The WOWVision! HDTV Picture Quality Help Guide If Your HDTV doesn't make you say "WOW"!!! The WOWVision! HDTV Picture Quality Help Guide is unlike the cut-and-paste HDTV websites that populate the internet. WOWVision! is the the result of observations obtained from thousands of DTV and HDTV service calls. This is the one place that you will find the answers to poor picture quality and poor performance of HDTV and DTV systems. What is most apparent in the field is that there is a great lack of knowledge and a large amount of confusion. regarding high definition sources, connections, picture quality, digital systems, the Digital Transition, and the digital conversion box. The WOWVision! site addresses each factor of poor picture quality from viewing distance, cables, connections, settings, and calibration, to signal quality, antenna and dish alignment. The WOWVision! website contains information and tutorials on picture quality, aspect ratio, calibration, satellite dish alignment, signal meters, digital signal processing, and terrestrial or OTA HDTV antenna alignment. From the basics of the HDTV Do's & Don'ts to the details of signal science, including signal quality, signal-to-noise ratio, BER (Bit error rate), pixelation, mosquito noise, artifacts, grounding, and ground loops. Resources including local HD digital broadcasts and broadcasters, technical and non-technical information regarding digital systems and their operation, and installation tips and tricks. The FAQ contains answers to some of the most commonly asked questions. The WOWVision! Interactive High Definition Glossary is the most complete glossary of DTV and HDTV definitions available on the internet. It contains hundreds of definitions and links regarding all aspects of HDTV. Links are included on the pages where they are contextually related. Everything contained within this site has been obtained and verified by research and proven repeatable RESULTS. This knowledge was acquired from correcting Dish Network and DirecTV satellite systems, and from installations of Off-air antennas, digital conversion boxes, and HDTV calibrations.
My quest for answers began in 2005 as I began installing Dish Network systems. In 2006 alone (THE year of high definition for the satellite industry!) I dealt with over 1000 problem systems and upgrades. Many times I've been the 3rd, 4th, and even 5th technician sent out before the problem was resolved. The information contained here has resulted from troubleshooting and upgrading 1000's of DTV and HDTV systems. In attempt to answer the 720 vs. 1080 picture quality question, it became clear that picture quality of digital systems does vary. The problem was that it wasn't related to the "720 vs. 1080" consideration. Since then, I have been observing and researching picture quality and low signal artifacting in digital systems. HDTV is all about details. You must pay attention to the details when installing and setting up an HDTV system. Detail comes from very subtle, or small differences. For example, here is what color calibration is all about - better detail. This detail comes from subtle differences in texture and shade. To get the general color is not hard, but for the quality to be "WOW!", the color must be correctly adjusted. If the color is out of calibration (which all TV's are as they come out of the box...), it is impossible to produce the smallest variations that give the best texture and detail. The further from the correct color calibration that you are, the less detail and "WOW!" you will witness. The more accurate your calibration is, the better your detail will be. Properly calibrated televisions show less motion blur and reduced or eliminated mosquito noise. Properly calibrated televisions also give a much better quality of SDTV. Digital televisions are very capable of producing a great picture in both HD and SD. The down side is that they also very accurately show how far from "WOW!" you are when the details have not been addressed. Calibration is only one of the many details that will increase your picture quality.
