Masterpiece: Regarding environmental conditions.
The advantages of the OLED over a LED-LCD is negated in daytime bright room conditions.
In other words, in a bright room your perception of black is lifted, which narrows your perceptual dynamic range of the OLED(You won't be able to see dark gradations). The LED-LCDS can run brighter and consequently have better dynamic range in bright rooms.
The main problem for LED-LCD is viewing angle, but if you are fighting daylight the LED-LCD is still better.
Thanks Masterpiece - do you have any thoughts how brightness for OLEDs compare against brightness for the Panny neo plasmas?
