"Input signal out of range, please change to 1920x1080"

@KittanN

You can verify if the Fall Creators Update is the cause of the issue by removing it and checking if the issue is no longer present:

Unfortunately I am unable to roll back the update, as after the update Windows said that space was running low on C:/ drive which in fact it wasn't, and I should have checked it before doing anything. So I clicked on the info and it gave pretty much as the biggest (8gb) worth of files as "Old Windows" and I made the mistake of choosing that to free up the space. Therefore I was only able to try Fresh Start, but that comes with the problem of updating Windows automatically to the Creator's Update before me being able to even access Windows.

To that end, I am quite certain that I have exhausted all other possibilities that I can think of, with drivers, reinstalls, adjusting and checking settings etc, as nothing else changed between two play times than what the update brought on. I do acknowledge, that I can't verify it to a 100% because I can't rollback, but I do think that I have done extensively everything else possible so far. I also scoured the internet for similar issues and I found one on BF1, which was fixed by adjusting the settings manually which didn't work for me, and one for Sims 4 and nothing from those fixes worked either. Neither have any other internet provided fixes worked that I could find on the issue on Google. 

Though I can do a clean install of the previous version from the link you provided, I would like to not have to go through it. Of course, if it is mandatory and no other way helps, I'll then go through that in hopes it will work.

Also, this problem doesn't occur with any other game than Battlefield 1. Every other game I have tried has worked perfectly.

I tried a clean boot and unfortunately yes, yes it does. I also tried all other resolutions and refresh rates that come with them and apart from 1 or 2 weird resolutions I could have any combination without an error, except of course my monitor's native 1920x1080 with the 59.94hz.

And furthermore what bugs me is that I can manually change the setting to 59.999999 and it will work until I edit some video setting and it refreshes it back to 59.949999 and the error returns.

Your monitor shows in your Dxdiag as a generic display. It is probably worthwhile installing the drivers for your displays:

Yeah that was after I disabled them to see if it would help. I reinstalled the drivers from your link and it did not fix the issue, the Signal Input Out of Range error still appears immediately after launching BF1.

@KittanN

Try pressing Alt+Enter or the following command line argument to run the game in Windowed mode.

Right click the game, Game properties, Advanced launch options, add "-w" without the inverted commas, Save.

I fully understand not wanting to reinstall your OS.

I did that and the game works perfectly on windowed mode and even in borderless window mode, fullscreen remains as the issue for some reason.

@KittanN Thank you for the update, hopefully it helps anyone else with your exact setup.
