Užmečiau dar į 55VT50B apžvalgą:
"If you need a brighter image during the day, the THX Cinema mode delivered 
around 95 cd/m2 and THX Bright Room could put out a blistering 150 cd/m2."

Ištrauka iš 50GT50B:
"THX Cinema mode at 40 fL (apie 137 cdm2) and the THX Bright Room mode at 65 
fL (apie 220 cdm2 - čia jau galima drąsiai akis varvinti :) ), which frankly 
are probably a bit too bright."

Viskas -/+ normaliai su skaisčiu GT/VT50 modeliuose dieniniam žiūrėjimui, 
jei jau taip norisi didelio skaisčio ...
