W5000 Projector Measurements and Calibration-2
|White (100 IRE)||6724K|
|Light gray (80 IRE)||6722K|
|Medium gray (50 IRE)||6702K|
|Low gray (30 IRE)||6533K|
Sadly, green was a little strong, enough, that it needs some correction. Otherwise, that is a superb set of readings.
By selecting User 1, instead of Cinema, then selecting Cinema as the starting point (all on the first menu), with minor adjustment, the end result proved to be a truly excellent set of numbers, and corresponding color accuracy for movie watching:
Comment doing the calibration based on Cinema 1, doesn’t seem to give exactly the same balance to start, as Cinema, (more blue in user 1), but overall, made the calibration a snap.
Gain R50, G49, B45, Bias, R48, G48, B46
|White (100 IRE)||6610K|
|Light gray (80 IRE)||6619K|
|Medium gray (50 IRE)||6599K|
|Low gray (30 IRE||6313K|
With these settings the noticeable green shift, is gone!
Dynamic, Lamp Hi, Iris 19, Color Temp Cool (default) provided an image too blue
|White (100 IRE)||9184K|
|Light gray (80 IRE)||9141K|
|Medium gray (50 IRE)||9028K|
|Low gray (30 IRE)||9265K|
Better to just change Dynamic’s Color Temp to Normal for performance in the mid upper 7000K range – great for sports, etc.
|White (100 IRE)||7574K|
|Light gray (80 IRE||7589K|
|Medium gray (50 IRE)||7509K|
|Low gray (30 IRE)||7548K|
In Standard mode, I only measured white (100 IRE), which with color temp set to warm, was a very respectable 6636K. I expect that the color temp would have a similarly tight range.
Back to Dynamic. For maximum lumens, you need to switch the Color Temp to Native, which then gives you about 1200 lumens. Surprisingly, the measurements were still pretty good, in the 7500K – 8K range.
W5000 Image Noise
Ouch! This is the noisiest projector in terms of basic image noise, that I’ve reviewed for some time. DLP’s it seems, tend to have more noticeable image noise. I find the amount here to be borderline acceptable. With Brilliant Color turned off, the noise level is notably higher than the recent Epson – 3LCD, Sony – LCoS, and even the HD803 – DLP projectors.
It is enough that you might occasionally notice it without looking for it. You are most likely to spot it in bright blue skys, light gray and white clouds, and other larger fairly stationary parts of images.
Some say that image noise can make a movie look more “film-like” in that it is “sort of” like the grain in film. While it can be dismissed that way, I’m not buying. Less noise is better. I found that reducing the Clarity control setting for detail enhancement does help a very little.
There is actually a noise control feature (also in the Clarity Control sub-menu), but it is grayed out, according to BenQ, for sources higher than 480/576. Why? No idea! It says 2 (grayed out), but whether it is working at all, who knows. If it is, it isn’t doing a great job, that’s for sure.
Kick in Brilliant Color, and image noise becomes more noticeable. Not that you will care, watching a football game, but if you need Brilliant Color’s brightness for movie viewing, the noise is definitely there. Combine that with the other aspects of BenQ’s Brilliant Color implementation, and you have some image issues, that purists will not find it acceptable.
