Should I use Game Mode or PC mode on TV?

Hey there! If you‘ve hooked up a gaming console or PC to your shiny new 4K TV, you may have noticed lag or input delay while playing games. Modern TVs come packed with image processing features that can make games feel sluggish and unresponsive.

Not to worry – special gaming modes built into your TV can help tackle this problem. In this guide, we‘ll take a comprehensive look at the two main settings: Game Mode and PC Mode. Here‘s what we‘ll cover:

What Causes Input Lag on TVs

Input lag refers to the delay between pressing a button on your controller and seeing the reaction on screen. In technical terms, it is the time it takes for your display to process and respond to an input signal.

On a responsive monitor, input lag can be as low as 10ms. But on a complex 4K TV, lag can reach up to 80ms without gaming modes enabled. That‘s nearly 1/10th of a second!

This lag is caused by all the sophisticated image processing modern TVs perform:

  • Scaling 1080p and 1440p sources up to 4K
  • Noise reduction and debanding filters
  • Motion smoothing techniques like black frame insertion
  • Advanced contrast and color enhancers

These features improve picture quality but take time to process each frame, increasing input lag. Game Mode offers a solution.

What Does Game Mode Do?

Game Mode is a setting available on most 4K TVs that optimizes the TV for gaming. According to Samsung, enabling Game Mode "bypasses much of the image processing, giving you the most responsive gameplay possible."

Specifically, Game Mode:

  • Disables post-processing effects like motion smoothing, noise reduction and contrast enhancers.
  • Minimizes video processing to reduce scaling latency.
  • Boosts refresh rate up to 120Hz on supported TVs.
  • Decreases input lag down to 10-20ms on better TV models.

The resulting picture may not look as refined, but Game Mode delivers a much more responsive gaming experience with silky smooth controls.

For example, LG‘s OLED TVs see their input lag reduced from 34ms in regular modes down to 13ms with Game Mode enabled, according to tests by RTings. That‘s a massive improvement in responsiveness!

How Does PC Mode Reduce Lag?

In addition to Game Mode, many TVs also offer a dedicated PC Mode that reduces lag for gaming while maintaining picture quality better.

According to HDTVTest, PC Mode "disables most of the heavy image processing, while retaining essential video processing that doesn’t contribute to additional latency."

Benefits of PC Mode include:

  • Low input lag around 13-25ms for responsive gaming.
  • Chroma 4:4:4 subsampling support for reading clear text.
  • Sharper image quality than Game Mode, retaining more essential processing.
  • Better color accuracy and screen uniformity.

The compromise is that enabling chroma 4:4:4 might add 2-3ms of delay compared to Game Mode. So hardcore competitive gamers will still want to use Game Mode.

But for most gaming and TV use, PC Mode strikes an excellent balance. Let‘s look at how the top brands implement it.

LG TVs – Game Mode vs PC Mode

LG‘s acclaimed OLED TVs offer excellent low lag Game Modes. According to RTings tests, enabling Game Mode drops input lag from 34ms to only 13ms – superbly responsive.

LG‘s Game Mode allows you to adjust basic picture settings like brightness and contrast. Unfortunately, you can‘t tweak more advanced options.

The PC Mode enables Chroma 4:4:4 subsampling for reading text clearly. However, image adjustments are still limited compared to regular picture modes.

Overall, LG TVs have outstanding gaming performance. Use Game Mode for fast-paced competitive gaming at 1080p or 1440p. Switch to PC mode for 4K gaming and desktop usage.

Samsung TVs – Game Mode vs PC Mode

Samsung‘s 2022 Neo QLED TVs have phenomenal input lag of only 9.3ms with Game Mode enabled, according to RTings. That‘s as responsive as many gaming monitors!

Samsung‘s Game Mode also provides the most tuning options. You can tweak settings for motion processing, local dimming, contrast and color accuracy.

The PC Mode enables chroma 4:4:4 support and retains more fine image processing without impacting input lag much. This prevents text fringing and maintains picture quality.

Overall, Samsung‘s Mini-LED TVs offer the best 4K big-screen gaming experience. Use Game Mode for fast gaming and PC mode for monitor use.

Sony TVs – Game Mode vs PC Mode

Sony‘s acclaimed OLED TVs reduce lag down to just 17ms with Game Mode, according to HDTVTest. The resulting motion clarity is remarkably fluid and responsive.

Sony‘s Game Mode also intelligently analyzes the content to optimize settings continually. You can manually select presets for different game genres too.

Their PC Mode retains excellent motion clarity while enabling 4:4:4 chroma. This balances low lag for gaming with enhanced picture processing for desktop usage.

Overall, Sony OLEDs are also excellent for big-screen 4K gaming. Use Game Mode for action gaming and PC mode as a monitor.

TV Gaming Mode Tips

Here are some additional tips to optimize your TV‘s gaming performance:

  • Enable ‘Auto Low Latency Mode‘ which automatically engages Game Mode when detecting a game signal.

  • Turn off Motion Blur reduction features that introduce input lag.

  • Set black frame insertion to Low for reduced strobe backlight flicker in Game Mode.

  • Match the console‘s output resolution to the TV‘s native resolution for minimal scaling.

  • Enable HDR for enhanced contrast and colors. Auto HDR tone mapping works well.

  • Use HDMI ports with the highest bandwidth like HDMI 4 for best performance.

PC Mode Setup and Usage Tips

To correctly set up and leverage PC Mode:

  • Set the TV input icon label to PC to enable proper chroma support.
  • Disable HDMI Ultra HD Deep Color to prevent chroma subsampling.
  • Match the TV‘s native 4K or 1080p resolution for maximum text clarity.
  • Adjust Overscan settings if game HUD elements are cut off.

PC Mode is great for console gaming too. The enhanced color and motion clarity over Game Mode can outweigh the minor added input lag.

Making The Most of Your TV for Gaming

  • Game Mode delivers the smoothest, most responsive competitive gaming experience. It remains ideal for fast-paced online action gaming.

  • PC Mode balances low lag gaming with enhanced picture quality and text clarity. It‘s excellent for single-player console gaming and desktop PC/monitor use.

  • Adjust your TV and console settings to complement these modes for the optimal experience.

We‘ve just scratched the surface of all the advanced gaming features modern TVs offer. For the best big-screen gaming experience, match your TV and console capabilities carefully and leverage the specialized Game and PC modes. This will transform even the most casual living room console setup into a highly responsive battlestation!
