The feedback loop between your game controller, your brain, your fingers and the action on the TV screen is a delicate cycle. Any delay can diminish the thrilling immediacy of the playing experience. Or, in some games, get your character killed because the game doesn't respond to your reactions quickly enough.
With online games at least, the biggest source of those delays is latency between your console and servers on the internet, which is largely out of your control. But another source of lag, for all types of games, is introduced by the TV itself.
It takes mere milliseconds for a video signal to travel from your console through the HDMI input on your TV to appear on the screen, but too many milliseconds can be noticeable to your brain, or downright deadly to your in-game character. Those milliseconds are known as .
Happily, most TVs have a picture mode specifically designed to minimize input latency, generally called game mode. One of the tests I perform for every TV I review for CNET measures that lag time. I also like to consider gaming experience, viewing angles, picture quality, screen size, contrast, brightness, color gamut, frame rate, smart features, refresh rate and support for high dynamic range content.
Here are the 2018 and 2019 TVs I've tested so far, ranked for input lag. Lower numbers are better.

What else you need to know about input lag
How to turn it on. In most cases, viewing in game mode isn't automatic so you'll have to turn it on manually, and sometimes the setting can be difficult to find. Many use a picture mode called "Game" while some, like Samsung and Vizio, let you apply game mode to any setting (Samsung buries it deep in the menus, as seen below, while Vizio calls it "Gaming Low Latency"). Check individual reviews for details.
Game mode makes a difference, except when it doesn't. As you can see, many TVs cut lag substantially when you turn on game mode, but plenty don't. In general, expensive TVs with elaborate video processing get more of a benefit when you engage game mode.
Most TVs' game modes are good enough for most gamers. No matter how twitchy you are, it's going to bebetween 15 and 30 milliseconds of input lag. Many gamers won't even be able to discern between game mode on and off -- it all depends on the game and your sensitivity to lag.
Turning game mode on can hurt image quality (a little). TV makers' menus often refer to reduced picture quality. Reduced picture quality is generally the result of turning off that video processing. In my experience, however, the differences in image quality are really subtle, and worth the trade-off if you want to minimize lag for a great gaming experience.
4K HDR gaming lag is different from 1080p. The display resolution you game at has an impact, and since consoles such as the and Xbox One X prominently feature output for games, I started testing for 4K HDR lag in 2018. In general, the numbers are similar to the lag with standard 1080p resolution, but as you can see from the chart above, there are exceptions.
Vizio's Input 5 is weird. The fifth HDMI cable port on the Vizio P-Series and PQ TVs (both
Testing is an inexact science. I use a Leo Bodnar lag tester.. You might see different lag test results from different review outlets, which may use Bodnar or another method.

What's the best TV for gaming, period?
, the best TV for gaming is one that has the best picture quality for viewing everything else, too. Games benefit from deep black levels, bright highlights and uniform screens just as much as movies and TV shows do.
Yes, there are other factors, but they don't apply to most gamers. If you play the same game constantly on your smart LED TV and never put anything else on the screen, and that game as a bright static element that stays in the same place on the screen (like a HUD or other status display), you might be at risk for. But most gamers don't have to worry about OLED burn-in.
If the TV input where your console is connected is shared with other devices and you don't want to remember to re-engage game mode all the time, an auto game-mode feature might be useful. And some cutting-edge PC and Xbox One X gamers might appreciate variable refresh rate. Auto game mode and variable refresh rate are found on Samsung's 2018 TVs, and many appear on other with , including sets from , and .
Most gamers, however, will find that the best TV for gaming is the best high-end TV, period.
I'll continue to test 2019 TVs for input lag as I review them.
