Ever had that soul-crushing moment in a game? You’re lining up the perfect headshot in Call of Duty, you press the trigger, and… nothing. A split-second later, your character fires, but the moment is gone. You’re toast. That frustrating gap between your action and the on-screen reaction is the dreaded input lag. For years, gamers have wondered How To Fix Tv Input Lag, often blaming their controllers or consoles. But let’s be real: the biggest culprit is often the very screen you’re staring at. It’s a problem that can turn a high-octane experience into a sluggish nightmare, and it’s time we put an end to it.
Input lag, or input delay, is the time it takes for a signal from your source (like a PlayStation 5 or an Apple TV) to be processed by your television and displayed on the screen. Think of it as a delivery service. You place an order (press a button), and input lag is the total shipping and handling time before that order (the on-screen action) arrives at your doorstep. This is different from response time, which is how quickly a pixel can change color. A TV can have fantastic pixel response but still feel like you’re playing through molasses because of high input lag.
The Real Villain: Your TV’s Overeager Brain
So, what causes this delay? In a word: processing. Modern televisions are incredibly smart. They’re packed with powerful processors constantly working to make the picture look “better.” They apply motion smoothing to reduce judder, digital noise reduction to clean up imperfections, and dynamic contrast to make colors pop.
For a movie like Mad Max: Fury Road, this can be fantastic. The TV takes each frame, polishes it to a brilliant shine, and then serves it to you. But for gaming, this is a disaster. Each of those “improvements” is a computational step, and every step adds milliseconds of delay. It’s the digital equivalent of a chef insisting on garnishing every single grain of rice in a dish while you’re starving. The end result might look fancy, but it arrives way too late. This is the core issue you must tackle when learning how to fix tv input lag.
“We’ve entered an era of computational cinematography, where the television itself is the final director of the image. The challenge for viewers is reclaiming control, especially when interactivity is paramount. The conflict isn’t between a ‘good’ or ‘bad’ picture, but between a ‘passive’ picture and a ‘responsive’ one.” – Dr. Eleanor Vance, Media Technology Analyst
Your Action Plan: How to Fix TV Input Lag Step-by-Step
Ready to reclaim your reaction time? Follow these steps, from the simplest fix to the more advanced tweaks. We’ll get your TV feeling as snappy and responsive as it should.
1. The Silver Bullet: Activate Game Mode
This is, without a doubt, the single most important step. Nearly every modern TV has a “Game Mode” buried in its picture settings.
- What it does: Game Mode is a preset that tells your TV to stop thinking so much. It systematically disables most of the heavy video processing—motion smoothing, noise reduction, and other “enhancements”—that create lag. It prioritizes speed over everything else.
- How to find it: This varies by brand, but you’ll typically find it under
Settings > Picture > Picture ModeorSettings > General > External Device Manager. Look for an option explicitly labeled “Game Mode.” Some TVs with HDMI 2.1 even have an Auto Low Latency Mode (ALLM) that does this automatically when a console is detected.
Activating Game Mode can slash input lag from over 100 milliseconds (unplayable) down to 10-20ms (excellent). It’s the closest thing to a magic wand for this problem.
2. Scrutinize Your Connections: The HDMI Cable Matters
You wouldn’t put cheap tires on a Ferrari, so why use an ancient HDMI cable with your brand-new Xbox Series X? While any functional HDMI cable will work, using the right one ensures you’re not creating a bottleneck.
- For 4K @ 120Hz Gaming: If you have a PS5, Xbox Series X, or a high-end PC, you need an Ultra High Speed HDMI 2.1 cable. These are certified to handle the massive bandwidth required for next-gen features like 120fps and Variable Refresh Rate (VRR), both of which contribute to a smoother, more responsive feel.
- For everything else: A standard High Speed HDMI cable is usually fine, but if you’re experiencing issues, swapping it out for a newer, certified cable is a cheap and easy troubleshooting step.
