HDMI Headless Video Accelerator
Take back the full power of your computer

  • Use the full power of the graphics processor without needing a display
  • Remotely access your Mac or PC with native display support
  • Ultra-compact, low-profile design
Never settle for a choppy interface.
Mac and PC computers pack phenomenal power into a beautiful form factor, but when it's operated without a display attached, the GPU isn't activated - meaning it's not pulling its weight. So when you access your Mac or PC remotely, the CPU does all the work rendering the user interface. As a result, the interface lags; OS animation, cursor movement, menu navigation, and typing all suffer, making remote operations a pain.
Plug in. Restore Performance. It's That Easy.
Now there's an easy way to make your remote experience perfect again. Plugging the NewerTech HDMI Headless Video Accelerator into the HDMI port of your Mac or PC activates its GPU, even without a display, emulating resolution displays up to 1080p, so your remote interface works exactly how you'd expect. Get back to working smoothly on your headless Mac or PC with a NewerTech HDMI Headless Video Accelerator.

Rating: 4/5 Great for servers, not for HTPCs November 16, 2016 This is great for speeding up the performance of headless servers that you want to control via VNC or Apple Remote Desktop. Plug it in, and it activates the GPU (macOS doesn't use the GPU if there is no monitor detected).

I also have a Mac mini that I wirelessly mirror to AppleTV to play media. This does NOT work for that, as video playback drops frames and gets super choppy with this plugged in.

I would recommend this item to a friend! Customer Videos:

Rating: 5/5 Unique, but simple and solves a problem June 16, 2016 This device is pretty simple, so I might consider it to be a little over-priced, except for the fact that is far more convenient and tidier than building my own and as far as I could find, the only device of it's kind that is readily available.

I installed the headless video accelerator on a Mac Mini that I am using as a music server, which I access either from my MacBook Air or iPad, so it has no monitor or keyboard. Without a monitor attached, the screen resolution presented to a remote login was a low resolution 4:3 image with a lot of lag. But with the video accelerator plugged into the HDMI port, I get a full, high resolution image when I login and control the Mini from my Air. Problem solved!

Rating: 5/5 Simple and inexpensive! February 8, 2016 I didn't know this existed until last week. I have been running a monitorless mac mini for quite some time now. Using screen sharing, I have been able to access the mini. However I would always have some lagging desktop problems from the mini's desktop. If i dragged a window, sometimes the screen would turn black as if the window had a shadow.Other times the windows would become fragmented for a few seconds before going back to normal.

After finding this here at OWC. I ordered one right away. The price was just right. I've been a customer of OWC for several years. They haven't steered me wrong yet with previous purchases. They back what they sell and they didn't fail this time.

The adapter arrived today. Powered down the Mini, and plugged the adapter into the HDMI port. Powered up and once the desktop appeared on my main mac, I could see the difference right away. I can actually fill my monitor with this desktop; something I couldn't do prior to having the adapter. Moving windows around is no longer choppy. In fact its rather seamless; very smooth.

Once again I am very satisfied with another item sold by OWC. Kudos to NewerTech for making a simple device that makes a world of a difference. I highly recommend this inexpensive item to anyone who runs a headless mac mini!

Rating: 5/5 Works as promised January 26, 2016 I have a headless mac mini acting as a database server, it was painful at best to access via screen sharing, especially with window redrawing. I tripped across this product at OWC and thought "hey, i need that". Turns out I did need it... remote control via screen sharing is vastly improved.

Rating: 5/5 Does the job January 3, 2016 I ordered this headless HDMI plug to use my Mac Mini as media server and without it the Mac would perform poorly because the video acceleration would not kick in as it wasn't connected to any monitor. Now that I use it the video acceleration is working as if a real monitor would be connected to my computer which is exactly what I was looking for!

Rating: 5/5 a necessity for remote control January 1, 2016 If you do any work with headless minis, this tool is a must. Without it, screen refresh is slow and bazaar - sometimes large blocks of the screen black out and you have to drag a window over the area to get it to redraw correctly. At least this has been my experience on the 4 mini servers I am managing. . . .It's a real hassle and can distract from the task at hand. With this device installed, not only does the "display" operate as you would expect over ARD, but it works in a higher resolution, by default. . . . and I suspect, with Grand Central, the overall performance of the system should be improved too, although I have not tested for that.

Rating: 5/5 Screensharing issues fixed with this Adapter November 20, 2015 I've got 3 Mac mini computers running OS X server each without a connected display. Before installing this adapter I kept having issues with screen sharing: the display would not fully update. After installing this adapter screen sharing works just as it should. Thank you.
