I found the answer to my own question when I did some research about my video card. So my notebook can indeed power a monitor of that high a resolution.
My next question is will I notice a big difference in performance? After all, 1680 by 1050 is a big step up from my 1280 by 800 notebook display.
I have an Acer Aspire 2003Lmi notebook that has an ATI Mobility Radeon 9200 video card. I am looking into buying a 21" LCD monitor from Gateway that is widescreen and HDTV ready. The monitor I'm looking at has a max resolution of 1680 by 1050, and I'm wondering if my notebook's video card is capable of powering this monitor at its max resolution. I was checking in the Display Settings on my notebook, and under the resolution choices for Display 2, the 1680 by 1050 resolution is available and so are resolutions up to 2048 by 1536. This seems a bit too good to be true to me. Is this possible?
