    Are you using any kind of test DVD for measuring overscan??
    I suggest using Avia. Dont use Video Essentials as the overscan screen is not centered.
    Setting overscan at less than 5% is a trade off. It becomes very hard to do accurate convergence around the edges. In addition that are many programs / sources that just arent perfectly centered and then you could see electronic info that is supposed to be off the screen.
    FYI, all the templates that Ive seen / used for geometry have been set for 5%. this work very well, as when you adjust the geometry you are also adjusting overscan. It takes a lot of the thinking out of the process.
    Always remember not to keep your geometry patterns (or any other static pattern)on your screen for more than 15 -20 minutes. This can cause burn in.
    Sounds like your well on your way [​IMG]
