Epson 810 HQV Calibration & Measurements
The PowerLite Pro Cinema 810 HQV projector seemed to lack some of the more saturated greens (according to the CIE chart, however this wasn't apparent in our viewing tests and we were using a DVD source for our measurements which is less reliable than a calibrated video signal generator.
We again utilized datacolor’s ColorFacts Professional 6.0 software to calibrate and measure the grayscale response of the Epson projector. The PowerLite Pro Cinema 810 HQV is an exceptional projector that comes with pretty good performance out of the box, except for some oddities. For example, when setting White levels you must have Epson Super White 'On' in order to get whiter than white output from the projector. On the other hand, I could not initially seem to get the 810 HQV to pass 'blacker-than-black' with HDMI. Take away the TX3 Silicon Optix processor and the pattern showed blacker than black. Taking the next step I quickly realized that I'd need to make adjustments in the TX3 and raise the black level to get to the point where I could see the 'blacker-than-black' bars I was looking for. What I ended up with was Brightness = 55 and Contrast = 49 (defaults are 50 and the Epson 810's settings were at 0):
While calibrating the Epson I noticed two things: One, the remote control could be pointed almost anywhere and still control the projector, and Two, Epson makes you take about a dozen button presses to get back to the RGB Gain/Offset menu. By the time I was done I had engaged hundreds of button pushes - no exaggeration. Remembering the last menu function would be a really great improvement for more casual users.

While the projector looked pretty good, it was obvious that even in Cinema Night mode, the color would need to be adjusted. |
We dialed in RBG pretty accurately and there didn't seem to be any "rubber band" effect that we see so often on projectors these days. |

Color temperature looked acceptable and of course could be dialed in further by the system. |
After calibration we had an almost identical temperature histogram. |

Color temperature was close, but we found that we could do a bit better. |
Once tweaked, the color temp stayed fairly even at 6500K - right where we wanted it. |

New to this site, so I hope someone can help me. I just had installed the Epson Powerlite Homecinema 1080p. I already had a curved, 4:3 ,100" diagonal screen that was installed some years ago. The installer told me that this projector would work best with a flat screen rather than a curved one. Is this true? Are there anysettings that would adjust for the fact that the screen is curved?
Also, how can I change the aspect ratio to 4:3. Is this done through the settings menu?
Does this projector have a keystone correction?
Thanks

First, does using the HQV processor yield a 1080P pix on the 810 projector even though the projector isn't rated at 1080P?
Second, you gave the 810 HQV a score of 125 and an excellent rating, but the 1080P got a score of 85 and failed most all of the film detail tests. Does this mean that, although the 810 HQV can't display 1080P it delivers a far superior picture compared to the 1080P?
Conversely, although the 1080P can display 1080P natively, it's picture quality is far worse than the 810 HQV combo?
I'm new at this so please excuse how dumb it may sound!
Thanks
I figure he meant the 810 but i guess i want to be sure!
