Use Windows in Clamshell (closed lid) Problem with Refreshrate

Soo,
i Would like to use my Surface Laptop in a Closed Lid mode, but the monitor i have is a 144Hz Refreshrate monitor (2K 144Hz)

As it looks like my Laptop can do Video output up to 120Hz and it works perectly when i do Mirror or Extend screen. (But i Want Clamshell)

And There comes the problem, for the 1st time at switching modes (Mirror Screen, Extend Screen), the refreshrate is automaticly set to 144Hz and i have to manualy change it to 120Hz or lower, and i can only do this at my LAPTOP SCREEN -cause the Monitor is Blank (Does not even get signal) . When i change the refreshrate to 120Hz or less, the monitor would work Perfectly

Soo, for the Clamshell mode the Laptop needs to be closed Right, and at the time i Close the lid, the Refreshrate Output goes automaticly to 144hz - Blank screen

Even in the mode - "Show only on 2" -in Display Settings, the refreshrate is on 144Hz, and i cannot change it.

--->Is it somehow possible to limit or Change the Refreshrate Output up to Max 120Hz?

And yes, i disabled all the Power Saving options to - Do Nothing

Sorry for my English

Changing Aspect Ratio limits refreshrate

When I change my aspect ratio to anything but 4:3 both windows and nvidia control panel limit my refreshrate from 75 to 60Hz. The monitor is iiyama PL2530H over HDMI.

 

Overclocking / Undervolting guide for Vega 56 or 64?

Here's a quick laundry list:

List of software to use for overclocking and testing
Examples:
Wattman (and how to find and use it, like an overview, including profiles)
Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)
