AoC in the 1366x768 laptop resolution

Hey, first — I'm well aware of other posts containing the same question, but they haven't given me a satisfactory answer, and the one I'd like to ask about is already archived, hence I'll briefly explain my issue here.

I have a 1366x768 laptop, but my AoC is weirdly adjusted to it despite recognising resolution in the settings. The menu is cut from both ends (you can see it's a tighter than it should be), while the in-game view seems to be rather zoomed-in. I've already tried utilising both the UserPatch and Voobly assistance, but it didn't help in a bit.

I came across this link from this sub-reddit from over 3 years ago and followed (I'm pretty sure that successfully) the tips provided on this page, which was about creating custom screen sizes, but all of unfortunate they weren't found by Windows 10 I'm using, which in turn meant that I couldn't set them on my desktop, not to mention in the game itself.

Therefore, I'm raising that same issue yet again. Is there a proper way to fix it? Am I missing something regarding the "downsampling" method? Or maybe there's yet another route?

Thanks in advance, any help is much appreciated!
