@Lesendover,

Welcome to our HP Community forum!

On the HP Pavilion All-in-One - 27-xa1023a, the three physical buttons on the right-hand edge are typically associated with monitor/display functions, not just PC controls. Depending on your exact model configuration, here's what those buttons generally do (from top to bottom):

1. Power Button – Turns the system (or just the display) on or off.

2. Menu/Input Button – Opens the on-screen display (OSD) menu or allows switching between video input sources (e.g., PC or HDMI-in if supported).

3. Navigation or Volume Buttons – These may function as up/down controls to navigate the OSD menu or directly adjust the monitor’s built-in speaker volume.

How to verify:

With the system powered on, press and hold the second or third button for about 1–2 seconds. If it brings up a menu overlay on the screen, these are OSD controls. If it adjusts volume directly, then the buttons are mapped for audio control.

Note: All-in-One PCs often share hardware features with standalone monitors, so it’s common for models like the 27-xa1023a to include display adjustment buttons on the chassis.

Let me know if you see an on-screen menu pop up -I can walk you through brightness, contrast, or input settings if needed.

Kind Regards,
