Is anyone using a Dell U2913WM Monitor with a Mac Pro? Are you having any difficulties with the highest resolution of 2560x1080?
I bought this model monitor for it's unique panoramic design and 21:9 viewing. It worked fine at the highest resolution with my Mac Pro 3.06 GHz Intel Xeon 12-core computer, but then developed inconsistent blurriness in the image detail. The problem goes away with any resolution below 1920x1080, but this stretches the screen image and makes it unusable for my needs. In my troubleshooting I have done all the basics, as well as tested with another Mac Pro and three different DVI cables. My conclusion is that the issue is with the monitor. An AppleCare representative also agrees.
So, why am I posting this question? Well, I spent an hour on the phone with Dell and they state that the issue is with my Mac. It doesn't matter that I have seven Dell monitors in my office run by three different Macs without a problem or that the issue developed within the first week of use, I was still told that I needed to access a Windows machine for troubleshooting before a warranty replacement could be arranged. I would rather pound a nail into my head than deal with another Dell employee on troubleshooting. I plan to purchase another same model unit and return the one that I have under what Dell calls their "easy return" process. In the meantime, I had to at least ask what other Mac users have been experiencing with this model of monitor, mostly out of curiosity.
