All types of HD are not created the same. You own an HDTV, means you are not really watching high definition videos. There are many factors, which conspire to create image not as good as your TV’s capabilities. So, it is crucial to ensure that you are taking advantage of what your VU HDTV is capable of.
Factors that may constrain your HDTV performance
Getting HD signals
Connection is the first step. Component cables and HDMI can transmit HD quality images. Red, blue, and green are component cables. In addition, there are two more composite cables in red and white colour for audio. Yellow cable is for VCR or Wii but if you use it for anything else then the HD feature will not work as expected.
If you are not sure of which cables connect where then check the manufacturer’s HDTV manual. If your TV does not have HDMI cables then you can buy them very cheap [less than $5].
Next thing is HD signals, which is enabled by all cable and your satellite provider. You will need to call them to activate HD channels or switch to new satellite box or cable. An image on the screen does not mean it is HD. Often HD and SD channels are separated. So, choose which HD channels you require.
HD signals also differ. HDTV may necessarily not display HD videos or HD quality images. For example, the three common sources people watch movies are with –
- DVD – TV or DVD player converts SD signals to 1080p. You see 1920x1080p but detail is constrained by source. DVD video has 345,600p and TV fills it in 2.1 million pixel screen. There the conversion to real HD gets obstructed.
- Streaming movies – Streaming movie services offer highly compressed 720p signal. Compressed HD means data rates are squeezed making it easy to transmit. The effect is soft and noisy image but better than DVD.
- Blu-ray – This is best option and offers highly detailed and pristine image.
The image obtained from your cable operator’s service will not look like Blu-ray but much better than streaming option. So, a lot relies on your provider and HD channels.
Adjust TV’s picture setting to enhance the image, especially if done right. You can certainly get it closer to clarity you wish using your eyes. However, buying a setup disc is far better. These discs cost $20 and helps to ideally dial the precise brightness, contrast and other settings.
All HDTVs have potential to show awesome image quality but ensure you are not constraining your TV with improper installation, signal, and setup.
Changes in technology
When you visit CompareRaja website to compare, you will get to know the current HD models.
HD Ready and Full HD

4K and Full Ultra HD
4K denotes 2160p and Ultra HD goes up to 4320p.
There are several aspects that determine how images look on your TV including TV panel, backlighting technology, engine, and other parts are also important.
