Dual Monitor Help

Was messing around today and decided to use an old 18" Dell CRT (M992) in a dual-monitor setup with my new 20" Viewsonic LCD (Maybe this combo isnt possible, if so no need to read on =P)

Specs:
Asus A8N SLI Deluxe
FX-55 @ 3.2
2x 1gig Corsair XMS
1 250gig sata WD Cavair
2 250gig sata WD Cavair RAID 0
Audigy 2zs

and an XFX 7800gtx, (Dual DVI)

My existing LCD, (Viewsonic 20") is in the left port if your looking at the comp from the back. I assume that is for your main monitor just because that would be common sense. Anyway I had no problems installing the CRT, I downloaded the drivers from dell.com, and it is properly installed / recognized.

Then I go to my Display Properties > Settings tab and it shows both monitors. I enabled "Extend windows Desktop", and in the advanced tab for my G-card tried all the options, Clone / horizontal / vertical / Dual View. Restarting after each, but I just get a nice black screen on my CRT.

*NOTE* It had been working a week ago when I dismantled our rec room computer to put mine up since im back from school. But I will try it again on my other system after I post this.

If anyone sees a step I left out, or knows something I may have overlooked like setting the monitors to the same rezolution (will try that right now) any and all help is greatly appreciated =).

Thanks

Have you tried switching the sockets and running the CRT alone and used both video socket? If so maybe it could be the CRT problem.

I know exactly what the problem is. :o 

Try adjusting the frequency of the monitor down to something like 60 or 70.

Hmm, monitor works fine, tried switching sockets, and the refresh rate is set at 60hz, but still black.

I just tried adjusting the color settings on it though and it said that it was in "power Save mode" and to access it using the computer. How do I get it out of power save mode?

Also the problem maybe that windows doesn't support it as a secondary display, I googledl my problem and some people said that it is a possibility. I don't know were to find a list of supported ones though (if there is one).

Try buying a poopy PCI video card and running your CRT on that?

I believe my mobo came with a PCI monitor card I never installed, is that what your talking about?

Yes, that PCI card that came with your mobo. Try running your CRT on that.

I've run monitor setups from 1 to 4 monitors on my rig, so I should know what the hell I'm talking about. I prefer to run one monitor on my main card to get better FPS and run another monitor on its own card. I only run dual monitors now, no need for any more than that, for me.

Have you tried switching the resolutions? Maybe the CRT and LCD have different native resolutions, so try adjusting it. Try running both at the same time with 1024x768 @ 60Hz or 1280x1024 @ 60hz, you know it could be that and the graphics is only set to one setting and can only run one resolution and frequency at a time. So try that and see if it fix the problem.

QwertyCopter, hmm, I think you may be on to something, I did just assume that both DVI inputs on my Video Card were working (since it recognised the monitor when I plugged it in) but there is a big difference between it recognising the monitor and actually displaying anything.

I will try my main LCD in the secondary Input when I get home from work.

Oh and thanks again for all the help guys, I have been reading these forums for about a year now and learned so much, so when I needed help with something I knew exactly were to turn. =)
