720p vs 1080p

The 720p vs 1080p disparities between a high-def TV (HDTV) and a traditional CRT television set is that they have the ability to reproduce the images on the screen at greater resolutions. The resolutions in use today are 720p, 1080i, and 1080p. 720p vs 1080pThese high-definition sets provide greater detail and a smoother and more realistic looking picture. Many consumers want to know about 720p vs 1080p and whether it should matter in their purchasing decision.

However, one of the challenges of the HDTV market is a large number of shoppers do not adequately understand when it is beneficial to purchase a television with a higher resolution (1080p), and when to buy one with a lesser one (720p). In many industries, advertising marketing helps determine buying factors and influences the direction of the technology. Consequently, many buyers wind up shelling out for HDTV sets that have a higher resolutions even when they visually are unable to see the difference between a 720P vs 1080p HDTV.

Having said that, the HDTV marketplace is quickly changing and 720p is slowly and gradually fading from the landscape. The 720p sets continue to be available and can be bought under the right situations. Presently, the existing 720p sets on the market will more likely be more affordable as well as a somewhat cheaper quality than its 1080p counterparts. Due to this, the 720p vs 1080p debate will continue.

720p vs 1080p Resolutions
As far as the technological differences of 720p vs 1080p; 720p is older but nevertheless used today. The HD picture resolution will provide 720 progressive lines of resolution. Progressive signifies the lines show up simultaneously on the screen. The technical standards for 720p are 1280 X 720 lines of resolution while the 1080p specification is 1920 X 1080 progressive lines of resolution. 1080I resolution is 1920 X 1080 interlaced lines of resolution. See the 1080i vs. 1080p page for difference in those two resolutions.

The additional pixels on a screen will theoretically provide for additional fine detail in the image being displayed. In the real-world, you probably won’t have the ability to differentiate in HDTV sets 42 inches or less. If you want to save some money you can easily go for one that has a lower resolution than Full HD 1080p simply because the difference will be minimal, unless you are planning to be sitting really close to the unit. Keep in mind that some manufacturers will also use some cheaper components in these sets. Below are some common questions relating to HDTV resolutions.

720p vs 1080p Questions
What takes place once you supply a 1080i signal to your 720p TV?

The 1080i signal is down converted or scaled to 720p. Almost all current HDTV’s are capable of doing this.

What is the end result when you feed a 1080p signal to 720p television?

Assuming the TV can accept a 1080p signal, it will be scaled to 720p. But that point is important to remember: Several older 1st generations 720p HDTV’s and even some older 1080p models, cannot accept 1080p signals at all. If this happens, you will experience a blank screen. Currently, most new HD TV’s will accept 1080p signals.

What takes place once you supply a 1080i signal to a 1080p TV?

It’s transformed into 1080p without any resolution transformation. Preferably, the 1080i signal is “de-interlaced” for display in 1080p. A number of HDTV’s perform an improved task with this de-interlacing procedure compared to others, but generally the artifacts due to incorrect de-interlacing are difficult for the majority of viewers to identify.

Final Thoughts
The debate about 720p vs 1080p is still alive today but the technological advancements of HDTV will render 720p obsolete in the future. If you are buying a set less than 42 inches in diameter, then 720p may be worth a look. Remember to let your eyes be the judge and approximate the viewing distance you will be using in your home. You will be able to determine if you see any noticeable differences in the signal source of a 720p vs 1080p HDTV.
