That website rtings.com is really quite good, it tells which TV models has PWM and which does not, the type of display panels used, the flickering factor etc.
Many Samsung TVs have PWM, so those are out. LG panels seems to give me eye strain when looking at it at the store. Sharp TVs, somehow I am not keen on how their picture quality looks. So far I can use Sony LED TVs without any eye strain whatsoever. So I am hoping that I can use their newer models also without eye strain.
So far my shortlisted TVs right now are:
Sony KDL-55W650D - 55 inch. This is a 2016 model, 650 series is entry level. Has less features i.e. no HDR, no Triluminos etc. I figured the less graphics "features" there are are, the less the risk of one of those "features" causing me eye strain. The picture quality is ok, pretty good, for an entry level series. I looked at the 700 series (which has HDR and Triluminos), and didnt like the colors so much...a bit too saturated for my taste.
Sony KDL-50W800C - 50 inch. This is a 2015 model. 800 series is the upper mid-range model. No HDR and Triluminous, but really good picture quality. Has Android TV. I looked at the settings, it came with Android 5.1 and the update can be turned off. So at least I dont have to worry the TV getting a Marshmallow or Nougat update. Surprisingly the Android TV seems to be better for my eyes, at least in the brief period of time when I was looking at it at the store. I dont mind getting a 2015 model. I figured, the older the model, the less risk of it having whatever it is that is causing eye strain on today's newer display devices.
Right now I am leaning towards the 800C, even though it is smaller size and older model. Is anyone using any of these 2 models above? Do they give you eye strain?
