Hello, I was planning to buy a new MacBook Pro and a 4K monitor this summer. However, my MBP 2010 17" is still running fine and I don't need to get a new laptop at least for the time being. In the past, I got a 24" HP monitor. I put it next to my MacBook Pro so that I could use two screens at the same time. I don't have that monitor anymore. The 17" screen is not enough for productivity. I need an external monitor. I was hoping to get a 4K monitor but my laptop does not support it. It supports an external monitor up to 2560x1600. In addition, I heard that there are many compatibility issues with 4K monitors under Windows 10. Not sure if Mac OS and Windows 7 have the scaling issues Windows 10 users are experiencing. I use both Mac OS and Windows 7. In case I want an external monitor, what suggestion do you have? If my laptop could support 4K, I guess getting a Philips 43" monitor could be good as I will not need to scale up the font size of such large monitor. Under Sierra, what are the differences between using a monitor vs. a TV as an external display?
