This is a good benchmark for those looking at convergence issues.

This is a picture of unacceptable convergence on a 1080ub projector. If your convergence looks like this or worse, I would recommend a replacement.

NOTE: this is border line...it is 1 pixel off an almost all colors and is more than one pixel on some. (noticable from normal viewing 10ft)


Any less than this...epson will not replace. (you shouldnt see it from normal viewing anyways)

ALSO...It looks a lot worse in pictures than it was in real life...remember this is a 3 or 4 pixel white line. My camera is zoomed way in.

those of you looking for this pattern...just type "convergence test" into google




Honestly...in my opinion...the best convergence test is to bring up the menu for the 6500ub where you are sitting and if you can see a distracting amount of color on either side of the white menu text from your normal viewing distance...you have a convergence issue that should be addressed.

Please keep this in mind when you are running that convergence test pattern and have your nose 3" from the screen.

^^ +1. I feel that if you can see the misalignment about 1 feet from the screen it is unacceptable. LCD panels are not perfect and you will rarely get a pj that has zero convergence issues. but if you see more than one pixel off, get it replaced.

You guys are a pro . Good description on what to look for.

Here is what perfect convergence should look like:



Here is what miscovergence looks like:



The second pic shows green off by about two pixels on the left of the letters and one pixel red below and one blue above.

Use the menu on your pj and look at the words. Perfect, or near perfect would yield a white dot (pixel). Misalignment would yield a red, green or blue dot either to the left, right up or down from the white dot. One dot shift = one pixel off, two dots = two pixels off, etc. Epson states one pixel off is standard.

I experienced something that I initially thought was a convergence problem. I'm using maximum vertical lens shift on my ceiling mount (10' ceiling) and I"m getting a magenta/purple colour that I would describe as a "smudge" that is several pixels deep on the menu borders and on B&W test patterns. The pixels also look a bit fuzzy. It's worse at the bottom of the screen and dissipates near the top. It appears to be a mechanical lens/distortion issue rather than convergence according to a calibration expert at CalMan that I spoke to. My convergence looks quite good. I'm waiting for a call back from another tech person at Epson to discuss. I can't say that I notice a sharpness issue or any noticeable aberrations on HD material though.
I'm going to try projecting in the normal position and with reduced lens shift to see if it goes away. If it does, I may need to modify my mounting, unless Epson says it should be replaced.

How far should I stand to determine it?

^^ If you can see it from your first row of seats (or normal seating position), that is a problem. Others feel if you can't see it from where you sit, you are ok. I am a little anal. If I can see it from one feet away and not from my first row of seats- which is about 11 feet away, I am not satisfied. I know it is there and it will bother me.

Sounds like what you are experiencing is called "chromatic abberation." This purple fringing is caused by failure of the lens to focus all colors at the same point. Your extreme vertical lens shift is probably what is causing this problem. If you did not have this problem before the lens shift then that is it.
post #2949 of 4366
What I find really nice about having issues with this projector is that if I am fine with a convergence issue now, but 6 months from now I want it replaced, Epson will still send me a projector overnight (assuming they have stock). I took some pictures and it appears 1 blue to the left and maybe 2 green to the right. I am hard pressed to see it from about 2 feet, any closer and I can notice it.

I vote for CA as well.

Most projectors start having "issues" when you get the lens to its full adjustment in either direction... you are no longer taking advantage of the "sweet" spot in the lens and these lenses are not large enough or perfect enough to perform at the extremes.

Ya, I think you guy's are right. Before mounting the projector I let it burn in awhile and projected the menu on a wall looking closely for signs of convergence and listening for noise. While the image was much smaller than the installed image, I 'm sure I would have noticed this. This was however, with minimal shift and not inverted. I'll try experimenting with less lens shift.

Does anybody use a harmony remote with this projector?

I am thinking about the harmony 1100 .

I feel that with this update the Epson is a "gem of a projector."

Are we to assume that 4:4 is ON or OFF with Art's recommendations?

Hey Guys:

My serial Number is LGYF910018L

Has the defocus issue been corrected on this serial number?
post #2955 of 4366
I use a Harmony 1000i and it works with the EPSON with no problems at all.

I am even able to shut the PJ down with the one press of the system OFF button, which switches all the components off at once.

Thanks for the confirmation. The 1000i is the US version 1000. All in the same family so it should work with the 1100 .

Are there any discrete codes to toggle between FI off, normal and high to work with the Harmony remotes?
post #2958 of 4366
I have received my replacement unit this week with the 1.09 firmware.

I have randomly experienced frequent flickering of the screen upon start up. The flickering happens when I am watching tv/blu ray. The flickering includes lines of all types going up and down the image too.

The solve the problem, I have to turn off the projector and turn on until it goes away.

I am a little disappointed now.

What order do you guys turn on your devices?

The only way to find out is to contact Epson. I was told from Epson that the >2000 thing was false.

I am placing this PJ on my short list and was wondering if a 10 1/2 ft placement from a 104 inch screen is possible. ( adequate lens shift )

I have my Universal Remote MX3000 set up this way: projector, then receiver then panasonic bd30 blu ray player. I would contact Epson and request another projector. That doesn't sound right.

If you are talking about a 104 inch diagonal size screen with a 16 x 9 aspect ratio then the answer is YES but it would require the Epson's lens to be set to virtually its widest zoom setting with a projector to screen distance of 10 1/2 feet. Also when you say "10 1/2 ft. placement" my answer assumes that the distance from the front of the projector's lens to the screen is 10 1/2 ft. I don't know what to make of you statement "adequate lens shift" since the term lens shift is a feature to allow the projector to be placed at locations that are not centered with the screen and is different from zoom function which allows you to make the projected image larger or smaller at a given distance from the screen. The Epson does have both vertical and horizontal lens shift as well as zoom functions.

I don't believe the Epson has a discrete code for this (I'm using a Harmony 880 with my 6500UB).

I guess I just have to try adding a sequence for each command.
post #2965 of 4366
Yes, that would be the distance from the screen to the PJ lens. My current setup is roughly 11 ft and is centered to the screen. I was looking at moving the pj in about 6 inches so it would be placed more overhead of the front seats. My current setup has the back part of the PJ in front of the back row seating and would like to move it ahead to allow more headroom in front of the back seats. The PJ I have now is the

Dave_1,
Epson has a calculator on their website that will calculate this. According to a 126" throw distance the maximum screen size diagonally is 107" for the 6500 UB.

Though I am not 100% sure of this, one thing you can check is to see if the pixel offset is reversed from one side of the screen to the other. That is to say if you see that if you project the white line pattern on the screen and see that one of the colors is shifted left on one side of the screen and right on the other, it is probably the lens or the projector is aimed at an angle to the screen. My thoughts on this is that if it is a panel misalignment, that the specific panel should be shifted in the same direction on both sides of the screen. Thoughts?

The problem is that it doesn't happen all the time

At this point, I am really seriously doubt I can get a "perfect" one from Epson.

For the people who gotten 2nd or 3rd replacements, are you guys getting new projector or refurbished?

I bought mine and called in to get a replacement before my 30 days. Waited a month and they send me a new one. Tomorow will be 1 week since I got the replacement.

I've been through two replacements, both were brand new.
post #2970 of 4366
well, I'm on my fourth unit and perhaps the last.

Unit one- Frozen focus ring
Unit two- two dead pixels, loud iris
Unit three- dust blob, loud iris, defocusing
Unit four- video freezes up for no reason, 5 minutes into viewing (just received today ver.1.09)

wow...
