带有以太网的标准HDMI线
这种线类型具有与标准HDMI线(720p或1080i视频分辨率)相同的基线性能,以及用于设备联网的额外专用数据信道(称为HDMI以太网信道)。HDMI以太网通道功能仅在两个链接的设备均支持HDMI以太网通道时才可用。 继续阅读 寻找合适的 HDMI线

什么是杜比视界?

什么是杜比视界?
杜比视界是由人们开发和推广的高动态范围(HDR)4K视频格式的品牌名称,它为我们带来了杜比环绕声及其他优势。 要在电视或蓝光播放器上使用杜比视界标志,制造商必须支付认证其产品和授权名称的费用。 杜比HDR格式也用于视频制作,使其成为专业品牌和消费品牌。
HDR被引入作为电视显示更多颜色(通过增加色域)和更强烈的颜色(通过提高特定亮度级别)的方式。 在HDR之前,设备受限于旧的HDTV视频规范Rec.709。今天的LCD和OLED设备可以显示比旧设备更多的颜色,但是在HDR出现之前他们没有办法充分发挥其潜力。 继续阅读 什么是杜比视界?

Nits galore

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. 继续阅读 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.

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. 继续阅读 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. 继续阅读 What you need to know about the Xbox One X
