Nintendo Switch

MagnuM Well, after taking my Switch to a friends house (also an old LCD Samsung Series 6 but Plasma instead of LCD) and having the exact same issues occur, I was starting to doubt my Switch more and more. I hate doing this, as the store likely has to swallow the loss, but I asked the manager at Shopper Drug Mart if I could do an exchange, even though they mentioned that wasn't their typical policy and that they usually ask customers to go through the manufacturer (i.e. Nintendo). Doing so would mean not having my system during the holidays and my week off, but I guess my niceness paid off, as she made an exception for me and allowed me to have a system exchange performed.

I hooked up Switch #2 in the exact same way as Switch #1, and there are no more flickering lines anymore. Looks like I may have just had some bad luck and was handed a slightly defective system.

There's another more unfortunate possibility for Switch #1 that I'm hoping is a non-factor! I was setting it up in my basement that has a cushy high pile carpet that generates a heck of a lot of static electricity. Each time you shuffle around on it, either on your knees or your socks, you become ... ElectroMan (or Woman!). Every time I touched the Switch handheld while setting up the original system I would give it a shock that would always startle me like it does when you touch a lightswitch. I'm hoping these repeated shocks (it must have gotten at least 10) didn't do anything to the system. This was always against the handheld instead of the dock, but the areas I was shocking it at was always along the bottom edge near the charging port. Could the flickering lines of my first Switch have been caused by static damage perhaps?

I wouldn't discount it as a possibility.

MagnuM Is the Switch still good for you (in terms of eye comfort)?

ryans I've only been playing it docked with my old trusty 40" Samsung LCD from 2008. The initial setup is done on the handheld itself though, and I would have known whether I had trouble with it because I would have had aching eyes and felt seasick within seconds/minutes of looking at it like what normally happens with most LED computer monitors. Maybe the handheld screen is backlit by CCFL on the Switch handheld? I'm not sure, but let's just say it was a positive surprise (for once!)

On the Wikipedia article for the Nintendo Switch, it states this about this display:

Display
6.2-inch, 1280 × 720p LCD (237 ppi)
Up to 1080p via HDMI while docked

JTL Another interesting tidbit is that there is no polarization on the Switch screen. While wearing sunglasses, there is no darkening in any orientation. I remember someone here was once theorizing that polarization could even potentially play a factor.

Yeah, I would go as far as to say there is no chance it's CCFL backlit. Even the DS and PSP were LED backlit. Nobody touches CCFL for these things nowadays for many reasons especially on portable devices where it adds extra power draw and bulk.

Also before pressing post reply I looked up switches being taken apart and it's definitely LED.

Soreeyes That's very interesting then. I thought it was essentially all LED light sources I have a problem with, but maybe not! The list is short, but so far, I don't seem to have problems with the Nintendo Switch LED backlight or the overhead LED lights they installed at work to replace the old fluorescent tubes.

Now I'm wondering what I'm really being bothered by. I bought a flicker-free LED BenQ monitor back in 2013 thinking all my problems would be behind me, only to notice the same type of sharp eye/head pain, but that it just took a bit longer to be brought on.

Are there other types of flicker besides PWM that could be a factor? If there is, why are these other forms of flicker not as problematic on a CCFL-backlit monitor? I can also get similar sharp eye pain / head pain if I increase the brightness too high on my known-good Dell U2410, but it takes longer to set in than any LED-backlit monitor gives me.

DC ripple exists on probably all "flicker-free" monitors.
Pixel inversion is another type of flicker that all LCDs seem to have.
Tearing basically is a form of flicker, maybe harmless, but who knows.
Small power or status LEDs can flicker - don't underestimate this.

I recently found this old article which is pretty interesting: http://www.conradbiologic.com/articles/SubliminalFlickerI.html
Part II covers fluorescents.
It seems he is/was doing research on flicker.

KM "An extreme sensitivity to subliminal flicker is probably due to prior neurological damage."

This passage was most interesting to me. I know some people here have talked about having issues with head injuries before, and their issues started afterwards. Some symptoms of post-concussion syndrome also involve light sensitivity. I however have not had any history of head injuries.

But I'm starting to wonder about side effects of certain drugs (i.e. pharmaceuticals) like anti-depressants or even antibiotics (e.g. fluoroquinolones). God knows what some of these drugs might be doing to our brains...

I thought this too @ all LED = bad for me but it's not quite the case it's more 99% is bad

PSP, DS, and a single LED backlit 2015 Bravia TV are perfectly fine for me. I really wish I knew what made these fine and others not. I'd assume if I had the money and time I could find many more LED lit things that don't destroy my eyes and brain. I also find OLED to be perfectly fine as long as there's no visible to the eye PWM and it's running off something that doesn't cause me symptoms (like an OLED phone using lollipop is always fine for example as was the original PS Vita) never tried an OLED TV though and i hear they work differently. White backlight OLED + filters on top or is it only LG that does this? Regardless I plan on trying one when I can

LEDs and screens aren't created equally so it might be that the switch you have with the specific panel it has just happens to work perfectly for your eyes. It's a shame you can't see the make and model of the screen without taking it apart.

Soreeyes White backlight OLED + filters on top or is it only LG that does this?

Yes, the panels come from LG and other manufacturers buy and use them, too. True RGB OLEDs in TVs are very rare.

KM The company JOLED is supposed to be manufacturing RGB OLED monitors this year. 3 monitors are coming out and they are 10 bit. Maybe they will cause no pain.

So the latest switch software update now gives me eye strain. It was perfect before. I think they are changing things due to the new switch pro coming out. Apparently that will be 4k and use Nvidia upscaling AI technology. Kind of sucks. Anyone else having issues?

thorpee i got same condition. After update april or mei 2020, my switch give me eye strain. do you find any solution?

This all makes me concerned for the Steamdeck coming out soon. I have a preorder in…

ludwig The xbox and playstation use AMD GPUs as well though I believe. No issues there with their respective panels (UST Projector and an older 2k LG LCD TV)
