At work we are all USING HP dc7800p desktops (INTEGRATED GRAPHICS) with 17 inch monitors.  I am trying to angle for 22 inch widescreen monitors for everyone, but had a question regarding resolution.  On my PC at home, I have my display set at 1680x1050, but the highest resolution available on our work PC is 1280x1024.  If we were to connect a widescreen monitor, would the PC automatically adjust and detect the native resolution of the new monitor?  I'm just trying to find the most cost effective solution before presenting the request.  The other option is to get an external graphics adaptor and run 2 17 inch monitors, but then we'd need to purchase the adaptor, the second monitor, and a dual monitor stand.Anyone reading this topic may find this helpful: http://www.trustedreviews.com/pcs/review/2008/01/30/HP-Compaq-dc7800p-Ultra-Slim-Desktop/p3.  That computer has no expansion slots.  So, it's rather limited as far as upgrading goes.Yeah, I knew there was no expansion slot, which is why I was looking into the external adaptor.  Also, we are running XP PRO, rather than Vista, so I imagine we wouldn't have the problems the reviewer mentioned.  Also, unless I'm really slow today (which is possible), that review doesn't answer my question regarding whether or not the PC would auto detect the native resolution if we were to upgrade to a 22 inch widescreen monitor.I really can't answer the question regarding the 22 inch monitor.  You might try this: http://h30434.www3.hp.com/psg/Thanks, I'm GOING to post the same question there and see what they say.No response so far from the HP forum.  Anyone else here have any ideas or opinions on my original question?I'm wondering, could you just set your pc to the native resolution?That's what I'm wondering as well, which is why I asked here.  I THINK the computer would auto detect the monitor's native resolution, but I don't want to order 5 new 22 inch monitors only to find out after the fact that it doesn't, and then have to explain that to my boss.  The HP forums were absolutely no help, no one on there ever responded to my question (which was pretty much word for word what I posted here).
