In your Windows display options (right click on an empty Desktop area and choose Display), is everything set to Recommended, or have you customized the settings?  If you have things customized, that could be the reason, but if its only 2017 that shows oddly, and the more current years all display properly, you may just want to leave things alone.

In the back of my brain I feel like I remember something about high resolution causing issues last season...I keep all my displays set to the recommended default settings and havent had any issues, but Ive seen others have a similar experience to yours.
