I have 4 monitors. I have a dual 23" monitor setup on my front desk, and a dual monitor setup on the back-desk, one of which is a 49" 4K LG TV that I use for digital take-off as an electrical estimator. I have a monitor profile for just one front monitor, another for just the front 2 monitors, one for just the back two monitors, and another for all of the monitors to be on. I can switch back and fort seamlessly between all profiles, with the exeception of switching to the back two monitors. Occasionally, when switching to the back two monitors, the TV screen will just turn blue, nothing will happen on the second back monitor, and the only thing I can think to do is power off the computer and restart it. Which is a huge problem if I am in the middle of something. I switched back and forth between all the other profiles to see if it happens there, too, and they all function flawlessly. But switching to this one, will occasionally glitch out, and make me have to hard reboot my computer. Any ideas?

As requested see debug info below. Let me know if this helps. As a workaround, I found if I don't go directly from the front 2 monitor profile to the back 2 monitor profile directly, but instead, go front 2, then all, and then back 2, it works fine every time so far.
