Looking to use the Samsung 65UJ7500 4k UHD display as my new Mac monitor. I am going to power it with my 27" Retina iMac. Now, of course, I am moving from 5k to 4k. Most say the difference will be negligible. I also am not certain how to hide the iMac as its purpose will now only be to power this display. However, I am interested in the gained real estate. I am already using a 27" Apple Cinema Display with my 27" Retina iMac. I can ditch the dual 27" Apple Displays and go with one huge display on my desktop. Just asking for a general opinion. I know it's expensive (though I can get the display at cost), but I think it would be an AWESOME single desktop display. Appreciate, in advance, any opinions you may have to offer.
