Review on Enhance Your Arcade1UP with VSDISPLAY Audio Controller Board 17", ‎M.NT68676.3 by Rick Mcintyrejr

There weren't any instructions either, although it's pretty basic, there are a couple of buttons on the device that would be really helpful, and there's also a way to change the volume, which is a must-have lest your stuff gets too quiet. My biggest complaint is that I found the same board on ebay or Allie Express for $8 after shipping. Sure, you get the Revain guarantee here, but is it really worth the extra $20 for that guarantee? Probably no. If you are not on a budget then this thing is definitely good and it does what it advertises very well. When there is a lag it's barely noticeable and I'm playing in 4K 165 Hertz.
