Hi,
I bought my retina Macbook Pro 15 inch with dedicated graphics on Saturday, However i am noticing horizontal lines on the display. Its only when i am using the larger text resolution (2560x1600) that i notice it. Does screen resolution cause this problem? Has anyone else experienced this problem? Thanks
 
You need to get it fixed under warranty. At 2560x1600 I do not get any lines, not to they appear at any other resolution.

The default 1440x900 that is standard out of the box is actually 2880x1800 that is shrunken by 1/4 so you should be able to run at the lower resolution. Are you using the Iris card or the Nvidia card? It would help the repair people fix the issue.

Do you have an LG or Samsung Display?
I owned 3 LG's and it's the same problem.
 
Just tried that res using Display Menu, runs fine. 2012 15" rMBP with Samsung panel running Yosemite.
 
If its brand new and not operating the way you want/expect. Then definitely take it back and get it exchanged. It doesn't matter if its an LG or samsung display. Its defective.

Getting it replaced soon. Is there a way to predetermine what screen is inside, Maybe a serial number or build week.
