Samsung and Sony released QD-OLED TV without PWM ("only" contains small refresh rate OLED flicker). This relates also to the Dell Alienware 34" inch QD-OLED monitor which also doesn't have PWM.

If anyone reading isn't aware Quantum Dot is a big deal since it doesn't have brightness issues, you can actually run it at normal brightness without huge pain (does this apply to these Samsung TV? There may be other factors at play so I don't know). But Samsung and Sony TV will still have it's TV operating system which could introduce strain.

I haven't decided if I'm going to get the Samsung QD-OLED TV or the Alienware.

Guys, this is totally different technology than the LG OLED which caused pain due to White LED.

Tagging @KM since he brought the White LED brightness issue to our awareness, and I think you will find these new TVs to be relevant to your interests.

The Samsung TV is called S95B.

The sony TV is called A95K

    degen changed the title to Samsung and Sony QD-OLED TV .

    The question is Tizen vs Android?

    I had read about QD-OLED before. Here is a review of the Samsung S95B from a German website: https://hifi.de/test/samsung-s95b-qd-oled-test-93259
    I don't about know the site itself. I don't read it usually, but what I was interested in is the QD-OLED spectrum they show:

    The red line here is regular QLED:

    The red line here is White OLED:

    This is just theory, but to my dismay the QD-OLED spectrum is not shifted to violet. Instead, the blue part starts right where the White OLED spectrum starts. This may be irrelevant after all, but so far I was under the impression that the reason Quantum Dot backlights could in general be less aggressive is the violet shift.
    Only a test will tell for sure, of course.

      degen To me that slow flicker and dip in brightness of OLED and QD-OLED is alot worse than high speed 960hz pwm, thats why I can't stand OLED, I feel a lot of eye strain with it, It is better to have displays with DC dimming or flicker free.

      I also have problems with flicker tvs… (use sony flicker free tvs and dell / lg flicker free monitors)

      I have much interest in qd-oled tv since i had oled tv in the past and had to return it….

      So anyone had buy the s95 or the sony A95k? Does it solves the headaches and eye strain?

      I hope next year we will have a 48-50 inch tv since 55" is to big for me….

      Just wanted to say great post, thank you!

      Has anyone had any progress on this? I just purchased a LG C2 on Friday and suffered through headaches all weekend. I'm trying to decide if I should return it for the QN90B or thr S95B. Years ago I purchased a C7 oled and had to return it also. I was hoping the issue was gone by now because I use a Samsung phone with oled that doesn't bother mean and I also use a dell xls 15 laptop with an oled screen that doesn't bother me. A quick Google search shows that Samsung makes the oled panel in my Dell laptop too. I'm wondering if Samsung does something different that prevents eye strain?

      Just for your information, flickering of the mentioned TVs below. Did you try settings "color gamut" on lowest setting instead of "auto"?

      Seems like you can use the S95B in Dynamic Mode above brighness of 20 without "flicker".

      Returned my 65" LG C2 today and picked up the Samsung QN90B 65". So far it is much easier on my eyes but it is definitely a down grade in every aspect other than brightness. I don't even like my picture very bright so kind of a waste. Something I didn't see coming was the horrible reflection coating on the Samsung. I have a big window to the side of my TV and it's amplified on the screen. Rtings mentioned the "rainbow" effect of the reflection coating but I had no idea it was this bad. I'll be returning it because of this. I also am annoyed by the "dirty screen effect". I think I'll be picking up the Samsung S95B next in hopes that my eye strain is due to the white led's on the LG and not the low flicker rate. TV hunting is so frustrating. It's hard to look at anything now after seeing how amazing the picture on the LG C2 was.

      What TVs available now are considered flicker free? (Besides supposedly OLED as LG is completely out of the question for me). I suppose I should ask more specifically about LCD.

        Looks like I found my answer to why the oled screen on my dell laptop doesn't give me issues. As I stated earlier, I found on the google that the oled on my laptop is made by Samsung and I just found this article stating they they received certification from TUV for "flicker-free". I don't think any of the oled TV's have this certification yet to the best of my knowledge.

          Clokwork Sony X80K(IPS) & Sony X85K(VA) are considered completely flickerfree, rtings tested them.

          • KM replied to this.

            hayder1983 I looked up their X80K review to find that, as usual, their claim is not true. You can see in their own test picture that there is obvious flicker on at least the lowest brightness levels. However, it is true that Sony in general has been known to care more than other TV manufacturers about at least trying to have a steady backlight.

            It is much more complicated though. There are more situations where there could be introduced flicker, e.g. by simply switching channels or having a black picture in between loading screens or movie scenes, and rtings doesn't bother to test those.

            Diamondintherough we have talked recently about how the TUV certificate is surprisingly worthless, as they certificate monitors that use PWM as "flicker-free".

              KM oh, my bad. Well if my samsung screen on my laptop isn't easy on my eyes due to flicker then im not sure what it is. I'm hoping the discomfort from the LG C2 was due to the white leds as mentioned in the original post. I'm working out of town at the moment but this weekend I'm going to bring back the QN90B and get an S95B. I'll let you guys know my experience.

                raven83 Sorry for the late reply, I'm out of town again for a few days but I did use the S95B a lot over the weekend mostly playing the new call of duty on PS5 at 120fps. So far I'm happy to report that the eye strain that I was getting with the LG C2 doesn't seem to be an issue with the S95B. I was mostly using it in game mode but I was also watching some Netflix and Disney plus. The picture is crazy vibrant and damn this thing can get bright for an oled. I've been doing some research all week to try and find some good picture settings because at the moment if find it's crushing Black's pretty hard but I'm optimistic that I can't mitigate this to an extent with better picture settings. My main concern was the eye strain though and I didn't get that over the weekend. I'll be tweaking it some more this weekend so I'll let you know if anything comes up then. I cant say for certain but at this point I'm assuming the eye strain on the LG was due to the white pixels.

                  Diamondintherough thats great news! One of my theorys is the same….could be white pixel…and rtings says the tv is flicker free at a certain value of brightness. Keep us posted of your progress! Thank you!

                  Diamondintherough Hey any updates on your experience with this T.V.? Sounds very promising for those of us who had disappointing experiences with earlier OLED screens despite their promise of being "flicker free." Thanks in advance!
