How to Set Up a 65 Inch TV for Gaming? | Get It Right The First Time

Most people plug in their console, turn on the TV, and wonder why games feel laggy or why HDR looks washed out. The fix for a 65 inch TV for gaming isn’t complicated, but it does require specific settings on the right input. Missing even one step leaves performance on the table. Here’s the order that works.

Why The HDMI Port Matters More Than You Think

Not every HDMI port on a 65-inch TV supports the full feature set your console needs. On Samsung TVs, for example, the advanced gaming features only work when you enable Input Signal Plus on the exact port your console is plugged into. Skip this and the TV may cap the signal at a lower refresh rate or disable HDR entirely.

The rule is simple: check which port the manufacturer labels for gaming or high bandwidth, plug the console there, then enable the enhanced signal feature for that specific input. Samsung’s official guidance calls for Settings > General > External Device Manager > Input Signal Plus. Toggle it on for the port your console uses.

The common mistake is enabling the feature on one port while the console sits in another. The setting applies per input, not to the whole TV.

Turn On Game Mode For Low Latency

Game Mode is the single biggest difference between a crisp gaming experience and one that feels sluggish. It cuts the TV’s image processing to reduce input lag, which is the delay between pressing a button and seeing the action on screen.

On recent Samsung TVs, the path is Settings > General > External Device Manager > Game Mode Settings. Some models place it at Settings > Picture > Special Viewing Mode instead. Both do the same job.

One caveat most people miss: Game Mode only works for a PC or console connected to the TV. It’s not available from the tuner or USB sources, so don’t expect it for broadcast TV or media playback. When you enable it correctly, the TV will notify you that the mode is active for that input.

What About HDR And Refresh Rates?

HDR settings live in a different menu. On Samsung TVs, look in Settings > Picture > Expert Settings, where some models offer HDR+ Mode. That’s a TV-side enhancement, not the same as your console’s HDR output, which requires a game or app that supports HDR.

Refresh rate is where model differences become obvious. A 65-inch screen doesn’t automatically mean 120Hz or higher. Samsung’s U.S. gaming lineup includes 65-inch Neo QLED models with Motion Xcelerator 165Hz, while its 65-inch OLED models support 144Hz. LG’s U.S. gaming guide lists 120Hz as the standard with up to 165Hz on some TVs, and notes that 65-inch models can support VRR at 4K 144Hz, AMD FreeSync Premium, HGiG, ALLM, and eARC depending on the model family.

The list goes on. Panasonic’s UK gaming pages show 144Hz or 120Hz across its 65-inch Z95B, Z90B, W95B, and W85B series. TCL’s U.S. gaming page highlights 144Hz VRR and Game Master 2.0. Philips lists a 65-inch QLED model with 4K HDR and PMR120. None of these features are guaranteed by size alone, and even within one brand’s lineup, features vary by model family.

Setting Up A 65 Inch TV For Gaming: The Order That Works

Connect the console to the correct HDMI port, power everything on, then work through the settings in this order:

• Enable Input Signal Plus for the port your console uses.
• Turn on Game Mode from the External Device Manager menu.
• Check Expert Settings under Picture for HDR adjustments.
• Confirm the console’s output settings match what the TV supports for refresh rate and HDR.

When it’s done right, the TV recognizes the console, Game Mode activates automatically for that input, and games run at the panel’s rated refresh rate with HDR working as intended. When it’s wrong, the symptoms are obvious: laggy controls, dim HDR, or a signal that won’t reach the TV’s full capabilities.

The final check is the console itself. On a PlayStation 5 or Xbox Series X, the video output settings screen shows exactly what the TV is receiving. If it reports 60Hz when the panel supports 120Hz, the HDMI port or Input Signal Plus setting is almost certainly the culprit. That screen is your ground truth.
