I'm trying to plug in a 2nd monitor to my iMac at work

and as I plug it in, my mouse begins to lag like crazy and the 2nd monitor doesnt even detect that its pluged in

I've tryed changing power plugs, cables etc but still have the same problem,

I also tryed updating to 10.6.8 but I still get the same problem!


The stupid thing is only 6 months ago I had this EXACT setup fully working

(same monitor and everything)


The 2nd monitor is a Dell P2210

I'm using a Mini display to VGA converter

(which is the same cable I used before)


Is there a bug I should know about with ATI graphics? (its a ATI Radeon HD 4850)


Hope someone can help!

cause I'm outta ideas

iMac, Mac OS X (10.6.8)
