Hey all, I hope this is the right place to post this question. First, let me give some context. I have a iMac with retina that I absolutely love. I have been gaming via Boot Camp, but find that it is just too much hassle to boot back and forth. So, I'm dusting off my game PC which is a pretty beefy machine. However, am unsure about what to do for a monitor. I love the 5K display on my iMac, but when you run Boot Camp, 4K is the max resolution that Windows can do. And the iMac can't really run games at 4K anyway, so I play at 1440. I have assumed that I am taking advantage of the pixels on the iMac since 1440 is exactly ¼ of 5K. But I am not certain that this is right. The reason that I am asking is that I was assuming that if I get a 4K TV and run at 1080 I will get the same effect, namely 4 pixels for each one the video card is sending. Is there anyone out there who can shed some light on this? Was I deluding myself that games at 1440 on my iMac were taking advantage of the pixels? And am I going to get a better looking game running at 1080 on a 4K than I would a good 1080 monitor? if you're just guessing please don't put your guesses here, I can guess myself, but someone here likely has more technical knowledge about the pixel/resolution relationship that would help me decide on buying or not buying a UHD set. Thanks in advance for your help.
