projector brightness
if a projector bulb lasts for 4000 hours and yours is at 3000, is the picture brightness most likely dimmed from use? BFI depends on the hardware, right? otherwise you simply can't achieve projector-lightboost-like brightness, correct? it's amusing how projectors desperately require 1080p with the screen size being so much larger than a monitor, yet they are strictly limited to 720p 120hz. with the noise over increasing projector depth beyond 100%, to 300% even, i'm actually not able to increase mine beyond 80% without sync problems, whereas the monitor had no problems at 100% depth. i think it's worth pointing out that a 30" monitor will get you the same viewing area size as a 80"+ projection. being that the monitor is closer to you, it's screen is much "larger" than if it were placed all the way back on the same wall the projector is shined on.

Naturally a projector with a 3000 hour burn in is gonna look dimmer than a brand new, but my optoma hd67n was definitely bright enough even then. It helps if you are using high gain screen. I have no problems using 1080p projector at 720p or 1080p SBS. And my desktop monitor is 27" 1440p so its not like i havent experienced a higher res screen. Its not all about fov, i dont get the same kicks out of my xl2411t 3d monitor versus my 120" screen. Most important thing is a scale of things. I adjust depth and convergence to match my real life vision. With right settings, a projector 3d image can look so good and real, and the scale of the world/objects can look so lifelike. Imo not achievable on a monitor. Thats one of the reasons i dont use my 3dv2 monitor anymore. Even though the fov is almost the same, i always get the feeling that im controlling these little toy characters. 100% depth on a 24" monitor is too high for my taste too, doesnt look natural. i used to crank depth to 100-200%(depth hack) so ive gone that route too. Oculus rift gets the "scale thing" even better than pj setup imo.

[quote="sammy123"]100% depth on a 24" monitor is too high for my taste too, doesnt look natural.[/quote] i wasn't saying it was the monitor, but 100% depth on my projector is too high for some reason, the objects are too separated to sync properly, as i'm seeing many things in double so i have to reduce it to 75% or lower, any idea what could be wrong here?

What projector are we talking about, and are you using an EDID override or the depth hack?

For what it's worth as an example, I've never had any problems with brightness on my H5360. I run it against flat white paint wall, no special screen, 10' diagonal, 12' away. In normal mode it's actually too bright for me when I use it in 3D, so typically I run it in Eco mode for less fan, and less brightness. At the end of bulb lifetime, I notice it getting a little too dim, and put it back to normal mode to restore full brightness (and presumably hasten the demise of the aging bulb). Lastly, I don't notice resolution at all when gaming in 3D. The alternating viewpoints for each eye gives you double the resolution of 1280x720 for each frame. I would like 1080p, but really only for when I use it in 2D.

i'm also using the H5360, with the depth hack, no EDID override.
