I finally got a good DVI-D cable it appears. (Had 2 bad frmo newegg so I went with cablewarehouse) However, my projector only goes into 1024x768 for any resolution I send it, except 1, that it went into 1280x1024.


My setup is an nvidia fx 5200 card -> DVI-D -> Sharp m20X projector.


I have tried:


1024x576 60hz (the setting I need in the end)

1024x576 72hz

1024x600 60hz

800x600 60hz (Listed as supported for my projector DVI)

720x400 60hz (Listed as supported for my projector DVI)

720x400 72hz (Listed as supported for my projector DVI)

1440x720 60hz

1440x720 72hz


All of these above resolutions were reported as 1024x768 at 60hz on my projector. I have verified that it was really using these each of these resolutions, and not 1024x768 at 60hz.


I also tried 1280x720, and the projector reported this as 1280x1024. (Note my projector is 1024x768 native).


None of the resolutions were ever 16:9, all 4:3.


*Big Note* I am able to get _ever_ one of the tested resolutions working _correctly_ when using a 15pin d-sub (VGA) cable. I know the PJ can do these resolutions. It's just that it won't work over DVI.


Someone mentioned to me that the fx 5200 is very stern on using only the best (or first?) "supported" resolution that is sent to the video card during the "handshake" process. And that the fx 5200 may be scaling any signal it gets internally and thus only sending it 1024x768 at 60hz, or 1280x1024 at 60hz. Is this true? Can it be bypassed?


In general, what knowledge can everyone share, and also confirm is true?


What may I be able to do to get 1024x576 working via DVI? I'd rather not have to use the VGA cable, but that is the only way I have been able to get it to work.
