Question to everyone about firmware 1.05 issues:
Our third projector with firmware 1.05 starts and remains in, I'm guessing, normal lamp mode for a couple minutes and the "lamp power" option is NOT available in the settings during this time. After a couple minutes the option becomes available. I say it is probably in normal lamp mode because of the fan noise — it's running high. Did not notice this in the previous projectors.
Two, with lamp mode set to economic the fan is now the same level as when in normal lamp mode, only smarteco has a lower fan speed. The previous two projectors both were the quietest in economic lamp mode.Flickering
The last projector lamp would "pump" a little when switching to very bright screens, like when I would display the desktop with windows explorer open. You could visibly see the lamp changing brightness a couple times real quickly. Did not see that on the first or third projectors however, the first and third clearly do NOT have the same amount of lumens as the second (see below). However, can't say I've seen exactly what stuntman has seen on any of the projectors.FYI about the W1070's lumens
Now that we are on our third projector and have had some time with it, I believe their are two "models" of W1070 being shipped. I say this because our first and third projector are very close in lumens/brightness but the second was noticeably brighter. The second projector never needed to have gamma above 2.2, regardless of how much light was being let into the room — within reason, of course. Watching at 2.2 gamma in black-out conditions was too bright — at our temp 84" screen. The first and third need 2.2 for black-out conditions and even then I don't think it's as bright. Going with 2.4, even in black-out conditions, just isn't that bright — it is watchable but nowhere near the second projector's brightness — and it can't handle as much daylight into the room no matter what the gamma is set to.
Even though I set the second (brightest one we've had) and third projector (seems very similar to the first) side by side it was impossible for me to see just how bright they were because of limitations in the room and screen size; however, it was obvious that the third needed at least two points higher on brightness to even look similar in shadow detail. This is, honestly, a little disappointing
as the brighter projector was great for daylight living-room issues whereas the current one really needs the blinds fully closes so the least amount of light is let in.
I do believe this is why we are seeing some very different opinions of how much light this projector can handle and how bright it should be per screen size. Well, it's because some are getting brighter projectors than others.
This seems obvious when we compare the following two "pro" reviews
Rather surprisingly for a budget projector with a data grade history, it wasn't that bright as we were expecting and in the Economic lamp mode we were only getting around 900 lumens. If you switched to the Normal lamp mode, the brightness increased to 1,100 lumens but it was still a long way from the claimed 2,000 lumens.
Lumen Output and Color Temp at 100 IRE (mid zoom):
Dynamic= 1786 @ 7754
Standard= 1730 @ 6912
Cinema= 1711 @ 6913, 1109 @ 7359 with Eco lamp, 1335 @ 6566 with Normal lamp and Brilliant Color off.
User 1= 1730 @ 6897
User 2= 1730 @ 6904
They are getting, at a minimum, at least 200 lumen difference. . . if I'm reading everything correctly. However, I do believe we have seen this lumen issue with the three W1070's we've had.
