Have recently upgraded from a 350 lumens LCD projector to a 1100 lumens projector with 0 hrs on the bulb. The contrast has improved vastly and the image is sharper due to the higher resolution but I'm having a problem with blacks. The brighter bulb has made them significantly more grayish and whites are too white unless I turn the contrast down (which again makes the blacks worse) Now, I know that you can't get real black on an LCD projector but it is possible to improve things slightly by using various filters. I've read on here about the use of neutral density filters which lower the brightness slightly to create a better dark image? I have a feeling that this is the avenue I need to take since on bright scenes my front room lights up like a Christmas tree and dark scenes are not dark enough! Anyway, does anybody know anything about these filters - like do they come in different strengths? If so, how would I know which one to buy. Are these neutral density filters made of the same stuff that VDU screen anti-glare filters are made of? I have one of these lying around spare and was going to encase my projector and use the anti-glare filter as a window for the projector to shine through. Would I get a similar result from the anti-glare filter as one of these neutral density filters?
