This has been widely accepted as fact, but it appears the only source for this claim is Nilay Patel at The Verge who claimed someone from Apple said they were "out of the display business". I've not seen this corroborated, and I'm clinging to any sliver of hope that new Thunderbolt Displays will emerge!There will be no new Cinema Display ... they no longer make displays .. the 5k LG is it
Any explanation is speculation.So what has been holding apple back from release a 4K or 5K apple cinema display to go with the iMac?
But, looking at the situation, there is no technical reason for it. Indeed the opposite is true - Apple has apparently done the technical legwork for LG in the new UltraFine displays. Well-placed sources are suggesting that anyone who delves into a 5K UltraFine will see a treasure trove of Apple design: it's essentially an Apple display in an LG disguise.
Delivering a seamless 5K resolution over Thunderbolt 3 with DisplayPort 1.2 is actually quite tricky and in the LG UltraFine Apple employs some clever tactics to stream two approximately 4K images and stitch them together to make a 5K display. This is why the UltraFine 5K is the only 5K Thunderbolt 3 display on the market - it's not easy to do. DisplayPort 1.3 supports native, single-stream 5K but hasn't hit the market yet. Hopefully iFixit tears it down so we can see what's going on in there. Apparently the engineers at Apple working on the display thought it would become an Apple Thunderbolt Display, and were surprised to realise their work actually ended up in an LG product.
So, if not for technical reasons, what else could explain it?
First, maybe Apple didn't feel comfortable shipping such a 'hacky' product, but had to have something to offer the market, and hence gave LG the IP. It can reasonably be argued that Apple is somewhat uncomfortable with the idea of using multi-stream displays (i.e., stitching together two 4K streams to make a 5K one, rather than having a native, single 5K stream) because the 5K iMac doesn't have a multi-stream display (and is the only single-single stream 5K display on the market!). The iMac uses proprietary internal connectors and timing controllers to avoid having to use a multi-stream technology. This would have come at some cost and engineering effort. So, if Apple prefers single-stream, they might simply have not wanted to make their own 5K Thunderbolt Display until DisplayPort 1.3 comes out.
Second, business. The Thunderbolt Display would have been a tiny volume product by Apple's standards that probably just wasn't profitable anymore. (Personally I think it should have been kept regardless but that's another debate).
Third, engineering capacity. We know that Apple is a functionally-organised operation (there was probably never a group of people who *just* worked on external displays, for instance), and with R&D spending increasing dramatically, the Mac being neglected, ship dates being missed, and what appears to be a growing number of software and hardware issues, Tim Cook just simply cannot afford to have people spending their valuable time on external displays anymore. It sounds crazy in a company the size of Apple, but it's probably true. The LG UltraFines may have been the best balance between 'spend as little time on it as possible' and 'ship something'.
Again, this is just my personal take on it.
