the aoc q24g4e (q24g2 suggessor) uses the SG2381G01-3, the same 1440p180hz panel as the ktc q24t09 and sanc g52. it was mentioned in a review where the back was torn down and the model of the panel was revealed. it seems to be 8+frc since it does hdr10 yet 10bit native is rare

I find it hard to trust ANY monitor at this point stating it is true 10-bit. Simple skepticism. I don't have proof to prove them wrong, but Everything I have checked claiming either HDR, P3 color, etc.. is all natively 8 bit.

    Clokwork I agree. ViewSonic says true 10bit on one of theirs but when asking them over support they first said yes 10bit but then said oh it's 8+2frc. even the up2720q dell which says true 10bit which I'm not sure if that's true either. LCD replacements online say 8+2 for that model. I guess someone would need to tear it down to see if it's true 10 based off panel model.

    I think OLED or maybe some larger sized LCD panels like 30"+ would be higher likely to be true 10. Wish all this was easier to figure out. I called uperfect out for claiming true 10bit on one of theirs and they ended up changing their advertising to 8+2.

        jordan if OLED is true 10 bit, as I’ve read in some places, I’m afraid I don’t know why I suffer watching OLED panels. For my sanity’s sake, I hope current OLEDS use FRC heh.

            What's the best monitor in terms of high strain from that list in sizes 25-27? Specifically from Asus?

            Clokwork Because there are more important things which affect eyestrain than bit depth and FRC.
            Namely, the brightness flicker every refresh cycle and color gamut impact more people.
            All OLEDs have this for now, for unknown reasons to me (a few speculations have shown up but nothing concrete)
            I assume the information is out there somewhere in patents, books, articles or studies but I haven't come across them yet.

            This is what i'm talking about.
            This is a very apparent drop in brightness which can easily trigger eyestrain in people.

                Thanks for your help. I checked the panels from LG (they are actually 6-bit). Updated the table.

                Acer VG252QXbmiipx 240Hz = LG LM245WF9-SSA2 (6bit+FRC)

                Dell S2522HG 240Hz = LG LM245WF9-SSA3 (6bit+FRC)

                ASUS VG249QL3A 180Hz = LG LM238WF6-SSA4 (6bit+FRC)

                LG 24GS60F-В = LG LM238WF6-SSA5 (6bit+FRC)

                qb74 My iPhone X is OLED and gave me no problems all the way up to iOS 15. While OLED (well, AMOLED I believe it was) in that case wasn't the entire issues, the drivers behind them certainly can make a world of difference.

                  Many times they asked (me) to look at MSI G244F E2 "with my own eyes" (to find out the reason). Why does the monitor (in people) eye burner? As a result (for my own) I made a table. Honestly, the (8-bit) HKC SN238CS04-1 panel (on any monitor) just "burns your eyes." I don't know the reasons (the same for 165/180Hz). It feels like a 6-bit matrix (+ Hi-FRC). It was the same on the (6-bit) AOC 24G2SP. (I suspect) that the situation with LG's "pseudo 8-bit" FullHD matrices is (again) repeated.

                  I write here (first of all) my personal feelings. What happens (when you look at the screen). When the backlight flickers, I feel how (gradually/or sharply) the muscles on the forehead strain. With low PWM (2000Hz), light tension (for the eyes), which prevents the eyes from concentrating (on the screen). Cheap monitors (24 inches) FRC + PWM simply "burn out their eyes" (in a couple of seconds). I checked the monitors near the house. (Hopefully) at least someone will benefit.

                  There are questions about parallel (grey) imports. For example, the backlight on the Samsung G7 Neo (from Kazakhstan) will be "velvet" Flicker Free. On the second (same) Samsung G7 Neo (from the United Arab Emirates), the backlight flickers. Problems (maybe) when choosing a "Chinese brand." On a cheap Thunderobot LQ27F180L-Q (up to $250), a simple backlight (via a high PWM). At high brightness, the screen is "nice to watch." When you make the brightness lower (you want to throw the monitor out). More expensive Thunderobot LQ27F240L (for $350-400) will have a better backlight / at low brightness (also) the screen backlight will be more pleasant (for my eyes).

                  I got LG panel, comfort panel to use in 60hz. In 75/100hz it show vertical lines similar as xiaomi mi 2k165hz 27" did at 46hz and above. Not sure but vertical lines could be artifacts due of FRC and refresh rate desync. Difference of eye-strain between 6-bit or 8-bit input, is minor, red color is more intensive compared for old benq2420z. Better to use with DP cable than HDMI (idk why). Monitor can detect 16-235 / 0-255 input range. The color temperature at default is very good - 6000k. No PWM detected in 100...20% of brightness. I prefer to use In 70% of brightness and -2 LowBlue value and 4 sharpness, it shine at 200 nit