3. Go Manual: Taming the Processing Beast Yourself
What if your TV is older and doesn’t have a Game Mode? Or what if you’re a tinkerer who wants to optimize further? You’ll have to go in and turn off the lag-inducing settings one by one. Dive into your TV’s advanced picture settings and look for anything that sounds like it’s “improving” or “smoothing” the image.
- Motion Smoothing / Motion Interpolation: This is the biggest offender, often called “Auto Motion Plus” (Samsung), “TruMotion” (LG), or “MotionFlow” (Sony). It causes the infamous “soap opera effect” and adds significant lag. Turn it off. Immediately.
- Digital Noise Reduction / MPEG Noise Reduction: These settings are designed to clean up low-quality broadcast signals. For a clean 4K signal from a console or streaming box, they are completely unnecessary and just add delay. Disable them.
- Dynamic Contrast / Black Enhancer: These features analyze the picture in real-time to adjust brightness and contrast. While it can make the image pop, that analysis takes time. Turn it off for the lowest lag.
- Edge Enhancement / Sharpness: Most TVs over-sharpen the image by default. This can create an artificial-looking halo around objects and is a form of processing. Lower the sharpness setting to a neutral point (often ‘0’ or ’50’, depending on the brand).

4. Don’t Forget the Source: Optimize Your Console/PC
The final piece of the puzzle is the device sending the signal. Both Sony and Microsoft have implemented settings to help you get the best performance from your TV.
- On PlayStation 5: Go to
Settings > Screen and Video > Video Outputand ensure ALLM is set to “Automatic.” - On Xbox Series X/S: Go to
Settings > General > TV & display options > Video Modesand check the boxes for “Allow auto low-latency mode” and “Allow variable refresh rate.”
These settings allow your console to communicate directly with your TV, telling it to switch into its fastest mode automatically.
Why Do My Movies Look “Wrong” in Game Mode?
You’ve followed the steps, your gaming experience is buttery smooth, but now you’ve switched over to watch Blade Runner 2049 and it looks… flat. A little dull, even. What gives?
This is perfectly normal. Remember, Game Mode’s job is to strip away the processing. That very same processing, while terrible for gaming, is often what gives cinematic content its rich, polished look. The solution is simple: switch out of Game Mode when you’re watching movies or TV shows.
For the best cinematic experience, look for a “Cinema” or “Filmmaker Mode.” Filmmaker Mode is a fantastic industry standard designed to show you content exactly as the director intended, disabling motion smoothing and other alterations while keeping the color and contrast processing that makes movies look great. Think of it as the “Game Mode for cinephiles.”
Frequently Asked Questions (FAQ)
What is a good input lag for gaming?
For most gamers, anything under 40ms is considered playable. Competitive players will want to aim for under 20ms. The best gaming TVs today can achieve input lag as low as 9-11ms in Game Mode.
Does 4K resolution increase input lag?
Not necessarily. While processing a 4K image is more demanding, modern TV processors are built for it. A well-designed 4K TV in Game Mode can have lower input lag than an older 1080p TV with its processing turned on.
Can a soundbar or AV receiver add to input lag?
Yes, it can. If your console is plugged into a receiver which then passes the video to the TV (a process called passthrough), the receiver itself can add a few milliseconds of lag. For the absolute lowest latency, connect your console directly to the TV’s best HDMI port and use ARC/eARC to send audio back to the soundbar or receiver.
How can I measure my TV’s input lag?
Professionals use specialized hardware like a Leo Bodnar Lag Tester. For a rough home test, you can use a laptop running a timer program, connect it to the TV in clone display mode, and take a photo of both screens simultaneously. The difference in the displayed time is your approximate input lag.
Will a more expensive TV automatically have lower input lag?
No. While flagship TVs often have the best gaming features and lowest lag, many budget-friendly models now offer excellent performance in Game Mode. Always check professional reviews from sites like Rtings.com, which provide detailed input lag measurements for nearly every TV on the market.
