Hi all. I am coming up on 1 year of using an Epson 8350 to power my 150" screen in my dedicated home theater room (fully light controlled). I am considering upgrading in the near future, but I have a few questions that I can't quite figure out from reading existing topics.
When it comes to having "enough" brightness for a 150" screen, how do you determine this? My projector currently sits about 12.5' from the screen and thus I am zoomed all the way to telephoto on the lens' 2.1x zoom. Now I know this closes down the iris some and costs me some brightness, but I also know that distance from the screen costs you brightness as well. So would it be brighter to fill a 150" screen zoomed to 1x on the lens but 20+ feet away, or 2.1x zoomed and only 12 or so feet away?
Secondly, unfortunately for me I cannot stand the sound of my epson 8350 on high powered lamp mode. The higher fan speeds being louder are less ideal, but I could live with that since it is constant. What I cant stand is that there is this pulsing noise that is higher pitched that accompanies the increased fan speeds that is absolutely not there in ECO mode. So while I think I prefer the brightness overall for movies in High lamp mode (using cinema preset with calibration tweaks), I just can't stand the droning audio pulse noise, so I am losing even a bit more brightness from ECO mode.
That said, how bright is bright enough? I can't really tell how to measure footcandles etc (although I do have a lightmeter app installed on my iPhone that I BELIEVE is giving me a footcandles reading of about 7 or 8 in my current setup). I know this stuff is all subjective and eye of the beholder, but regarding an ideal or attempted objective calibration, what should I be shooting for and what can I hope to achieve in brightness if I make a projector upgrade? I think my setup could benefit from some added brightness (such as slightly prefering the look of High lamp over ECO mode on my 8350), but in general bright daylight scenes are fairly bright even as is.
The model I am leaning heavily towards is the JVC x30 for what appears to be a much higher 2d lumen value in its best mode (which I am unsure if this is eco or high powered lamp) while maintaining a near silent audible operating sound level and great black levels/contrast. I am also considering the panny ae8000 and the epson 5020ub, but I am concerned with both the epson and panny that they wont be much brighter in best modes, and if I run high lamp mode, I may not be able to stand the increase audio sound levels (it all depends on how it actually sounds I suppose).
Any information on this would be greatly appreciated, as to how people make determinations on brightness per screen size per distance from screen per lens zoom per lamp lumens, etc lol. Thanks so much for any input!
(side note, I created a custom painted screen at close to 1.0 gain. I started with a slightly glossy satin finish pure white paint from sherman-williams, but there was always hot spotting on bright scenes and I couldn't accept that tradeoff for a slight brightness boost over a more matte finish)
