I saw numerous laptops with Ryzen/Vega setups at HP and Dell sites. If you are interested in one fire off a question to their tech support to find out if it supports FreeSync internally and or externally. I didn't see it listed in any capacity on either site.
I have already studied all this information, as well as requested the support of all APU Ryzen laptop manufacturers, but the answer to my question hasn't received yet. Therefore, the above question was asked here.
