i have a hp pavillion desktop model 4530 with a m50 monitor.i enrolled recently in a local area lan service. during installation of the software i was unable to adjust my screen resolution to a level compatible with the service. my device manager shows i only have a standard pci graphics adapter. will i have to upgrade to make my system compatible with the lan?
what upgrades work best for this application?
