in tvs do more than 60 hz have impact

[Rennas9723]

i see tvs with 1000 pmi in LG TV's wich if im not wrong is the same as hz but i theres something saying cuz of the hmdi cable or something it only supports 60hz so i got confuse do 1000 pmi (hz) have impact over an 60 hz tv or 100 pmi ?

no that index rating means nothing mate,60 htz is 60 htz & anyting over 60fps is wasted.
its just digital processing the majority of the time & for gaming while it may smooth the image it increases lagtime & image latency.
there are a few very 4k oled screens that are actually capable of native 120htz input & display but they are insanely expensive.

It really Really depends. Some manufacturers are cabaple of 120Hz 1000PMI native refresh rate of the panel, but still only a very very few actually accept a 120hz 100pmi source and display it as is without what is called interpolation of some sort. Most manufacturers that claim multiples of these values (multiples of 60hz or 50pmi) are multiplying or interpolating the video signal which provides a better (subjective) optical motion. Some of their solutions cause serious input lag due to the amount of processing required to make more frames out of just 60fps (60hz). Displaylag.com: http://www.displaylag.com/ is a site that catalogs the input latency and "real" display frequencies of a huge number of TVs. When you find a good few you like that are on the market, check their ratings on sites like that.

CNET also has a great article on it (http://www.cnet.com/news/ultra-hd-4k-tv-refresh-rates/), albeit pretty lengthy, but only because its a bit of a convoluted subject (and thus the reason for consumers getting a tad confused and mislead by the manufacturers).
