Screen Display not visible after updating OBS [Solved]

Recently I updated OBS to 29.1.2. After updating the software my screen display is not showing in the OBS software. I don’t have an additional video input device attached to my system but by default, my computer screen was coming before the update.

Solution:

In the Source section, there are two options. Video Capture Device which is mainly used if any video feed needs to be captured from a camera. Another option is Display capture. This is used for screen capture. Click on Display Capture. Display option will appear to select. In my case, an additional monitor (LG Ultrawide) is attached to my laptop. So two options are coming, one is my laptop screen another is the additional monitor. Select whichever you want to capture. Issue solved.
