I have a hard time finding TV's tat do not trigger eye strain headaches. I have a Panasonic Plasma that when hooked up to my TiVo HD, works find. However if I use a Roku or Amazon Fire stick on the same TV, I get an eye strain attack. Same settings, same display, same input ort, one hurts me, one doesn't.
Also, streaming content through my Tivo hurts me as well. Output from the Tivo HDD, fine, output from streamed content, not fine
Any newer Tivo, Roamio or Bolt, and instant eye strain headache. Remember this is with ZERO changes to settings or adjustments to the screen. This is still a complete mystery to me as to why that happens.
Got LED, it depends on the TV. I found a Panasonic LED TV that when set to GAME mode, which makes everything really bright, causes me no problems when watching my Tivo, OR watching streamed content from the TV itself (it is a smart TV). However, hook up a new Tivo Roamio or Bolt to the same TV, same HDMI port, same settings, same everything, instant eye strain headache.
It is so mystifying, I have not done much reasearch on the topic. Obviously whatever is actually driving the screen, and not the screen itself, plays a large part in all this
