Can you point me out to where I can find the user.cfg?
Yes i probably can, if you dont see it it will probably that some files are hidden and you have to solve that first.
Do as follow; show hidden content or items in menu bar screensettings like in the picture
If you set this
Select from desktop > this computer > users > username > AppData > Local > Packages > Microsoft_8wekyb3d8bbwe > LocalCache, look here to find this file, " UserCfg.Opt" without quotes.
This file can be opened up with a notepad editor if you click on the right mouse button and select to opened with, you get a menu with choice to select with what program to open the file, so here you select “notepad”
Now i see in the specs of your tv that it has hdr10 on board so it support this.
So in the top of the file you have just opened, in the 8th line it says “HDR10” and then followed
by a 0 or 1, now this means for 0 is off and 1 is on
You can try if on turn it to off or vice versa see whats fit best for you
Although where not finished yet i will continue in a New post in The life of a vampire
