i5/i7 1135g7 (most popular) - Intel Iris Xe Graphics don't support 144hz

[johntawm]

Problem

I have i5 1135g7 and same for i7 version, doesn't support 2560 x 1440 @ 144Hz

These are most popular CPUs on the market and I have HDMI 2.0, which does support this resolution theoretically, however, the driver doesn't seem to support it. 

Additional Details

Currently using Lenovo Laptop, T14 Gen2, I have looked through many forums and there is no way to set this resolution, it doesn't support it, which is weird because this is one of the most popular intel chips and display combo on the market. 

The display that I'm using is Samsung CHG70 27inch.

I tried installing monitor drivers, graphics drivers, Intel auto driver, reinstalling, using CRU software to set custom resolution, troubleshooting on the internet (tried a few possible solutions), none worked.  

This is really disappointing that these issues are not addressed and most users won't be able to raise them or think about them because why would you as a professional spend time on this type of things, it's really important for me that the technology I buy works together and just having this monitor and not work as intended is a huge red flag.

Additional specification from the laptop sheet

What do you think? It's the same for 120hz or any other higher resolution other than 60hz..
