Firmware Bug Report - LC49G95TSSNXZA PBP Mode Broken After v1020.0 Update

[user5w627guehd]

My product information:

• Model: Samsung LC49G95TSSNXZA (49" Odyssey G9)

• Firmware Version: M-T9549GGAA-1020.0

• System: ThinkPad P1 Gen 6 Intel with CalDigit TS4 Thunderbolt dock

• Connection: Dual DisplayPort cables

Issue Description:
After updating to firmware v1020.0, the Picture-by-Picture (PBP) mode no longer functions. When PBP mode is enabled with two DisplayPort cables connected, Windows displays only recognize one monitor output instead of two independent displays. This prevents PBP from operating, as the feature requires both inputs to be detected by the operating system.

Steps to Reproduce:

1. Connect two DisplayPort cables to the monitor

2. Enable PBP mode via OSD menu

3. Observe: Only one display is enumerated in Windows Display Settings

4. Expected: Two independent 24.5" displays should appear in Display Settings

Technical Details:
The issue appears to be related to EDID (Extended Display Identification Data) reporting in PBP mode. A temporary workaround exists: connecting an unused HDMI cable to the monitor restores EDID enumeration and allows PBP to function. However, this workaround triggers Samsung's multi-input setting restrictions, disabling access to Picture Modes and picture adjustment controls.

Impact:

• Core feature (PBP) non-functional with dual DisplayPort configuration

• Feature worked correctly on previous firmware versions

• Workaround eliminates access to picture customization settings

Request:
Please investigate this firmware regression and consider releasing an updated firmware version to resolve this issue.
