I'm looking to mount a monitor on a wall near to a window. I've been able to identify some studs in a wall, but it looks like they skipped a stud when they got close to a window. The final stud should be about 6" from the edge of the window, but I can't get a stud finder to pick up anything consistent and the old fashioned wall tap test sounds like it's hollow behind where they stud should be. The window appear to have a proper king and jack or framing stud. Am I good to use the king stud for the monitor mount?
The king stud is a full length stud to give rigidity to the jack stud(s). The jack studs are there to support the header over your door or window opening. There is certainly nothing wrong with fastening a monitor to any those studs. Within limits, of course. I mean if you're going to hang The Greatful Dead's sound system from your walls, you might have a problem.
