ShivaWind jasonpicard Well I've been also testing TV's for the last 2 weeks. I bought the lowest quality new Samsung TV, which did not cause me issues at my parents summer house, but the one I bought did. Even though there are screen lottery with samsung screens - you do not know if you will get IPS or VA panel - I was lucky to get the right one, but the problem was the source not the screen. My parents watch IP TV, which never caused any issues. But I need TV just for movies, gaming purposes, youtube - so I attached laptop. No matter the settings on laptop and on TV, it caused my eye strain, blurry vision and some headaches after 20-30 mins.
So I thought it might be good idea to exchange this TV with my parents TV from their home - 2013 Sony bravia LCD TV (edge LED backlight), which was always good to me, no eye strain at all for years. So I did, but instead of IP TV, which does not cause issues I attached the laptop (I tried 3 different laptops) just to watch youtube and it caused me the same eye strain.
This situation got me frustrated, so I bought used Samsung plasma TV and attached laptop to it. I can see the flickering very well, especially on white background. It does cause very light eye strain, which makes it one of the most usable screens, but still it is not as comfortable as my CCFL monitor, as I get blurry vision on my right eye next day. I don't care about it much for now, but then I made experiment - attached XBOX ONE S - the screen changed flickering in some way (I think it was horizontal with laptop attached and became vertical with XBOX selection screen) and immediately caused eye strain. So even with plasma the source is very important, so it's always worth checking what ae you actually watching through that TV.
As this is no go for me I will rent a couple of DLP projectors. in my last job they bought one and attache XBOX ONE, I never got any eye strain or headaches after playing it for 30-40 minutes, so I guess projector will be my only option for now.
