TV Input Lag Explained: How It Affects You & How to Fix It
Input lag—also known as input latency or input delay—is a crucial factor affecting user experience, especially for gamers and those who rely on responsive Smart TV navigation. In simple terms, input lag refers to the time delay between pressing a button on a remote or controller and seeing the corresponding action on the screen. While most computer monitors are optimized for low latency, TVs—particularly older models—often struggle with this issue.
For gamers, input lag can make the difference between victory and defeat, as even a slight delay can impact reaction time in fast-paced games. Similarly, for Smart TV users, high input lag can lead to sluggish menu navigation and an overall frustrating experience

Tips to Reduce Input Lag on Your TV
Input lag can significantly impact your viewing and gaming experience, but there are several ways to minimize it. Below, we outline practical tips and strategies to help you achieve the lowest possible input lag on your TV:
1. Enable Game Mode
One of the simplest and most effective ways to reduce input lag is by activating Game Mode on your TV.
- What is Game Mode?
Game Mode disables many of the TV’s image processing features, such as motion smoothing, upscaling, and noise reduction, which prioritize picture quality but add delay. - How to Enable It:
Check your TV’s settings menu (often under Picture or Display options) and toggle Game Mode on. Some TVs automatically enable Game Mode when connected to a console, so ensure this feature is enabled if your TV supports it.
Tip: On some TVs, you can customize Game Mode settings to balance speed and visual quality. Experiment with these adjustments to find what works best for you.
2. Lower the Resolution and Disable HDR
While 4K resolution and HDR (High Dynamic Range) deliver stunning visuals, they require significant processing power, which can increase input lag.
- Lowering Resolution:
If you’re experiencing high input lag, consider reducing the resolution to 1080p or 720p, especially if your gaming console or PC can handle these resolutions more efficiently. - Disabling HDR:
HDR enhances contrast and brightness but can introduce extra latency. Disabling HDR from your TV settings or gaming console can reduce processing delays.
Tip: If you’re gaming competitively, prioritize performance over visual enhancements. You can always re-enable HDR for single-player or cinematic experiences.
3. Use High-Quality HDMI Cables
The type of HDMI cable you use plays a crucial role in reducing input lag.
- Upgrade to HDMI 2.0 or HDMI 2.1:
Older HDMI cables (such as HDMI 1.4) may not handle high refresh rates or resolutions efficiently, leading to increased lag. HDMI 2.0 and HDMI 2.1 cables are designed for higher bandwidth and support features like Variable Refresh Rate (VRR) and 4K at 120Hz, which can significantly reduce latency. - Cable Length Matters:
Keep HDMI cable lengths short when possible, as long cables can sometimes degrade signal quality and introduce latency.
Tip: Get the most out of your console with a high-speed HDMI 2.1 cable! Experience 4K & 8K resolution, 120Hz refresh rates, and ultra-low latency for smooth, lag-free gameplay. Upgrade your setup now on Amazon* (Affiliate Link)!
4. Update Your TV's Firmware
Manufacturers frequently release software updates to improve TV performance, including input lag.
- How to Update:
- Check the system or support section of your TV’s menu for updates.
- Alternatively, visit the manufacturer’s website, download the firmware, and update via USB if needed.
- Why It Matters:
Firmware updates often include bug fixes, performance optimizations, and new features like improved Game Mode functionality.
Tip: Enable automatic updates on your TV to ensure you’re always running the latest software version.
5. Adjust Refresh Rate Settings
If your TV supports variable refresh rate (VRR) or high refresh rates like 120Hz, enable these features for smoother and faster performance.
- Match the Refresh Rate to the Source:
Ensure your TV’s refresh rate matches the output of your gaming console or PC. For example, if your console outputs at 60Hz, set your TV to 60Hz for optimal performance. - Enable VRR:
TVs with VRR can dynamically adjust their refresh rates to match the frame rate of your game, reducing screen tearing and input lag.
Tip: Not all TVs support VRR. Check your TV’s specifications or use a compatible gaming monitor if VRR is critical for your needs.
6. Optimize Your Gaming Console or PC Settings
Your gaming device settings can also contribute to input lag. Here’s what to do:
- Set Output Resolution and Refresh Rate:
Ensure your console or PC is set to output a resolution and refresh rate that your TV can handle efficiently (e.g., 1080p at 60Hz). - Disable Extra Visual Features:
Features like motion blur, anti-aliasing, and V-Sync on your gaming device can add processing time. Disabling them can reduce latency. - Enable Performance Modes:
Many consoles and PCs offer performance modes that prioritize frame rate and responsiveness over graphical fidelity.
Tip: Test different settings to find the ideal balance between visuals and responsiveness.
7. Minimize External Devices and Signal Delays
Sometimes, external devices and configurations can add unnecessary latency.
- Connect Directly to the TV:
If possible, connect your gaming device directly to the TV instead of routing it through receivers or soundbars. Intermediate devices can introduce additional delays. - Use Low-Latency Accessories:
Some gaming controllers or peripherals can add input lag. Choose accessories designed for low latency and wired connections whenever possible.
Tip: Test your setup with minimal devices to identify if any particular component is causing lag.
8. Disable Additional TV Features
Modern TVs come with several features designed to enhance picture quality, but they often increase processing time.
- Motion Smoothing:
Turn off motion smoothing or interpolation (often called “TruMotion,” “MotionFlow,” or similar names), as it increases input lag by adding frames to your content. - Noise Reduction and Upscaling:
Disable noise reduction and resolution upscaling in the TV settings, as these processes require additional processing power.
Tip: Look for a “Game Optimizer” or similar preset that disables most unnecessary features automatically.
9. Consider Upgrading Your TV
If you’ve tried all the above tips and still experience high input lag, it might be time to invest in a new TV designed for low latency.
- Look for TVs with:
- Input lag below 15ms (ideal for gaming).
- Features like ALLM (Auto Low Latency Mode), VRR, and Game Mode.
- High refresh rates (120Hz or higher).

| 21-40 ms | Good for slower games but noticeable for highly competitive players |
| >40 ms | May lead to noticeable delay, especially in fast-paced games |
For gamers, input lag is a game-changer—literally. In fast-paced games such as shooters or fighting games, even a small delay can severely disrupt gameplay and affect performance. A low-latency TV ensures a smoother, more immersive experience, giving players a competitive edge.
Emerging Trends in Low-Latency TVs
- 144 Hz Refresh Rate: High-end TVs now offer refresh rates of 120 Hz or even 144 Hz, significantly enhancing gaming performance. Higher refresh rates result in smoother visuals and reduced input lag, making these TVs a top choice for gamers.
- NVIDIA G-Sync and AMD FreeSync: Originally designed for computer monitors, NVIDIA G-Sync and AMD FreeSync technologies are now available in some TVs. These features sync the TV’s refresh rate with the device output, eliminating screen tearing and reducing input lag for a more fluid gaming experience.
