I currently have 3 monitors hooked up to my system. Onboard video (NVidia 6150) displays all colors properly on monitor 1, but the 2 monitors that I currently have hooked up to the 450G (both hooked up to the top video output to a 2 way DVI splitter and then through dvi to vga adapters) are showing up in some funky colors. My desktop expanded to monitors 2 and 3 just fine, but monitor 2 is red tinted and mionitor 3 is green tinted. I have th emost current driver form the Matros site. Any tips?

You should be able to adjust the color balance for the card. There will be software on your machine that allows you to set the color balance and other things. Usually there is at least some red However if the red is totally gone then it could be a problem with the cabling/connector between the desktop and the monitor, like a loose pin or wire. It is possible that it may be the monitor that has the red out. So first check your connections and your color balance. If that seems ok then try another monitor before you go further. If a different monitor has the same problem (with different cabling too) then you will know.
1. Onboard video card is either disabled or bad. 2. Cable is bad 3. Monitor is bad.
You can check the last 2 relativly easily by hooking the monitor and cable up to another computer to see if they function. if they don't then first try swapping out the cable (i say this first because its cheaper) then swap out the monitor.
To see if the video card is bad try hooking up a different monitor to the system. If the new monitor is not displaying anything then you most likely will need to put a new video card in the machine.

As i understand from the situation, Please do the following:
1. First confirm that the problem is with the monitor. You can do this by trying this monitor on any other CPU. If the monitor behaves Fine, the problem is with the Video Card (Nvidia in your case). If the monitor behaves the same way on other CPU as well, i recommend taking it to nearest service centre. Please Do Not open monitors yourself (Some CRT's may have a possiblity of electrocuting people because they can store a charge upto 25000 Volts in Capacitors). Better get that serviced by authorised people if it doesnt work on any other computer.
2. If the above monitor just works fine on any other machine, probably the problem lies with Video card adjustment.
Please Right click on an empty place on your desktop and click on Nvidia Control Panel. (or you can go to control panel and try to run the same from there).
you will see that Nvidia's video card utility will open. On the left hand side, you will find (depending on the model) 3 basic options.
1. 3D settings
3. Video & television
Expand the Display option and select "Adjust desktop color settings" on the extreme right on the top, you will find an option of "Restore Defaults." Click on that and close the utility. Check if that has resolved the problem.
If not, please try resetting all the options back to Default on the Video control Panel one by one.
I am hopeful that it will solve your problem.
Feel free to contact me if it doesn't solve. I will try to help you till it does.
simply install another video card or get a card that has two outputs no pc will work with more than two video cards but the best setup is 1 on main board and one in the agp slot . or 1pci and 1 agp then enable them in your display settings :)
