Are there special settings to optimize UE4 to 4K? Please read rest.

My viewport graphics and rendering look bad on my 4K TV but absolutely everything else about my computer, including the Editor itself, look good. My UHD laptop renders viewport beautifully. I go back and forth between my UHD TV and 1080p monitor a lot so I thought the resolution rendering would be seamless as it is with my laptop and desktop, however the graphics are to my great disappointment on the 4K TV. What gives?

Have you figured it out?
