My HP 2509M has started doing this flickering thing. Sometimes it resolves itself quickly and other times it takes "forever". It usually happens when the display wakes up from sleep mode so I switched it to never going to sleep, wasting a huge amount of electricity but that doesn't always work. I've looked at the drivers, refresh rate etc. Everything says it's working correctly.
Please help. This is what I use for my home business, so my computer gets heavy use.
