Apple is reportedly working on a 7K display called the “Apple Studio Display” which may be a new version of the existing Pro Display XDR or it may be an entire other product.

The current Pro Display XDR has a 32” 6K display, and we expect this one to be a 36” display. The codename for the display is J327, which is the same codename as a display Apple was working on back in July. This display is expected to have the A13 chip which is the same one in iPhone 11 models.
Mark Gurman said that Apple should release many Macs this year, and an external display around half the price of the Pro Display XDR that is more suitable for regular people. We don't know when Apple is supposed to release this, but Apple is holding an event on March 8 which may release a Mac called the Mac Studio, which you can learn more about by clicking here.
The price point will definitely be interesting. While we don't know if this product is ready, or if it will be released on March 8, we do know it is coming.
