Beginners must watch: How does TV buy a book to spend money beautifully?

If the last time you bought TV was 10 years or 8 years ago, your thinking may still be on the antiques like CRT and plasma. Wake up, now all 2016!

Recently, the color TV industry has gotten quite a stir. We want to take the opportunity to change our parents' TV to a new TV. We can usually not pay attention to household appliances. Is there any professional purchasing dictionary? How to spend money with texture? There is money in the pocket. It is the ability to spend money beautifully. First of all, make it clear that investing in screen size is the wisest choice. First decide whether the TV is in the living room or the bedroom. Whether to hang the wall or not, and then measure the corresponding viewing distance, you can follow the map:
American Consumer Association Recommended Size

电视 The TV always looks smaller, absolute

❷ The difference between the new TV is at least 10"

❸ Now 49" to 65" 4K panels are more cost effective

曲面 Surfaces only buy big, the bigger the immersed the better

❺ There are marked distance stickers in the store, feel it in the field

Next, we must pick the quality. In fact, those complicated terms are paper tigers. Moreover, many manufacturers also like to play word games in contrast, color gamut, and refresh rate. Better believe in your own eyes and practice what you know. Internet to find a 4K source, there are 2 U disk, to the store to ask promoters to do a comparative demonstration.
Of course, different groups of people will have different focus on picture quality: It is better to enjoy HDR when watching movies. Can be transferred to the movie mode, observe the picture of cold and warm colors, skin color is true reduction, in particular, whether the dark details are clear and rich;

Documentaries must have 4K and wide color gamut technologies. The picture quality should be delicate and the colors should be bright;

Watch the game focus on dynamic effects. The scene where the player runs can't have any trailing or stuttering. The gamers who like DeSur should pay attention to the data of input delay, and can be measured, or check the Internet.
According to the importance of comprehensive considerations: Contrast (especially the dark details) Wide color gamut Color reproduction Resolution, refresh rate, input delay.

OK, the specified action is completed, the following is the optional action...

Now the trend of color TV design is curved surface, ultra-thin, and narrow borders. The appearance party should move closer to this aspect.

In addition, we must pay attention to do not look at some products grow ugly, but they think of beauty in the heart ah, use renderings want to fool everyone. See how the seams of the curved border work? Will the TV shake back and forth when it is mounted on the pedestal? The remote control can reflect the workmanship in particular and can find a promoter to come and play.
Regarding intelligence, many people are particularly concerned about the amount of content, in fact, most of the built-in applications are very limited, it is better to buy the appropriate TV box according to content needs. Regarding the system, the boot speed, operation fluency, and the stability of the mobile screen are all very important. It is recommended to find a physical store with a network to experience it. After this step, consider the issue of money. In addition to buying on the Internet, you can check if there are any preferential activities such as energy-saving subsidies and old-fashioned replacement for offline stores, which may be cheaper after bargaining. Don't forget to negotiate with the promoters about the cost of wall-mounting and door-to-door installation.

Cough and cough focus on the final

Everyone took notes
❶ It's absolutely wrong to spend money on large sizes! At least 10" or more

ç”» The quality effect must go to the scene to test

智能 The intelligence and design are reflected in the details

预算 The budget includes not only televisions but also accessories such as TV boxes, wall mounts, HDMI cables and patch panels

There are good hardware and display effects, of course, with a rich content resources, the combination of software and hardware can play the greatest value of a TV. In terms of content, it is recommended to install a sofa butler - the sofa butler is a third-party app store designed specifically for smart TVs, Android box users, carefully providing television, box users with high-quality television exclusive version of the application, including with live Or on-demand video and audio and video software, various types of recreational competitive video game software and daily office entertainment management system management tools. click to download

4G Industrial Router

Analysis of advantages and disadvantages of 4G industrial routers
First, what is the classification of industrial routers?
Industrial Router (a communication device that can be divided into 2G routers, 2.5G routers, 3G routers and 4G routers according to network standards.

For users, you can communicate with the Internet by setting a default gateway on your PC or network device. In fact, the default gateway configured for network devices is the packet export for network devices. After the packet is sent to the Ethernet port of the router, the router performs the next job, so the router is an Internet relay.

Second, how do industrial routers work
So how does the router forward the packet? Just like getting somewhere, you need to place a route. This route is a routing table. This routing table contains all the destination network addresses owned by the router, as well as the best path to reach those networks through the router. This is because there is a routing table, so the router can forward packets according to the routing table. That's how routers work.

Understand what is an industrial router and how it works, it is not difficult to understand the advantages and disadvantages of the router. Here we focus on the advantages and disadvantages of 4G industrial routers.

Third, the advantages of 4G industrial routers
For networks interconnected via single-protocol industrial-grade wireless routers, the same or different protocols can be used at layers 1-2. Layer 3 uses the same routable protocol and requires the same or compatible protocols at layer 4 and beyond.
Industrial routers can perform complex routing calculations and are suitable for connecting three or more large networks with complex network topologies.
Industrial-grade routers can isolate broadcast storm information in the source network, thereby reducing and mitigating the impact of broadcast storms.
Multiprotocol industrial wireless routers can be used as network interconnection platforms using different communication protocols because they can connect to the network using different communication protocols.
The entire network router can also be used as a bridge to handle non-routable protocols.
Industrial 4G routers enable you to isolate unnecessary communications so that the interconnected network maintains its own area of independent management and control, thereby improving network security performance. Therefore, industrial-grade 4G routers are commonly used as firewalls to restrict access to the internal and external networks (Internet) of the LAN, as well as the internal areas of the LAN, and act as network masking.
It can provide reliable transport and prioritization services, and industrial LTE routers do not need to maintain a persistent connection between networks that communicate with each other.
Complete Netcom router network segmentation improves network performance and reduces host load.
Third, the advantages of 4G industrial routers
High price
When installing an industrial LTE router, it is difficult to install and maintain due to the large number of initial configurations
If you spend more time processing, the transmission performance of the entire network of the industrial router will decrease.
Unlike Bridges, routers across industrial networks are protocol-related. Each advanced protocol used for network connectivity must be configured separately, and an industrial-grade network-grade router with a separate protocol for each protocol must be provided.
Industrial Netcom routers do not support non-routed protocols, so when interconnecting multiple networks, there are restrictions on the protocols used by the connected networks.
