You love gaming. So, you enthusiastically invest into a new monitor and a modern graphics card. And thereafter comes the BIG confusion – The choice of interface. You’re utterly confused as to which cable to use for connecting panel to the PC. Now, talking about display interfaces, there are four major ones that we know of as PC centric - DVI, HDMI, VGA, and DisplayPort. All these cables are available in different combinations for both monitors and video cards.
Sometimes, the above display cables come along with a new monitor. And therefore, you might want to plug in the cable and start gaming without thinking of the results. However, if you are a passionate PC gamer, you need to choose from either display port cables or HDMI. Let’s find out on what parameters you can decide it: Understanding DisplayPort And HDMI As we all know, HDMI stands for High Definition Multimedia Interface. Most of the HDMI ports come with at least one video card side and they’re used for connecting electronic devices to a TV. It can be any display device, be it an A/V receiver, a game console or an Amazon box. Several computer-oriented monitors also come with an HDMI input. However, you are more likely to find this port on home monitor as compared to a business-oriented display. A modern video card features more than one DisplayPort connections. Although you will rarely find Display Ports on TVs and more on computer monitors. DisplayPort & Gaming: A Perspective There is no doubt about the fact that DisplayPort 1.4 comes with a great display. Although its 32.4Gbps bandwidth is not quite different as compared to HDMI. It comes with a 3:1 compression ratio, which means its virtually lossless and has the potential to display high definition videos. Now, in the latest DisplayPort version (Version 1.4), compression enables DisplayPort to work on USB Type C connection which enables one to experience HD video with 8K and HDR. It may also offer superspeed USB over a common cable. One more important feature of DisplayPort is its potential to power more than one display panels. So, if you make use of USB C with screens that support the cables, you would be able to image data and power through the same cable. It is also important to remember that DisplayPort 1.4 aren’t quite old. So, if you make use of an old model that supports DisplayPort 1.3, you can check out all its features. Come To The Point, Now! “Yeah! I heard all the rantings about the usefulness of the two. But now I need a solution.” You might say. Well, the cable that you choose depends on what you currently have and what you intend to have. Sometimes, you might have already decided what you want. So, let’s say you have chosen a GeForce Graphics Card as well as a G-sync monitor. In this case, you will notice that you don’t have a choice when it comes to display technology. Only DisplayPort cables work with G-sync. Hence, for a G-sync display, you might have to stick to DisplayPort for gaming. And what does the gamer do if both graphics card and PC display have DisplayPort and HDMI on board? The present versions of HDMI support high and maximum resolution. However, to have that, you might need an extremely huge system (which is not available as yet at affordable price) for playing games with the highest bandwidth that HDMI supports. Also, these games should also support these frame rates. Which means, just because HDMI resolution his high, it doesn’t make it the right choice for PC gaming. DisplayPort, on the other hand might be the right choice if you want to undertake gaming on multiple monitors but have one DisplayPort connection available. It is possible to split the DisplayPort with the help of DisplayPort hub. However, this works only if the monitor supports a feature named – Multi Stream Transport. In short, it would be better to run multiple cables from single video card instead of daisy chaining. The Video Electronics Standards Association (VESA) recommends DisplayPort Cable as a replacement for VGA and DVI when it comes to PC oriented gaming. When a group of electronic companies came up with HDMI, they intended it to be for TV implementations. Concluding… If any of the above information makes you upset for having only an HDMI port, don’t be. As such, if your monitor is FreeSync or G Sync enabled, you won’t see much of a difference in aspects like latency, frame rate, refresh rate etc. – things that gamers often boast about. If you are a gamer based in the USA or North America and are looking for gaming cables online, SF Cable is the place to buy from. Check out our collections of HDMI and DisplayPort Cables now!

The world of USBs. Inevitably and essentially important to venture into if you want to use them. Sometimes, even though we use them, we do not have much knowledge about the type we should use and why. Whenever we go for buying USB Adapters and cables, all we check is the purpose it needs to solve. This is when some detailed insights into USB might come of help.
