This is an important point. I have a pal with an aging 5k imac that he wishes he could use only as a monitor with a new mac mini.
It seems display tech in imac is severely discounted in order to sell the whole thing. And it does seem to break the pricing if you don't see them as different products offering value for different configurations.
Bringing back target mode, or allowing the iMac to act as an external monitor would greatly increase the value of that product.
I can't explain how this pricing makes sense exactly, except that I can only assume Apple will want or need to price this stuff high to help differentiate the build quality in comparison to the collaboration on LG's ultrafine.
I bet somebody could make a business refurbishing those old 5K iMacs into usable monitors. Either yank the panel into a new case w/ a custom board to drive the display, or hack an input into the existing system (maybe with a minimal booting OS).
Either way, that'd be a cool product to see and seems like a decent side hustle to get some $. :)
I recently bought a 2015 27” 5K (5120x2880) iMac core i5 for cheap, put in an SSD, and upped the RAM to 24 GB. It handles everything I can throw at it as a developer (albeit not a game developer, just “full stack” web/java/node/k8s) and the screen is just incredible.
The SSD upgrade is not for the faint hearted, however. I used the iFixit kit with the provided “tools”, and lifting off 27” of extremely expensive and heavy glass that sounded like it might crack at any moment was not exactly fun. Having said that - I would do it again in a heartbeat to get another computer/display like this for the price I paid.
With regards to scaling: I have had zero problems with either my rMBP (since 2013) or this iMac, when in macOS running at high resolution. Zero. As soon as I boot Windows or Linux, however, it’s basically unusable unless I turn the resolution down.
I've got a Planar IX2790 and it's great. Article is spot-on re. scaling -- it's much nicer to look at all day (native 2x scaling) vs. 4k at 1.5x scaling.
Thanks for this idea. The design looks surprisingly like the old cinema display. Actually, apparently they use the same glass from the cinema display but no camera. [1]
It looks like the main concerns on this are around stuck pixels. Have you gone through calibration / QA on yours? [2]
Otherwise, seems like a compelling alternative to the Ultrafine.
I believe the theory that it's 5k iMac panels that Apple rejected. I have a few stuck pixels but I never notice because they're so small. I have a blue stuck-on in the lower-right quadrant and I can't even find it now.
That's $200 more than it costs with the computer built in. Would rather see it more aggressively priced, or at least bring back target mode.
