Graphic cards and stomach ache (heartburn, reflux etc)

Aquila

Hello guys in the last months I tried many GPUs in a safe Win10 OS (1809) and monitor Hp X27i.

2070s my main GPU, no issues with good OS and monitor. (Nausea with Benq EX2780q and bad windows 10 OS)
-1660 super , same feeling but I need more test.
-Arc A770 le, migraine and tinnitus probably the coil wine triggers bad feeling.
-1080ti Initially I was good with this GPU, but during long test and gaming sessions I experienced stomach ache and reflux, but not migraine or eyestrain.

Is it possible that a bad GPU could causes these issues?
What symptoms did you developed with bad GPUs and monitors?
Thx

This is very interesting. Have you repeatedly tested to ensure you’re not misattributing your symptoms?

I have been getting very odd symptoms since I caught a virus earlier in the year. I have had intermittent stomach pain since March. I have also had, in addition to the sore eyes and headaches - migraines with aura, nausea, dizziness, vasovagal syncope, and scariest of all depersonalisation/derealisation. I have been using many different screens this year as well as taking different supplements and changing my diet to try and get through all this but I still have no idea what is triggering everything.
I’ve seen multiple doctors and they can’t find anything wrong. My bloods are fine, my organs are healthy and my inflammation markers are as low as possible.

I’m basically using just an iPhone 15 at the moment which bizarrely is really comfortable to look at. I’m not ruling out getting rid of it for a Hibreak Pro if the symptoms persist. I desperately need a laptop or failing that a desktop and tablet but I have no idea what to get. I have been buying and testing gear but haven’t really got the answers I need to know how to proceed.

I had in the middle of May fever, headache and flu symptoms after testing the Arc A770.
Obviously I think it was related to a climate change rapidly that induced these symptoms.
I recovered in 3/4 days but during next days, I swapped my diet, It was low carb before than, higher in carbs and lower in fats.
I developed stomach ache, reflux, but these symptoms happening now in the late evening and morning. In some days I spend my evening with hardware testing cards and gaming sessions.
I related these symptoms to new GPU test
Now I'm fine during the day, I have some burping but I consume healthy organic foods, kefir, aloe Vera, probiotics, drinking a lot fluids.
I walk a lot and I practice bodybuilding to maintain my muscles.
I take Apple cider vinegar in the morning because I suppose my stomach acid is low.

Hoping to recover fast and find the right hardware in this modern chaotic life.

A lot of people who catch covid get new symptoms of something 6-8 weeks later. It is a possibility here.

And here you are saying you had a fever, headache and flu symptoms. Come on man, it's not climate change.

I also have the stomach issues that started in December suddenly. My liver enzymes were high in April, caught covid, tested again about 6 weeks later with another enzyme added.. the first ones went back to normal but this new one was high.. testing again in a couple weeks.

I think your symptoms might match my general post-Covid struggles.

I never had a stomach issues (mostly an immediate burping reflex with certain bad displays) related to screens before last year.

Right now, my main struggle with IPS/VA and other LCD panels is the stomach discomfort which varies between monitor/panel/phone.

I think it might be related to some neurological damage to "vagus nerve" and how our brain reacts to the triggers like light waves/emissions.

Also for some reason I seem to have almost no problems regarding the stomach state with OLED screens (besides the headache from PWM or dithering). Yet I still need to confirm this theory with more displays/phones.

I haven't seen a doctor about my symptoms yet, but I'm planning to schedule appointments for multiple of them.

Thanks for sharing. Can I ask what specific stomach issues you have been experiencing?
This is interesting territory as many people on this forum experience more than the typical sore eyes and headaches when it comes to flickering light.

languidicity So the main symptom is burping right after looking at the specific screen.
I can easily be free from "burping" if I do not look at those screens. Like when I am away of any PC/laptop screens I am feeling great and do not experience any stomach issues. I only need to look once at the problematic device and the "burping" begins…

Even If I make the display background completely black - nothing changes. Also some displays trigger some sort of muscle spasm feeling around the stomach area.

Some devices like iPhone XR even make me want to vomit. It stills triggers same burping, but with an extreme degree of observed symptom which leads to extreme nausea.

I've tried my old TVs with YAG-phosphor backlight and they are also triggering the symptoms.

All of that was not a case for me a year ago (before COVID hit me). Devices that were great for me are no longer tolerable.

Right now my desk monitors are Dell S2725DS and Dell P2225H which both trigger a slight burping, yet it's tolerable and I perform my work while not being bothered too much.

The safest device is Lenovo Y700 Gen 3. It's CSOT PLS panel. Not sure why, but I do not experience any issues with that. Also other OLED phones do not hurt my stomach, yet an OLED 13.3" portable monitor (some Samsung panel) does.

My symptoms are more consistent when I use computer. In other scenarios symptoms are less, so there's something in modern hardware/drivers combinations that triggers something in our brain.

pl01 OLED 13.3" portable monitor

What resolution? I've found that "2.8K AMOLED" panels by Samsung such as this one i've tested on recent laptops are actually, surprisingly, somewhat usable to me (not amazing, but still WAYYY more readable IMO than modern IPS laptops) and these AMOLEDs don't have much color fringing.

These 2.8K AMOLEDs can even become quite usable with Microsoft Basic Display Driver on Windows 11 (using the Intel driver makes them worse though) —— AMOLED interestingly seems to not be affected by the Windows DWM "rendering issues" that are known to affect LCDs, and is more primarily affected by driver issues and, of course, PWM.

However, all "1080p" or "1920x1200" AMOLED laptops I've seen are super strainy to me in general, at the panel level, and have a TON of purple and green color fringing. None of those are usable for me.

Now I'm fine.
A low carb is what's good for my stomach and gut.

1660 super is very good and I'm fine now with this.
I tried an Asus Rog Strix laptop 17.3" with an lg panel and a 1660ti on board.
Great experience
