Input Lag of 2014 TVs

Updated May 02, 2014 By Cedric Demers

The input lag of a television is the time from a picture is generated by the source to the picture appearing on the screen. An input lag of more than 50ms starts to be noticeable by competitive gamers, > 75ms by good gamers of fast games and > 100ms by the majority of people. Anything more than 125ms is not playable for a fast game.

Do not confuse the input lag time with the response time. The response time is the time a pixel shift from one color to another, which is significantly less than the input lag time.

How do I fix the input lag problem of my television?

Don't worry, most televisions can be adjusted to not have a high input lag. Try the following (which is how we setup the TVs in our tests):

  • Set the TV into the Game Mode or PC Mode
  • Disable all the settings of the television

Additionally, you can try a lot of combinations of settings/mode/inputs.

To get the lowest input lag on Samsung TVs, you need to turn on Game mode. You can find it under System -> General. This usually drops the input lag by half.

Why is the input lag important?

The input lag is only important if you are playing video games. Movies or TV shows are not affected because there is no interaction with the signal that you can do. If your television has a high input lag, you will see all your movements and interactions delayed on the screen. This is even more important in timing critical games like FPS or rhythms based (like Guitar Hero). When watching a movie however, even if the video is delayed by 1 minute, you will not see a difference unless the sound is not also delayed.

Why does the television take time to display a picture?

Input lag television workflow
The total input lag time is the addition of 3 parts

There are 3 main parts that delays the television: acquiring the source image, processing the image and displaying it.

Acquisition of the image

The source signal does not always come in a native format for the television. A digital television will have to convert the analog RGB component signal to digital. This conversion takes time. If you are seeing a lot of lag from an analog signal, try using a digital signal instead because the television will need to do fewer operations to transform it. The closer you are to the television native format, the less input lag you will have.

Video Processing

Once the image is in a format understandable by the video processor, it can change it. This includes:

  • Adding overlays (like menus)
  • Adjusting the colors and brightness
  • Interpolating the picture to match the television refresh rate
  • Scaling it (720p -> 1080p)

The time of this step is affected by the speed of the video processor and the amount of processing needed. Even if you cannot control the speed of the processor, you can control which operations it needs to do with the settings of the television. The more settings you enable, the more work the processor needs to achieve.

Some televisions have a dual core processor in them. This can help reducing the input lag if a lot of processing options are turned on.

Displaying the image

Once the television has processed the image, it is ready to be displayed on the screen. This is the step where the video processor sends the image to the screen. However, the screen cannot change its state instantly, the time will depend on the technology and components of the television. A plasma screen can change its picture faster than an LCD screen. You cannot control the time of that phase, it is fixed per television.

How is it measured?

How to measure a television input lag
An input lag of 40ms can be seen on the television.

The input lag is not in an official television specification because it depends on two varying factors: the type of source and the settings of the television. The easiest way you can measure it is by connecting a computer to the TV and displaying on both screens the same timer. You can find such timer here. Then, if you take a picture of both screens, the difference of times will be your input lag. This is however an approximation because your computer does not necessary output both signals at the same time. For example, the setup to the right indicates an input lag of 40ms (1:06:260 – 1:06:220).

In our tests, we measure it using a dedicated device made just for this, the Leo Bodnar tool. This is a lot more accurate than the two screens method (except for plasma TVs).

Gaming mode

Televisions makers knows that adding a lot of video processing increase the input lag which is why they usually have a gaming mode setting. The gaming mode will disable some of the most time consuming processing of the television. However, the gaming mode is not necessary the setting that guarantees the lowest input lag of the television; you will sometime need to play with the other settings to get an optimal input lag time.

I love Panasonic ST60. There's some many pros to this tv but I read a lot of lag issues reviews, not to buy this tv if you are a gamer. Should I buy or what do you recommend? Max budget is ST60 range and I'm buying this tv to play ps4.
We tested 54.2ms on it, which is average. It is definitely playable. Most people cannot notice an input lag of under 75ms, so I wouldn't worry about it.

I have a tv with 38ms lag time, I do competitive gaming will this be ok or even good for that?
38ms is pretty good. I wouldn't worry about it. Your internet probably has more latency than this.

Why do old CRTs do not have any input lag?
They do have an input lag, but it is a lot less than today's televisions. They are analog televisions: the picture information is not a series of 1s and 0s, but is a continuous signal. They don't have a video processor at all; the only processing that they do are very basics and analogic only. The signal can go straight from the input to the cathode tube without waiting to be digitalized or processed. They are a lot faster to display an image.

What is "CE Dimming"? Is it a Samsung-only issue? Is there a way to turn it off?
CE Dimming is the name of the technology of Samsung that dims the whole backlight of the screen on darker scene. There is no way to turn it off directly, even in the service menu.

