LookUp Tables (LUT) and Intel® Graphics FAQ

Content Type: Product Information & Documentation | Article ID: 000028999 | Last Reviewed: 09/04/2024

What is a lookup table?

A lookup table (LUT) is an array of numbers that may be referred to by subscript. This avoids the recalculation of values each time a number in a table must be referred to. In computer graphics, you can use lookup tables to store the starting addresses of each line and the values corresponding to the placement of pixels within a byte.

Why would you need to know how many lookup tables are available in your graphics controller?

Professionals working with video- or image-editing software may need to calibrate their monitors to achieve the high level of color accuracy their work requires. Often, the graphics card needs to have more than one LUT in order to calibrate more than one monitor at a time.

What kind of hardware or software would typically require details about available LUTs?

Color calibration hardware and software, such as the Spyder5PRO* Family display calibrators, would need this information.

How can I tell how many LUTs are available in my Intel® Graphics controller?

You can find out by downloading this tool: GammaTest.

Note

This is a third party-controlled website and tool. Intel doesn't control the content that is available and it's simply being offered here for your convenience.

Move the Gamma Test window to a second screen. If you're able to individually turn each monitor magenta, you have multiple LUTs. If both monitors show magenta, you have only one LUT in your Intel Graphics controller.

Why is the information about the number of lookup tables not publicly available?

As color calibration hardware and software become more mainstream, we recognize the importance of having this information available and easy to find. Intel is currently working on making lookup table information available.
