Dobrý den, rád bych se informoval, jak je to s pozorovacími úhly v praxi. Sám mám doma levné plátno z čínského obchodu, které při pohledu od projektoru zobrazuje velmi pěkně, ale stačí se posunout o cca půl metru až metr v jakémkoliv směru od projektoru a rázem se snižuje světelnost i zhoršuje barevné podání. Tak nevím, zda je to standardní fyzikální zákonitost a nebo prostě třeba právě toto plátno je na tom lépe. Může být kvalita obrazu stejná nebo alespoň podobná i když se divák nebude koukat na obraz ze stejného úhlu jako ja vůči plátnu projektor? Děkuji za odpovědi.
