@iPhone2019 "Can we expect smaller bezels..."
Hmmm.
The current Studio Display has a screen panel retaining adhesive strip with a width of 4.5mm + 1mm aluminium case thickness.
The screen panel has a weight of more than 2.6Kgs, and an edge construction robustness to carry such a distributed weight. There is no interior space between the panel edge and the adhesive strip backing.
Inside the panel, behind the glass are many layers of quantum dot etched plastic plastic light pipe and diffuser layers, each which must be held stretched and supported only by the edge fixings.
Keeping all these layer in precise 'quantum dot' position means the edge of the back support to the panel can not really be much thinner than it already is - which is about half the edge thickness of the 5K iMac panel.
The 13"/14"-16" MPB's screen bezels are so tiny because the whole construction of the screen is encapsulated in a glued unopenable structure, with no electronics except the minature backlight LEDs in the structure.
Also the glass/plastic front laminate is an order of magnitude thinner than the much larger glass of the Studio Display.
The Studio display has a PSU, logic boards and speakers behind the screen, and the whole lot can't be shrunk and encapsulated, and retain enough strength to support 2.6+Kgs..
So no. Apple can't reduce the size of the bezels by very much.
Greater than 60Hz panels will come, but so far at 5K+ they are conspicuous by their absence.
Until Apple pays for the screen panel industry to up their game and focus on greater than 4K 'gaming' panels, everything changes 'really slowly'... 😶
