3d with ~2000x1600x120hz per projector via analog out, resulting in a total of 3840x1600x120 (without blend zone).
Certainly not fully resolved....

2048 x 1536 @60Hz progressive looks awesome on my Sony CRT Monitor.
Will try on my BR909 to see what visual result i'll get.

Hi,
Just curious if this could be the answer to this topic.
Edge blender that output 1080p to each projector.
Pure Hardware, Simple, Reliable, FlexibleLow Cost, High performance, More competitive, Edge Blending, Warp and Geometry alignment, Image stacking, Active 3D edge blending, Passive 3D e-cinema, 4K Video wall
Here is the link for more info:

For sure we need to try and see how looks, but im quite sure it should be something like running 1920 x 1080P 96hz on a Barco.
I cant emagine that there will happen much else than it will just get softer, and more flat.
After i tested the MP mods with the high bandwidth, it just stand clear to me that we can not get to high bandwidth.
Pushing a already to small bandwidth just makes it less sharp, less dynamic image, as soon as the bandwidth get some headroom it starts to pop, the more headroom the better.
So my point untill other is proved, is that the power of 1:1 pixel mapping and keeping the source bandwidth as low as posible will always be prefered on a standard CRT projector.
As long as we can keep at least 60hz, prefered 72hz for tripling 24hz source.
Blending is only for the few, and looks like a PITA to setup. And you cant make a blend on a 2-2,4m wide screen.
We will benefit from higher bit dept and higher native framerate, just not sure how much downscaling will mess the image up.
There is no scaler who can compete with no scaling.
So what everyone here playing with displaying 4K on a single CRT here is douing is a bit the same as those who in the past tried to push 1080P on a SD speced 7" CRT projector.
I cant see how the outcome should be much different.

Edit: @haireez:
Getting close, but lacks the vertical resolution of 4k. But hope for external processing is now there....
I would prefer to do everything via PC/Software/Drivers, as more resolutions and 3d in various rates becomes possible.

A blend is for > 3m screen width. Just my opinion.

What new colorspace.? Is there a consumer 4K standard.? |
As was already stated, REC2020 is the main proposal for the new consumer UHD standard (not to be confused with 4K, which is a commercial standard of different resolution and color space). I haven't seen a timeline for the solidification of the UHD standard, although I'd imagine it will be sooner rather than later as the industry push to UHD is unquestionably picking up.
| stridsvognen wrote: | | I have a hard time to find out why anyone cares to worry about 4K. |
I take it you've not seen a 4K or UHD display showing natively captured material. The difference from 1080p is quite stark - Samsung's skyline demo material on their 65" UHD LED LCD literally made me feel like I was seeing each city in person. I haven't had such a reaction to a new display tech since I saw my first 9G Kuro, and before that the first time I saw 1080p material on a 1080p display. UHD is going to be a game-changer.
| stridsvognen wrote: | | With CRT we dont need 4K, we dont have screen door effect or anoying square pixels. |
4K/UHD's primary advantage is that it offers more real, resolvable detail than 1080p. SDE and pixel visibility are almost non-issues for most flat panel displays (no one sits nearly close enough to see either). With digital projectors, both issues are solved by suitable seating distances, but one of the exciting by-products of UHD is that it allows closer seating distances without being able to resolve pixel structure. That being said, I sit about 1 SW away from my 147" 2.37:1 screen, and the only time I see my RS55's pixel structure is with high-contrast material (single-pixel transitions from bright to dark like credits). With normal material, the pixels are invisible.
| stridsvognen wrote: | | even many digital projectors are having problems resolving 1080P 24hz right. |
Completely false. I have no idea what would cause you to make such a misinformed statement.

Hi Hog..
You were expected..
Can you post a screenshot of your JVC with the 1:1 from the SMPTE pattern, and explain to me how well it resolves the blu ray resolution.?
And to be sure we are talking about the same thing here, explain your definition of resolution/ resolving.
Ohh and there is another very good thread for that, so we dont need to make that mess in here.
But ill love to argue about the effect of pushing a 4K source into a CRT projector, in this thread.

As were your banal statements about digital projectors. Yawn.

How trite - I see your inability to apply basic logic continues unabated. You made the original statement. I simply pointed out that it was uniformed and not true. The burden of proof lies upon you to define your terms and prove what you said, not for me to define them for you and disprove it.
But we both know that nothing but you normal bloviating will follow with nothing substantive, so I'll just chalk this up in the already sizeable "strids' BS" column and move along.

Thank Hog.. Im sure many appreciate the move along part.
Then we can try stick to what the 4K bandwidth will do to a CRT projector, and what we guess will be the end result.

Wow, you dodged the hell out of that, not even a single attempt to back your BS! Thanks for admitting early that you have no idea what you're talking about on this particular issue - it's so much easier this way 
Funny, that you claim you wanted to stick to "what the 4K bandwidth will do to a CRT" but you for some reason spent most of the quoted post talking about digital projectors.

No problem. It is after all the wish of the thread starter, who happens to be the man i respect most in here.
I expect you to kick it in a thread about digital projectors, so we dont need to mess up this thread..

Hog.. Why not just move along.. And leave it there.
Please move this subject to another thread, i really really dont want to argue this matter in this thread, and piss all over the thread starters wish.

I would recommend that you don't initiate a discussion about digitals in threads that you don't feel a discussion about digitals are appropriate. Hiding behind feigned concern for the OP or staying OT after you do neither is just childish. If you cared about either you wouldn't have started the discussion in the first place.
