In the Graphics specs for Intel CPUs (such as 11900K, 12900K etc.) there are a number of specifications listed including Max Resolution (by connection) and # of Displays Supported.
I have seen implied in some reviews/comments/replays of these specs that the maximum resolution is for all displays added up --- so a maximum 3 displays with a maximum resolution of 5120x3200 for DisplayPort connection (11900K) would mean that this could be ONE display at a maximum 5120x3200 or THREE identical displays at a maximum of 1700x1066 connected to the DisplayPort, or indeed any combination that added up to 5120x3200.
Q1. Is this implied situation correct, or are they stating this incorrectly and the 11900K GPU can support all three of such DisplayPort displays at 5120x3200 each?
Q2. And how does this maximum get affected by using daisy chaining of DisplayPort connections using DP MultiStream Transport?
In the simplest of terms, the 11th gen processors' graphics engine can support,
- Three simultaneous output streams.
- A maximum of three simultaneous 4K@60Hz displays or two simultaneous 5K@60Hz displays.
- The Multi-Stream Transport (MST) capability,
- Enables up to three displays to be connected to a single DisplayPort output stream.
- Displays can be connected via DisplayPort Daisy-Chaining or using a DisplayPort MST Hub.
- These monitors share the bandwidth of the output stream.
To explain this bandwidth sharing, let's look at an example. Suppose that you have two 4K@60Hz displays. If you connect them to separate output streams, they will each be able to run at the full 60Hz. If you connect them both to a single output stream, however, they will each be able to run at only 30Hz.
Hope this explains it,

It is very important to note from the outset that the resolution depends, in addition to the graphics of the processor, on the speed of the memory modules used and the number of memory channels, which can affect the resolution parameters of such fully finished systems as laptops and tablets.
It's a modern fully perfect form of this
"Resolution support is subject to memory BW (bandwidth) availability."
The IGCC report in the "memory" section contains detailed information about the memory configuration and the memory modules themselves from the SPD.
