Although 50 is a good size (not too big, not too small), those of Sony use VA panels and from my experience they have very poor viewing angles. I have a 50x89j and I cannot use it more than an hour or two and can't work on it.

Plus that my model flickers on the oscilloscope ant brighthess below 15, and that's a little much. To counteract that I decrease the contrast, but, because of it's very poor angles, from wherever I look at it, part of the screen is dim and part is bright.

nogahorovitch a)  large (in terms of length and width)

b) bold (thick)

Those can be adjusted from Windows in scaling and font type.

I did however find the 55x80j in the showroom worth a try. But I cannot do that because their system refuses me to return anymore.

      nogahorovitch I had that tv and I had to return it because it does have pwm, rtings.com said it is flicker free but its not true, I felt eye strain and nausea after a short period of use, and I didnt like the panel very much, it have screen door effect, you can see the pixels at medium distances.

          Oh, these are bad news for me.

          I'ts very important for me, if you can elaborate more, why do you thinj that it does have pwm?

           

          Did you measure with some measuring device, or cased on your reactions  of nausea, etc ?

           

          I thought to buy this screen, based solely on rtings.com, who say it is the only TV with true DC dimming.

           

          I would be very happy to receive any information.

           

          I need 50" with true pure real DC dimming, with no PWM that kicks in at low brightness, no PW, at all, including no high frequency PWM.

              Thank you.

              Viewing angles are less important to me because I only sit in front of it, not from the sides.

              I would appreciate it if you could elaborate on the reasons why you can't work more than an hour or two on the 50x89j?

              .

                  nogahorovitch The image is not uniform from neither angle, there's nothing you can do to avoid the low spot-bright spot.

                  The older versions were detected to flicker only below brightness 5, now it's 15.

                  Whith all theese, and all the image proccessing disabled, it's still not a work setup. To me, after a while, it gives the sensation of want to change the picture, anything, as in no peace to the eyes when watching it, the burning need to do something and dry eyes.

                  Maybe it's because of the high brightness not able to be uniformly masked by the crystals, maybe the dithering. The pwm is measured and not present at 15 and above.

                  Btw I'm looking too for a setup, tv or monitor of 50 for work and so far I've found none. I had an old 55 Sony TV that I could use for long periods, it gave mild to medium headackes after a while, but I can clearly remember that the eyes were moistured. Model impossible to find anymore.

                  I recommend to try older models from 2015ish, I once found one in a pawn shop, flicker free, didn't pick it because of poor color representation

                      nogahorovitch All my monitors are flicker free because I am very sensitive to pwm flicker and that sony 50x85k gave me eye strain and made me dizzy, I tried various brightness levels until 16 and all were the same to me, the configuration I used was HDMI in enhanced format, so I can put the 3080 ti at 8 bit full range RGB, I am not sensitive to temporal dithering but that configuration its supposed to disable it in 8 bit panels and up, I not used HDMI enhanced dolby and VRR because the dizziness was stronger even with gsync disabled, I used 4k at 60hz because 120hz cut the vertical resolution in half and the dizziness was worse, also I disabled power saver, light sensor and used game mode without any black enhancer like advanced contrast enhancer because it is like a frame dimming and the backlight flicker more, hdmi signal at full range, adobe rgb color, motionflow disabled, color expert 2, HDR disabled, and I remember everything else at default, I think maybe the LCD matrix have some kind of flicker because for being a VA panel it does not have almost any black smearing, something strange, almost like an ips panel, maybe if you want to try it you can buy it from amazon and take it out of the box trying not to brake any package plastic from the legs or anything and using another sony control, so you can return it easy without any problem.

                        Please if someone can direct me to a link where there a measuring is documented, so to know whether Sony x85k have PWM at below 15 or not ?

                        I have to have definitive data. I thought RTING test thoroughly.

                        RTING repeatedly claims that there is no PWM at all, and only DC dimming.

                        Second, do you know if Sony x80k (which have IPS panel) has PWM below 15 ?

                          nogahorovitch I think the only option we have is to buy from a place were we can return the displays we buy to test them, people have different levels of flicker sensivity, maybe the x85 will not bother you at all, rtings measure pwm, but tvs have a lot of processing options that can introduce pwm and rtings only measure the tvs by displaying a white color but they dont specify what settings they used on the tvs to do the measurements, even when rtings say some tvs are flicker free most of the times they are not, you can realise that by looking closely at their own graphs, the only tvs that I saw are flicker free by rtings measurements, are the toshiba 55C350 and the lg 65QNED90, we only have to know the settings the tvs were at.

                          .

                              Abeabe I don't understand how you circled the Sony but not the Toshiba. I don't see any difference between the Toshiba and the Sony's on the 50% graph.

                                  Sunspark Yes there is a difference, if look closely at the image, the line at 50% in the sony 55x85J is not completely flat, the line is made of some mild valleys or very wide spikes, it is easier to see if you compare it with the graph line underneath.

                                    nogahorovitch using an oscilloscope and a photodiode, as discused here on another thread. I highly recommend a portable one for convenience and practical reasons. It can detect LCD inversion, too.

                                    As a warning this method does not fully validate good screens but rather the bad ones or their settings, as it cannot detect dithering at all

                                      Sunspark I see no difference, either, as no line can be totally flat with today's technology.

                                      For me, that Toshiba seems like a good candidate

                                          Alyosha2001 Yes the oscilloscope line can have micro jitters as perfect flicker free led lights does not exist, but the line should be flat across all the graph and not fluctuating like the sony one does, because that in milliseconds is perceived as flicker.

                                            I think those can be errors of measurement. If we could see the whole graph and not just 20 msecs, than we could see if there is a periodicity or not. I think they are just random and too small in amplitude to matter. Compare it to a pwm and see how they differ.

                                            It can be a less perfect current driver, a flawed model, etc.

                                            More importantly to me is if they were to measure the dithering.

                                            The line in the toshiba 55C350 graph doesn't seem flat to me.

                                            Also, it is not good as a PC monitor. "can't display proper chroma 4:4:4. This is disappointing if you want to use it as a PC monitor and want clear text" https://www.rtings.com/tv/reviews/toshiba/c350-fire-tv-2021

                                            Is there a better option?

                                            I'm really desperate to find a 50"-55" TV that its line is completely flat line, totally flicker free, in all the settings and brightness levels.

                                            Also, is there another site that makes measurements, like rtings and even more thoroughly than them?

                                              If you can, give the 55c350 a try. It consumes a little too much current, but maybe just at full specs. However it is it is a pretty rare thing to not have pwm.

                                              In my country it is unavailable, so I cannot help.

                                              Flatliners do not exist, just good enough to do the job ones.
