Epson LCD FP 6020UB – Calibration Notes

[Anonymous]

I calibrate this projector couple days ago. I checked several modes but THX was the best to start with.
I calibrated it for 1080i/60 and 1080p/24.
I started with 1080i. There is only two point grayscale calibration but it was fine. After calibration delta E under 2%
I was able to calibrate Color gamut to perfection with errors under 1% for all six colors.
Final picture was great. No green tint like on 8350 or some other Epson projectors.
Black level is high. (StudioTek 130) This projector needs dark screen to improve black level.

What amazed me a lot it is multi point convergence alignment.
How is it possible on LCD panels? I understand how CRT works but LCD?
Can anyone explain it to me? Do they somehow bend LCD panels?

Did you guys read “We Three Projectors” By Geoffrey Morrison in Sound and Vision magazine?
What is a point to publish calibration report with so bad final results? http://www.soundandvisionmag.com/article/we-three-projectors?page=0,2
Contrast is too high. Gamma under 1.5 for 90? Gamut luminance not corrected?
Is really 5020 so much worse than 6020? (I didn’t calibrate 5020)

Multipoint on the Epson and the JVC is something you should not use. It is a localized version of digital keystone. It will reduce resolution and introduce moire effects to the region that you work on.

The most visible problem I saw after using Epson’s multi-point alignment (I forget how many points can be adjusted… more than 128 if I recall correctly) was that after aligning the entire screen to be perfect, when you displayed anything full-screen that wasn’t too dark (say from 15% or 20% white and brighter), an oval in the center of the screen had a visible green tint and the areas under and above the oval had a magenta tint. That wasn’t there before using the multi-point alignment. Full-screen single pixel black/while alternating line patterns did not seem to suffer from using the multi-point alignment (no apparent localized moire or loss of resolution), but it could certainly happen… perhaps I didn’t have to make moves large enough for it to become apparent. The green/magenta discoloration was fairly distracting and not difficult to see, yet I wouldn’t call it huge either. The problem I had with the 6020 was that the factory alignment was imperfect enough that at my normal viewing distance you could see red fringes from the alignment not being perfect fairly easy. There were also some visible blue misalignments but those were harder to see from the main seat than the red misalignments (not surprising). I didn’t think Epson’s optical system was very good either. No matter what you do, the images have a soft look to them… not de-focused as much as being softened by internal reflections in the optical system (including the lens).

Do you know how they do this? I am just curious.
Picture was fuzzy before alignment but I found that after four corners calibration alignment was fine and multipoint was not required.
I played a little but just because I was curious how it works.

I expect it is just a more complex break down of the digital keystone. Whether you distort the whole image or just part of it …

Do these have a ISF unlock code?

Aside from it being a niceity … the ISF locks really are not necessary on this projector. It has 8-10 memory positions. Save the calibrated work in all the slots. Hard to “accidentally” erase the settings in all 10 slots.

I saw one in a show room. I was informed it was setup up properly (alignment and focus) but like what Doug witnessed the picture seemed on the soft side (with Bluray). I am wondering if this is the consensus with this unit.

Being informed that it was set up correctly does not mean it is. 🙂 What are they going to say? It is not set up properly? 🙂

In the epsons I’ve seen, I would say it looks similar to last year … not much different when set up right.
