So I decided to change the resolution of my desktop to 720p for readability on the couch but leave wmc at 1080p, the native resolution of my TV.  Everything is fine, the TV adjusts properly when I close wmc, but when I launch Netflix in wmc I only get a portion of the image.  It seems that Windows is seeing wmc as closed and adjusting the resolution to 720p but the Netflix stream is not scaled but instead stays at 1080p.  I only tried this once, ran into the problem, and adjusted the resolution back to 1080p.  Has anyone seen this issue? 

You may want to go back to 1080p for the Desktop, and in Personalize/Display set the scale to 125%, so the fonts are bigger.

 You can also zoom web pages, which often have very small fonts, by hold the Ctrl key down, and pressing the "+" key.  Press Ctrl - to zoom out.
