HDMI and DisplayPort are only necessary for monitors which exceed those specs, such as 4K 60 Hz monitors, in which case DVI is not an option. ports), to prevent VGA adapters from fitting into these ports. DVI to HDMI passive adapters are bi-directional, so the same adapters are used for both DVI source to HDMI display and HDMI source to DVI display. HDMI to DVI passive adapters are bi-directional, so the same adapter can be used both from an HDMI source to a DVI display, and from a DVI source to an HDMI display. There are no active adapters for converting a DisplayPort source to a Thunderbolt or Thunderbolt 2 display. Since DisplayPort to VGA adapters perform active conversion, they will also work in newer graphics cards without native VGA support, such as the AMD Radeon R9 290X or NVIDIA GeForce GTX 1080 or newer. The recommendations listed below all support both DP 1.2+ to HDMI 2.0 conversion, with inline audio and full resolution/refresh rate/color support. They are not bi-directional, so they cannot be used to connect an HDMI computer/laptop/console to a DisplayPort display. Retailers do not usually label their passive adapters as “Type 1” or “Type 2”, so they must be identified by the maximum resolution claimed by the manufacturer.

The models we’ve seen are inelegant, leaving a little nub sticking out of the side of a laptop when the cable is disconnected. We then ran a free system-performance app called AJA System Test Lite on the laptop to measure read and write speeds in MB/s . To test power draw, we used the 13-inch laptop, a Satechi ammeter, and a first-generation Google Pixel phone, and we noted the maximum power-draw readings on the ammeter as well as on the laptop’s System Report. Unlike on Apple’s cables, the plastic housings that join the metal connectors to the Anker PowerLine II cables seem sturdy and robust, built to withstand bending or fraying even with frequent use. Compared with most of the other cables we tested, these cables make a satisfying click when plugged into a USB-C port and have minimal wiggling, ensuring a solid connection. If you have a device with a USB-C port—such as a MacBook or other compatible laptop, an iPad Pro, a Nintendo Switch, or an Android phone—you need a cable to charge it and to transfer data to and from other devices. Unfortunately, when it comes to USB-C, even cables that look identical can behave very differently—for instance, a cable that charges your phone at top speed might be sluggish at transferring music files, or vice versa. We’ve tested 78 cables and 16 adapters to help you find the right one for your needs without overspending.
HDMI to Mini DisplayPort is also available as both anadapterand acable. , also known as Type D. Micro-HDMI is used for especially small devices like cell phones. To easily calculate the amount of power that the RFID antenna is receiving, see the equation below. Length – The longer the cable, the farther the energy has to travel. No antenna cable is perfectly insulated; so, the farther the energy travels, the more energy it will lose. In some applications, the reader is farther from the antenna due to the nature of the application.
In some cases, the conversion between digital ports or connectors is pretty straightforward and can be done by matching and connecting the corresponding wires from one connector to another. USB Type-C is the connector of the future, but the future is confusing. We’ve tested everything you need for your MacBook Pro or other USB-C laptop, iPad Pro, Android phones and tablets, or any other USB-C or Thunderbolt 3 device. We have picks for charging cables, cables for fast data transfer, HDMI or other display adapters, hubs, docks, wall chargers, and dongles. If you have a device or display with an HDMI port of any version between 1.3 and 1.4b, then any HDMI cable with a High Speed certification will handle any signals your devices might send. If you have devices with HDMI 2.0–2.0b ports, then a High Speed HDMI cable may or may not work, since they have only been tested up to 10.2 Gbit/s.
Mac notebooks that charge via MagSafe come with an AC adapter with MagSafe connector and detachable AC plug, and an AC cable. Power adapters for Mac notebooks are available in 29W, 30W, 45W, 60W, 61W, 85W, 87W, and 96W varieties. You should use the appropriate wattage power adapter for your Mac notebook. You can use a compatible higher wattage power adapter without issue, but it won’t make your computer charge faster or operate differently. If you use a power adapter that is lower in wattage than the adapter that came with your Mac, it won’t provide enough power to your computer. We don’t have plans to test adapters that connect wired headphones to a USB-C port, but some of our staff like Apple’s USB-C to 3.5 mm Headphone Jack Adapter, which is relatively inexpensive. To test USB-C–to–USB-A adapters, we plugged the USB-C end into the 13-inch laptop and the USB-A end into a SanDisk Extreme CZ80 16GB USB 3.0 Flash Drive and ran AJA System Test Lite.
