Do blue light filtering apps work while watching normal TV?

by [deleted]

Hi.

I'm looking to buy my first smart tv, most probably with android as i'm already familiar with it on my phone and if the tv doesn't come with a night light/blue light feature already built-in i know i can choose from a variety of apps on playstore to get me covered.

The thing is that I'm not sure if the apps work while watching TV channels, like are "normal TV" and Android two separate entities with no link between each other and when you switch to TV the OS shuts down, or is the TV sort of managed by/part of the OS and all apps work in the background regardless?

Because I obviously want my app to keep filtering anything I watch, not just youtube and netflix.

​

Thanks.

Android tv and Android for phone aren't the same thing I don't think your gonna get any blue light filter on a tv sorry

Try getting blue light filtering glasses then.

Unfortunately, unless you get your "normal TV" through an android app (Sling TV, Hulu TV with Live TV, or Youtube TV in the US at least...), it is unlikely to work. Most smart TV's kinda step out of the way whenever you switch to another input. So if you have a cable tv box hooked up to an HDMI port on the back, once you switch to HDMI, android kinda goes away as would any blue light filtering being done.

That being stated, I did google "night shift smart tv" and found this post from a few years back...

It sounds like LG *MIGHT have some sort of "Eye Comfort" mode but they use their own operating system which I don't believe is android based called web os. The only reason it sounds promising to me is based off the fact it's built into the tv at the picture level settings , so if any TV would do what you're asking of it, it might be that.

But then you have to deal with web OS and won't have access to android apps... also I do not know if this is a standard feature or only certain models have it so you'll need to look into it further.

Apps like Twilight "look" warm and more yellow to me so if I were to translate that to a tv I'd look into movie or cinema presets. If you're doing it manually, you could try to achieve something similar by using the warm color presets, with lower backlight and maybe lower gamma settings.

I'm not too sure though as I am not as affected by blue light so I am only going by "look".
