SizeSome mainstream TVs are available in multiple screen sizes, ranging from 43 inches to a head-spinning 98 inches. Top-tier TVs with 65-inch screens now cost below $1,500, and larger 75-inch TVs are available for less than $2,000. Resolution and Refresh RateA TV with a 4K (UHD) screen is the best upgrade option at the moment. A higher refresh rate—120 Hz, specifically—offers fast and smooth onscreen action. Products whose screens have the tech offer more vibrant color and higher brightness than non-QLED rivals.
