I tried it on a monitor as well as a different TV than the one it was originally connected to (an older Westinghouse one). It worked in both cases.
Since I didn't have much on the computer anyway other than some Movie apps, I decided to reinstall Windows 10 and it's now 1803. I don't recall whether I did anything driver related or some other settings.
So far it hasn't prompted the 1903 offer yet. Maybe I'll wait till it does and try accepting 1903 again after this fresh reinstall to "recreate the scenario" as close as possible and see if it happens again.
This is what I found out prior to reinstall.

Build 1903

win + ctrl + shift + b
*Beep*
And it look like it reset the HDMI connection or something because an "HDMI 1080p 60Hz" popup appears briefly.

Graphics:
Intel HD Driver 9.17.10.4459 (it says that's the latest driver upon "update attempt")
