I just purchased a Dell U2713HM monitor.
As soon as the monitor is turned on, the internet (both wifi and wired) goes out.
I have tried the following fixes:
1) Changing channels on wifi router.
2) Changing display resolutions. Very low resolutions bring the internet back (on both cable and wifi).
3) Different ways of hooking the display up to my Mac (directly via a Mini-displayport to displayport cable or by first connecting a mini-displayport to regular displayport adapter and then hooking the monitor up to that).
4) Trying to find settings in the monitor's OSD that may account for the strange behavior.
Any and all help is very appreciated.
Thank you very much!
