Hey everyone!


Just two questions to ask:


First, is lumen rating on a logarithmic scale? I only ask this because I was sitting in my theatre, with a 600 lumen projector on a 120" matte white screen, with ambient light on it, enough to wash out the blacks. However, the rest of the colours were still pretty bright! So, I am amazed to consider what a 1000 or even 2000 lumen projector would look like in terms of brightness. Wouldn't this be way too bright in a dark room?


Second question:

What is the response time of the DILA panel, I know LCD is something like 100-200 ms, right? Please correct me if I am wrong. On that note, what is DLP respone time?


Thanks

Here is good reference that does an excellent job of explaining exactly what is a lumen.

David,


Response time for most LCDs is in the 16 milliseconds or so range. DMD full switch rate is 14 microseconds with an effective rate of 2 microseconds.
