Shulou(Shulou.com)11/24 Report--

CTOnews.com, Nov. 16, recently, Intel submitted new code for Lunar Lake's Linux GPU driver, indicating that Lunar Lake will introduce the CMRR (content matching refresh rate) feature as an extension of the existing adaptive synchronous variable refresh rate (VRR) feature.

The open source Linux graphics driver code has selected CMRR as the Intel display version 20 feature. Display version 20 is suitable for Lunar Lake Xe2 set display. However, this CMRR function may also appear in other hardware, such as the next generation unique.

However, these drivers have not yet been officially released, and we can only speculate from the comments in the update itself. From a naming point of view, CMRR should be a display technology similar to AMD FreeSync and Nvidia G-Sync.

Intel patched the Linux graphics card driver, which simply describes CMRR as:

CMRR is a display feature that uses an adaptive synchronization framework to slightly alter the Vtotal to exactly match the content rate without losing frames. This feature is a variant of VRR that uses an adaptive synchronization framework to slightly alter the Vtotal (between an additional 0 to 1 Vtotal scan line) to accurately match the content rate without frame loss.

The details of this function are not clear, and Vtotal seems to refer to vertical summation (Vertical Total), a term related to display technology. CMRR may be designed to reduce screen flicker without affecting the frame rate.

If nothing happens, Lunar Lake will be released in the second half of 2024, and Linux's steady updates to various applications and drivers show that the development of Lunar Lake is going well, and CTOnews.com will keep an eye on it.
