The Apple website states that the new 15" MacBook Pro supports four 4K monitors or two 5K monitors. I was wondering if anyone had inquired about using the new LG UltraFine 5K as the main monitor with two of the LG UltraFine 4Ks as side monitors. I was thinking about using that setup on a curved monitor mount. I asked 3 different Apple Store employees on my latest visit -- they didn't have a clue. To be fair, when I mentioned that the default screen scaling is different on the new MacBook Pros, one chimed in that "it's because the screen is brighter" and another corrected her by stating that "it's a wider aspect ratio" so clearly they don't know what they are talking about.
