For a cinemascope blend with a blend zone you can do:
2048 x 1536 (4:3) interlaced on two TV one c2 units.
In the end you have a blend zone of:
4096 - 3840 = 256
The Cine9 can handle 2048 x 1536@60 Hz progressive. That pre-defined resolution can be found in the Barco setup.

Now thats a nice find! But can you input UHD (to the TVones) at 24/30hz?

Unfortunately not.
You can put 1080p into the scalers which then upscale to 2048 x 1536.
I tried interlaced but it looks not good on my Sony CRT monitor i have here. Switched to progressive and that gave me a very good result.
2 x 9 inch with that resolution gives you 4K cinemascope (upscaled 1080p).

Well, could the two TVOnes be fed with the right left part of a blend separately? Would be easy to generate 1920x1600i - it should fit the 165MHZ limit of the DVI ports, but I doubt the TVone will scale it correctly.

Use a PC, get whatever res you like.
The Cine 9 doesnt have the bandwidth to do 2048x1536. A modded Marquee might go close.

.......2048x1536 interlaced (!) should be no problem with a Cine9. But I did 1600i on my Marquee, but as my seating distance is half screen width - scanlines were distracting. I am looking forward to interlaced reports from you Cine HFQ users, and how much these systems can resolve horizontally.

You can do it progressive easily with a Cine 9, but the bandwidth will limit it, its still sharp, just the vertical 1-1 lines are darker by quite abit.

Interlaced looked always bad for me.
As long as the CRT can handle and lock to high horizontal/vertical rates and looks "sharp" its all good.
1080p@60Hz = 68kHz
800p@60Hz = 51kHz
2048x1536@60Hz = 95,2kHz
3840x2160@60Hz = 132,6kHz
Sure it's over the bandwidth but it will lock.
Any graphic card out there with an analog output that can handle UHD ?

No, max is 2048x1536.
It locks, sure. Its sharp, yes. But the 1-1 is terrible. Its bad enough on 1920x1080.

I tested insane amounts of cards when this was new to me....
After the introduction of a 400mhz ramdac a few years back, nothing was improved anymore as analog dispays died on the market. Some cards are reported to have a RAMDAC of 600 (google), but these people mix pixelclock and RAMDAC. So yes, with 7xx and highend 6xx Nvidia cards the possibility was created for graphic cards to output digital 4k up to a pixelclock of 600 mhz, but the RAM-Digital-(to)-Analog-Converters (RAMDAC) of the graphiccard were not adapted.

I have a GTX 760 and a GTX 650Ti, both state max analog is 2048x1536, max DVI is 2560x1600 i think, and the 760 will do 4096x2160 via its HDMI port, the 650Ti wont.

I have 2 hard drives, with Win 8.1 on each, and when I created 3840x1600 interlaced on one of them the image went blank on me, so now my pj can't get to it (stock parts now) nor my monitor, but fortunately I can access them via the other hard drive. Usually a resolution that's not supported makes the computer snap back to the last working one, only not always! PRobably a user error on my part, but I'm at that point now, and for like the 5th time. With Powerstrip that happened to me all the time, but that was with only one hard drive installed. So the only thing to do now is to install windows again I suppose.
Out off pure luck I got access to it via reduced settings, it was presented to me without actually trying, as in like 640x480 something, and thought Yes I can fix this now, with deleting CRU or changing it back to 1080p, but that didn't work. Not only that, but getting to choose that very option is very difficult with Win 8.1. With VISTA it was very easy with only pressing F8 at start up and you're done. I Googled about it but haven't found the correct procedure on how to do it.

@thewolfman: I got all this stuff in the past too. And that was the reason to switch to an Oppo in combination with a Lumagen scaler.
Hope you get it fixed again.

Thanks, I Googled it again and found a Safe mode procedure now. Even so it sure sounds difficult to do.. but will try and try again. After that I'll bring out the old sledge hammer and just be done with it.

That is a ridiculous procedure!

You are right about that.. but I got it working now. I got it going with safe mode from the working driver, where the option on which one to restart was given, once there I made the necessary changes.
But it's not in perfect order just yet as the monitors optimal resolution is gone. 1920x1200p. At least I know how to do it if it happens again. Thank God for 2 drivers. And one more thing, it wasn't the monitor that got me into safe mode it was the pj that came to the rescue this time. Very strange behaviour my monitor has, if it's not optimal settings it shuts off. I'm going to bash it to pieces when I get a better one.
That cheap Seike 39 inch 4Ki monitor sounds about right for my needs.

The given max analog mode is a relict of analog CRT resolution modes. With a 760 I was able to hit 440mhz RAMDAC. But I have to reconfirm it, as it was not on my PC on my projectors - might have been the resolution before, that was not changed to the 440mhz resolution. Did all my progessive 4k videos pure analog out (limit 400mhz) on far more than a dozen cards, including 7xx series. Interlaced will be a different story that I have to tell.
@thewolfman: You have to use a CRT for your tests. It should have a scan rate of past 130khz, because if Win does not change to interlaced, your monitor needs that scan rate. I recommend starting from UHD/4k with 24/30hz (your CRT should also support this) and then work up to the limit of your graphic cards. My Marquee starts corrrect scanning at 44/45 hz. But I still doubt you get interlaced past 1920 with your card (what do you use?).
I did tests some ATI cards, and their RAMDAC did not go past 330mhz.

RAMDAC is a thing I need to read up on, I don't know much about that I'm afraid. My troubles all started when I tried aome interlaced modes. I'll leave those alone and stick with 1920x1080p and 817p.

Dev. no interlaced on 4xx card past 1920 horizontally. You can choose it, but the card will send out progressive to the display, and most diplays back out then at highrez.
The only way to confirm interlaced is to watch the Win desktop, see if symbol size matches the higer resolution and then check scan rate in the menu of CRT projector/monitor. But save your time....
