Hi All
Im trying to calibrate my projector and i have some questions

My Setup :
Projector - Epson Emp-82 ( color temp : 6500k , color mode : theatre )
Input - Vga
System -
Windows Vista 32Bit
Ati Radeon HD4670
Resolution : 1024x768 @85HZ

Im using AVS HD 709
I don't got a calibration device
Trying to do basic color calibration using these filters :
http://www.lightingelstore.com/servlet/the-257/VIDEO-CALIBRATION-PACK-%283%29/Detail

Running through media player classic ( hc ) with ffdshow ( rec 709 in settings )

Controls i have:
Saturation ( according to the manual ) control over red , blue and green from the projector
Master saturation and hue via "Avivo Color" from catalyst cc
And gamma , brightness , contrast for each color also from the ati catalyst cc

now before this try i did some "eyes" ( just by feeling ) calibration and got the colors saturation on my projector to :
red - -6
green - 2
blue - 6

i reset the color settings of course before i started
and i used the blue filter to get the overall saturation and hue settings with the "Flashing Color Bars" pattern ( Main Menu - Basic Settings ) and using "Avivo Color" from the catalyst cc

when i try to see "Flashing Primary Colors" pattern ( Main Menu - Misc. Patterns )
using the blue and red filter - flashing bars are almost the same as the vertical bar
using the green filter - way off and not even close to match

the color setting on the projector does nothing to it ( as far as i can see )

using the "Flashing Color Brightness" pattern after that i get 0 in the red and blue bars but about 14% high ( +30 ) using the green filter
lowering the green color in the projector to the min ( -16 ) lowered it to +24
the gamma , brightness and contrast controls in the catalyst cc effect this not like it supposed to look

after that i still had to change the color settings ( r:-6 , g:2 , b:6 ) to get a neutral picture as far as my eyes see

now what am i doing wrong?
is there a different way of controling r/g/b hue / saturation ? from the pc maybe?
do i use the wrong patterns or misunderstood them?
or can't i even do what im looking for without a calibration device?

thanks in advance ,
ofir

first off back everything off in the Catalyst control center.

Leave everything in your driver set neutral if you go futzing about in there you are really going to get a screwed up result.

Only adjust things in your projector.

In your projector only adjust
brightness
contrast
color
tint
sharpness
lamp
iris

Anything else requires at least a colorimeter to adjust.
