Hello
I have a Optoma 774N with 4300 ANSI Lumens.
I need it for a 5m diagonal, outdoor projection, but the brightness is not no good.
I've heard that the DLP's Lumens can be increased by removing the DLP Color Weel. Even if the image will not have the same nice colors, the lumens can double.
If someone had tried this or read about it, please advise of give a link.
Thank you

If the color wheel is removed you will only get a black and white image. There will be no color.
Most color wheels have 4 segments and they are divided into 7th's of a pie.
R - 2/7
G - 2/7
B - 2/7
Clear - 1/7
The clear section is added to increase brightness.
As an example say we have 1 pixel in the middle that is supposed to be a shade of brown. Insted of the mirror reflecting each color to make the brown it will reflect white for each color.
If you dont need color yes this will improve brightness around 30%. If you want color and brightness I would look into LCD they are much more efficient in the light they use unless you go to a 3chip DLP and thats gonna cost some$$$
