I just read desray's blog on his new sony projector and he metioned that ideal lumens should hover around 1000-1300. Lumens beyond 2000 would have eye fatigue. Previously I used Optoma HD70 and has 1000 lumens. Screen from projector is about 3.2m and I had no eye fatigue. As I will be getting a new full hd projector and have lumens of 1800, I'm not sure would this brightness cause eye fatigue. Hope to get some comments from users who use 1800 lumens projector.
Having eye fatigue has more factor than just the lumen output from projector, the screen size, distance of view, screen gain , the screen characteristics type of source playback , time spent on using and human facial built on the different diopter's.These will be the factors that might or will cause eyes fatigue .Basically during the design process of your home theatre set up , there basic factors to consider . A) Room size B) Room environment and aesthetics.C) Screen size and propertie.D) Sitting distance E) Type of projectorF) Source most played or viewing .Hope that helps
It should be okay as long as the projector is meant for Home Theater viewing...just curious what projector are you using that have a published lumens of 1800? 3LCD?
Thanks for the reply. I'm looking at DLP projector.
Cool...I bet its a 3D projector? No?
Thanks alf for filling in the void on this projector lumens segment.
I find my new pj is too bright. I played around with the adjustment of the brightness and contrast and found that it only helped a bit.Is there any alternative to reduce the brightness?I read that some users used a ND2 filter to bring down the brightness. Anybody here is using this?
Haha...just as I suspected. I assumed you are already using the low/eco mode? ND2 does help to reduce the brightness output but you may not like the 'overall' effect it has over the projected image. Can your projector close the IRIS all the way down?
