Hi all

Started a new job only to have serious issues with headaches and nausea from the screens. I've know for maybe 7 years I'm sensitive to newer screen technology but I thought I had figured out that a flicker-free IPS screen worked well without issues (both mine and my husband's IPS laptops from 2017 and 2018 are fine). Now this new job has given me a Dynabook Satellite Pro C40-H and a 27" Asus EyeCare monitor and I get so nauseous and shaky with a headache after looking at either of them for only a few seconds (HDMI connection). I tried connecting the work laptop to my old Acer and Samsung monitors from 2011/2012 (CCFL backlights) that usually don't give me problems but they suddenly do too! (I used a hub that allows me to go VGA to USB-C). I also tried wirelessly casting my work screen to my personal laptop which again now causes problems. Does anyone know why the old monitors cause issues when connected to the new laptop? Or when casting to mine? Is there any way around this? A different adaptor? A different monitor or Dynabook that might work for me?

The resolution is set to 1920 x 1080 and refresh rate is 60hz.

Thanks all

Something we all dread happening.

Are you testing these out at home or in an office? Lighting can have an effect, potentially its your office lights causing the problem.

What is the spec of the laptops you can use, do they have graphics cards, or are they all using intel integrated graphics?

Are you sure your laptops have IPS screens? you can test by viewing it from different angles. If its TN the colours will invert when looking at it from below.

Do you have any non-vga screens you know you can use okay? vga can flicker as its analogue due to electrical noise affecting the signal (the vga cable effectively acts like an old tv aerial). My modern work laptop is lightweight and plastic, so emits more electrical noise making an vga connection flicker, but my older chucky laptop is okay.

    Is the OS version the same between the old/good laptop and new/bad one?

    Testing it out at home, this is a work-from-home job. Mine and my husband's laptops are IPS screens for sure, we purposely picked them for that reason. Mine is a Lenovo Thinkpad e570 and my husband's is a Lenovo Legion Y530. Specs are as follows:

    My Thinkpad:
    Intel Core i7-7500U Processor (4M Cache, up to 3.50 GHz)
    ●  Windows 10 Home 64 English
    ●  15.6" FHD(1920x1080) IPS LED Backlight AntiGlare Black, 60hz
    ●  8GB DDR4 2400MHz SODIMM
    ●  NV Geforce GTX950M 2GB

    His Legion:
    ●  Processor: Intel® Core™ i7-8750H 6 core Processor (2.20GHz, up to 4.10GHz with Turbo Boost, 9MB Cache)
    ●  Operating System: Windows 11
    ●  Display Type: 15.6" FHD (1920 x 1080) IPS anti-glare, 300nit, 60Hz
    ●  Memory: 16 GB DDR4 2666MHz
    ●  Hard Drive: 256GB Solid State Drive PCIe + 1TB 7200 RPM
    ●  Warranty: 1 Year Depot or Carry-in
    ●  AC Adapter: 170 watt AC
    ●  Graphics: NVIDIA GeForce GTX 1060 6GB

    I cannot seem to confirm the details of the work laptop (Dynabook Satellite Pro C40-h) as it is heavily locked down by admins. Not sure if it is IPS or flicker free or what graphics card it uses. The resolution is 1920 x 1080 and refresh rate is 60hz and it is an Intel core i3 running Windows 10 pro.

    So the ASUS monitor they provided does not cause issues when hooked up to my personal laptop. Only when connected to theirs! (Same HDMI cable). Are there settings I should change maybe? It is a 75hz monitor but I changed it to 60hz so it matched the laptop (and it is what I'm used to). I tried maxing blue light filter (which does nothing) and brightness is at 100% (to eliminate possible PWM).

    I might try one more new monitor (BenQ) that does not use FRC as I am wondering if that is contributing to my problem.

    I get that the USB-C to VGA connection may be causing an issue. It is just so weird that the problem translates through when wirelessly casting to another device that does not cause any issues on its own.

    I am checking if the company can provide me with a different laptop. Working all day today was not fun.

    Thanks for your help.

        I can't see anything specific here to point to. Your good laptops have additional GPUs, in a desktop they could cause dithering, but normally in laptops they don't because they work with the integrated intel GPU. Your laptops could be different, or things could have changed though since I last looked into it. I can only guess there is something odd about the OS in your work laptop.

        I would suggest trying it with a wide variety of monitors. I have in the past found there is no one good monitor for me, it depends on the system I am connecting it too.

        Spector Is your good laptops on Windows 22H2?

        The other thing that jumps to mind is your work laptop uses Intel Iris whereas the Legion/Thinkpad use Intel UHD graphics.

        Does your company have "older" laptops lying around they might be able to give you? Ask for a older used one, if they have it.

          hi @Spector did you ever find a workaround? How are you doing nowadays?
