Audiophile audio and video cable how to choose? White people need to pay attention to these misconceptions

A
About the audiophile line, the audio system used in the main audio line, digital line, speaker line and power cord. A wide variety of these wires on the market, advertising is dazzling, many wires are mythical, so that people have too many expectations and fantasies about the audiophile line, in fact, there are a few big misconceptions here. Myth No. 1: a superstitious belief in the power of senior wire, regardless of the condition of their own equipment, thought that as long as the change of a good line sound effects will suddenly improve. In fact, if the equipment can not reach a certain quality, it is equivalent to an insurmountable bottleneck, that is, the use of fever wire, will not fundamentally improve the performance of the equipment, spend these costs to buy senior wire, rather than simply upgrade the equipment itself, even from the room acoustic processing or speaker placement up to work on the harvest will be much greater than the replacement of expensive senior wire. Myth 2: Advanced wire, only the icing on the cake, no power to save the day. For signal lines and speaker lines, many people to line tuning sound. Although different wires have a certain impact on the sound of the equipment, in fact, the use of wire is the sound of this quality, because the wire itself is a passive signal channel, just a signal transmitter, it does not have the ability to amplify the signal. For example, a device low frequency is not good, go to find more low-frequency wire, it sounds like the low frequency is enhanced, but this is through the wire on the high-frequency signal attenuation in exchange for the bad will make the entire frequency response of the device becomes uneven, so it is not worth the loss. Therefore, you should choose a neutral, low sound coloring wire, this type of wire will not affect the performance of other equipment, easy to match with other equipment, so as to truly play the potential of the equipment. Myth 3: underestimate the impact of the power cord on the equipment. Power cord on the impact of the equipment many people do not think, in fact, although the length of the power cord for the entire grid system is very short, but generally connected to the wall of the grid wiring cross-section are larger, and ordinary random power cord cross-section are very small, the middle of the wire any part of the diameter of the small will become the weakest link in the entire circuit, thus becoming a constraint on the power supply. Moreover, the professional power cord also comes with multiple layers of shielding, which can reduce the impact of interference in the power supply to a certain extent. Myth 4: Silver wire is better than copper wire. Although the silver wire has a low impedance to high frequencies, the transmission of high frequencies is better than copper, but sometimes excessive, while the low frequency performance is poor. Pure silver wire is not only expensive, and easy to oxidize, so it is relatively rare, most are other metals of silver alloy. The copper wire is more uniform transmission of high and low frequencies, but pure copper impurities, crystallization, more, not suitable for making audio wire. Now most of them are used OFC oxygen-free copper, due to magazine reduction, the sound tends to be clear and transparent. With the improvement of smelting and annealing technology, there are now large crystalline oxygen-free body and single crystal copper, making the sound transmission more balanced. This shows that you must be careful to play with the wire, not blindly. Wire is different from other equipment, it is not graded, more with the so-called best wire. Figure out the characteristics of the wire, the wire and equipment to make the best match, affordable wire can also come out satisfactory sound. Finally, once again to remind audiophiles, should be based on their own system to buy audio cables, if you need advice, please contact the official customer service. Khyber 15 years focus on the field of audiophile audio and video, its wire because of good quality and after-sales service to win the trust of millions of audiophiles, double 12 there are heavy benefits, copper wire to buy old fiber HDMI cable, audio cable discount, send video and the opportunity to win free benefits.

Quick look! HDMI cable connection common problems and solutions!

A
No response after connection? ❶ Please check whether the TV signal input channel is adjusted to "HDMI input", and switch the input setting of the TV first. Path: Menu - Input - Signal source - Interface, select according to the HDMI cable and the TV socket (there may be 1-5 of them depending on the brand). ❷ Generally, the default computer monitor output alone, switch the video to adjust the computer resolution to the TV's initial required resolution and refresh rate, path: desktop right-click the mouse - Properties - Settings - Extended mode. Generally set the computer's resolution to 1024*768, refresh rate of 60HZ, and then adjust the TV resolution after connecting. ❸ If it is a laptop computer, you need to switch the output screen, the shortcut keys are different for different models, and the keyboard combination is used to open and switch the second monitor output before the second monitor signal is output to the TV. Some computers need to be shut down and connected or restarted after being connected. TV color bias or snowflakes? This situation may be caused by poor contact between the TV and the computer's HDMI connector, or the interface may be exposed to moisture for a long time, or the plug is frequently plugged in and out causing loose contact, it is recommended to change other interfaces for testing. What are Copy Mode and Expansion Mode? ❶ The computer and TV display the same content in "Copy Mode". ❷ "Extended mode", the TV as an extended monitor will not display the status bar, shortcut buttons, only a desktop wallpaper, at this time, the computer can also carry out other operations, the screen on the TV and the monitor screen completely independent, do not interfere with each other. Only image and no sound on TV? ❶ HDMI connection cable is capable of transmitting both video and audio. There is an audio signal converter in the HDMI transmission chip of the computer, and the driver of the device should be installed correctly to transmit audio signals normally through the HDMI interface and HDMI cable. So we first need to make sure that the driver is correct. ❷ Select HDMI graphics card built-in sound card as the default in the computer Control Panel - Sound and Audio Settings - Sound Playback. For example, the device that shows Realtek Digital Output is the audio output of HDMI, so right-click and select Set as default device. Can't the TV display full screen with bezel? If you need a full screen, you can first adjust the computer's display output resolution to match the TV's display resolution, then right-click on the computer desktop and select [Screen Resolution] - [Adjustable Resolution] - [Advanced] - [Monitor]. ❷ Select the appropriate refresh rate in "Screen Refresh Frequency". Select the "image reset" function inside the TV's menu options, and if that doesn't work, adjust the graphics card's scaling function inside the control panel of the graphics card. HDMI cable pre-buried direction is reversed? Fiber optic HDMI cable is divided into directions. If it is not pre-buried, you can directly pull it out and adjust the direction. But if it is buried, the only way is to pull out and re-buried.
