What's the refresh rate?

I believe 60 Hz. I play Titanfall and Black Ops 2 at MAX settings without ever tearing. Not sure if that is because the monitor is good or my computer uses two 670 gtx cards with overclocked CPU. Whatever the reason, I've never felt the screen was slow. :)

Refresh rate is 60hz if that's what you are really wondering? Frame rate is determined by the original recording and the video card. As an Ultra High Def, images don't appear "jittery" or pixelized if this is the concern. Long and short, garbage in = garbage out.The biggest downfall of this stunning monitor is the obscene A/R coating with its overwhelming sand sized rocks on the A/R film. They should have sent their visual engineer to Zeiss for training before letting him out of his cubical to wreck havoc.

its already in 144hz, for games, you need to change in video settings. i only changed the contrast, colours etc.

You have to force it in your video card drivers. However, I wouldn't bank on hitting 120Hz. 90Hz might be a more realistic goal.

Refresh rate isn't as important as it was a few years back. Look at the motion rate, This set has a CMR of 1440, that is the highest CMR of any set to date.

Double check your settings on the monitor. Mine didn't come with DisplayPort 1.2 enabled by default. You may be getting a 30 Hz refresh rate. Similarly, if you're using HDMI and not DisplayPort, you'll be stuck on 30 Hz not 60 Hz. I just turned mine way down and didn't notice any flicker.

120Hz, based on the independent assessment here: http://www.rtings.com/info/fake-refresh-rates-samsung-clear-motion-rate-vs-sony-motionflow-vs-lg-trumotion

Yes, it's limited to the usual 60Hz. With modern monitors that's just fine. Modern LCD screens do not have the laser sweep of old CRT screens, so you won't need to change your refresh rate to desynchronize from your overhead lights anymore. (And if you're going significantly over that in games, you're just wasting power, so vsync would make more sense in anything that exceeds this rate.)

make sure you set the refresh rate to 144 through whatever control panel you have for graphics (Nvidia or AMD) If you don't have drivers, then get them

The refresh rate is actually (probably, hard to get a definitive answer) 120hz; Samsung uses a technology they call "clear motion" to provide what they consider the equivalent of a 240hz refresh rate. Some other manufacturers do likewise (using either the same or different technology) to claim a larger refresh rate; for example LG calls theirs "TruMotion". The technology is beyond me, but if you'd like more details do a search for "refresh rate", or ask (in a search engine) a question like "what is Clear Motion refresh rate". I know CNET.com does a fairly detailed explanation. Both they and Consumer Reports cautions on taking these claims at face value as in their reviews they say they commonly see some tv's w/lower claimed refresh rates having a better pic (less fast action blur) than other tv's w/higher claimed refresh rates. It sucks, but we're stuck with this goofy arrangement and at the mercy of the manufacturers claims.

It better have the 240HZ refresh rate! That is my understanding. When this question was posted I looked at the specs from other sights including cnet which confirmed that it was 240HZ. This is supposed to be Samsung's top of the line model.

Refresh rate. You don't need high refresh rates for the PS4 so you can go with the 2455.

I have the 70 inch model. I'm not sure about the refresh rate, but the motion of the on screen images is very fluid; more so than smaller TVs I've had. I think that is the LG Trumotion effect. Here's a link that explains it a little more: https://answers.yahoo.com/question/index?qid=20130307210110AAVgVXD

That depends... If you are playing something at 1080p 30hz the U-Vision adapter will upscale it to 2160p (4k) 30hz. If you are playing something that is over 30hz you will get an output of 1080p at the same refresh rate as whatever you are playing whether it's 60hz or 120hz. But the converter will give you expanded color depth and some better details. I'm assuming you are using hz and fps interchangeably for the answer above. If not, see below... The screen of the TV itself will always refresh at 120hz no matter the input, what you are limited by is the image processor and hdmi cables bandwidth. If you are displaying something that is 30 frames per second on a TV that refreshes at 120hz each frame of video will be displayed for 4 of the TV frames. If you are watching something that is 60 fps it will show up for 2 of the TV frames. The only way to send a true 120fps signal to a TV is to do so from a computer as far as I know. Tvs that have motion smoothing will interpolate (make up) a frame that is partway between the actual frames that the video source is putting out so that the motion appears smoother. This TV (depending on what firmware you have) does do this. The only downside is that you ha e to access the manufacturer service menu to enable or disable it.

The Samsung that I purchased has the 120HZ refresh rate. I can take a picture of the box that it was shipped in if you like.

On my box it says 2ms, but man, this is more than enough in Titanfall battles @ 144Hz

According to LG's own website, the refresh rate is listed as 120hz. Whether or not it is, I don't know. There are no TruMotion settings in the menu of the 42LN5400.
