Microsoft had a great/inexpensive wireless 4K adapter. Of course they killed it. Rumors of a replacement coming out later this year but who know.
Many TV/Displays can be casted to directly from your PC now. Not all of them and those that do work aren’t always a stable connection.
IOGEAR has a product I want to try but it’s currently on back order at CDW.
