LG Finally Promises to Fix its OLED and LCD 4K TV HDR Gaming Input Lag Problem

by on November 28, 2016

Stephan Jukic – November 28, 2016

As we and a number of other tech watchers had initially reported, LG’s 4K OLED and LCD TVs ended up suffering from a major flaw when it came to using them for 4K UHD console gaming with HDR enabled. Specifically, the company’s 2015 and 2016 4K HDR TV models couldn’t manage to deliver HDR with the low input lag they are generally capable of delivering in their Game Mode settings. Instead, gamers who wanted to enjoy the rich visual impact of high dynamic range while playing console games from the Xbox One S or the PlayStation 4 Pro were (and so far still remain) stuck with much slower, input lags of 50, 60 or even more milliseconds. For competitive gamers in particular, this is something of a minor disaster.

Input lag is the time delay between when a TV receives instructions to change image data on its display and when it actually does this. Thus if you’re using a controller, the input lag is what dictates how quickly elements on a TV’s display change according to what you’re trying to do. In LG’s OLED and LCD TVs and especially in their 4K models with both display types, the input lag seriously bogs down if high dynamic range is enabled for gaming, to the point where gamers have set up not just one but two petitions to LG so far at the website

At first LG was rather evasive on this whole issue but now it seems that the gaming community’s complaints have been taken seriously and the company has confirmed that it will be rolling out a firmware update which is going to address the HDR lag problem in its select TV models.

According to a response submitted to Forbes display technology reporter John Archer, LG states that:

“LG Electronics has been made aware that some customers are experiencing lag on their displays when playing HDR games on LG TVs.

LG engineers are currently working on a firmware patch to address the issue which is expected to roll out shortly.

LG is also working on a solution for 2017 LG TV models which may include the option of an HDR gaming mode.

LG is committed to providing the highest standards of product quality and customer service.

As such, we regret any inconvenience this has caused our customers and confirm our commitment to resolving this issue as quickly as possible.”

As Archer himself points out, LG’s response was nicely timed to coincide with the current Black Friday and Cyber Monday sales event which is going on for all major retailers of electronics across the U.S and serves to (possibly) reassure many would-be buyers of this brand’s otherwise usually excellent or in the case of their OLED 4K TVs, downright superb ultra HD display technologies.

The HDR gaming problem applies even to older LG TVs without HDR display according to some readers

However, it is worth pointing out that LG’s response to their input lag problem is distinctly lacking in details and fails to mention whether an HDR gaming mode will be introduced to their TVs or if the HDR lag will simply be reduced in a more general sense. Another crucial piece of missing information is also the timeline for this badly needed firmware update. Will it come before the end of 2016 or can we expect it in early 2017?

We ourselves are no strangers to LG’s responsiveness to any criticism of their 4K TVs that the company feels is unwarranted, and as an upcoming piece of reporting on other LG 4K TV issues we’ve noted will show, LG can often respond in considerable detail when confronted with specific complaints about their 4K UHD TVs. In this case however, we definitely look forward to a better answer from the company as far as the HDR gaming problem of their TVs goes.

Samsung, Sony and Vizio’s 4K HDR TVs for 2016 have generally shown themselves to be much more adept at handling 4K gaming from a console with HDR enabled. Samsung in particular showed itself to be nicely ahead of the curve by delivering superbly low input lag in its TVs’ gaming mode with HDR and 4K resolution both enabled. This is something we’ve noticed in all Samsung 4K HDR TVs we’ve reviewed for 2016, while noticing it in only some of Sony 4K HDR TVs.

    Hmm, I don’t blame a company for not doing my research ahead of time! If you don’t like the input lag, don’t buy the TV!

      Its an interesting comment for a premium Tv set. I would agree with you on some mid or low level set. I however disagree with you on a premium set. A premium set should be mean that the additional cost of ownership translates into not having any “real”: isssues. If I buy a lambo or ferrari and I complain about gas mileage then you have a point. If however I buy a Premium set that loses on performance then the consumer has a point.

        Thats a terrible comparison. Yes a Ferrari and a Lamborghini is expensive but they are not without issues. Ferrari and Lamborghini pushes the boundaries for performance but at an expense of reliability. I know because I own a Lamborghini Huracan. And unlike most owners I actually drive my exotic. My Lambo has “REAL” issues. I constantly having to take her in for problems a $200,000 car should not have.

        Case in point just because you pay high dollar for something does not mean you will be free of all problems that will come with it. Most Toyota’s that cost 100x less are more reliable.

      There were no numbers available on the models available in my country. You seem unaware that it’s a big world with lots of different models in each region. I bought a TV with all of the information available to me, and it wasn’t until I bought it that I discovered that it had 140ms input lag in HDR mode. Literally unplayable.
      And there was literally only a single website that holds complete input lag testing information for various TVs, and it’s far from an exhaustive list. You can’t blame consumers for not knowing everything.

      I hope this patch includes my LG 49uh651v, or I will be ditching it very soon.

        Hey there Mike, I can sympathize with your predicament and it’s something we’re working on, a sort of comparison chart of different model numbers for different parts of the world. In many cases, the same essential TV goes by a completely different name in another country and this can severly confuse consumers. On the other hand, as your example illustrates, the issue can be tricky since a 4K TV that seems to be the same as a certain U.S model can offer some major specs defect that was unforeseen. As for LG’s input lag problem, we’ll have to see how it pans out. We hope it works well because LG’s 4K TVs do offer otherwise solid display performance for gaming.

    I was about to buy an LG 55″ Oled on Amazon but having read this report I’m going to go for the Samsung instead. I play a lot of online games and couldn’t bear this kind of lag. Thanks so much for the article.

    definitely, stick to other brands, lg are also selling 4k tvs that are really 2.8k [bar oleds], so they are in fact rgbw instead of proper 10bit panels sadly.

    the fact they also messed up the fw update for game mode hdr is true also for all range of lg 4k tvs now, including oleds, which make the picture extremely dark, by trying to solve this they said to up the level of dynamic contrast and brightness, the result is very saturated colors light levels, not good, why can’t lg let consumers/gamers choose how they want [ability to roll back fw etc], sadly in this respect, lg are no longer good in this gaming area, u might have the input lag but not the picture quality to go with it, shame that….

    In LG the gamer faces the input lagging problem. So LG now fixed this problem for the hdr gaming. Now the gamer and the user of LG get the relief, now they can play without the lagging. For know which game they can play click here –>
