How to get 8k on display and bitstream surround sound at the same time?

With the rise of 8K displays, 8K content, and HDMI 2.1 sources, it’s time to talk about 8K audio video distribution. Consumers are buying 8K TVs and gaming consoles, but their other devices are 4K, or 1080p. Going directly from the 8K gaming console to the 8K TV works great,but what if you want surround sound too? If you want bitstream surround sound audio from HDMI 2.1 sources like a PS5 or XBOX Series X, you could try to go directly from the source into an AVR.But most AVRs can’t handle 8K or HDMI 2.1, and the signal won’t get through to the TV. How do we get 8K on the display and bitstream surround sound at the same time? With our 8k Matrix switcher 4×2, you can watch 8K content and listen to full surround sound audio without sacrificing video quality. It is an 8K matrix switcher with 4 HDMI inputs and 2 HDMI outputs. It supports HDMI 2.1 features like high frame rate, variable refresh rate, uncompressed audio, and 8K video resolutions up to 40Gbps (FRL5), making it ideal for 8K audio video distribution. But how do we get the surround sound to work? AVRs will still cut the video quality down if they can’t handle the massive 8K 30hz or 4K 120hz content. We can get around the AVR with the 8K Matrix Switcher 4×2. One of the HDMI outputs has a built-in video downscaler that can take 8K and scale it down to 1080p without messing

How does Bitcoin work?

It is not easy to read and can make bookkeeping a little annoying, but it allows Bitcoin transactions to be tracked across the network, which is important given the Bitcoin mantra of transparency and immutability. By using this system, people can trace every Bitcoin transaction back to the origin of the currency, with the understanding that anyone can send a Bitcoin to anyone at any time. By routing transactions through banks and other financial service providers, each transaction is validated by each node in the Bitcoin network and recorded on a secure blockchain.     Once approved, the transaction will be merged with other transactions to form a block that will be added to the ever-growing transaction chain. The transaction data is then sent via a decentralized network of Bitcoin nodes.   Once completed the block is encrypted and the transaction log is permanent; it cannot be removed from the blockchain or altered. The blockchain is public, which means that anyone who owns the blockchain can view the transaction logs.   Public blockchains allow users (who need computing power) to participate in the authorization and recording of transactions on the blockchain via nodes. Each node has its own copy of the Bitcoin blockchain, and when the network approves or dismantles a block, it is updated, trusted, and verified. Network nodes validate transactions and add them to their copies of the blockchain, which are then broadcast and added to other nodes.     Bitcoin transactions make the existing public register accessible to everyone, making transactions harder to

Avoid Bitcoin Scams

Avoid scams to help protect yourself and your finances Blackmail In most cases, this method works by sending an email with a message claiming that their computer has been hacked and that they are being blackmailed by using Bitcoin as a means of extortion. The scammers can either suppress the material or spread it across their various social media platforms. This is a phishing scheme that uses stolen email lists to infect thousands of people. Fake Exchanges Bitcoin has become more popular, and many people are taking advantage of this by setting up fake exchanges. These are typically designed to trick users into thinking they’re getting something for a steal. Be sure to use a reputable exchange when buying or selling bitcoin. Free Giveaways/Prize Giveaways Due to the nature of the internet, scammers can easily spread information about fraudulent websites and offer free digital currencies in exchange for personal information. This is why it’s important to report suspicious content. Impersonation Creating a fake social media account is very easy for con artists to do. Once they’re able to impersonate an author or a person, they often wait in wait for their intended target to publish content. After following up with a follow-up message, the impersonator would then try to trick others into thinking they’re responding to their message. impersonators can also try to trick others into clicking on links or sending personal messages in order to commit fraud. Never participate in free giveaways. If you receive an odd request from

Is buying an Antminer a good idea?

If someone considering buying an Antminer, like S19Pro 100TH/s, or Innosilicon A10Pro 720M in order to mine bitcoins. These ASIC sold for USD13000 (S19Pro) for a brand new devices, and USD 16000 (A10Pro)for used devices, which is a big investment for them. And they also will consider the cost of electricity in their city. Is it realistic for us to pay back our investment in less than a year, or is it more likely that the product will become obsolete too quickly? New miners and Experienced miners, probably all have same questions in mind. We can search the data, trying to calculate for worst-case scenarios, best-case scenarios & the middle ground results. What happens if network difficulty increases to levels seen before the China ban & total network hash rate sees the previous top as well? Are we still profitable? What happens if Bitcoin stays stagnant and trades sideways for the next year or even goes on a downward slope – are we still profitable? How much money am I investing into getting the proper electrical setup & on and on? Now China is in “Great Bitcoin Migration” hundreds of properly wrapped bitcoin miners were loaded onto the plane again. these miners no longer have a place in China but are the most coveted production tool for cryptocurrency gold miners in the US today. As you may know, the shipping cost is a great expensive way for hundreds of miners nowadays and it’s not easy for Chinese to build new

Top Tips when connecting Fiber optic HDMI cable

When you use a long fiber optic hdmi cable over 10meters and beyond, there are important tips you need to know before connecting with your devices or install in your wall. Cable is unidirectional. Follow the connector printing to ensure proper operation of the cable. The connection will not start when you connect them in the wrong way.  Wiring and Connections IMPORTANT! Installation Requirements •Follow the connector printing to ensure proper operation. •Due to the core of the HAOC being fiber optic, the cable has a bend radius greater than 45mm. Keep this in mind when routing cables around objects and inside of walls. •The cables have a max pull tension of 15kg/33lbs. Keep this in mind when routing the cable within cabinets or walls to avoid damaging the cable. 3 easy steps to master the decoration of buried wire tips: Before wiring, please connect the use of equipment for testing to ensure normal signal transmission before wiring. Both ends of the plug with anti-dust cover, do not pull hard, twist, or knotted through the tube, so as not to damage the internal core and resulting in signal attenuation distortion. 2. please pay attention to distinguish the directionality! After being pre-buried into the wall, the HDMI connector must be protected to avoid accidental injury during renovation. It is recommended the pipe width is more than 30mm, thus easy wire through the tube, or subsequent wire replacement easier to disassemble. 3. Please do not bend the wire less than 90 °when
