2407WFP, connected to Mac works fine for 2 seconds
This 2407WFP (b) has worked fine for years as a second monitor for my iMac until recently. Now, it turns off after 2 seconds but it shows the log in screen for those 2 seconds. There is a new 2013 driver on the Dell website but it’s for PC only. I plugged it into my MacBook Pro and it does the same. Now my wife wants to throw it out as trash but I hope it’s fixable as was very expensive and great quality. Any help?
