a thought.
I was looking into and bought the Nintendo Switch.
On known good devices I currently use which are eye strain free, watching previews and 60fps walkthroughs induce no eye strain.
After buying the console and seeing it uses an Nvidia GPU, either docked or undocked, there is clearly some dithering which means I can't play more than 20 minutes without developing symptoms.
Presumably a video capture (via twitch) or via a PC bypasses all local GPU processing and we are left with an unaltered image?
Can you watch YouTube videos featuring the latest W10 desktop or Nvidia gaming without problems?
In this case, is there any adapter (pass through) device we could use so that problem devices are 'capturing' the video and outputting it to our monitor?
