Looking for inexpensive goggles that my kids (or anyone else) can use to see video feed from smart controller (from 2S) - I believe it provides 1080p output over HDMI with fairly small latency (which is fine). Another use case is - maybe I can use this for FPV view along with visual observer nearby, if it works well. I know Epson fance glasses may be used as overlay, but not looking to spend $800, preferably under $300...
