  • ThackeryBinks I also haven't found any LED-backlit IPS screens to be comfortable. I have an old CCFL-backlit Dell IPS screen which is OK. I've seen a few TN panels in store and a few actually looked more comfortable than their counterparts. In particular the BenQ GL2760H (looks like the TN counterpart to the GW2760HS) looked very still, despite being native 6-bit. Of course, I've learned that viewing a screen for a short time in the store isn't at all indicative of what you'll experience over the course of a few days, where minor strain adds up.

    That's why I'm focused on VA panels right now (and plasma, I like my deep black levels). I would take another look at TN before I went looking for IPS, after my horrible and expensive experience with the HP ZR2740w PWM-free monitor.

    • ThackeryBinks Oh I don't use that monitor very much (I use my Macbook Pro with AMD graphics at the moment)

      But when I do use it it's fine.

      Looking into a 2.5 or 4k monitor for myself as something more permanent that will keep me happy for a while.

        So the new model Slacor was talking about uses 6bit+FRC. Will attach email and datasheet later.

        Hi JTL,

        I grab this from the data sheet - Colors 16.7M (6bit + Hi-FRC)

        I have attached it

        Let me know if you have any questions.

        Regards,

        Hello

        I'm just wondering if the ViewSonic VA2465smh uses a 6-bit or 8-bit color depth, and if it uses dithering/FRC technology for 8-bit.

        Thanks

        • ThackeryBinks The dithering exe for for Intel cards. And regardless I have ideas of something "more permanent" than an EXE for Intel Cards to control dithering/PWM

        • Man, one thing seems certain. Although many of us have the same symptoms, it seems like the causes are all over the place! Everybody is different...

          I just ordered a pair of TheraSpecs Over RX on Thursday night that utilize the FL-41 tint. We'll see how that goes. Normal yellow-tints like Gunnars don't seem to do the trick for me.

          I still think my issue in particular is due to the light source. 0% brightness and f.lux set to 5000K equals symptoms way down on my Dell U2410.

          You might find the onyx book ereader android tablets useful. They use e-ink screens, which prevents using them for video, and can make web browsing tricky - but are great for anything primarily text based and about as eye friendly as it gets. I'm thinking of getting one to use for word processing (I'm a student). They are very pricey though for what they are.

          Might also be worth waiting around for amazon to release an electrowetting kindle/tablet. Its a new technology so can't say how eye friendly it will be, its in the same vein as e-ink but has good enough colour/refresh rates to display video. It doesn't use polarising filters, and doesn't need a backlight to work - so its a good bet it'll be easier on the eyes than lcd/amoled tablets.

            It was marginally better, but not enough to justify the cost (and reported reliability issues). It didn't noticeably dither though, but it transpires I'm ok with dithering.

          • After using this monitor for about half a week, I have to say this is much better then my Dell U2414H.
            It's semi-old tech (DVI and VGA only!) and has some ghosting, but I'm becoming nearly symptom free which is phenomenal.
            We'll see how it progresses.

              Looks like amazon is getting ready to make some electrowetting display e-readers. If you aren't aware, electrowetting technology has similar characteristics to e-ink; low power, can be used without a backlight - however electrowetting has a refresh rate comparable to lcd and good colour replication.

              I'm not that excited about an e-reader (will probably buy one though), but this is a step closer to getting electrowetting smartphones and pc monitors that do not require backlights.

            • I've been doing some research, and determined that all the screens that cause me migraines use polarizing filters in some form.

              Migraine/headache list:
              IPS LCD - uses polarizing filters
              TN LCD - uses polarizing filters
              AMOLED phones - uses polarizing filters (to reduce reflection/increase perceived brightness)

              No headaches list:
              Plasma
              CRT

              Might interest some, due to this I might try out a DLP projector - as they also do not use polarizing filters to produce an image.

            • vinkenvvt Well she doesn't have this problem to begin with 😃

              After she bought it I hooked it up to her awful HP laptop over HDMI that has AMD graphics and I worked on it for over an hour, it's fine.
