UGR
Zgodnie z tabelami UGR, przynajmniej w przypadku niektórych
modeli lub konfiguracji w ramach rodziny, dość łatwo
jest osiągnąć UGR <16. Jest to wskazanie, a nie ścisły pomiar.
According to UGR tables, at least in the case of certain
models or configurations within the family, it is relatively easy
to achieve UGR < 16. It is an indication, not a strict measure.
