Sound quality is distorted on a screen (9)

I believe the answer is:

resonance

I'm a little stuck... Click here to teach me more about this clue!

'sound quality' is the definition.
'resonance' can be an answer for 'quality' (resonance is a kind of quality). I am not certain of the 'sound' bit.

'distorted on a screen' is the wordplay.
'distorted' indicates an anagram.
'on'+'a'+'screen'='onascreen'
'onascreen' anagrammed gives 'RESONANCE'.

'is' acts as a link.

Can you help me to learn more?

(Other definitions for resonance that I've seen before include "Sonority" , "Deep, clear, ringing quality" , "Sound amplification" , "continuation of noise" , "Plangency" .)

I've seen this clue in The Globe and Mail.
