Some of the guys who took this poll must be blind.

Nearly one out of five viewers cannot see the difference between high-definition (HD) and standard-def (SD) TV programmes, according to an informal online poll put up this month by UK-based computer magazine PC Advisor.

The PC Advisor web survey posed the question, “What do you think of HD TV?“. Out of 802 visitors who participated in the poll, 19% voted that “they can’t really see the difference”. 32.4% thought that high-def content is great, but a quarter (25.4% to be exact) of respondents said that it is not worth the extra money even though they like the effect.

8.4% of the respondents preferred “normal” standard-definition TV broadcast over high-def ones, although the increased costs of HD subscriptions and necessary equipments may have played a factor. The rest of the participants – 14.8% – said that they have never watched high-definition television programmes.
