Greetings to everyone at this great forum.
I'm looking to purchase a projector which I'm planning to use primarily as a monitor. This is needed to negate two factors that, I think, are killing my deteriorating vision, namely near-work and looking directly into the light source. As it is, I'm not at all conserned about projector weight, dimensions and noise level. Refresh rate and color precision play only a minor part. Lumen output and contrast ratio are not critical as I can make a room as dark as needed. I do want the 1920x1080 resolution if possible, because I often work with large images and HD video, but I'm primarily concerned about the projector lifespan (I'd like to use it for about 8 hours a day if my eyes ever allow that) and the sharpness of the image it produces.
As far as I understand, when sticking to the 1920x1080 resolution and eliminating bulb-lit models because of their short lifespan, I only have the choise between the very dubious 3LED+3LCD based CRE X1000 from China and various not-quite-out-yet DLP based LED/Laser hybrids like Acer K750, ViewSonic PRO9000, Panasonic PT-RZ470K/W & PT-RZ370 and probably several other similar models I don't yet know about.
The choise in favor of LED/Laser DLP seems obvious as, being one chip based, they aren't going to have any misconvergence and are certainly produced with infinetely better quality control than the CRE. However, I'm alarmed by the reports about the short lifespan of DLP chips when used intensively. Here is one example. I've seen many other reports of DLP chip degradation starting after about 5000 hours of use, especially under high temperature conditions.
Can anyone confirm or disprove my suspicion or tell me about some other factors that are yet unknown to me? I'm especially interested in Bohanna's advice as he appears to have dealt with more projectors than anyone on this forum, so he probably has a better picture regarding their lifespan than most.
