I just bought a new Dell ST2321L 23inch monitor and I want to set the resolution on my PC to 1920*1080. However, when I go to change the resolution settings on my Windows XP PC, that resolution is not provided as an option. The monitor documentation says in this case I need to update the graphics driver. My driver model is an SiS 651_661FX_741_760_760GX_M661FX_M661MX_M741_M760_M760GX. Where can I get an updated driver (from a safe source), and what is the best way to do the update on the PC. I am not very knowledgeable on how to effectively update drivers.
