Reddit mentions of Luminoodle USB Bias Lighting - LED TV Backlight Strip - Ambient Home Theater Light, TV Accent Lighting to Reduce Eye Strain, Improve Contrast - White - Large (30" - 40" TV)

TV backlights are amazing, if you play a lot at night.

Static color. I'd hate if they were responsive. I have these for both my monitor and my TV. They help with eye strain A LOT and I honestly think it helps with the contrast of colors.

I've been battling with this myself during this past year. This is what I've learned.

Here are the factors that influence eye strain:

1. PWM Cheaper and older LED monitors use a technique called pulse width modulation to lower the brightness of the screen. So instead of lowering the power of the LED, the LEDs are still at max brightness but flash intermittently on and off at a slower speed. This produces eye strain on a lot of people and the Dell U2412M (I also have one in a box) has PWM.
   
   A simple way of checking if your monitor has PWM is lowering the brightness and waving your hand fast in front of the monitor. You should see "steps" instead of a fluid motion. Another way is by using a camera.

2. Text size Sadly in macOS you can't scale all the UI (either hiDPI or not) but in Windows 10 you can scale. Text should be comfortable to read. Small text produces eye strain, specially if you need glasses.
   
   For example a 1440p monitor at 24 or even 27 inches may produce text that is too small to read if you are over 35 years old. In my experience the ideal resolution is 4K at 27 inches with hiDPI on macOS or 175%-200% scaling in Windows.
   
   
3. Blue light Some monitors and some software such as F.Lux allow you to lower the amount of blue light which for some people can cause eye strain.
   
   
4. Room lighting This may seem trivial but is very important. You need to have some light source behind your monitor. This is called bias lighting and you can buy some LED strips to fix this. Also beware of strong light sources coming from your side vision such as windows.
   
   
5. Matte panels Some people have problems focusing on some matte anti glare coatings which forces your eyes and produces eye strain. It's rare, but I have suffered this myself with some Dell monitors. The problem is that it's very difficult to buy a glossy monitor these days.

Added it myself, works on any 5V USB port your TV should have. Here is the product. There are probably cheaper versions of it available, but this one was recommended by a colleague.

This Loominoodle light strip. I like that its USB powered, so I just plug it into my TV's USB port and it goes on and off with the TV. My only wish is that there were controls to adjust the brightness

I have this TV and I have the [Luminoodle] (https://www.amazon.com/gp/product/B01LR3RAVU/ref=oh_aui_detailpage_o04_s02?ie=UTF8&psc=1) and it works fine. The only thing is that the USB will stay powered for 15 minutes after you turn off the TV. Get the Large if you want it to all the way around the back of the TV. I get a lot of compliments on the way it looks and think it makes the TV picture look sharper and darker. The TCL has a horrible backlight and this fixes that somewhat.

It's called the luminoodle

Try getting a bias lighting kit. It helps a lot in general, and they are cheap on Amazon.

Example (I do not necessarily recommend this model)

I've been using [this] (https://www.amazon.com/gp/product/B01LR3RAVU/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1) for the past few weeks and really happy with it.

With shipping and tax and everything it comes out to $50 which is much more reasonable, but I'm wondering how large of a difference there would be compared to this strip that I've heard general good things about (but not nessicsary in a professional setting)
