"YOUR system has no multi-monitor support!"

by gaugert / February 23, 2007 8:03 AM PST

I have a Sony PCVRS520. With an ATI 9200SE graphics card I have been using two monitors for several years - one VGA and one DVI. Last
Friday the "No support" message appeared and my DVI port monitor failed. Using the vga port - I can receive video on either of the monitors, so it does not seem to be a monitor failure (unless the cable could fail?). I changed out the video card for another dual head with the same result - vga but no DVI.

To my knowledge the only recent software updates came from MS.

After contact with Sony I have reset the BIOS and deleted and reinstalled the video driver. Still no DVI signal.

As an college instructor I have a need for both monitors. Suggestions and guidance?

I have the exact same issue: 2 monitors, 1 vga & 1 dvi, the DVI is not displaying anything once win is starting to load.
In win i get the same error: 'Your system has no multi monitor support'

Please share how you fixed your problem.

I had such a system to trouble shoot. We reloaded the machine to its stock factory load and it started working. We let it install all the Microsoft updates except any DRIVERS (which are OPTIONAL!!!) and it kept working.

We can only guess the owner was installing more than this.

If updated video drivers caused the problem

And since they pay by the hours, we could have racked up a bill more than the computer was worth.
