> I have mixed feelings when it comes to Dell. I use Dell U2713HM. Initially I got the first revision which had issues with a buzzing sound emitted when displaying a pattern on the screen. It completely died after a few weeks. I got a replacement (third revision) and haven't experienced any problems since. I have the same issue. You got it replaced? When I called Dell they sent me a refurb that had dead pixels and buzzed as well. I sent that right back. My brand new display also had a dead pixel from the start. And actually all you need to do to get that buzzing is to display a lot of text on the screen i.e. Wikipedia or something. It's super annoying when you're working in a quiet environment and all you can hear is BUZZZZZZ. I'm still kicking myself for not going with Eizo because Dell was $100 cheaper. I vowed... Dell, never again.