The input lag that you specify for each tv model is a measure of the lag in "Game Mode" or at the normal settings?
The input lag measured in our tests is the lowest we could get with the TV. We test a few modes and different settings combinations. Most of the time, this correspond to the Game Mode.

Could you do a video with 2 TVs side by side, one with bad input lag and the other with excellent input lag, load up a first person shooter then just look from left to right and make the video slow motion? That would be very informative for people to really see what input lag can do in a video game that needs quick reflexes.
We could, but I don't think it would be very useful. The difference between a high input lag TV and a low one is about 30 ms, which also correspond to 1 frame of a 30fps game. Filming it in slow motion will just show one TV delayed by 1 frame, but it won't give you an idea of the feel. We thought about adding instead a tool to our website that adds a variable delay to a moving object, so you could experience it. The problem with this though is your computer screen also has an input lag, so it will be added to it.

I am planning on getting the BenQ XL2420G, it has G-Sync, does it have less input lag than the BenQ XL2420Z? I am looking for the best gaming monitor as I am a competitive gamer.
Unfortunately, we do not test PC monitors yet.

I'm looking at a 55" TV for gaming, low input lag is a focus for me. I also want to watch some movies and TV shows on it. Right now I'm looking at the LG LB6300, Sony W800B, and Samsung H6350. The Sony doesn't interest me due to their mode that lowers motion blur. I don't want to have a dimmer tv with noticeable flicker. Which one do you feel would be best for gaming if you ignore Sony's Impulse mode? The other issue is the LG 6300 is $899, I've also seen it at $799 sometimes on Amazon. The other two are around $1100. Is it really worth the extra money for the Samsung or Sony? Right now the LG looks like the best choice, the only issue I see is the medium motion blur. I really appreciate your feedback, thanks!
Yes, the upgrade from the LG to Sony/Samsung is worth it. Far better contrast ratio and uniformity. If you don't plan on using Sony's Impulse mode, it is a tougher call compared to the Samsung H6350. Picture quality wise, they are very similar, so you won't be wrong either way. The difference in term of input lag isn't very noticeable, so go for the Samsung H6350 (it has better extra features).

So all these TV's are horrible compared to 5ms tv/monitors I see all around the internet? Or is the 5ms a lie?
The 5 ms that you are referring to is not the input lag, it is the response time. They are unrelated. The input lag (15-50 ms range) is the time between the input and the display. The response time (4ms-12ms range) is the time a pixel takes to switch to another color (usually measured from gray to gray).

Is there any chance you can test the input lag on the Samsung f8500 plasma with the hdmi input named Game(instead of PC) and the tv in game mode? I have this tv and with the hdmi input relabeled to PC the picture quality suffers too much. I have heard that recently Samsung sent out a fix and the lowest input lag is with hdmi named Game and Game Mode on.
Unfortunately, we do not have that TV with us anymore, so we cannot retest it.

I have a Sharp Aquos LC-90LE857U television. I also have a Bose Lifestyle 535/525 series 2 home entertainment system hooked up. Everything seems to function fine except in regards to my PS4 and Xbox One consoles. Both seem to have a lag in between the controllers and the image displayed on the tv screen. I have changed the settings on both consoles but that doesn't seem to help. Both consoles are run to the Bose first, then the Bose is connected to the tv via 1 HDMI cable. Any advice?
Have you disabled the processing options of your TV / put it in game mode? If so, it might be the Bose that adds the input lag (although unlikely). To try for it, connect your consoles directly to your TV instead. If it does resolve the problem, you still can get the audio via your Bose by HDMI Arc or the optical connection.

I got 3 questions. 1) Are you using the leo bodnar lag tester for your input lag tests? 2) Also, is it true that a plasma TV reports a higher input lag number because of its luminescence? 3) If so, should we expect a little better "feeling/experience" from a given plasma input lag number?
1) For 2014, yes but for 2013 we used the two screens method. 2) Yes it is true that the tool isn't accurate for plasma. The flickering of plasma TVs messes up with the tool because the tool is using a luminosity threshold to detect the lag, so it takes a little longer for the plasma to trigger it. 3) Indeed, maybe like 10ms less.

Is there a work around for game mode? If I disable all bells and whistles but leave on Movie mode to avoid CE Dimming, will I achieve a work around?
You won't get a low input lag just by disabling everything. CE Dimming can be avoided by going into PC mode also.

Is G-Sync worth it? Or is it a marketing plan?
It depends on your setup. If your computer has no problem rendering a game (it generates each frame in time for the monitor), there is no visual difference. In the complete opposite, where it is just too slow, it won't help because there will still be shutters. It is really just worth it in between those scenarios, where the computer is fast enough for most frames, but some frames lag behind.

Do you know the input lag of the Sony kdl60w630b?
No, we didn't test that TV. Based on the similar Sony W* that we tested, it is probably below 30ms.
