Good TVs have better blacks and contrast ratios, better detail with motion, Ultra HD resolution, good integrated streaming features, and solid video processing.
A typical good TV has these features as standard: HDMI 2.0a (most recent version of the HDMI standard(, HDCP 2.2 (most recent version of the copy protection standard used over HDMI), 24p content supprot (for that “cinematic” look), OLED screens (better image, lower energy consumption), etc.
Trend: The TV market is moving away from the current 1080p standard and pushing towards Ultra HD (also known as 4K). An Ultra HD picture has four times the number of pixels as its 1080p counterpart.

The second best TV for most people: Vizio M60-C3 (Good image, great value, and lots of inputs)
The TV with best picture quality: LG E6 OLED TV (pricey)
