In the quest to improve the picture quality, LED TV manufacturers have introduced several new technologies to help achieve the sharpness and black levels we’re used to seeing with plasma-based flat-screen TVs. One such improvement comes in the way that LED TVs are illuminated. In this post we discuss the various benefits of the four different backlight methods incorporated in LED TVs. We also explain the differences between “full-array” and “edge-lit” backlighting and also discuss how local dimming can make a difference in picture quality. Continue reading

When it comes to digital cables, HDMI cables are the most advanced cables you can get today. HDMI cables transmit both uncompressed audio and digital video signals from one device (such as a Blu-ray player) to your flat-panel TV. This ability to carry both audio and digital video signals is great because it eliminates the need for separate audio and video cables, thus reducing clutter. What’s more, you get the highest quality signal possible because HDMI cables support all high definition TV (HDTV) resolutions (including 720p, 1080i and 1080p) as well as EDTV (480p) and standard definition signals. As for audio, while even more improvements are in the works, HDMI cables currently support up to 8 channels of 24-bit audio. This is the best you can get today. Continue reading

In 2009, people across the US were scrambling to keep pace with the digital TV transition. This digital switchover, which is just part of a larger move toward digital conversion going on across the globe, required every full-power TV station in the country to broadcast only in the digital format. For many people, the transition to digital ATSC signals had little impact on their TV viewing experience because cable and satellite set top boxes made it possible to view the new signal format on older analog televisions. But in the long term, cable boxes and satellite boxes (not to mention digital-to-analog converter boxes and analog sets running through gaming consoles, VCRs, and DVD players) are an inelegant solution and inferior to the new digital TVs that can make use of the full spectrum of benefits of the ATSC signals.

Shopping for and comparing HDTVs is fun, but it can also be confusing. Take, for example, TV contrast ratios. It’s an important specification to understand but it’s also one of the more misleading features on televisions today. That’s because even though TV contrast ratios can help you make a smart decision when it comes to buying an HDTV, it’s also a spec that doesn’t have an industry-wide standard of measurement.
