BenQ HT1075 Projector Review - Performance

Brightness is measured with zoom at mid-point.  When comparing to the brightness of projectors done prior to 2014, including the older BenQ W1500, and W0170, metering equipment and calibration software have changed.  Current equipment measures approximately 10% brighter than Mike's older setup.

As you can see from the table, Bright mode is the coolest, but it's more notable for its strong green and yellows than the cooler overall temp.

All the other modes offered up very good grayscale.

Note that Eco mode measured approximately 37% lower, which is surprising as Optoma actually states that eco mode is 30% less bright.

User 1 (and User 2, not shown), have the same measurements, and those are pre-calibration.  Note please, that the measurements are essentially identical (well within the margin of measuring error) of the measurements for the Standard mode.

User modes, like Standard, are slightly thin on reds.

Not much to see in this table.  We don't report as many IRE points on pre-calibration data, as we do on post, but from the four points from white to medium dark gray, they all measure very close to each other - in fact within 50K, which is very tight.  (There is more shift in the much darker regions).

If the overall color temp for these brightness levels were just 200K lower, they would be close to perfect, at least as far as grayscale balance goes, and they would put back in that little bit of missing reds.

Between Standard mode, and Cinema mode, the brightnesses measured within 2% of each other.

Without adjustment, Cinema will, for most critical viewers,  be the preferred mode compared to Standard, but both are very good. Standard seems to have a touch more punch, so for something like sports with some ambient light present, you may favor Standard.

Even our calibration settings, found in the calibration pages, result in only minor adjustments compared to the default.

Only Bright mode has color balance issues that are of significance.  Figure to use Bright only when you are fighting a lot of ambient light, because the Bright mode with its strong yellow-greens is not very pretty, but it will get the job done when every last lumen is needed!

From White to dark gray (20 IRE), the HT1075 produces a very tight, color temp range, varying by less than 150K!  That's about as good as the numbers get.  More to the point, the balance between red, green and blue is excellent.  The only range with enough deviation to mention would be white (100 IRE, which is still just a tad thin on reds, and a tad strong on greens, and 20 IRE - as far down as we measure, where there's just slightly too much blue.

But I'm really quibbling.  All considered few projectors at several times the price would calibrate any better.
