Color & Audio Output Issues for A+
Short answer
Support-usable idea: A display may show an image but with wrong color or have no audio even though video is present. Technician steps: verify cable type supports audio (HDMI carries audio, VGA does not), check source color profile and display color settings, try alternate cables or sources, and confirm system audio output device settings.
Why it appears on the exam
- Identify whether an audio or color symptom belongs to the display/projector domain versus source/device settings. - Given a scenario where HDMI carries video but no sound is heard, select 'verify audio output selection on source' as first action. - Choose the likely cause of a color cast when a converter is used between source and display.
Key concepts
Concept 1
Required terms
incorrect color display: Colors appear wrong, oversaturated, undersaturated, or with color casts due to signal, settings, or display processing. audio issues: missing or distorted audio coming from a display's speakers or from audio passed through the display connection
Example
HDMI-connected laptop shows video but no sound because system audio is still set to laptop speakers; switching output to HDMI fixes it.

How Color & Audio Output Issues works
Support-usable idea: A display may show an image but with wrong color or have no audio even though video is present. Technician steps: verify cable type supports audio (HDMI carries audio, VGA does not), check source color profile and display color settings, try alternate cables or sources, and confirm system audio output device settings.
Example
Colors have a blue cast after connecting through a converter; swapping to a direct HDMI cable or checking display color presets resolves it.
Concept 3
Common confusion
Technicians sometimes assume missing audio means display speakers are faulty; often the OS or source device is routing audio elsewhere. Color issues are sometimes blamed on the display when the source or cable is to blame; always isolate.
Example
Monitor has wrong color because the source is sending a non-native color space; changing resolution/profile corrects color.
