For the most responsive Super Smash Bros. Ultimate setup, set the TV input connected to your Switch dock to Game Mode (or the TV’s equivalent), disable motion smoothing and optional picture processing, and connect the dock directly to the TV while troubleshooting. On the Switch, use TV Resolution: Automatic as the starting point and RGB Range: Automatic. These choices can reduce avoidable display processing; they cannot remove delay from the game, controller, or an online connection.
| Device or setting | Recommended starting point | What it does |
|---|---|---|
| TV picture mode | Game, Game Mode, Game Optimizer, or the model’s low-latency mode | Uses the TV’s gaming picture path, which is designed to reduce display delay on supported models. |
| Motion smoothing | Off | Prevents optional frame interpolation from being applied to the game picture. |
| Other picture enhancements | Off if the TV allows it in Game Mode | Avoids extra image adjustments that are not needed for a clean HDMI game signal. |
| Switch TV Resolution | Automatic; use 1080p if you need to troubleshoot a handshake or scaling issue | Sets the docked console’s output resolution. It is not a frame-rate or input-lag control. |
| Switch RGB Range | Automatic | Matches the video black-to-white levels with the display; it does not make inputs faster. |
| HDMI connection | Dock directly to the TV for the baseline test | Makes it easier to identify whether a receiver, switch, or other device affects the signal. |
Open the TV’s picture settings while the Switch is connected and choose Game, Game Mode, or a similarly named gaming preset. The menu path and label depend on the brand and model. Some TVs save picture settings separately for each HDMI port, so verify the mode on the input the dock actually uses.
Game Mode reduces or bypasses some picture processing that can add time before an image appears. Sony’s support instructions, for example, tell owners of supported BRAVIA and Google TV models to select the Game picture mode to reduce input lag; Sony also notes that the steps vary by model. Treat your TV’s manual as the authority for its menu names and features.
If your TV supports Auto Low Latency Mode (ALLM), it may switch to a low-latency picture mode when it detects a compatible source. ALLM support depends on the TV and connected device. Nintendo’s Switch TV Settings guide lists resolution and RGB range among its console options, but does not provide an ALLM switch setting. If the TV does not enter Game Mode automatically, set the TV mode manually. See Sony’s model-specific guidance for reducing input lag and LG’s explanation of ALLM.
Game Mode can make the image look different from Cinema or Standard mode because it may reduce some image adjustments. That is expected. Keep the gaming preset active for Smash, and use another picture mode for movies if you prefer a more processed look.
Turn off motion interpolation, which may be called Motionflow, TruMotion, Game Motion Plus, or another brand-specific name. It creates or adjusts frames to smooth motion and is unnecessary for reading the Switch’s original game frames. Sony’s guidance for certain older Android TV models specifically recommends turning Motionflow off for HDR games. Many newer TVs disable or lock motion options automatically in Game Mode.
If the TV still allows them, switch off optional noise reduction, MPEG noise filtering, dynamic contrast, and extra sharpening or “super resolution” effects for the console input. These settings change the image, and their availability varies by model. If a control is grayed out in Game Mode, leave it alone; there is no need to hunt for a setting the TV has already disabled.
Leave brightness, backlight, and color temperature at comfortable levels. Extreme picture values do not make controller inputs register faster, and changing many settings at once makes it harder to tell what helped.
On a dockable Nintendo Switch or Switch OLED, open System Settings → TV Settings. Nintendo lists TV Resolution options of Automatic, 480p, 720p, and 1080p, and RGB Range options of Automatic, Full Range, and Limited Range. The official Nintendo TV Settings guide includes the menu steps. Nintendo Switch Lite does not support TV Mode.
Start with TV Resolution: Automatic. If the TV reports an unstable connection or the picture is being scaled unexpectedly, test 1080p on a display that supports it. Choosing 480p or 720p does not guarantee lower input lag: the TV may scale the lower-resolution signal, and the result depends on the TV’s processing path. A 4K TV can upscale the Switch’s signal to fill its panel; that does not mean the Switch is rendering the game at 4K.
Keep RGB Range: Automatic unless you see a clear black-level mismatch. RGB range controls how video levels are represented, not response speed. If blacks look gray or shadow detail disappears, check the TV’s HDMI black-level or range setting and match it to the console. A mismatched range can make the picture look washed out or crushed.
A 120 Hz television also does not make the original docked Switch output 120 frames per second. Nintendo lists its maximum TV-mode video output as 1920 × 1080 at 60 fps. The panel’s refresh-rate capability and the console’s output are separate specifications; do not buy a higher-refresh TV expecting that setting alone to change Smash’s frame rate. See Nintendo’s published Switch specifications.
For a clean baseline, run one HDMI cable from the dock straight to the TV. If your usual setup passes through an AV receiver, soundbar, HDMI switch, capture device, or wall plate, temporarily bypass it. Those devices do not always add delay, but removing them simplifies troubleshooting. If the direct connection feels more responsive, check the device’s own Game, passthrough, or low-latency setting before restoring it to the chain.
Test in Training or a local Versus match rather than judging only from online matches. Repeat the same movement with the same controller and change one setting at a time: Game Mode first, motion smoothing second, and the HDMI route third. This is a practical comparison, not a millisecond measurement. Keep the settings that make the response feel consistent.
The TV affects the display portion of the response chain. Game Mode and reduced picture processing can shorten that portion on supported models, but they do not change Smash’s game logic, controller behavior, or online network conditions. If local play feels responsive while online matches feel delayed, the difference may come from the connection or match conditions rather than the TV. If local play still feels sluggish after the baseline changes, check the controller separately and confirm the dock is connected to the intended HDMI input.
Nintendo lists Super Smash Bros. Ultimate Ver. 13.0.5, released September 1, 2026, as fixing behavior involving invalid data sent or received in online battles. The published notes do not describe a TV-latency change. If you want to keep replays, Nintendo advises converting them to video before updating because replay compatibility may change.
