Hi, I just found this forum and I was hoping someone more knowledgeable than myself could help w/a monitor problem I am having. I have had a Pavillion 520n for several years and just got a new 20" monitor as a present and I cant use the higher resolutions I think bcs the video card is too old or of poor quality. Also screen refreshing has slowed substantially. Does anyone know whether these Pavillions are upgradeable in video and memory?? Any help would be appreciated. Thanks.
