I have a retina monitor, but I can see horizonal "pixel" lines on my screen. This occurred soon after I installed Yosemite, then the problem disappeared, now it has reappeared again. Restarting the computer or restarting in safe mode does nothing. How can I fix this issue?
My system details are as follows:
OS X Yosemite, Version 10.10.1 MacBook Pro (Retina, 15-inch, Late 2013) Graphics: Intel Iris Pro 1526 MB
Color LCD: Display Type: Retina LCD Resolution: 2880 x 1800 Retina Retina: Yes Pixel Depth: 32-Bit Color (ARGB8888) Main Display: Yes Mirror: Off Online: Yes Built-In: Yes