Today, we shall talk about USB C cables. These days, it is quite common to find them everywhere right from charging cables to external hard drives. Although all USB C look the same, all of them offer different functionalities and capabilities. Let’s get to know few things about them we were previously unaware of. Introduction To USB C When it comes to transmitting data and power, USB C is the industry standard connector. The USB Implementers Forum – the body that develops and certifies USB standards developed the USB C connector. Above 700 companies are a member of this forum including companies like HP, Apple, Microsoft, Dell and Samsung. So, Is USB C Like Micro USB? At the first look of it, USB C connector looks like a Micro USB connector. It is of oval shaped and a little thicker as compared to other USBs. The best part about this USB is that if you line it up properly, there is no need to flip or change the sides to plug it in. Also, as it has the same connector on both ends, there is no need to figure out which end would go where. This is quite dissimilar to other USB Cables that you have been using for over a past few decades. USB-C & USB 3.1 With USB C, the default protocol is USB 3.1, which is two times faster than USB 3.0 at 10 Gigabits per second. The only drawback is that you can avail USB 3.1 in the large and original shape. Apart from desktops, you are more likely to see USB 3.1 ports with USB C connectors. USB Implementers Forum have categorized the USB 3.1 Gen 1 standard as meeting the data signaling rates and interface as USB 3.0. Hence, when you make use of 3.1 version of USB (Gen 1), it will work at the same speed as USB 3.0. USB 3.1 Gen 2 refers to data signaling rates at 10Gbps. (which is double to USB 3.0 and matches with the speed of single channel Thunderbolt) Port Support With the help of USB C’s potential for sending power streams and video signals simultaneously, you will be able to connect with an HDMI device, MHL or a native displayport, by assuming that you might have the right USB cables and adapters. The USB C spectrum also helps with audio transmissions. However, it has not replaced the 3.5 mm headphone jack on computers like it has for high-end Android phones. Google Pixel 2XL, for example, makes use of the USB C interface when it comes to data transfer and charging instead of its formerly used Micro USB. This is they case even if it includes the traditional 3.5 mm headphone jack. But before you buy the USB C port, you must check the specs on the PC that you want to buy as not all USB C ports are the same. The ones you have come across support the power delivery and data transfer over USB C. Now, although USB C supports HDMI displays and DisplayPort connection with an adapter, not every PC comes with the ports connected with the system graphics hardware. Compatibility With Cables And Adapters As we read above, USB C is compatible with older USB 3.0 ports and also perfectly goes with the USB 3.1 ports. However, due to the new port style, you would need cables and adapters with plugs for connecting anything that doesn’t have the USB C connector. If you buy a new laptop, it might come with the connectors. But otherwise, you will have to buy them differently. If you browse for PCs, you will be able to find several of them that support old protocols. However, if you invest into normal USB C cables, they would work with all the devices that support USB C. This would really help you get over the past agonies when using a mini USB cable to charge your micro USB phone wouldn’t work. Should I Invest Into USB C? Well, you must consider doing it in case you’re buying a PC. If you buy a sleek laptop, it will undeniably come with a USB C port, which means you would obviously be using it according to the current standards. But in case you prefer desktops, you will be able to find the ports with the gaming ones. It would be difficult for you to find USBs old Type A connectors. The next generation of cross-platform connectors has replaced the old ones. And USB C is sure to rock for the years to come! This Blog is Source from https://www.sfcable.com/blog/insights-usb-c-type/ It’s been more than two decades that the cable authorities have standardized data and voice applications as 4 pair, ScTP or Sc/FTP, balanced UTP, Sc/FTP cables that support up to 40 Gigabits per second on 30 meters for CAT8. The major reason behind this requirement is the demand for high bandwidth that meet with the customer requirements.
