Many consumers, after they purchase their HDTV assume that everything they will watch on it is in High Definition. Needless to say, many are disappointed when they find out that their VHS videos and analog cable channels many times actually look worse on their new HDTV than they did on their old analog set. There are several reasons for this which are explained in my article: Why Do Analog TV Signals Often Look Worse on an HDTV than on an Analog TV?.
So, after investing a lot of money on an new HDTV, how do you get the High Definition picture everyone is talking about?
To Get High Definition on an HDTV, You Need High Definition Sources
If you have an HDTV, the only way to view true HD is to have true HD sources, such as HD-Satellite, HD-Cable, or, if you have built-in a built-in ATSC tuner - you can use a standard TV antenna to receiver over-the-air HDTV signals if stations in your area are broadcasting in HD.
Other true High Definition sources are Blu-ray Disc or HD-DVD players, and Cable/Satellite HD-DVRs. However, another popular source that provides near-HD quality is a good Upscaling DVD player. For more details, check out two of my articles that address this issue:
DVD Recorders with ATSC or QAM tuners can receive HDTV signals, but they are downconverted to Standard Definition in order to record onto DVD, and the DVD recorder does not pass the HDTV signal directly from its tuner through to the TV. For more details on this, read my article on this issue:
High Definition vs Non-High Definition Video Sources
If you are interested in getting the most from your HDTV, you need have one or more of the following High Definition sources connected to your TV:
1. HD-Cable, HD-Satellite.
2. HD-Cable DVR, HD-Satellite DVR, or TIVO-HD.
3. Over-the-Air Antenna combined with an ATSC tuner in the HDTV.
4. Blu-ray Disc or HD-DVD Player (Blu-ray is preferable as HD-DVD is now discontinued). For more details on Blu-ray, check out my Blu-ray and Blu-ray Disc Player FAQs.
5. Upscaling DVD player or DVD recorder with HDMI output. This is not true High Definition, but an upscaling DVD player can provide a much better image on an HDTV than a standard non-upscaling DVD player, unless the scaler in the HDTV is very good on its own.
6. High Definition Camcorders - such as HDV or AVCHD format camcorders, and also the new breed of compact hard drive and memory card camcorders that also have HDMI output connections.
Sources that do not provide a High Definition signal:
1. Analog Cable or Basic Digital Cable.
2. Standard Satellite service.
3. DVD recorders, DVD Recorder/Hard Drive combinations, and DVD Recorder/VCR combinations that do not feature HDMI outputs and DVD upscaling.
4. VHS VCRs.
5. Standard Resolution Analog and Digital Camcorders.
High Definition and Content Streamed from the Internet
An increasing popular source of content for TV viewing are TV programs, movies, and videos that is streamed from the internet. As a result, an increasing number of TVs, Blu-ray Disc players, and set-top boxes now incorporate the capability of accessing internet-based media content. This presents a mixed-bag with regards to high definition resolution. The problem is that the quality of what you see on the screen varies from service to service, and also depends on how fast your internet connection is.
For example, services such as Vudu can provide a 1080p high definition signal to your HDTV, but if your internet connection speed is too slow, you will get signal stalls and interruptions, or may just stop. As a result, you may have to select a lower resolution option for accessing the content.
One solution that Netflix provides is that is automatically detects your internet speed and matches the image quality with your internet speed, which makes viewing convenient, but you may not be seeing a high definition result.
For more details on what you need know about the relation of internet speed and viewing quality, read our report: Internet Speed Requirements For TV and Movie Streaming.
Confirmation Your HDTV is Receiving a High Definition Signal
The best way to verify whether your HDTV is indeed receiving a high definition video signal, is to see if you can locate the INFO button your TV's remote, or see if there is an onscreen menu function that accesses the input signal information or status.
When you access either of these functions, a message should display on your TV screen (usually in the upper right hand corner, but may be displayed differently depending on TV brand). This message tells you what the resolution of your incoming signal is, either in pixel count terms (740x480i/p, 1280x720p, 1920x1080i/p), or just as 480i/p, 720p, or 1080i/p.

4K Ultra HD
If you own a 4K Ultra HD TV, just as with an HDTV, don't make the assumption that what you are seeing on the screen at any given time is true 4K. There are some important, additional, factors to take into consideration with regards to what you are really seeing on the screen.
