NewerTech Announces HDMI Headless Video Accelerator

headlessHDMINewerTech announced today the NewerTech HDMI Headless Video Accelerator, a simple adapter that plugs into the Mac mini’s HDMI display port to make display-free “headless” Mac minis used as storage and media servers think that there is a display attached. Using the NewerTech adapter, video drivers are loaded and the GPU (graphics processing unit) is fully activated for 100% full video performance with no more choppy images or mouse lags.

Plug It In & Restore Video Performance
Because of the Mac mini’s compact size, superior storage, performance, and low cost, they are often used as “headless” networking, storage, production studio media, and home theater servers with no need for a monitor, keyboard or mouse. When the Mac mini is used without a monitor, its GPU isn’t used. As a result, the interface lags, resulting in choppy screens and slow video, animation, cursor movements, menu navigation, and typing. Plugging the NewerTech HDMI Headless Video Accelerator into the HDMI port of the Mac mini solves this problem, engaging the GPU so your remote interface works exactly how you’d expect.

“In the past, when using the Mac mini as a server, the best option was just to grin and bear the slow video performance whenever you needed to remotely access your mini, which is an entirely inadequate experience,” said Larry O’Connor, President, NewerTech. “With the NewerTech HDMI Headless Video Accelerator, the Mac mini thinks there is a display attached, so you’re back to the 100% silky smooth OS X experience you know and love.”

  • “Maximum Resolution: 1080p.”

    Have you changed the product? The ones I have supported 4K when I plugged it into a 2014 Retina MacBook Pro 15″

    • Hello MacRat,

      This HDMI headless video accelerator does support 4K (UHDTV or UHD-1) with the Late 2014 MacMini (Mac mini 7,1), which has a resolution of 3840 x 2160.

      With all other compatible models (MacMini 4,1/5,1/5,2/5,3/6,1 and 6,2) the resolution would be 1920 x 1080 @ 60Hz.
