    How to Choose a DP Cable (part 2)

    3.The third vital factor is about the different version of DP cables. Currently, there are two types of DP cable which dominated the market. They are known as DP 1.2 and DP 1.4. Comparatively, DP 1.4 is the newest version of DP cable which enjoys the merits of wider bandwidth(32.4 Gbps) and larger compatibility of resolution(up to 4K@144Hz and 8K@60Hz). On the other hand, the old version of DP 1.2 is only 2K 144Hz, 2K@165Hz and 4K@60Hz supported. Nevertheless, there also lies a significant price gap between DP 1.2 and DP 1.4. If you only intend to purchase hardware that is under the standard of 4K@60Hz or you are satisfied with your hardware and haven’t got a plan to update your hardware in near future, DP 1.2 is far beyond your need. After all, most ordinary hardware user never requires 8K@60Hz or 4K@120Hz visual experiences. These visual levels also exceed most current graphic processor’s ability. However, if one of the readers is a heavy E-sports players who feel desperate to pursuit not only ultimate refresh rate but also ultra-resolution. A superb graphic processor should be accompanied with a cable with extra bandwidth such as DP 1.4 or HDMI 2.1. 4.The last part of this passage would like to foresee DP 2.0. On June 26, 2019, VESA had officially released the 2.0 version of DP interface. Overall, it theoretically reaches the payload of 77.37Gbps which is almost triple than the last version. Apart from that, DP 2.0 is also designed to …

    How to Choose a DP Cable(part 1)

    In our daily game and film usage, with the high-speed development of GPU hardware and filming technology, The PS5 and Xbox Series X, which has been released in 2020, can currently output 4K/120Hz graphics, while Nvidia’s recently RTX 3090 graphics card can output 8K graphics. This trend has put old series of the cable into an unfavourable situation. For instance, A display with 2K resolution and refresh rate of 165Hz can only display images with 2K resolution and 75Hz refresh rate under sRGB colour space when connected with HDMI1.4 interface. Only DP1.4 and HDMI 2.1 have the ability to fulfil such level of image output. Hence, here we provide some tips for choosing DP cable to cater to one’s game or film need. 1.To begin with, There are two types of DP connector. The standard DP connector is about the size of a USB connector, and this type is typically used for PC displays which support DP interface. The smaller mini DP connector is mainly designed for laptops which also includes Apple products. This could include Thunderbolt, which is widely used in Apple products. You can connect any DP display to a Thunderbolt source using a standard DP cable. As a result, the first and foremost thing is to check the DP interface type of your devices. There is no possibility of connecting your computer with your display while you fail to choose the correct type of DP interfaces. 2.Secondly, except for the interface type, length and material of the …

    What is the longest transmission distance of the VGA cable

    The history of the VGA interface can be traced back to 1987. The blue plug is generally used, and it is also the most recognizable interface. The VGA interface has 3 rows of pins, 5 in each row, totaling 15 pins. Our childhood memories—Big head monitors use VGA ports. The VGA interface transmits analog signals with weak anti-interference ability and supports a maximum resolution of 1080P. The transmission distance of the 3+4/6 VGA cable is 15-30m. The oxygen-free copper VGA cable with thick conductor and good shielding can reach a transmission distance of 30m, and the inferior VGA cable over 15m will cause image quality problems such as smear and blur.

  • How to Choose a Network Cable

    The network cable actually has a great influence on the network speed. No matter how good your switch or router is and how high the broadband speed is, if the quality of the network cable is not good enough, the entire network will be greatly reduced. At present, the most commonly used network cables in the market are Cat.5e and Cat.6 network cables. Cat.5 network cable has a maximum transmission rate of 100Mbps, which only supports 100M networks, and is now used less. Cat.5e network cable is a transition product from Cat.5 to Cat.6, with stronger anti-interference performance, lower attenuation and higher cost performance during transmission. Cat.5e network cable can be used in Gigabit Ethernet, can stably support 100Mbps transmission rate, and can negotiate up to Gigabit (1000Mbps) rate. Cat.6 network cable can stably support Gigabit networks, and its transmission rate is much higher than Cat.5 and Cat.5e network cables, up to 1Gbps, and can stably support 1000Mbps transmission, and can be used in a network environment requiring a transmission rate higher than 1Gbps. The copper diameter of the Cat.6 network cable is thicker, and the cross-insulating skeleton is added, and the near-end crosstalk and return loss of the network cable are lower. How to choose a network cable?  ①Copper conductor of network cable The conductor diameter of the Cat.5e network cable is 0.511mm, and the conductor diameter of the Cat.6 network cable is 0.574mm. The thicker the copper conductor of the network cable, the smaller the resistance, the better …

    How to Choose an HDMI Cable(Part I)

    HDMI interface version To choose an HDMI cable, first look at the version number of the HDMI interface. The HDMI interface version is different, the bandwidth and supported technology are also different, the high version can be compatible with the low version, so it is best to match the HDMI interface when selecting the HDMI cable, at least not lower than the interface version. If it is lower than the interface version, high-definition images cannot be transmitted. On the contrary, if it is higher than the interface version, although it can be used, you will spend more money. HDMI cable connector The connectors of the HDMI cable are generally gold-plated and non-gold-plated. The gold-plated connectors will have better corrosion resistance, conductivity and high temperature resistance. So normally, cables with gold-plated connectors will be better. Many gold-plated connectors on the market use 24K gold-plated. The brightness is relatively high and it is easy to distinguish. But it’s not that it’s bad if it’s not gold-plated, because the PIN inside the HDMI connector will ultimately work during use. This is the main connection point. This PIN is mainly made of tin bronze. At the time of production, the PIN is first plated with nickel and then gold. Therefore, if the HDMI cable with good workmanship, carefully look at the PIN, you will find that there are three layers. Thickness of HDMI cable Some HDMI cables are thick and some are thin, how to choose? Normally, for the same brand, the thicker the …
