Hey, nice to see that it is going on in the CRT section. I would not cut out a tube if not absolutely needed. Tried it once, destroyed the tube. I think your idea to paint the housings is the best. It should be obvious that thoroughly cleaning the housings is very important. If clean, they can be painted with matte black color, i did use the cheapest standard spray paint i had laying around. That was 2 years ago. No problems so far. If you want to make sure that it will last forever.... i'd propose you brush the housing with any epoxy (glue or whatever) and then (spray-)paint it afterwards. That seals the aluminium and you're free to choose any color of epoxy that's available.
It may be good to use stainless screws to prevent from further corrosion. In my opinion, rusting screws contribute a fair amount of yellow / brown to the glycol while aging.
Additional black (engine seal) silicone as a thin layer on the new bellows helps sealing the thing.
Regards, Julian

could anyone send me an EDID-file (bin or dat, prefereably bin) from any digital projector? I'm still having problems with mosaic and i guess that something in my selfmade EDID-files is wrong.

The problem with the Matrox DualHead2go is: there are two versions: Analogue with 1x VGA in and 2 VGA out, max resolution 2560x1024 at 60Hz. Isn't enough for my setup which is 1056x800x60 at the moment, at least 1056x800x120 in the future, hopefully about 2x1408x1440x60 for 2D and 2x1056x800x120 for 3D. The digital version of the DualHead2Go is of no use for me as i have CRT projectors with analogue inputs.
I recently saw that Nvidia offers "Surround" on most GTX cards as well, but you'll need to have two in SLI mode or a dual gpu card (like GTX590 or 690). But since the non Quadro cards don't offer mosaic support, i don't think any driver based blending will be available. The strangest thing of them all is that i only found Surround-setup descriptions for three monitors/ projectors, but not a single one with two.

Well, hello again. First: Mosaic is part of the NVidia driver. Mosaic is available in the NVidia control panel if the driver detects a Quadro (or Tesla) card, but will be disabled if the driver detects a Geforce card. I found some time over the past few days to go on with my setup. Last weeks state (like all these months before): - Nvidia GTX480 BIOS- modded to Quadro 6000 - Nvidia driver , 320 something, did uninstall and clean it after adding the EDID - mosaic partially working - no edid-signal from the projectors - custom resolution added with nvidia control panel (1056*800*60) Recent changes: - i harvested two identical EEPROMs from an old DDR RAM- module and copied the information that was on my Samsung TFT monitors EEPROM. Just read out via Powerstrip and flashed it onto the EEPROMs using a programmer from a friend of mine. - Soldered the EEPROMs to my Marquees DVI cables and reflashed them with a custom EDID- file i created using both AW EDID editor and CRU. - Powerstrip 3.85 full version is necessary to flash the chip, other versions will ask for a special key you can get from the manufacturer. "standard" timings from my post above means that i let nvidia control panel set the porches. I used the "automatic settings" for my 1056*800 resolution This time i calculated the necessary porches using the Marquee's spec sheet by VDC vdcds.com/pdf/datasheets/8110-8500-9500.pdf- Used 0.5 to 1V video signal level instead of standard 0.3 to 0.7 (or similar). Windows 7 and Nvidia control panel don't make problems anymore about resolution changes after reboot of the pc and so on. I can set both projectors together as a large display using mosaic in nv control panel. Windows does recognize it as a display with 2112*800 pixels, which is fine. Using the Marquee remotes *- Button i get the same plausible values (48,xx kHz and 60Hz) on both projectors, which also is great. The only thing that my setup lacks at this point is that Mosaic only allows me to do "frame correction", but not "overlap". Overlap would be necessary to blend the ... well ... what i would want to be the blend zone. Newer drivers: - i tried the newest, version 377.61 does not offer Mosaic at all in the control panel, - the next older one 376.33 does have a Mosaic option, but doesn't apply my settings. I do have my modded GTX480-->Quadro 6000 BIOS at hand. If someone would agree to check it for errors i made when compiling the file, i would be very thankful. The other in my view possible explanation for the mosaic problem is that(especially newer driver versions) check the RAM size of the card. Quadro cards always have more video memory, 6GB in case of the Quadro 6000, whereas my GTX 480 of course still has 1,5GB. What do you think about this? Regards, Julian

Do you use digital inputs on your projectors and what projectors do you use? As far as I've tried it, the hacked GTX480 does a good job on mosaic, but only with the two TFT displays that i've tried. I did not see any option on edge blending on mosaic, just the overlap function. No settings for the brightness/ contrast fade that's needed for the seamless blend. If you could burn me one or two eeproms, that would be great. In my case, i think i can be happy with the gaming performance a GTX480 has to offer. But, if there is need for a change afterwards, it is sure possible to copy the mosaic and IDP/ICP setups and use it on another card. Maybe minor adjustments are needed, but i think there should be no great problems.

The problem is, you need a working Mosaic setup to use IDP and ICP. And Mosaic is only activated in the Geforce driver if your card is recognized as a Quadro. You'll need both, a "Quadro" and the expensive software. I have a fully pinned DVI-I cable, but i have no EEPROMS and no device to program it. So, for me , additional hardware is the complicated solution. But still looking forward to see your solution.

