Fuzzy Text On TV

Santa brought me a 32" Samsung Smart TV as an upgrade to the monitor connected to my Macbook Air, bringing more screen real estate, Netflix, Amazon Video and an extra HDMI port.  But the screen looked "fuzzy" when displayed from the Mac, and it required quite a bit of searching to reveal the most unexpected resolution.  By default the first HDMI port, the one I plugged the Mac into, is called "HDMI 1", and simply renaming it to "PC", which changes the scaling of the source to improve picture quality for attached computers, resolved the issue. 

Wouldn't have guessed that in a million years.
