UHD and FHD
Difference Between UHD and FHD Full High Definition (FHD) is the resolution 1920x1080P. Ultra High Definition (UHD) is the resolution 3840x2160P. What this means is that there are more pixels per inch (PPI) in a UHD TV. This gives a higher resolution on the TV. UHD is used on larger TVs so you can sit closer to the TV and still enjoy a crisp, clear picture. Below is a diagram of the different resolutions, abd remember too 4k refers to 4000 p instead to 3840 in uhd so you can choose the best tv or device with comparing price with technology.
