I've had tsw4 for a few weeks now and really enjoy it, however, there is one issue that I would like to solve if I can as its annoying and I don't ever remember it being an issue on TSW3, I play on a pretty generic 55" smart tv and I can see pixels down the extreme right and the bottom of the screen, curiously some routes are worse than others, is it possible to alter picture size in game?
This may sound too obvious, but have you tried altering the screen size or position in the console settings? Alternatively, look for the overscan settings on your TV.
I remember this being a problem back when I used to play TSW2 and 3 on PS4. Haven’t noticed it on PS5 though (thankfully). My screen size was set correctly back then. I believe it had something to do with the TSW motion blur and went away when I disabled that setting.
