    How do I use my external monitor

    I paid for a Win 10 upgrade for my Dell Inspiron 6400. First off it wouldn't recognize my laptop as a 64bit computer, which didn't really matter as I have only 2Gb memory anyway. It installed wonderfully quickly and I was able to use my Flatron 24" monitor by just using the fcn/F8 key on my laptop after booting. However, after receiving the 1st update, my Flatron is coming up with an error "Out of Range/88Mhz analog. Geez, I just don't know. Tried all the buttons and can't find the answer. I am using the laptop screen right now.

    In display settings, find your monitor settings and lower frequency down to 60.
