I'm going to start with the problem statement:

My TV over HDMI cuts edges of the picture.

Obviously, most of these problems I have found in the search, point to the cable... But I don't think this is the case.

Cable: EVOLVEO XXtremeCord 3 meters, direct link to manufacturer web site.

• type: HDMI
  


• version: 2.0b
  


• specifically mentioning
  
  
  • 
    UltraHD resolution support
  
  
  • 
    HDR capability
  
  
  • way too much other information concluding it should be of superior quality
  
  

^^^ The cable IMHO is not the culprit, moving on...

Then, my natural reasoning was either my graphics card is doing it, or more likely the TV itself.

So, the GPUs, my laptop is Dell with service tag HG6D142 (direct link to product page):

• 
  NVIDIA GeForce GTX 1060 with 6GB GDDR5 memory which, Max-Q Design
  ^^^ This, once again, IMHO is not likely the problem. Since you can scroll down on the page, and see to Full Specs, and verify Standard Display Connectors including HDMI 2.0b.


• The integrated GPU I don't use that I know of, none-the-less, Intel i7-7700HQ has Intel HD Graphics 630
  ^^^ this should also not be the problem, but I am stating it, for this question to be complete

^^^ Both of these GPUs should be just fine, but I believe, only the NVIDIA is actually in use for the TV.

The operating systems I use:

• Windows 10 Pro (1903)


• Linux Mint 19.2 Cinnamon

^^^ The picture resolution and refresh rates are the same on both. The only difference is I can enable HDR only on Windows, but this question is not about that.

The TV itself is not exactly Smart as it has only some basic functionality:

• Producer: Changhong
  


• Model range: Chiq
  


• Model name: UHD43E6000ISN (sold out)


• Web site: https://aftersales.changhong.cz/en/
  


• 3x HDMI, no DisplayPort
  

It turned out, there is a setting I have never needed in this TV:

Changhong Chiq UHD43E6000ISN

It was the Aspect Ratio = PTP (Pixel-To-Pixel? Feel free to comment, if you found a link to wiki or something, I did not). Selecting this option instead of 16:9 or Auto, fixed the problem.

Original picture, Aspect Ratio 16:9, cropped

After-Fix picture, Aspect Ratio PTP, not cropped

Hope you find this useful if running to the same problem.

I know you have answered your own question. But in case others don't have the same setting on their TV, but are still getting the image cropped all round, I'll leave this answer.

My TV, an 8 year old Panasonic, has what it calls "Picture Overscan" where a small number of pixels, maybe 20 or so, are cropped off all round. Irritatingly enough, this is often just enough to hide a lot of the task bar in Windows. There is an option on my TV's settings menu to turn this feature off. See https://en.wikipedia.org/wiki/Overscan for more info.
