nVIDIA have become really rigid in what you can and cant do with newer drivers, especially where analog is concerned, its a real pain in the arse.

nvidia dropped analogue with the gtx 1080 reference card. they've joined the post analogue revolution...
i am considering a blend currently. if i do, i would choose any one of them later model quadro's listed (used). i have seen some quadro's that have dual dvi-i output. i was thinking of using a dual dvi-i to two dvi-i plugs. then two dvi-i to bnc plugs. then run them straight into the 909's. is this what you're doing Julian?

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).

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. |

you mentioned you are using older drivers. what version of the software are you using? old or new? or is there only one version of the mosaic program?

Let's discuss then what happens when you enable Mosaic? I saw the picture of course, but it would be nice to know what is really happening there: it changes only the pixel scaling, or is it changig the timings? Let's apply a test pattern that shows over/underscan percentages for example and use the raster shift.What if you adjust porches?
Also: initially you said you use custom resolution but at standard timings but the quote from the manual outright say custom timings, just a thought.

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

Its got a HDMI, Display port, and 2x DVI that both have analog. Some of them only have 1 of the DVIs support analog, and ive also seen some cards that had a 15 pin RGB as well as 2x DVI, with one of those that did both analog and digital. |

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 |
