BenQ W1070 Projector Calibration and Settings 2

Posted on June 7, 2013 by Art Feierman

BenQ W1070 Post Calibration Grayscale: User Mode

Color Temp over IRE Range (Post calibration) User 1:
20 IRE = 6427
30 IRE = 6427
40 IRE = 6496
50 IRE = 6449
60 IRE = 6477
70 IRE = 6419
80 IRE = 6452
90 IRE = 6469
100 IRE = 6499
 Average gamma = 2.16

Calibrated color temps, 20 – 100 IRE:

Gamma proved to be rather good, and very close to the targeted 2.2. Mike had this to say about the gamma: Using the 2.2 gamma setting results in an average gamma or 2.16. The next step is 2.4, which results in an average gamma of about 2.36, which may be too dark.

To try these, open the menus, and from the Image menu, select Cinema mode.  Then go down to Advanced. Open it, then select RGB.  Place these number in, replacing the defaults.  The improvements should be pretty obvious.  We recommend you then save your settings under User 1.

W1070 Post Calibration settings

Calibration settings for User 1:
Gain (50) R = 51
G = 50
B = 49
Offset (256) R = 256
G = 256
B = 256
 Average gamma = 2.16

W1070 Calibrated Brightness in Lumens:  100 IRE: 1711 @ 6668

That's a whole lot of calibrated lumens!

Mike provided these additional notes, regarding the ability to calibrate different settings, limitations, etc.:

NOTE:  There was no reason to do a Quick Cal of the brightest mode (Dynamic) as it’s only 56 lumens brighter than User 1 to begin with.

The W1070 has amazingly good RGB balance right out of the box and almost perfect with just a few minor adjustments to the Gain.  If you see a little red in the light grays, you could even forego adjusting the Red gain, just turn Blue down one notch and end up with an RGB balance that beats a lot of pricier projectors after calibration.  Color looks pretty good with adjustment, but you easily turn down the Red in the CMS if you think it’s a bit too much. 

Mike reports the CIE chart looks much better than the last affordable BenQ projector he worked with:  This is a big improvement over the W1200 reviewed last year.
