Well, for one, it’ll tell us exactly what television settings your set has. Not all Samsung TVs have the same features. Or don’t share the model - it doesn’t matter to me, either way. Just trying to help you out.
Any TV purchased within the past year or two should look pretty good out of the box. If you do find a link to your owner’s manual on Samsung’s site - you might also search for how to do a factory reset on your TV. It might be good to just reset the TV back to it’s original state. You shouldn’t have problems with the writing or display not being clear using the settings that come configured out of the box.
On Xbox One - there is an HDTV setup utility. You can find this on the settings menu under the TV or Display tile (can’t remember the exact name). It’s a pretty good utility and will walk you through getting the best picture for gaming out of your TV. Give it a try and let us know if running through those steps helped at all.
Also - you haven’t mentioned whether these problems only occur in FM5 - or if they are also problems with other games and/or just watching regular TV and/or movies. If this is an FM5-specific issue - you might try uninstalling/reinstalling the game. If this is happening on other game and with TV/movies - then it’s probably a problem with your TV settings.
We have this TV in our bedroom. It’s great for casual TV viewing, as we don’t watch much TV in the bedroom (we like to do other stuff), but if I had a choice (which fortunately I do), I wouldn’t use it for normal TV viewing or gaming, especially with a next-gen console. We use it with a Sky+ box (the non-HD version).
It is HD Ready (720p) not full HD, so sadly I don’t think that there’s any setting tweaks that you can implement to make your viewing experience any better.
