Hi Michael! So where to begin explaining this and keeping it short! When you see these seemingly conflicting specifications for the LG - 42" Class (41-9/10" Diag.) - LED - 1080p - 120Hz - Smart - HDTV, Model # 42LB5800, it can be frustrating, but let's take a step back and look at this from a different perspective. Source footage has never been more than 60Hz and one thing that you need to understand is that you cannot add more detail beyond what's in the source footage! Blu-Ray movies play at 1080p/60Hz. Remember the 1080p versus 1080i comparisons? Video is displayed at either 60 interlaced frames/second or 30 progressive/second at 1920 X 1080 resolution. The original footage for movies recorded on Film is actually 24 frames/second but is up-converted to 30 frames/second with a process known as 2:3 pull down! Why is this done? Because 24 does not divide into 60 evenly, so the 2:3 pull down distributes these frames across 30 frames by interlacing them, combining and shuffling, to fit them into 60 frames/second to match the 60 frames per second ( measured as Hertz-Hz) of your TV. There isn't any commercial media that exceeds the 1080p/60Hz refresh rate yet(4K may change all that when it is fully implemented, but that's a different story for a different day!) Interlacing and 2:3 frame pull down is merely converting the video so it can function on your TV, it does not add anything to the video! So what does all this have to do with higher refresh rates and what this TV's true refresh rate is? When you see a TV with higher refresh rates of 120Hz or 240Hz, the TV is resorting to "tricks" to achieve this through a process known as interpolation! This process injects new frames into the 60 frames that you TV is displaying that were not on the Blu-Ray disc or the television signal you're watching! These new frames are made by combining and processing the data of the frames surrounding them, generating the images your HDTV thinks it should draw between the images it's told to draw by the media. These refresh rates and motion-enhancing modes higher than 60Hz can produce a surreal effect when watching movies and television shows. For sports and video games, those added frames can help reduce stuttering and blur, and the action will be easier to track, but you should know when to turn these enhanced refresh rates off, and watch with the "default" 60Hz or 24Hz film mode. As a general rule, if you're watching sports, or playing games on your TV, use the higher 102Hz refresh rate, but if you're watching a movie or content that involves people speaking, turn it off. You've probably heard of the "soap opera effect"? That is when you're watching at the higher refresh rate and people look like creepy dolls. The 42LB5800 HDTV should be listed as a 1080p/60Hz TV but it is capable of doing 120Hz. It might be that people are mistakenly listing the MCI 120 as being the 120Hz refresh rate, but MCI is something totally different and that would take up a whole new discussion and explanation, so hopefully this is of some help. A 120Hz refresh rate can be beneficial for certain situations, but a higher refresh rate should not be considered a good reasons to spend more on an HDTV. A 60Hz refresh rate is sufficient for watching television and movies!...IFV
Sorry, there was a problem. Please try again later.It is a 60Hz device. The description provided by Best Buy misrepresents the device in a few places and correctly identifies it in others, and I have submitted a review for them to change their posting. I have also confronted them about this issue a week ago in Pensacola, FL. This confrontation did not apparently mean anything to them, because the posting has not been changed. The MCI (Motion Clarity Rating) provided by LG is 120 which corresponds to a 60Hz refresh rating. A 600 MCI rating is a 120Hz refresh rate. If you are looking for the 120Hz device with the exact same specifications and size, you will need the 42LB6300 model which is over $100.00 more.
