  • "Active" is the key

    Posted by Mark on May 3rd 2019

    Well made product that does just what it says. Longer HDMI cables don't work with my new ($2300!) MacBook Pro. This active dongle fixes the problem.

  • Works As Advertised. 4K at 60 Hz!

    Not much to say other than this does exactly what it says...
    I was getting only 24 Hz over HDMI using my MacBook. The lag was unbearable. I bought this and it fixed the issue right out of the box. Performance was snappy, and I was able to confirm 60Hz using an app I've used for years that lets set custom resolutions and shows you connection information.

    Hadn't used Uptab before but will for sure now. Like Monoprice they make high quality products that do what they're supposed to while keeping the price reasonable... Exactly why I always try and buy from the manufacturer instead of shop on Amazon...
    Thanks Uptab. Good stuff!

  • Awesome

    This thing rocks, legitimately does not degrade a 4k 60Hz signal in any way. I tried another brand's adapter first (same advertised specs), and it was obvious they were using some kind of compression trickery resulting in a blurry 4k signal. Not the case here! 100% legit, would recommend to anyone!

  • Great Product Exactly what I needed.

    Works with my Apple MacBook Pro 2016 15" with Touch Bar. Finley I can get 4K at 60Hz :)
