Optoma HD70 Calibration

jaysonbarnett · December 2008

I was just wondering if anyone has calibrated a projector. I have an optoma hd70 and got digital video essentials blue-ray from netflix, but i notice in my optoma menu there is red, blue, green, (controls) which i understand but there is other funtion which i do not. Under the color settings there are other ones which say red bias , green bias, and blue bias. In other words does anyone know what that means and will the calibration dvd do those color settings as well. here are some pics of my ghetto theater.
If someone has calibrated this projector or can explain the bias settings and any advice for my first video calibration that would be great.
Happy holidays

For decent calibration I recommend

and that you follow

Have you checked in at the AVSforum? I am sure they have an official post for your proj.

You need to get comfortable with the menus and what the features do. Stay away from the service menus unless you know what you're doing but you could get there.

Yes i have but the posts are about what settings they have for the optoma, but nothing about how to calibrate it yourself.

I quess the question i have is: is there any tricks i can use with the calibration disk and why is there two adjustments for the same color (red and red bias) what is the difference between the two?

In my TV the red, blue, and green controls colors in bright scenes and the Bias controls are for colors in darker scenes.

Here is a link from a guy who has calibrated his PJ, http://www.avsforum.com/avs-vb/showthread.php?p=14889528#post14889528

Can not answer your question about the difference in color but here would be a great place to ask http://www.avsforum.com/avs-vb/showthread.php?t=729665&page=78

Agreed, each unit is different.