The rising interest in Internet of Things and Smart Systems have also changed the scope of future cabling systems. For example, HVAC, lighting sensors and other smart systems require less amount of bandwidth as compared to data applications. A sensor, when polled by a controller or an external event, doesn’t transmit more than some bytes of data. Due to the high demand of bandwidth for Ethernet Cables, IEEE has started developing a new protocol for ethernet which will operate more than a single pair of STP/UTP cable. Now, although the intent was to enhance the bandwidth available through four cables in industrial installations, 100Base-T1 and 1000Base-T1 are quite popular too. Advent Of A New Option During the month of March, this year (2018), IEEE802.3cg Single Pair ethernet task force authorities gathered near Chicago with the goal of defining electrical requirements for 10Base-T1 – the potential name. According to the task force, the approval for the standard might happen in June 2019. One of the biggest changes in the installation requirements is the total number of connectors that are permissible in a link. Industries are a target market for 100Base-T1 and cables and one can penetrate cable pathways as well as sealed enclosures in the installation when it comes to accessing the protected equipment. For electronics that are small, cost effective and consume less power, 10Base-T1 offers several advantages as compared to existing single-pair ethernet options. It will be the preferred choice in future when it comes to cabling the sensors, low data consumption devices and sensors. Also, in future, as networks become omnipresent, the applications of new systems will also go beyond cabling. The vehicles, for example, will become smart through future applications. Considerations For Cables Cables that support 10Base-T1 applications are compact and small or rugged and large. When it comes to commercial installations, the cable designers have to deal with thousands of sensors and devices. And with numerous cables to manage, it is better to have smaller routes. You might find 24 AWG conductors covered with thin jackets that lessen the cross-sectional size of the cable. At the frequency of 200MHz there is no possibility of alien crosstalk and hence it is possible to bundle the cables without worrying about signal interference. Cat6A UTP has thin jackets that increase the space between cable conductors to lessen the effects of alien crosstalk at 500MHz. With industrial installations in which you can use 1000-meter links, the contemplations are different. The long links go through insertion loss which you can solve in two ways. One, the 1000m link topology of 10Base-T1 has to use a PHY (a kind of ethernet transceiver) which operates at 20Mhz as compared to 200MHz for 15m PHY. Attenuation is proportional to frequency and length. And hence, long cables increase the attenuation and if you limit the frequency to 20Mhz, it will lessen it. Cabling conductors for 1,000m link segments could have up to 18 AWG diameter, lessening the attenuation further. The ISO/IEC and ANSI/TIA standard groups have also started defining connectors and cables for 802.3cg/10Base-T1. Development Of Single Pair Cabling Standards The ISO/IEC and ANSI/TIA structured cabling standard groups have developed specifications for single pair cabling for industrial and commercial installations with a wide range of distances and data rates. TIA is working on a new single pair cabling standard which will be known as TIA 568.5. This standard will define single pair cabling to support 10 Mb per second to 100 meters, 100 Mb per second to 15 meters and 1 Gb per second to 15 and 40 meters. This cable also supports an alternative of PoE known as PoDL – pronounced as poodle which has the potential to give up to 50 watts of power over a single 24 AWG pair. The TIA will also make amendments for the TIA 1005 industrial cabling standard which define the cabling that supports 10 Mb/s to 1000 meters. For counteracting the signal loss on long cables, the conductor size goes up to 18 AWG for this application. ISO is also working on making some changes. ISO 11801-9906 Ed. 1 and 11801-6 Ed.1/Amd.1 standard will cover the commercial cabling specifications for 10/100/1,000 Mb/s single-pair cabling, and 11801-3 Ed.1/Amd.1 will take care of cabling for industrial applications. Is This An End For RJ45 Cables? As you read before, ISO and TIA are already in the process of selecting a new single pair connector which they can use to support these applications. This with the intent to have a connector which is 1 half to 1 third the frontal area size of RJ45 cable and supports 1 amp of current – shielded/unshielded and conductor sizes from 18 to 26 WG. The future of field-testing specifications of single pair cabling is quite bleak. All that we know at this point in time is that the types of tests that the authorities might conduct and what would be the established standards for it to pass or fail. Although the applications might allow the usage of UTP cable, wise integrators may go for STP for keeping the alien crosstalk at bay. This Article is Source from https://www.sfcable.com/blog/single-pair-ethernet-cable-future/ 'Convenience' - there's something about this word that we love. Lazy lads, couch potatoes, and the most active individuals also appreciate if they get what they want without having to move. And if inanimate objects offer this kind of services, even better! Extension Power Cords befall into this category. They're not glamorous or interesting at all. However, when it comes to connecting your devices with the power sources far away, they seem to be a real blessing!
