Seagull I am not really sure. It seemed like a very very very old projector like 10-12 years old. Not sure as to when LCD projectors were introduced into market, I might just got lucky with this one.
Also it is important to note that my symptoms have gotten much worse lately as during last 4 months I got an extreme burnout due to excessive stress in work and had a strong shock moment when I randomly (long story, I didn't really care and didn't want to know as we broke up 7 months ago, but still it's hard to forget 5 years of relationship so quickly so it had effect on me 🙂 ) confirmed that my ex-gf cheated on me for like half a year (yes, I knew it, but she denied and I had no way to prove it, since she was a very good manipulator). I think this is important, because my nervous system became very very sensitive and I became sensitive to almost everything flickering - LED/Fluorescent lights (these never affected me and I was happy that I had problems only with screens), screens in cars(1 year ago I was perfectly fine with tested cars...), screens/lights all around the city. Before all of this I was feeling perfect most of the time and not looking at screens directly would give me very mild strain/blur, which would go away quite quickly. I could look at people's phones for 5-30 seconds and it was ok.
So to sum up these projectors which worked a couple of months ago, might not work now, thus I am going to resume my projector tests this weekend, with rented Optoma HD27. These tests are not easy as it is hard to find projectors for rent, which are still available in shops. On the bright side - I am renting for short time, thus not losing loads of money for each test. Also most of the companies do a huge discount for renting during the weekend, so there are plenty of time to test the same projector with different devices and for very good price.
