Panasonic PT-AE8000 Projector – Performance 2

There is a measured roughly 14% increase in brightness if you place the PT-AE8000U at its closest position to the screen, in terms of zoom (wide-angle), compared to having the zoom at mid-point, with the projector 50% further back.

At full telephoto the PT-AE8000 is about 40% less bright compared to wide angle!  That means you are reducing this projector from very bright to about average brightness if you rear shelf mount at the full telephoto range.

Changing lamp mode from full power to eco mode should result in the same amount of brightness drop, regardless of color mode. In this case Mike used both Cinema 1 and also Dynamic to confirm his measurments. The 643 lumens measured in Cinema 1 dropped to 402 lumens in Eco-mode. That’s an unusually large, about 40% drop in brightness (essentially the same percentage drop that the PT-AE7000 showed last year.  Dynamic dropped slightly more, but that within our measuring margin of error.  It dropped from 1898 to 1034 A drop of 40% is more than most projector’s eco modes deliver.  I’d say more typical of low power modes are drops of 20% to 30%.

Those numbers are very good for right out of the box.

In addition to the RGB settings, Mike adjusted the the Gamma settings and the basic controls (Brightness, Sharpness, Contrast…) Those are all reported on the Calibration page. If you aren’t having your PT-AE8000 calibrated, you might try ours.

Mike has written up a good deal about his findings when calibrating the projector. You will find that on the Calibration page as well.

For now, however, a useful excerpt:

Mike’s comments:  Overall, the projector looks really good.  Grayscale is not bad right out of the box, though there’s too much blue and too little red in Rec. 709 mode.  It calibrates fairly well (see graph), but the color temp and RGB balance are not as flat as I’d like to see (note the peaks of red at 40 and 50 IRE in the RGB Color Balance chart and the bumps in the Correlated Color Temperature chart.  None of this is really visible in actual use however.
