DLP-Link Black Level Best black-level adjustments for DLP-Link glasses and projector?
After playing through [i]Dead Space[/i] on my Acer H5360 projector using DLP-link glasses, I've noticed that the black level is pretty poor. The image overall is good and bright, but in very dark areas (much of [i]Dead Space[/i], unfortunately), the blacks are washed-out. I've heard that this is a common problem with DLP-link technology, as the glasses are synched by white flashes introduced within the frames. Looking at the game running in 3D with my glasses off, it looks like a super-bright blurry mess.
Dark games look alright overall, but I'd like to improve them if possible. Is there any way to improve the black level by adjusting colors, maybe in the projector's OSD? I improved things somewhat by setting the OSD gamma setting to 3, which seems to be the optimal setting for my screen.
Does anyone out there using this or similar projectors have any configuration advice?

It is true that DLP link uses flashes, but this is not why you see washed out blacks. This is a misconception because people are using the wrong glasses or have not investigated/understand the technology properly.
Glasses designed for DLP link will block out the white signal light by timing the shutters perfectly.
As an experiment, activate your glasses and put on a 3D game. Look through the glasses and then without. You will see that the blacks are significantly better with the glasses on because the glasses are blocking the signal white light. Now switch your projector to non 3D 120Hz, (ie the projector is working at 120Hz but the blacks are still black, ie no signal is being sent... I can do this on my Viewsonic through the OSD).
Now your projector will be working at 120Hz but the image without the glasses shouldn't be washed out.
Now, your glasses will no longer sync. But for a fraction of a second they will. Look at the blacks without the glasses - they will be not washed out. Now look at the with the glasses, and they will be only as good as they were with the 3D vision mode enabled.
There is a reason for washed out blacks:
You can have 2 things but not both.
High brightness but washed out blacks (normal projectors).
Very dark blacks but low brightness (high end home theatre projectors).
You are seeing white because these projectors are designed for gaming. It's something we have to live with until better technology comes out.
If you prefer to see pure blacks then you will have to sacrifice brightness. Buy a smoke lens/darkening lens to put in front of your projector, or better yet, wear sunglasses under/over your 3D Vision glasses ;-)
