There have been rumors of an iMac with Retina 8K display. It’s coming, but don’t look for it until 2020. Japan wants to broadcast the 2020 Olympics in 8K, and the industry is likely to use this as an opportunity to drive sales of 8K smart TVs. That would prove a good time to introduce an 8K iMac.
Until then, we’ll just have to make do with the iMac with Retina 5K display. Thankfully, it has the best computer display I’ve ever seen. Juniper Research forecasts that 8K smart TV shipments will grow more than threefold between 2020 and 2021, to reach over 400,000 per annum by the end of the forecast period.
A Retina 4K display has 4096 x 2304 resolution. A 5K display has 5120 x 2880 resolution. An 8K display would have an incredible 7680 x 4320 resolution.
Currently, there’s only one commercially available 8K TV currently on the market (pictured) -- it's from LG and is priced at $133,000) -- so 8K content is a long way from becoming mainstream. In a similar form to 4K, Juniper sees 8K smart TVs emerging first, followed by streaming devices and set-top boxes, making this a drawn out process. Expect Apple to be on the forefront of the process.
