![]() Most hubs support only a 30 Hz refresh rate (the image refreshes 30 times a second) at 4K resolution, but a handful now support a smoother 60 Hz rate, and we prefer those hubs that do. We connected each of the hubs via HDMI to a Philips 272P7VUBNB/27 monitor with the resolution set to 4K, and we used the Blur Busters UFO Motion Test to confirm the refresh rate. ![]() HDMI: A hub can be very useful at a desk, especially if you want to hook your computer up to an external monitor.Our measured speeds landed largely in the 400 to 425 MB/s range we eliminated any model that was noticeably slower. Most of the hubs we tested advertised USB 3.0 speeds, which max out at 640 megabytes per second on paper. Since SSDs are faster than spinning hard drives, our use of the T5 ensured that the speeds we measured weren’t hindered by the drive. We ran AJA System Test speed tests using the Samsung T5 Portable SSD (500 GB) to measure transfer speeds. USB-A speed: Although USB-A ports generally don’t support data-transfer rates as fast as those of USB-C or Thunderbolt 3 connectors, it’s still important to be able to transfer data quickly.Two USB-A 3.2 Gen 1, one USB-C 3.2 Gen 1, one USB-C power Two USB-A 3.2 Gen 2, one USB-C 3.2 Gen 2, one USB-C power Note that the Anker 10-Port 60W USB 3.0 Hub ships with only a USB-A–to–USB-B cable, so you’ll have to buy a separate USB-B–to–USB-C cable to connect it to many modern computers. As a bonus, it’s aesthetically inoffensive-it doesn’t look like it belongs with the greatest hits of ugly ’90s technology, unlike some of the other hubs we’ve tested. It has seven upward-facing USB-A 3.1 Gen 1 data ports with a helpful LED activity indicator for each it also has three 12-watt (2.4-amp) power ports just for charging. This being said, the metal inside of the splitter's jack will "break in" over time and become easier to use while still maintaining a strong connection.If you’re mainly concerned about connecting to your computer as many devices as you can, choose the Anker 10-Port 60W USB 3.0 Hub. This is because we want to make sure the connection between the jack and the microphone plug is as secure as possible - we know how important audio recordings are to court reporters. The first few dozen times you insert your microphone into the MIC jack of the splitter will require more force than usual. Please note that the MIC jack of the splitter is VERY tight fitting. We offer no guarantee on these splitters when it comes to laptop brands other than Lenovo, however they have been known to work with most laptops as well as most mobile phone devices. ![]() There is nothing we can do about this as it is a hardware setting and is not something we can change. ![]() Some model ThinkPads are known to have reduced recording volume if your microphone is not battery powered. Some ThinkPads that have the combined jack and that are running XP do not work with the adapter, which is a software issue and not a defect of the adapter. This adapter has been designed and tested to work with all current Lenovo ThinkPad computers with a combined audio (VOIP) jack running Windows 7. Once you do this your external microphone will work properly and your playback will run through your headphones. Just plug this adapter into the combo jack, then plug your microphone into the cable labeled MIC and your headphones into the cable labeled HEADPHONES. We have designed this adapter cable to solve this problem for court reporters. However, if you plug a microphone into the combo jack, the external microphone will not only NOT work, but it also disables the computer's internal microphone as well as the internal speakers because the computer thinks there are headphones plugged in. If you plug headphones into this new "combo" jack, they work. The problem for Court Reporters who have these systems is that you cannot use an external microphone with these systems. The reasoning behind this is due to the influx of VOIP (Voice Over IP) companies, like Vonage and Skype, who have developed headsets that use a single jack instead of 2 jacks so that you can use a special headset to listen and speak. The latest computer models from leading manufacturers are following suit with the iPhone and Skype trends by combining the traditionally separate headphone and microphone jacks into a single jack. ![]() Split your combined audio jack into 2 separate jacks! ![]()
