Over the last few days I've been experiencing light to moderate monitor flickering. It usually only lasts for a minute or so and happens once every 15 to 20 minutes. It's most noticeable if I'm on a white screen (if I'm playing a dark video game I can't see it at all really). When it happens the screen flickers to slightly darker shades, back and forth.
I've tried fiddling with the cables to no avail. Every time I think it's gone it just happens again half an hour later. Should I start with replacing the cable? What is the likelihood my entire monitor will need to be replaced? It couldn't possibly be something else unrelated to the monitor, could it?
I'm using a 24' LCD DELL ST2410 (I know Dell is allegedly garbage, so you can spare me on that)
Any help will be appreciated
