How to prevent clipped screen edges on my TV, HDMI-connected?
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.
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.
