owmyeyes is this display driver alone the reason that works for you? or both driver & this specific monitor in combinations?

as @machala mentioned above, have you tried different monitor using USB to HDMI with displaylink adaptor using same software driver in the settings? this is to rule out - this specific monitor

macsforme My cellular network is 4G LTE and I have not yet upgraded to 5G networks.

This issue which I mentioned in the post is from broadband wifi router's 5G connection to Apple macbook pro or iphone 15 phone

ensete hey this is my work laptop - Macbook Pro M1 2021 model. I use extensively for coding and web browsing (Mostly texts and images and not videos).

My network is fiber broadband connection. Wifi Router is Tp-Link with wifi network of 2.4Ghz & 5Ghz. Router is configured to have 2 separate wifi ids. Speed from 2.4Ghz connection itself 40-50 Mbps more than enough for my work requriements. 5Ghz connection speed is in the range of 150-200 Mbps which thankfully I don't need it for the time being.

hey my symptom is not eyestrain or headache or pain in the eyes. Symptoms are neck and shoulder pain. Difficult to focus the screen.

Just rule out its in my mind related, I asked my wife to connect network discreetly then I tried to use the laptop. Whenever laptop is connected with 5G wifi network, I immediately got the symptoms. If laptop connected to 2.4G wifi network, everything normal. So this is definitely not my mind related.

Anyhow I am not going to scratch my head on this anymore. I will continue to use 2.4G wifi, avoid 5G altogether and carry on with my work and life.

If you are not having these issues, then you are good and blessed with good genes maybe. But don't undermine my sufferings. its real and not fake.

Just shared this post to know if I am alone or anybody else also have this issue.

I am from India, suffering from LED strains for last 10 years. You can find various posts from me on this forum how I am managing these symptoms.

Symptoms - Neck pain, Shoulder pain, brain fog, difficult to focus the screen, elevated heart beats

For the last 1 year, I was able to manage the symptoms with Old ccfl monitor Dell u2410 with blue light blocking AMBER glasses with my Macbook M1 work laptop. This setup was savior for me.

Recently this good setup started giving me issues again. Troubles started with my phone (iphone 15) as well.

When I investigated what changes in recent times, I found out that I upgraded my Wifi and Mobile phones to 5G network. Realizing this, I reverted the network back to old 2G wifi router, surprisingly my symptoms disappeared, felt better with the old 2G router networks.

Summary - somehow 5G signals may interfere with your good setup and make it worse. Please post if you also encountering similar issues with 5G.

one bad news! All of a sudden my good setup (M1 Macbook + CCFL Dell U2410 + Blue light blocking Amber glass) is giving me neck pain and eye strains. I was using this for last 12 months without any issues.

What changed?

My work laptop Macbook Pro M1 recently updated to 15.2 (Sequoia). Ever since this update, I am facing this issue.

Previously it was macOS Sonoma. It was good and no issues with the setup - Dell u2410 + Amber glasses.

What's next?

Play with different settings and find optimum one.

Update -> My issue got fixed now. It was due to 5Ghz new wifi connection. Moved back to 2.4Ghz wifi connection. My issues got resolved.

hey, I heard that CCFL lights emit more UV radiation than LEDs. Prolonged exposure to UV-A light causes wrinkles and other skin aging problems.

Do you have any idea about this?

CCFL monitor with blue light blocking glass is comfortable for me, however I am worried about UV exposure from the old monitor bulbs. I am using it for last 1 year and have not found any issues however wanted to be on the safer side.

Hi @Firemaker , I have found some better setups or ideas so I'm not using the video capture card approach right now.

I tried the video capture card approach sometime back with my Apple M1 MacBook work laptop streaming into my good windows personal laptop setup through video capture card with OBS. I found that this reduced my symptoms and manage my work. Please note that it was not complete relief. I used very basic video capture card. I agree that screen was bad. It only support 30 fps so latency will be there. But my work involved only coding, web browsing , zoom calls. No video or display depending work. Initially I struggled to adjust to low latency. But after few hours, I have got used to it. So the latency was not a big problem for coding and browsing.

I'm from India. I used this $10 card.https://amzn.eu/d/j5aMsgD

My suggestion - use very basic card and check how you feel. Just check the eye strain part. Don't worry about the latency or screen quality.

If there are no eye strain, you should start using it and few hours of usage, you will start adapting to latency and screen quality issues. If you feel the strain at the beginning itself, try different OBS studio settings and check.

My experience is that don't spend too much money because any setup works initially might end up not working later because of some os updates. Every person is different. Setup works for a person might not work for others. So try different approaches for yourself but with minimum costs. Once you find a working setup, stick to it and don't modify anything on hardware, software level.
