I recently installed a new hard drive on my Dell Vostro 1720 flat panel monitor. I re-installed Windows 7 Pro and it seems to recognize the big monitor as a vga with the highest usable resolution of 1024 x 768. Other available resolutions are 1600 x 1200, 1280 x 1024 and 800 x 600. How can I get 1920 x 1200 resolution. It was available before on the same computer and windows version.
