Summary
Information for Stereoscopic 3D (S3D) support on 12th generation and newer platforms including Intel Arc Discrete graphics

Description
Do the new Intel® ARC™ discrete graphics support 3D / quad-buffered stereoscopic rendering on Windows® 10/11?

Resolution
Stereoscopic 3D (S3D) support is discontinued from 12th generation Integrated Graphics and newer platforms including Intel Arc Discrete Graphics cards.

This results in the option in OS Display settings page for “3D Display mode” to be unavailable.

The stereo 3D (S3D) technology has been and continues to be supported on Intel® graphics via HDMI 1.4.

On some original equipment manufacturer (OEM) PC designs with 6th, 7th, and 8th Generation Intel® Core™ Processors, a LSPCON is used to convert a DisplayPort 1.2 signal to enable HDMI 2.0. This is a third-party integrated controller on the motherboard, and S3D is not supported in this scenario.

Our OEM partners have moved away from enabling this feature based on low customer demand. So S3D via HDMI 2.0 isn't currently supported on some 6th, 7th, and 8th Generation Intel® Core™ Processors

The detailed documentation of Intel Corp. for latest Intel Core Processors notes:

Display Technologies Support

HDMI 2.1 High-Definition Multimedia Interface Specification Version 2.1

Notes:

Processor support native HDMI 2.1 TMDS compatible ports
Processor support non-native HDMI 2.1 port by using DP to HDMI protocol converter.

--------------------------------------------------------------------------------

DP to HDMI protocol converter is also called LSPCON and it is used to convert DP signals into high-resolution HDMI 2.0 and HDMI 2.1 signals

His presence makes impossible Intel Stereoscopic S3D and its presence or absence is determined easily and quickly by the program
"Intel Graphics Control Center" from the Intel Corp. graphics driver package when generating a report file.

In the case of the above-mentioned intel community question from the "ssu.txt" file of the Intel® System Support Utility for Windows* report ( or Windows DxDiag report, or Intel Graphics Command Center -> Display -> Information -> Connector Type ), it appears that this ASUS PRIME Z690-P motherboard does not use LSPCON, and the absence of "3d display mode" is determined by the absence of it in the graphics of the 13th Generation Intel processor
