Hi, I just bought a Hisense 50K23DG, in part because the box read "True 120 hz refresh rate".... but after goofing with the picture settings and reading the manual, I am beginning to think it's not an actual refresh rate, but just an effect. When I switched the tv on tonight (input set to bluray player if that makes a dif) and on the screen flashed something about 60Hz. So I started poking around and noticed the manual states, "120Hz Effect: Inserts frames to reduce judder in fast action scenes. You can select Off, Low and High. Only available in the models that support 120Hz." Now, if it were actually 120Hz refresh rate, wouldn't it actually be refreshing and not simply inserting additional frames? 

 

I already know Hisense is not a great brand, and I've read plenty of posts by others who think they're garbage, so please save me those replies. I am looking for a real answer here. Would love to know if someone knows for sure about this model and/or what wording to look for when it comes to 120Hz refresh rate tvs. I've already returned one tv after falling for the high refresh rate gimmick and I will return this one too if it is not really a 120Hz. I would rather save up another couple hundred bucks and get one later - when football season rolls around I imagine a fake refresh rate will drive me nuts.

I don't know anything about this model specifically, but there are no video sources (other than a computer video card output) that actually have 120Hz native source refresh rate. Not broadcast ATSC HDTV, blue-ray, game console, etc. None of these actually supply signals that are natively 120Hz.


So the TV's that advertise 120Hz all have modes to interpolate frames to "smooth out" the motion, although in general, these just make the signal look like crappy soap operas so most people that care about video quality turn these modes off.


The only way for you to test if the TV can actually support 120Hz is to connect a computer and turn up the refresh rate in the video card settings.
