The difference between HD and UHD is resolution. HD has a resolution of 1280 x 720 pixels, while UHD has a resolution of 3840 x 2160 pixels. This means that UHD has four times the number of pixels as HD. UHD, also known as 4K, provides a much sharper image than HD, and is becoming increasingly popular in the home entertainment market.
In addition to resolution, UHD also offers a wider range of colors and better contrast than HD. This means that UHD televisions can display more vibrant colors and more subtle shades of color. UHD also offers better brightness and black levels, which can make images appear more realistic. UHD televisions are also more energy efficient than HD televisions, which means that they will save money on electricity in the long run.
