DRA829J: DRA829 Screen Flickering when two screens interfaced

Part Number: DRA829J


Tool/software:

Dear TI team,

We are running QT based application on two monitors in the QNX environment. The primary monitor is connected via DisplayPort (DP)(1680x1050), while the secondary monitor is connected via HDMI(1920*1080) as shown .

During testing, we observed that both monitors flickering simultaneously if we use  both monitors . However, when the same software, with the same display load, is run on a single monitor, there is no flickering.

Since this issue occurs only in the dual-monitor setup, we would like to understand the probable reasons for this behavior. Additionally, we request your guidance on possible solutions to resolve this issue.

Please refer to the attached sample video for better clarity.
