Check the scaling options in the video drivers -one might set to scale and the other not.

I tried all possible scaling options under the NVidia control panel while at 1920x1200 and it still won't scale, it keeps virtualizing the desktop beyond 1280x800.

 

Any other ideas or suggestions are welcome.

 

Thanks 

what are the configuration of your 2 systems?

and the cable you are using, are you on VGA or DVI? cos if you do not have a dual link DVI cable or source, the 3007WFP will default to 1280x800? i read that somewhere, not very sure? 

I'm using a DVI cable, and I've tried the same cable for both systems, the issue persists, also, it's being used always as a single monitor.

 

What I think might be happening is hardware limitiations between the motherboard/video card.

 

the system that the monitor outputs 1920x1200 correctly has an NVidia vid card, as well as an NForce chipset motherboard.

 

The system which won't scale correctly has an NVidia vidcard, and a VIA chipset motherboard.  I think this might limit the vid card's capability to scale output to the monitor correctly.

 

Anyone know if this is a possibility? 

What make and model video card on the system which won't scale correctly?

 

If it has two DVI outputs, have you tried the other one?
