Can anyone explain to me why (at present day) the refresh rate of most LED LCD TVs is 60Hz? Is there a physical limitation to the technology of LED TVs that make it much more expensive to implement a faster refresh rate? Additionally, what is a "native" refresh rate, vs. a "simulated" refresh rate (eg. Vizio's Clear Action, Samsung's Clear Motion, Sony's Motion flow, etc...) in terms of the physical processes causing the real or simulated refresh rates? Is a simulated refresh rate even noticeable compared to a TVs native rate?
I used to own a Panasonic Plasma that was natively 600Hz. It was great for gaming and watching sports. Now that plasma's have unfortunately gone by the wayside and I have to get a new TV, I'm struggling to find reasonable deals on high native refresh rate LED TVs, which is why I was hoping to get a better intuition on what the real world differences are between native rates and simulated rates.
This webpage goes into a little detail on comparing native and simulated refresh rates for different brands, but ultimately falls short of describing the inherent differences of the native and simulate rates.
I want to emphasize that I am interested in better understanding the technology differences between LED TVs and Plasma TVs that result in limitations on their refresh rates, and understanding the technology that is supposedly simulating non-native refresh rates. Nonetheless, if this is still not the right community to be posting this question, please let me know and I will move it.
