How about instead of releasing a Thunderbolt Display firmware update, Apple releases a 4K Thunderbolt Display instead! :p

As many of you know, the current Thunderbolt technology doesn't support 5K. You'd have to use two Thunderbolt cables to transmit 5K resolution data. Thus why Apple didn't launch a 5K Thunderbolt Display alongside the "iMac with Retina 5K".

It is very possible to build a 5K Thunderbolt display.

The solution is to integrate a GPU into the display, then connect that GPU to the Mac via Thunderbolt. Thunderbolt supports GPUs; it is essentially a PCI Express bus.

The GPU in the display can then privately drive as many pixels as you want, and the performance will be more than adequate since you basically have a PCI express bus equivalent between it and the computer. This way you're not having to send every pixel on the screen to the display 60 times a second.

Apple isn't releasing a 5K Thunderbolt display either because they don't want to, or don't think it will sell.