I’ve tried it on iPhone 6s and higher, as well as the most recent iPad and iPad mini tablets. Apple uses a different protocol and they don’t mention that on here or even on their tech support when you talk with them. They say Apple devices should work “under normal circumstances”. We always try to ensure our customers have exceptional experiences with us and our products and we apologize for the problems you’re experiencing with our MUYHSMMF. This adapter should work with standard headphones and a microphone on a Samsung phone and we’d like to speak with you further to help get this working properly for you. Please contact us at /support where our Technical Advisors are available 24 hours a day, 5 days a week to provide support. Tuck the adapter in with your tablet or slip it inside another carrying case.
Using these methods, a sink could discover the source is capable of up to 3A. Video converters actively process and change the signal type from one video standard and convert it to another standard. They are typically used to convert digital to analog and vice versa, but can be used to convert a digital signal to another digital video standard . A connector is the unique end of a plug, jack, or the edge of a card that connects to a port. For example, all desktop computer expansion cards have a connector that allows them to connect in a slot on the motherboard. When referring to cables, the connector is the end of the cable that connects into a port. For example, the end of a USB cable has a connector that allows it to connect to a USB port. Thanks for sharing your feedback on our MUYHSMFF audio adapter. We apologize for the confusion regarding what devices it will work with. We’ve made a note on our Technical Specifications explaining how our adapter is configured.

A DIN to BNC Cable used to connect any device with a BNC output to the Pod port input of a PowerLab. Use with Tendon Hammer and any transducer with a BNC connector where an extended cable is required. The Leviton T5635 is the best way to add two future-facing USB-C ports to any wall outlet. HDMI allows a wide variety of explicity defined video format timings to be transmitted and displayed. This claim comes from people reading it on Wikipedia but not checking the citation, which was just a youtube video of some random guy saying so. Speaking as someone who has the actual HDMI 1.4/a/b Specification documents on hand, this claim of 1080p 120 Hz support being introduced in HDMI 1.4b is completely false.
When the HDMI Specification “adds support” for a certain format, it doesn’t mean it in the conventional sense of “adding the capability” as if it wasn’t previously possible. Video formats do not require “support” from the HDMI Specification to work, because the word “support” does not mean what most people think it means in this case. DVI, and display makers have been free to implement 1080p 144 Hz over HDMI ever since then. Yes, existing High Speed HDMI Cables will support the new higher bandwidths . No, these are official names for the various cable tiers, established directly by the HDMI specification. The Premium High Speed certification was added in 2015 as a standalone release , not part of any of the HDMI specification documents. But when converting between two different formats the image quality will only be as good as the worse format. Depends on the adapter, but usually they do not add any meaningful amount of latency.
DVI by setting a custom resolution, but it depends on monitor support and is not guaranteed to work. A straight DisplayPort connection is the preferred option in all cases. , for high-speed USB data transfer over the same cable. 8 lanes of HBR2 (34.56 Gbit/s total); sufficient for dual 4K 75 Hz displays, or a single 4K 144 Hz or 5K 75 Hz display. The DisplayPort version is dependent on the source device. to DisplayPort adapter, since they rely on that capability to operate. source to a VGA display, but not the reverse configuration.
This cable is pricier than most of our picks, but it offers maximum charging power and data-transfer rates when used with compatible devices. Plus it’s an “active” cable, so it can be longer (6.6 feet) than most Thunderbolt 3 cables without sacrificing performance. If you need one cable that does everything, this is the cable to get. It supports fast data-transfer speeds , can output video to a monitor, and can charge any USB-C laptop, even the 16-inch MacBook Pro, at full speed. The above versions of USB, and the Apple-specific Lightning connector, are the focus of this guide. Each has different capabilities and limitations in charging power and speed and data-transfer speed between devices .
