I stated this in another thread, but the ZenScreen didn't work for me. It uses USB-C, but pretty much immediately, I couldn't focus on the screen without feeling overwhelmed and sleepy. It's 1080p and 15.x"

    Clokwork i'm sorry. i am getting some of that too after watching a movie last night, but switching now to AMD to try out 10-bit, which wasnt available with nvidia. i assume 12-bit option will be with FRC

      If you are sensitive to temporal dithering, that might make it worse. I believe that screen is 8 bit natively. Running 10 or even 12 bit would use FRC without doubt.

        Clokwork 10-bit monitors are already rare enough, not sure where one gets 12-bit.

            JTL agreed. Some monitors accept higher than 10 bit, but I assume they use a LUT at that point.

                Clokwork I actually don't know how LUTs interact with dithering (if in any way)

                  For instance Eizo states for their native 8 bit in 8 bit out panels that they use a LUT to provide the best color matching. This has nothing to do with temporal dithering but just a way to output colors. For a monitor that uses 8 bit + 2 FRC, they will do so to meet colors in the 10 bit color space, but if it is fed 12 bit color, it can use a LUT for those 12 bit colors to closely match what the 10 bit color space has to offer.

                  so per their website the $250 Uperfect (QLED-quantum dot) is 10 bit. the cheapest one, which i think i got is 8 bit. I was assuming 10, that since the 10 and 12 bit options showed up in control panel

                    reaganry I am a bit curious about that. I don't see any way that there will be a true 10 bit panel for $250. 8bit+2 FRC for sure, but not native.

                    If there is a choice for using 10 or 12 bit color, I'd highly assume that the use of temporal dithering is being used.

                      I gave up on my USB monitor. i'll keep it for traveling since it seems tolerable. Very excited about my windows 7 laptop.. seems almost perfect- but then my credit card got pwned after only a week using it 🙁

                      ensete I have. While patching, it takes longer for me to feel the symptoms, but still if I use the computer for longer than 1h I get the damn eye strain. =(

                        I have bad news. After the 31.08 updates I have problems using the external monitor as well.

                        Unfortunately in Accenture they forced the updates every week. There were not windows updates but many intel drivers. I restored the GPU drivers to the previous version but it must be something else that did the damage.

                        Crazy, all it takes is one update to destroy a perfect setup.

                            denise_eca Did you buy the glossy touchscreen one ? I have it too ( Uperfect Y ). It's pretty comfortable but there's a little flicker on it + it is 6 bits color depth ( i don't know if it's FRC or not ).

                            It gives me eyestrain after an hour or so !!!

                                Allekss Yes, it's more comfortable than my macbook screen, but still I get some eyestrain if I use it for longer than 1h

                                  I can no longer use the monitor with USB-C after that intel upgrade. However, I found that I can use it without eye strain with HDMI.

                                  So try to use both connections.

                                    Clokwork Which macbook did you use with it? (or pc). Which color profile did you use with zenscreen? Have you applied differing off terminal commands ? Have you tried betterDisplay app also? - The reason I'm asking, since you need to tackle the beast one by one. I would really want to find out whether zenscreen emilinates PWM flicker cause, and the rest could be handled by all these workarounds, including tunring off font-smoothing.

                                    Then if it all works, you go go headless with macbook air m1 for example, snapping off crappy screen.
