I am not very clear. Can you elaborate.
It varies from manufacturer to manufacturer.
Well after a certain number rating the end result is insignificant.
You have 100hz in samsung which was usefull in 2010 models which meant it had the frame insertion tech,while 100hz in 2011 samsung model meant it had backlight scanning,which from what i saw and others observation is that it doesn't do anything to beneficial to PQ other them making it more dim.
Only the 200hz samsung has the frame insertion such has in the series 6.
In 2010 and prior lg had already started advertising the trumotion 200hz which was inferior to the then 100hz models from sony/samsung .
lcd tvs with a advertized 200hz today atleast from samsung/sony are able to get the 1080lines of motion resolution,while the other models with 800hz and what not are insignificant with regard to 2d motion resolution.
So the use of the hz rating is inconsistent from manufacturer to manufacturer and from one tech to another.
