Own a Macbook Pro (mid 2010, 15", 2.4 GHz i5 running 10.6.8) and just bought an NEC PA271W display. I have it connected with a Startech
mini Displayport to Displayport cord. At 1920x1080, 60hz, everything displays fine on the PA271W. If I change the display on the PA271W to 2048x1152, 60hz or 2560x1440, 60 hz the screen starts flashing horizontal bars of noise all over the display. I don't know much about these things but it seems like a refresh rate problem.
Should it be possible to make full use of the high resolution capability of this display using my laptop and the displayport cord?
Thanks for any assistance you might be able to provide.
