JOG Button on Cjg50 27 playing up

[Sebastian-W]

On the 23rd of May I brought this monitor, after about 3 weeks or so the jog button underneath the monitor started to play up, I can turn the monitor on n hold it to turn off OK but no matter what way I press the button the OSD always goes to the left which thankfully is to change source, it didn't bother me to much at first as my pc and console were using HDMI so I sorted out the setting and what not when I 1st got it but now I got a new graphics card and using display port and I want to change some settings on the monitor but I can't.
