[QUOTE="chrisc, post: 788221, member: 746"] A good Optoma HD projector does not suffer from the washed-out blacks you mention. Check the contrast ratio. It will vary from 1200:1 for a cheapie to 40 000:1 for a good HD projector. A good screen helps a lot too, not just a white wall However, at the Montagu museum it was impossible to mount a screen so we painted the wall with 4 coats of Dekro "Hydrocide" paint. This contains flourescers and and an anti-fungal additive, more so than Plascon Wall and All and this was 95% as good as a portable screen which was tried at the same time. We used a photographic light meter to measure the reflection from the painted wall and the screen and it was very close [/QUOTE]
