Is Buying a 1080p TV Wrong Today?
HDTV: Set the television correctly
Sharp images, rich colors, strong contrasts - everything looks flawless on the LCD or plasma television during a demonstration in a shop. In the living room at home, on the other hand, the picture of many flat screen TVs seems rather dull. The manufacturer's factory settings are often to blame: They do not match the individual lighting conditions in every living room. With the help of a free full HD test image, the TV picture can be sensibly "tuned" and the television set correctly.
Testers from Stiftung Warentest repeatedly complain that only a few televisions deliver a good picture with the factory settings. With around two out of three devices, the picture can usually be improved with a few settings. In order to get a neutral, natural picture on your flat screen television, which shows both dark and light areas in the picture, the only thing that helps is adjusting the picture parameters.
Test image helps
It's easy with a test image. The Burosch company offers a suitable image for free download. All you then need for your perfect TV picture is a USB stick on which you can save the test pattern and, of course, a USB port on your TV. We will show you how to get the perfect picture step by step.
Assume the correct sitting position
Of course, the perfect TV picture depends on the sitting position you occupy in front of your television. Because: If you sit too close to the LCD or plasma television, you will clearly see some blurring and rough edges despite the image optimization. And that spoils television enjoyment tremendously.
To find out the minimum distance for your HDTV television, use the information in the table. During the adjustment, make sure that you keep a sufficient seat distance.
|Full HD (1080p)||HD (720p)|
|94 cm (37 inch) HDTV||1.3 m||2.0 m|
|102 cm (40 inch) HDTV||1.4 m||2.1 m|
|107 cm (42 inch) HDTV||1.5 m||2.2 m|
|117 cm (46 inch) HDTV||1.7 m||2.5 m|
|140 cm (55 inch) HDTV||2.0 m||2.9 m|
|165 cm (65 inch) HDTV||2.9 m||3.4 m|
|80-inch HDTV||3.0 m||4.2 m|
Keep a sufficient distance
An example: You are sitting in front of a flat screen TV with a screen diagonal of 102 cm (40 inches) and are looking at the Full HD-optimized test image, then the minimum distance should not be less than 1.40 meters. Otherwise you may not see the picture for all the pixels.
Later, while watching TV, the incoming signal decides how close you can move your armchair in front of the screen. For example, if you use DVB-S via satellite with a 37-inch monitor, a sitting distance of around 2 meters will probably provide you with the best picture.
Use the best sources
With digital TV, the quality of the receivable signal is more important than ever. For example, the PAL signal in digital terrestrial television DVB-T is so heavily compressed that unsightly blocks and artifacts appear. Digital transmitters via cable (DVB-C) or satellite (DVB-S) are better. Of course, HD signals and Full HD films from Blu-ray Disc are best. This is where the investment in a large-format flat-screen TV pays off.
