[QUOTE="Jimmysb, post: 1935869, member: 416417"] So back to the HDMI issue; the "static" screen only appeared after the Mac had been asleep (which components were asleep - I don't know), and only occasionally, and switching the monitor off then on would remedy the issue. Having the monitor switched off, waking the Mac and switching on the monitor had no issues. As said in the initial post, this never occurred when the same monitor was used with my Win PC or my works Win Laptop, however, on consideration, I am not sure if the same situation occurred, i.e. either them gone to sleep. So thought something from the Mac is (IMHO) a partial contributor, switching off and on the monitor would also suggest a monitor issue. Moving forward, looking through the monitor settings, I notice the monitor display setting were on auto switching (due to how the monitor was used for work/home), I have now set this to HDMI, and the first thing I notice is that the monitor wakes quicker, and currently the issue has not occurred - yet!! My thoughts are when the monitor is wakened on auto, though it is getting the signal to wake, it is not always interpreting it correctly, leading to static, but switching off/on, gets the correct signal and works. With auto off this should not occur, time will tell. [/QUOTE]
