I've seen this on a number of fourms, the JOG button seems to overheat if the monitor has been on too long. My main issue here is the auto detect display just doesn't work. I use this monitor for work and gaming. So if I've been working, I can't change input using the JOG without unplugging the Display Port each time.
This monitor was bought brand new in October and this is such a pain when it should be hassle free just to switch inputs.
