After careful consideration of my last post on which combination of apple devices to own, I decided to simply get a smaller notebook MBP or MBA (if they refresh it) and to connect it to a larger screen. the larger screen will serve as a 2nd display (mostly for media such as gaming, tv, etc).. but perhaps occasionally reading PDF documents. I haven't owned a tv in a while either. I'm looking at something 28-40 ish. budget 400-700 USD. I've heard there were issues with tvs before due to upscaling issues, but if the tv has a high resolution, it shouldn't matter so much right? what are the pros and cons because it seems that I could get a larger 4k TV for less than same size monitor.
