Standard HDMI Cable
The Standard HDMI cable is designed to handle most home applications, and is tested to reliably transmit 1080i or 720p video – the HD resolutions that are commonly associated with cable and satellite television, digital broadcast HD, and upscaling DVD players.
Standard HDMI Cable with Ethernet
This cable type offers the same baseline performance as the Standard HDMI Cable (720p or 1080i video resolution), plus an additional, dedicated data channel, known as the HDMI Ethernet Channel, for device networking. HDMI Ethernet Channel functionality is only available if both linked devices are HDMI Ethernet Channel-enabled. Continue reading Finding the Right HDMI Cable→
What is Dolby Vision?
Dolby Vision is the brand name for a high dynamic range (HDR) 4K video format developed and promoted by the folks that brought us Dolby Surround and all its subsequent permutations. To use the Dolby Vision logo on a TV or Blu-ray player, manufacturers must pay to certify their products and license the name. The Dolby HDR format is also used in video production, making it a professional as well as a consumer brand.
As a refresher, HDR was introduced as a way for TVs to display a greater number of colors (by increasing the color gamut) and more-intense colors (by boosting specific brightness levels). Before HDR, sets were limited by an old video specification for HDTV known as Rec. 709, which was based on technical limitations going back to the ’90s.
Today’s LCD and OLED sets have the capacity to display many more colors than older sets, but they didn’t have a way to reach their full potential until HDR came along. Continue reading What Is Dolby Vision?→
A “nit” is another way to describe a brightness of 1 candela per square meter (cd/m2). A movie theater screen, in your average movie theater, can probably get as bright as about 50 nits. If your TV is a few years old, pre-HDR, it can probably reach between 100 and 400 nits. Plasmas (now defunct) would be on the low side of that, while high-end LCDs on the other side.

The 6 series this TV with full-array local dimming, Dolby Vision HDR and Roku’s sweet Smart TV system.
Local dimming, which illuminates different areas (zones) of the screen independently, is one of the best ways to improve LCD image quality. TCL has upped the number of local dimming zones to 96 on the 55-inch version of the 6-series and a whopping 120 zones on the 65-incher. Compare that to Vizio’s M series, which only had 32 zones. More local dimming zones usually mean better image quality because they allow more precise control of screen lighting. Continue reading TCL 6 series Roku TV→
We’ve said it before but it bears repeating: Samsung’s QLED TV technology is not the same as LG’s OLED TV technology.
Sure they have similar names, down to the little slash that makes an “O” into a “Q,” but according to CNET’s tests for picture quality, OLED is superior. It’s also fundamentally different from the LCD-based TVs that comprise the vast majority of the market today. Samsung’s latest QLED TVs are still based on LCD, and while they have their strengths, they can’t compete with OLED. Continue reading How quantum dots could challenge OLED for best TV picture→

ARC, along with help from CEC, can simplify your home theater system in two important ways. The first, and perhaps most useful feature HDMI ARC brings to casual users is the ability to use one remote for all of your audio device’s most common functions. For this example, you may need to go into your TV’s settings and activate CEC (Consumer electronics Control), usually found in the general settings. Once everything is set up, your TV remote control could power on your A/V receiver or soundbar at the same time as your TV, and control the volume of either of those devices. Simplicity is the name of the game here. Continue reading HDMI ARC and eARC→
1.Supporting the Xbox One X is completely optional for developers
After having been direct competitors for so many years, it’s only natural that both Sony and Microsoft have started to look very similar. Microsoft introduced Achievements, so Sony brought out Trophies, Microsoft asked gamers to pay to play games online, and now so does Sony. The list goes on and on.
Sony has been very clear from the start that developers have to support the PS4 Pro if they want to release a game on the PS4. That doesn’t mean every game has to display in native 4K, but they’ll all have to be able to support the new hardware in some fashion. Continue reading What you need to know about the Xbox One X→
