Understanding Gigabyte Motherboard Technical Specifications

Can someone please explain the "maximum resolution" shown against Gigabyte motherboards.  For example:

Z790 AORUS MASTER X
- LGA1700 socket: Support for the 14th, 13th, and 12th Generation Intel® Core™
- Integrated Graphics Processor-Intel® HD Graphics support:
       1x DisplayPort, supporting a maximum resolution of 4096x2304@60 Hz
       * Support for DisplayPort 1.2 version and HDCP 2.3

Z790 AORUS XTREME X
- LGA1700 socket: Support for the 14th, 13th, and 12th Generation Intel® Core™
- 2 x Intel® Thunderbolt™ 4 connectors (USB Type-C® ports), supporting DisplayPort and Thunderbolt™ video outputs and a maximum resolution of 5120x2880@60 Hz with 24 bpp (via single display output)
* Support for DisplayPort 1.4 version and HDCP 2.3

Lets assume the same processor was used with both these boards:
--Intel Core i9 I4900K which has Intel® UHD Graphics 770

My question is: What is it that "restricts" the resolution of any monitor connected to the board?  Is it the version of DisplayPort (1.4 v 1.2) or is it the processor, which in this case has a UHD Graphics 770 capability?

I want to build a system that is capable of running one of the newer 49" UHD 5K monitors, which run at a minimum resolution of 5120 x 1440 @ 60Hz.  I do NOT want to have to use a GPU and only want onboard graphics, so the motherboard is key to doing this. 

So, according to the two motherboard specifications above, only the Z790 AORUS XTREME X would be capable of supporting this monitor without an additional GPU.

Is that correct?

Also, what does this mean on the specification:  "(Graphics specifications may vary depending on CPU support.)"  This seems a little vague!

Hi, thanks for the link to the CPU, but I am aware of the details of that CPU and it is the motherboard restrictions I'm trying to understand, in the area of resolution.

So, the CPU provides the following graphics resolutions:

Max Resolution (HDMI)‡ 4096 x 2160 @ 60Hz
Max Resolution (DP)‡ 7680 x 4320 @ 60Hz
Max Resolution (eDP - Integrated Flat Panel)‡ 5120 x 3200 @ 120Hz

Why do even the latest Gigabyte motherboard specifications show figures that are much less than these and are even lower for some of the boards?

Is this just a feature of Gigabyte motherboards not being very good at supporting the latest HDMI, Displayport or Thunderbolt 4 specifications as I'm assuming it is these aspects of the motherboard that are throttling their graphics capabilities, since the CPU is MUCH more capable?

Greetings,
The native resolution of the monitor will determine the maximum resolution that can be displayed in this case.

The chipset can support up to 5120 x 2880 @ 60Hz.  Whatever the monitors native is will be what the 790 chipset will display.
