Reversible USB can also connect your 4K screens




The next generation of USB connectors might extinguish the need for dedicated display ports. The Video Electronics Standards Association (VESA) recently announced that DisplayPort technology will allow the upcoming Type-C connectors to relay audio and video signals, with the potential to drive monitor resolutions of up to 5K.

drive monitor resolutions of up to 5K
This is accomplished through the Alternate Mode extension detailed in the USB Power Delivery 2.0 specification, which permits non-USB signals to be sent over the connector. The DisplayPort Alt Mode will be able to use one, two, or four of the Type-C's USB SuperSpeed lanes to transmit DisplayPort signals, while still allowing data and power to be transferred. AnandTech writes this creates room for devices that can use this functionality in "a fashion similar to ThunderBolt" but with "the closer co-operation of the USB-IF and the superior Type-C physical layer." Coupled with its ability to transfer high-wattage power, the Type-C could potentially become a true single cable solution.
According to a press release from VESA, it will even be possible for devices supporting DisplayPort Alt Mode to drive a HDMI, DVI or VGA display through the use of appropriate adaptors. The feature could also prove advantageous for space-starved laptops and tablets that could eschew dedicated video ports for the new multipurpose USB. Unlike Apple's Lightning connectors, however, the new connectors aren't on the market just yet, but production for the reversible USB connectors looks to be imminent with the completion of the Type-C specification last month.

Apple Launches Web Tool to Deregister Phone Numbers from iMessage

Apple today released a new web tool for users to deregister their phone number from iMessage in the event they switched to a non-Apple device. To deregister a phone number from iMessage, users simply enter their phone number in Apple's web tool, receive a free text message containing a code, and submit the code to complete the process. Users who still have their original iPhone can also transfer their SIM card back to the device and go to Settings -> Messages to turn iMessage off. 


Users switching from an iPhone to another device were often unable to receive SMS messages from another iPhone due to their phone number still being linked to iMessage. These specific errors with iMessage have been a well-known issue since 2011, which is when the messaging service debuted with iOS 5. They were also made even more apparent this past May, where a server glitch caused widespread message delivery problems. Apple was even sued over the matter in a California court, although the company cla…

Microsoft acquires iPhone email app Acompli

Apple will disconnect ‘obsolete’ first-gen Apple TV from iTunes in May

Apple has announced today it will drop iTunes support for some older devices from May 25. This includes the first generation Apple TV, and also any PC running Windows XP or Vista. The company is introducing new security changes which will prevent those devices from using the latest version of iTunes.
Apple says that the original Apple TV is an "obsolete Apple product" and will not be updated to support security changes. Only those with the second generation of Apple TV or later will be able to access the iTunes store.
Windows XP or Vista users won't be able to use the latest version of iTunes, but older Windows computers can still use previous versions without support from Apple. Those who do so, however, won't be able to make new purchases or re-download previous purchases on that computer. If you're on on XP or Vista, you'll need to upgrade to Windows 7 or later to continue using iTunes normally.
The writing was already on the wall for these devices: Wi…
