Dell 2407WFP Flickers

[macfanuk]

I've got a Dell 2407WFP Rev A01 and it's been a great monitor, however, it's just started to flicker lightly. I've tried adjusting brightness, set it to 60hz (the only options are 59hz and 60hz), etc but don't know what else to try to stop it doing this.

Does anyone have any ideas?

What about faulty graphics card, try connecting your 2407 to another graphics device...

Try different graphics drivers...

Try different cable/interface...

Thanks for the reply.
I've tried connecting to my laptop via its docking station, I've tried connecting to my PC, both using VGA cable. Will try the DVI one.