Whether you want to light up your house for the upcoming festive season or connect your television to an outlet in the other room, extension cords always come to your rescue. Well, as useful as these power cords are, they also have some drawbacks. If they make your devices overwork or create a fire hazard, things can get quite dangerous. Also, as these cords are long, people of a busy household can stumble and fall creating further injuries. You must be aware of how to use these cords. But, you must also know where you SHOULDN'T use them. This article will acquaint you with the same. Voltage Fluctuation Most of the electrical conductors have a threshold to resistance. This resistance increases if the length of the conductor is more. When it comes to extension cords, if the voltage drops during the service end, it might not suffice to run the tool you use. It might operate at a slow and feeble pace and eventually overheat and burn out. If you do not want this phenomenon to damage your devices in a long run, beware of voltage drops. The Cord Chaos Tangles and knots are common even with wires of an earphone. So, it would be surprising if you could use a 100 feet extension cord without untangling it. The best way to avoid it would be wrapping the cord around a reel whenever you use it. But even if you do that sometimes, you might find the cord loosely hanging on a nail or lying across the floor. One more problem with a long extension cord is that it is vulnerable to damage given the length and area it covers. If the extension cord is damaged, it can cause fire hazards. Distance Considerations The name 'extension' power cords itself reveals its ability to extend. However, even if you think that they can always do what they're supposed to do, there are times when you should refrain from using them. This depends on the distance and how far the appliance is. Usually, the thicker the cord is, the longer its length is (length of 150 for the thickest cord). You will rarely see light duty extension cords that are longer than 25 feet. This is because the voltage drops down before reaching the appliance. Result? The device doesn't get enough power and will cause safety issues. This is one of the major reasons why using daisy-chain extension cords is a bad idea. Also, it is better not to install the extension power cords inside the walls as they're unshielded and non-resistant to heat. Power Considerations It is not a good idea to use extension cords for powering high wattage applications like a hair dryer or a space heater. And several appliance manufacturers are against it as you might end up using the extension cord which electric bodies have not rated based on the appliance power. If you use the right cord, you will never face such issues. Let's say your space heater pulls 15 amps. In this case, you will need an extension cord which can cope with 15 amps. So, you will end up buying at least a 14-gauge extension cord and sometimes cords with 11 or 12 gauge too. It is better to avoid using a light-duty extension cord which does not have the ratings for the power draw that heaters need. Make sure you have an apt amount of knowledge about power cords and their ratings before you start using them. If you don't, it's better to seek help and suggestions of professionals. There are several companies that provide extension cords online at cost-effective rates. Ensure that you buy standardized ones for your purposes. This Article is Source From https://www.sooperarticles.com/shopping-articles/electronics-articles/when-where-you-should-not-use-extension-cords-1694372.html A few years you used to buy ethernet cables from brick and mortar stores. And things were just fine. You would just walk in, make your pick and walk out. Until one fine day, you realized that your friends order it online. From within their comfort zone and that too, in a few clicks. You like the idea but are utterly perplexed. Still, you give in to the peer pressure and decide to order for Cat6A Cables online.
And before you know, another confusion pops up. If you specify every tiny detail about the cable you want, the prices you see are soaring. And if you underspecify it, you feel that you would be stuck with underperforming cables. Everyone would want to shop for an ethernet cable that offers good performance at cost-effective prices. So, if you want to ensure that you bring the best cables, you must understand a couple of things. Know About Your Requirements Most of the networks available these days have an option of both, Ethernet or Wifi cables. As you all know, Wi-fi has advanced and it offers better performances with each passing day. But the best part about using these cables is that they provide the users with a superior quality performance, offer swift connections, and have lower latency. Sometimes internet connections weaken the performance and you will observe that even fiber broadband is slower as compared to Ethernet cables. So, if just want to surf the internet, an average ethernet cable will also do. However, the latest the version is, the better. - Cat6A cables are one such example. You might have some old Ethernet Cables but it is likely that they might affect the overall streaming performance. If you have recently purchased a new router, you might find a faster category. Know About the Types Cat 5, Cat 6, Cat 7 are the most widely used cables with CAT5 being the oldest and CAT7 being the newest version that renders high-quality performance. Now, as a different category of cables has different levels of performance, you must select a cable that meets with the system requirement. Check the Device Compatibility The best part about Ethernet Cables is that you can interchange them. Also, they are backward compatible. With the old cable version like CAT5, the only issue is that it doesn't support fast data transfer speed. You can plug a CAT5 cable into a router which has a 10G Ethernet interface. But it will lower the data transfer. This might or might not be a problem based on the file transfer. In the same way, you can end up plugging a CAT7 cable into an old router that might/might not be supportive of latest cable speeds. Hence, there is a lot of flexibility with these cables. Speed Considerations If you want to get the best speed out of your Ethernet cables, CAT6 and CAT6A cables are the best choices. Also, they're perfect for future proofing and do not cost more than CAT 5. It is better not to use CAT5 if you are looking for a good amount of speed as they have become obsolete. As of now, CAT7 cables do not offer more advantage over CAT6A cables. Although, if you want to maintain the speed of network over long distances, they are a good choice. Wrapping It Up... The type of cable you choose depends on the kind of speed you are looking for and whether or not you want to future-proof your home/office system. If you want to buy cables for commercial purposes, do not mind shelling out more. Saving finances at the expense of performance is a bad idea. Over and above all, ensure that you buy from an authentic and popular online vendor.
