It’s very important for displays to have a strong ‘dynamic range’ between pure whites and deep blacks, preferably without ‘crushing’ gradations in blacks and ‘clipping’ in whites. If there’s not enough contrast, pictures can look washed and scenes can lose details impairing the overall viewing experience.

When asked initially: ‘Which display type offers the best level of contrast’ the responses were almost identical to response times as follows: LCD has the best contrast: 31 per cent. Plasma has the best contrast: 35 per cent. LCD and plasma are equal for contrast performance: 34 per cent

European mean scores:
Which display format is the best for contrast?

Before comparison:------------------------After comparison:

Plasma flat screen is best for this.

LCD flat screen is best for this.

LCD and plasma are equal for this.

Having seen the content, the respondents again re-evaluated their feedback with an increase of 26 per cent in the category of people who believe that plasma provides the best quality (to 61 per cent). LCD fell back slightly (31 to 26 per cent).

Note: Respondents were given the following explanation for contrast: The viewed image appears to have little or too much contrast. Images with too little contrast appear dull and grey. Those with too much contrast (which is less common) can be too bright in some areas and too dark in others.
