was going well then green light on monitor flicked then came back on

Sorry, but I don't think I'm going to be able to help any further with this one. I've been looking for a manual for your monitor, but have been unable to locate one. If you have one, I suggest that you read through it and see what it says about the monitor configuration for various source inputs, and the relative priority thereof. Depending on how it's configured, some sources will have a higher priority than others, and if a signal is received on such a source then the monitor will switch to that source (even if it's only a temporary switch). I'm only surmising though, I just wish I was able to locate a manual so that I could help you further.

Disconnect all sources apart from your computer and see if that works.

It could also be an internal fault with the monitor. I had that once with a TV, where it wouldn't lock onto the SCART source, even when a signal was present (I did check the source with another TV, using the same cable, and no fault was found). I exchanged the TV for a new one (had only just got it), and it now works perfectly.
