Gamma TV Setting (What Is Gamma Setting? What Setting For Gaming Or Movies?)

As an avid gamer and movie buff, I’ve often found myself frustrated trying to find the perfect picture settings for my display. I’ve done a lot of research and testing to find the best Gamma setting for gaming and movies, and I’m here to share what I’ve learned. Gamma setting is an important factor in getting the most out of your display, so it’s worth taking the time to understand what it is and what setting works best for gaming and movies.

In this blog post, I’ll explain what Gamma setting is and how you can use it to get the best viewing experience when playing games or watching films.

The gamma setting on your TV controls the transition from black to white, and values range between 1.8 and 2.4. Low values darken the image, making it more suitable for bright rooms. Low values make dark spots brighter and thus more suited to darker gaming or movie rooms. 

What is Gamma?Gamma (gamma correction) is a parameter setting on a TV that determines the brightness by controlling the transition of color from black to white.Understanding the gamma setting is crucial for getting the best viewing experience when playing games or watching movies. Typical gamma values range from 1.8 to 2.4.
EOTF vs. GammaEOTF (Electro-Optical Transfer Function) is a more advanced and accurate method of projecting color, commonly found in High Dynamic Range (HDR) TVs.EOTF utilizes mathematical calculations to transfer an electronic signal into the desired optical signal. It assigns electronic values to screen content representing brightness levels measured in nits, allowing for more accuracy compared to gamma settings.
Best Gamma SettingsThe ideal gamma value for gaming or watching movies depends on the lighting conditions in the room.For a room with a lot of light, use a gamma value of 2.1-2.2. For a room with less light, use a gamma value of BT.1886 (2.4). In addition to gamma settings, ensure your TV is set to Game Mode for gaming and Movie Mode for watching films. Game Mode reduces input lag and improves the gaming experience, while Movie Mode optimizes the viewing experience.
Other TV Features ImpactTV features like motion smoothness, noise reduction, and auto-brightness can cause input lag and affect the gaming experience.Disable these features for a better gaming experience. Also, look for features with keywords like motion, clarity, and smoothing, and disable them to improve the gaming experience further. Test the impact of disabling these features by playing a game before and after making changes.

What Is The Gamma TV Setting?

Gamma, more accurately gamma correction, is a parameter setting on your TV that determines the brightness on your TV screen by controlling the transition of color from black to white. 

Low gamma values make shadows darker, while high gamma values make dark regions lighter. You can see an illustration of different gamma values on the Gamma Wikipedia page. Gamma values require complicated mathematical calculations, but typical numbers range from 1.8 to 2.4. 

If you turn your gamma value up too high, the black areas on your TV display will turn gray, and the image quality will look washed out. However, lowering your gamma value too much will introduce clipping, which causes darker details to vanish and make the entire picture looks dark. 

For these reasons, a lower gamma setting is preferable in a room with a lot of light because it will make the picture a little darker and less taxing for your eyes. High gamma values are better for dark eyes because you can more easily see the darker areas of the screen. 

The gamma setting was a technological necessity for cathode-ray tube (CRT) TVs and video cameras. The human eye does not perceive light the same way TVs or cameras do, so these devices needed a setting to balance what the video signal was capturing and what the human eye was seeing. 

Nowadays, gamma’s current role revolves around adjusting brightness levels when a room is too bright or dark. It remains a modern-TV feature because TV show producers spent decades creating shows and other media content designed to work most effectively with gamma correction. 

What Is EOTF, And How Is It Different From Gamma?

Electro-Optical Transfer Function (EOTF) is more advanced than gamma because it can tell how many nits to produce instead of displaying a percentage of brightness. 

Electro-Optical Transfer Function (EOTF) is akin to gamma’s older and wiser sibling. It’s more accurate in its ability to project color and thus is becoming more popular with new TVs. 

EOTF is common in High Dynamic Range (HDR) TVs and uses data to display a specific brightness level. It utilizes mathematical calculations to transfer an electronic signal into the desired optical signal. 

It differs from gamma, which has a TV screen displaying only a percentage of brightness rather than precise and accurate data. The EOTF feature assigns electronic values to the screen content representing a brightness level measured in nits, which allows for more accuracy. 

What Is The Best TV Gamma Setting For Gaming Or Movies?

When you game, stream or watch movies on your TV, it is ideal to use a gamma value of 2.1 – 2.2 for a bright room and BT.1886 (2.4) for a room with less light. 

For a room with a lot of light, you want a value of 2.1-2.2 and 2.4 for less illuminated rooms; this applies to gaming, movies, TV shows, or streaming. Most people who try BT.1866 (equivalent to 2.4) appreciate the image quality so much that they never revert to 2.2 or below. 

It’s also crucial that you set your TV to Game Mode. Doing so will reduce your input lag and improve your gaming experience, albeit at a slight image quality loss. 

Most modern TVs have a plethora of features run in the background to make it convenient for the viewer, but they also demand a lot of your TV’s processing power to maintain. 

For instance, your TV may have an Automatic Brightness Control (ABC) feature that constantly adjusts your TV’s brightness as the room’s lighting changes. Gaming mode disables such features and allows your TV to focus solely on the task at hand or the current game you play.

Some of these features may be responsible for improving image quality, but for a gamer, improved input latency is much more valuable than image quality. 

Similarly, if you cycle through the different modes on your TV, you’ll eventually see a Movie Mode. In addition to adjusting the gamma as if you were in the cinema, it will also modify other picture features to optimize your viewing experience.  

What Other TV Features Affect Your Gaming Experience?

TV features like motion smoothness, NR Reduction, Mosquito Reduction, Noise Reduction, Auto-Brightness, and MPEG Reduction will cause input lag between your TV and gaming console. 

Most modern TVs have a slew of reduction settings hoping to throw the maximum amount of conveniences at the viewer. However, they give your TV more things to do, making it slower. 

These features don’t always have the same name, and manufacturers may name them differently, too, so finding them isn’t always easy. Some common ones include Mosquito Reduction, Noise Reduction, NR Reduction, and MPEG Reduction. 

Furthermore, any options that improve motion – whether features or modes – will drastically increase the millisecond (ms) response time between your TV and your gaming console. 

While motion settings have their place, most gamers want to disable them because they don’t see much use. Since manufacturers have different names for features, be on the lookout for those with keywords such as motion, clarity, and smoothing

If you spot a feature that looks like a culprit, test it by trying a game before and after you disable it. When you disable motion features, you can expect around an 80 – 100 percent performance improvement, sometimes even more. 


The gamma setting on your TV controls how your TV represents the color difference between black and white, ultimately affecting brightness. Its settings range from 1.8 – 2.4, with the lower number being brighter. You want lower values for dark gaming or movie rooms to see the dark regions on the screen.