Well, I've bios- modded a GTX480 to a Quadro 6000. This card is able to do a lot, but it is very power-consuming, too. Later cards can be modded as well, but they require an additional resistor-mod as you can read in the eev-blog thread. Refer to the linked comparision guides to verify which Geforce cards have an equivalent Quadro card (same GPU). If soldering SMD resistors is no the problem, you could o with a newer card. I just didn't want to invest more money than what the GTX480 costs (about 30€) for an experiment. But be aware that the card you buy must have two analogue outputs (we're talking about CRT- projectors, aren't we?) Otherwise, if you're using digital inputs on your projectors, you're of course free to choose any card you like and that's affordable to you. Nvidia Mosaic will only work if it receives an EDID- signal from the projectors. I tried Software- EDIDs, but no luck so far. Immersive Display pro and Immersive Calibration Pro are both working very good, i tried both with my setup. Afaik, you'll need both software packages, ICP to setup the edge blending via camera (webcam or a mobile phone with webcam software (e.g. IP Webcam from playstore)). You will also need IDP to run the setup, meaning to apply it at windows startup. I think buying both softwares is a bit expensive and so i'm still looking for a cheaper solution. But: it works good, i recommend testing the trial versions. Regards, Julian

Well, that's interesting. I should have knows before i bought mine. Not that the GTX480 isn't capable of what i need (gaming on the blend included), but there are more energy efficient cards. The Fermi series are real energy consumers. Kepler cards (like yours) are much more efficient and should also be faster. You can possibly mod your card into a Quadro K5000, but it requires soldering SMD resistors. Here's the original thread. I tried two LCD monitors today on Mosaic. That didn't cause any problems with monitor drivers or EDID data, they were recognized and everything worked fine. One connected via DVI-D and one via VGA to DVI adaptor. So it even works with a digital and a analogue monitor/projector. They only must share a common number of lines, meaning i must set both monitors to as an example (some number) x 1024 on both. That's because of the sidde by side arrangement. If it was a bottom-top blend, they both would of course have to use the same vertical pixel number. So the problem stays the same. But I'm going to try implementing a different monitor driver or edid using powerstrip again these days, it appears to override everything. Haven't used it for quiet a while, did that back in the day when nvidia did not offer custom resolutions and sync polarity. Also i think the nvidia control panel and windows display configuration share the same rights. so one is always overriding the others settings. That always caused problems. hoping to use powerstrip as a "master" software here. Regards, Julian

"My GTX760 has 2 analog outputs". Interesting! Can you use both at the same time? What brand is this?

Well, i reread that pdf. Mosaic user guide 2012Page 11 says: I have custom timings (both projectors 1056x800x60p), so this should be well in the requirement. Since the Mosaic "wizard" recognizes those timings automatically, everything should be fine.

Worst case would be to connect an external chip to each Dvi port wihch carries an EDID. Yes Justin, that's exactly what I do. But be aware that everything later than the GTX 400 series only has one DVI port with analogue. The other port on 500 and 600 series cards have 1x DVI-I (analogue+digital) and one DVI-D (digital only).

Hi Justin, these PCI/PCIE Sync Cards are as far as i understand required to syncronize multiple Quadro cards in different PCs. So, if you have a room with say 4 PCs, each with 2 Quadros (connected via sli bracket), you'd need such a sync card for every PC, to sync to the other PCs. Insede one PC, the Quadros are synced via the SLI bridge. That's how you connect 16 projectors and blend them seamlessly to one picture. Again: that's how i understand it. But my scenario is rather easy: i have one PC, one dual DVI "Quadro" and two projectors. They should be "synced" (if they need to at all) by the V-sync signal.Syncing is in my opinion only needed for 3D via shutter glasses. Like they say in your quote: "synccapable GPUs" I only have one GPU, what should it sync to? Don't let them confuse you, this whole thing is rather complex and reading all these pdfs (some of them disagreeing with others) costs me lots of nerves, too. The pdf you linked seems to refer to the newer Quadros only. K/M/P series. Mine was before K (Kepler), it's a plain Quadro 6000, not K6000 or later (M/P). Hi Case. My card is using the original GTX480 BIOS (which is what you refer to as firmware), the only thing changed is the hardware ID. Hardware- wise, the Quadro 6000 and the GXT480 are exactly the same card, which makes the HWID- mod possible in the first place. The only difference is that the Quadro usually comes with more RAM (usually 6GB), while the GTX 480 comes with 1.5GB. Oh, and the GTX uses 480 pixel shaders instead of 448 (Q6k). Well, i will not exclude the possibility that it may be my modded card that's causing the trouble. I found a lot of info about modding those Geforce cards, but nothing about a modded card that was reported to successfully run Mosaic. In that case, there is the possibility to install modded drivers, which are reported to run Mosaic on every card (even untouched Geforce cards). But... i cannot find modded drivers to download.

Hi Case, how do you think this could be ruled out by Immersive Display pro? I am using IDP, but it requires a working Mosaic setup to work. No Gabor, i did not try two LCDs, but will. Often, the simplest ideas are the best.
There should be modified nvidia drivers out there, searched for it, could not find any. Modified in the means of "Mosaic on any Geforce card". Since I'm not sure where my problems come from and since newer drivers don't enable the Mosaic button in the nv system settings. Thanks.

Well yes, found that driver in the Windows library. Installed it, but still a lot of problems. I can choose that resolution i want (or any standard resolution in the list) on both projectors, but every time when i enable Mosaic, the picture gets stretched. Strange, but i'm used to graphics drivers that behave strange. Picture is higher than it should be for the screen. That is set via the projectors geometry menu. Yellow sphere. Mosaic enabled: Mosaic disabled (that's how it should look like)
To be honest, nothing at all changed with the Sony driver.

I found a .inf file for the FW-900 monitor on AVS forum, but i cannot use it. Seems 32 bit only. Could you send me your inf file, please?
