Technical question: Samsung 6 Series TV: DC or PWM dimming?

by Mar 8, 2018 4:00AM PST

Hello all,

I have tried searching far and wide but I cannot get an answer to a simple question: Does the Samsung 6 Series TV use DC or PWM dimming? The specifications state that it is an LED LCD TV that uses Micro Dimming: https://www.cnet.com/products/samsung-un55k6250af-6-series-55-class-54-6-viewable-led-tv/specs/

I am asking because I suffer from extreme eye strain from most monitors, but not from this TV, and I would like to identify what is different about it (e.g. if it relates to screen flicker).

Thank you very much!

PWM is all I ever see.

But the PWM rate is usually in the 10 KHz and up so the strain is usually from the 60Hz or less rates.

Maybe you should check with your doctor or try models without any dimming feature?

PWM assumed, but no documentation found

Thanks for your reply. I assumed it was PWM for this model, but I have never been able to find documentation that confirmed it. Can you remember where you found this information?

I have been to two separate eye doctors. Their knowledge on the topic is limited and they don't seem interested or able to test if it's due to certain wavelengths, flickering or anything else, thus I feel left in the dark. It will be worth testing a model with DC dimming, though, just to rule this out.
