The following solutions are confirmed to not work: IMac boots at very low resolution (screen fell off and cables were pulled out, screen still works but only at 720p) Hey guys, I have a 27in 2013 imac, turned it on today, stuck on 720p for some reason. Q: imac27 late2013 problem stuck on 1280x720 Q: 2560x1440 resolution not available on my new 27" imac Which means, don't waste your time and pass (and this is an easy one to call).Q: How can I set the 27" Imac to have full resolutions not 1280x720 Pass unless you are given a major price reduction, which they are unlikely to do given how far apart you will be. I know of what I speak, I regularly buy and sell tech for our business.
Only way I'd buy this machine is if the price were cut in half. No SSD just kills this machine, as does the price. You can pick up a rock-solid external WD 4TB drive for a hundred bucks, give or take a 4TB WD Passport is currently selling for $119 retail, and that's convenient portable storage and you can likely find it cheaper. (Yes, I know, there are other criteria, but I'm not wasting my time comparing or arguing about tflops, cuda cores, rops, clocks, bus, etc.) A 3 TB hard drive? Who cares. For comparison, the 2017 iMac's GPU scores 13980. Today good cards are doing five times that number. That money would have been much better spent on an SSD. Don't be overly enamored by the RAM it's cheap, and it's unlikely you'll be making full use of the 32 gigs.
And it's not "maxed out," as it lacks the most critical piece: a full-on SSD. A base 2017 27" 5k iMac retails new for $1800, just three hundred more than this used, nearly four-year old machine. However in that same case the media is so much larger it won't fit on a typical iMac SSD anyway. You can devise situations such as editing multi-cam ProRes where the I/O load is much greater, and in that case the Fusion Drive will be a limit. I can't even tell much difference between application launching time or boot time between Fusion Drive and SSD. That further diminishes any possible performance difference from the boot drive, since all the media is external. In most cases professionals use external storage and I have about 100 terabytes of Thunderbolt RAID arrays connected to these systems. That is when editing less than 500GB of H264 material on the internal drive. In terms of real-world video editing performance, there is no major difference attributable to the hard drive. I have tested the video editing performance of the 20 side-by-side many times. I use them all for professional video editing with FCPX. I own a 2013 iMac 27 with 3TB FD, 2015 iMac 27 with 1TB SSD and 2017 iMac 27 with 2TB SSD.
