I'm running a firehawk with the 4900. Certainly, every pj has its drawbacks and I have not done anything to tweak the machine other than the putting the settings that were posted on post #1 or 2. These settings were reccomended for the 5000.
Thus far, I can say that for the price it is an excellent machine. The contrast is better than expected and 1080p from where I sit, 12' back on a 100" 16:9 screen is noticeable. To my eyes, the 1080p has a bit more pop and more saturated colors. The blacks are decent but short of mind boggling if you are highly contrast sensitive.
My room does have light ceilings but the screen wall is black and there is a shelf protruding over the screen that is 12" that is also black and helps to mute some of the incoming light. The pj is shelf mounted about 6" above the top of the image- This seems to cause a bit of a trapezoidal effect when trying to fill the screen perfectly with the grid. I don't think there is keystone on this machine. When I watch something, I can't notice. From what I can tell, there is not much, if any light reflecting off the ceiling which is 12" above the center of lens. For whatever reason, other PJs would throw more light at the ceiling.
As for blacks, my best point of reference is when the credits come on at the end of a movie as well as the bar on 2:35 material. During credits it truly looks far lighter than my wall or the velvet border on the scene. 2:35 bar are noticeable while RS-1 people laud their machine for not even noticing the bars thanks to contrast. I'm not sure how well an RS-1 would hold up for contrast in my place though, given the light ceiling.
Intrascene though the blacks are quite good, particularly when pitted against colors.
The colors are accurate and this, is exceptional given the brightness of the unit. The image is brighter than my epson in best watching modes, by a good stretch. I am a bit of a brightness fiend and I have the lamp on low now although the bulb is new.
If I had to complain, the iris is noticeable when it does it thing as I mentioned above. Being able to focus while watching an image would be better than on the grid. I don't think you can do this. The zoom could be a bit better as well- it does not seem to zoom out proportionately so filling the screen just right is tough. My placement may have something to do with this but given the amount of lens shift, one would think this would be easier. The horizontal lens shift is limited and AFAIK
, there is no way to tell when you are in the center of the shift. I would prefer to shift the pj an inch or two than use horizontal shifting.
I'll keep y'all posted as I go.
