Game Mode Game Mode (low-latency picture mode)

What Game Mode is

Game Mode is the picture preset that trades image processing for speed. A TV normally holds each incoming frame in a buffer while it runs motion interpolation, noise reduction, edge enhancement and dynamic contrast on it. Game Mode skips those stages so the frame goes from the HDMI input to the panel in a few milliseconds. The HDMI Forum describes the idea in its page on Auto Low Latency Mode: the ideal latency setting is, in many cases, what people call game mode, and it usually has to be set manually through menus and switched back for normal viewing.

The cost is a plainer picture. The same HDMI Forum page notes that a low-latency setting may not suit other kinds of viewing because some processing features are stopped to reduce latency. That is why the preset exists as a separate mode and not as the default.

How much lag Game Mode removes

The biggest single saving comes from motion smoothing. MakeUseOf reports that enabling motion smoothing at its highest setting can push input lag from a barely noticeable 10 to 15 ms to 100 ms or more, and that a TV in Game Mode might deliver around 10 to 15 ms, against 60 to 120 ms or worse in a default mode with smoothing cranked up. HowToGeek gives the lighter case: a few milliseconds shaved, such as 10 ms down to 6 ms, with high-end gaming sets reaching 1 ms. Those are ranges from publications, not one device measured before and after, and the gain on a given TV depends on how much processing its default mode runs.

Human thresholds explain why it matters. MakeUseOf says most players start noticing lag around 40 to 50 ms and skilled players can detect increases as small as 20 ms. A 60 Hz game produces a new frame every 16.7 ms and a 120 Hz game every 8.3 ms, so a display adding 80 ms is holding about five 60 Hz frames before showing any of them.

Game Mode vs ALLM

Game Mode is the destination and ALLM is the switch. ALLM is an HDMI 2.1 feature that lets a game console, PC or other source send a flag to the display, which then flips into its low-latency mode. When the source clears the flag, for example when you switch to a movie stream, the display returns to its previous picture mode. Trusted Reviews lists the Xbox One, Xbox Series X, Xbox Series S and PS5 as consoles that support ALLM, and it did not find a source indicating that the Nintendo Switch does. Sony calls its implementation Auto Genre Mode, which Trusted Reviews says appears designed to work with a PS5. The vast majority of Samsung, Hisense, Panasonic, TCL, Philips, LG and Toshiba sets support ALLM, while Roku TVs vary by model.

The HDMI Forum groups variable refresh rate and Quick Frame Transport with ALLM as its enhanced gaming features, and a display that supports VRR can respond faster still. See input lag for how the delay is measured.

Measured Game Mode latency on current TVs and projectors

Tom's Guide's lab measured input latency on five sets in one table: the Sony BRAVIA 9 II at 9.8 ms, the Samsung S95H at 9.7 ms, the Sony BRAVIA 7 II at 10.4 ms, the Hisense UR9 at 12.1 ms, and the older Sony BRAVIA 9 at 17.0 ms. The same lab measured the LG C6 at 12.9 ms in the standard path and 9.1 ms with Boost enabled, identical to the C5 and close to the C3's 9.2 ms. A 2 to 3 ms gap between the best sets is far below the 20 ms that skilled players can detect, so shop on VRR range and HDR behavior, not on small latency gaps. The best TV for gaming roundup and the PS5 Pro 120 Hz TV list cover which sets pair latency with 4K 120 Hz.

Projectors are slower. ProjectorCentral lists the Epson Home Cinema 5050UB at 22.5 ms for 4K/60 and 28 ms for 1080p/60, and the Sony VPL-XW5000ES at 21 ms for 4K/60. Both are roughly twice the 9.8 ms of the BRAVIA 9 II, so a projector suits slower story games better than competitive play, and the figure changes with the input mode, so check it for the resolution you will actually feed the projector.

Worked example: frames of delay

Divide the lag by the frame time to see what you feel. A 60 fps game on a set adding 100 ms of smoothing delay shows you the world six frames late (100 ms ÷ 16.7 ms). The same game in Game Mode on the Samsung S95H at 9.7 ms is under one frame late (9.7 ms ÷ 16.7 ms is 0.58). At 120 fps the unsmoothed 100 ms is 12 frames and the 9.7 ms Game Mode figure is 1.2 frames, which is why 120 Hz players should never leave a default picture mode on. Cloud services add network delay on top, so the display is only one slice of the total; see cloud gaming latency.

Common confusions

Game Mode is not Filmmaker Mode. Both switch off motion smoothing, but only Game Mode is built for latency, and I could not find a measured latency figure for Filmmaker Mode, so no number is given for it here. Game Mode is also not the same as a gaming-specific panel feature such as 120 Hz or VRR; it only stops the TV from sitting on frames. And turning it on does not guarantee low lag. The label alone proves little, so check a lab figure for your exact model before trusting it.

One side effect can be welcome. HowToGeek notes that if a 4K TV suffers from the soap-opera effect and its Game Mode strips interpolation, turning Game Mode on can reduce that effect. Picture tuning for film is covered in TV calibration settings.
