To begin to understand the differences between these HDTVs, we must first understand what resolution is. If you take a closer look at your television, you will notice that there are thousands of very small dots or very small squares that make up the entire image. That’s called a pixel, the more pixel a TV has, the better the resolution of the whole picture.
HD ready
An HD Ready TV has twice the resolution of a standard definition TV. If an HDTV has the ‘HD Ready’ logo, this means that this HDTV has a resolution of 720p. That is, it has a format of 720 horizontal lines to display.
Advantage
The picture on an HD Ready TV is not noticeably different from a Full HD TV if the TV screen is smaller than 32 inches. An HD Ready TV can still display crisp, clear images from an HD signal and a device that requires an HDTV like your PS3 or Blu-ray player. An HD Ready TV is much cheaper than a Full HD TV.
Disadvantages
Although an HD Ready TV is capable of displaying clear and sharp images from an HD signal, it still cannot display some of the detail that a Full HD TV can display.
Full HD
An HDTV with a ‘Full HD’ logo has a resolution of 1080p, which means that it has a 1080 horizontal line format to display. The images are extremely clear and sharp.
Advantage
A Full HD TV is best when you buy a flat screen TV with a 42-inch or larger screen. It has more pixels, so it has a better picture resolution than an HD Ready TV. It can show details that an HD Ready TV cannot.
Disadvantages
I can’t really think of a huge downside to having a Full HD TV in your home, except for the price. A Full HD TV can be very expensive.
UHDTV
An ultra-high-definition TV or a UHDTV is unheard of these days, but it’s actually being developed at NHK Japan. A UHDTV has 16 times the resolution of an HDTV. It has a resolution of 4320p and higher.
Advantage
If you want a TV with a very large screen, then an Ultra HDTV is the one for you. Its immense size is its advantage over other HDTVs because you will not find an Ultra HDTV of less than 55 inches. Watching movies and TV shows on such large screens is best viewed on an ultra-high definition television.
Disadvantages
One of the downsides of an Ultra HDTV is also its immense size. Due to its massive pixels, there are no UHDTVs that are sold on small screens; makes it impossible to make a small screen TV with such massive pixels. The screen size of an Ultra HDTV is usually 84 inches up to 152 inches or even more. Make sure you have a very large room when planning to buy a UHDTV.
For me, the only differences I see in these HDTVs are their sizes. For me, all HDTVs can deliver clear and sharp images, but only based on their sizes. An HD Ready TV is only better for viewing from 14 ‘to 32’ screens. A Full HD TV is the best to watch whether you want a 42 ‘or up to 55’ TV screen. And an Ultra HDTV is best for very large screens, from 75 ‘to 152’. So it’s really all about the sizes, if you want larger TV screens, go for TVs with more pixels.
