High winds vs. Privacy fence
I just installed a tall privacy fence/screen that is 12 feet long using 3 4x4 posts set in concrete. How should this hold up against wind?

You didn't tell us where you are located so we're left guessing about the winds you might have. Also, how tall is the fence? It appears to be about 8'. But you've already done the work. Time will tell but I guess it will withstand wind pretty well.
Eventually the 4x4 will rot at ground level due to the concrete keeping the wood wet. In about 10+ years there's a chance the wind or someone leaning against the fence may push over the post/fence.

It's about 7.5 ft above ground with 2.5ft or more sunk in concrete. The dirt surrounding the concrete is mostly hard clay. I live south of Denver Colorado and we get some good gusts from time to time

I have a difficult soil around my house. Once you get below the topsoil it's a saprolite clay. When it's wet it's firm pudding but when dry it's well over 1'000 psi which is stronger than many mortars. In the dry summer months it's useless to attempt digging a post hole and often requires a jack hammer.

Time will tell. A good rule of thumb is 1/3 to 1/2 of fence height is what should be buried. For a 90" fence that is 30 - 45".
