What has changed is that many modern video cards only have one DAC on them, so they can only drive one analog display. If you want to use more than one monitor, only one can be analog; the rest all need to be digital.
As was the case with my HD5770
It's got to be a AMD vs Nvidia driver conflict or something, the 2nd Monitor literally isn't recognized what so ever. Like it's not plugged in.
You can throw away the Nvidia card or you can listen to what we are telling you. The onboard graphics are disabling because they are AMD and the discrete card is Nvidia. It might be possible to force it on, maybe not, that's up to your particular motherboard, not my issue.
Nvidia cards now only have a single analog output. This is normal, as designed. Current AMD cards still support more than one analog output, but this will be changing before long. A few years after that, analog outputs will be removed entirely, since they're not DRM-compliant, by design. The clock is running out for analog.
There are two issues here, the onboard graphics auto-disables when a non-AMD GPU is present. Bummer. Maybe a firmware update for your motherboard will help, maybe not. Impossible to say from where I'm sitting.
The other issue is that you want >1 analog output and those are being phased out aggressively. You can buy an AMD graphics card as a temporary solution. That will enable the onboard and also will have 2 or more analog outputs from the discrete GPU.
Alternately, you can just buy a new display, and kill twenty or thirty birds with one stone. You say you're a graphic artist professionally, but you're using two VGA-only monitors that are 5+ years old? Either you're not nearly as professional as you claim, or you don't know what you're missing.
