Which one? The 727 has ~500:1 native and ~1200:1 dynamic and 747 has ~370:1 native and ~750:1 dynamic.

The HC3800 has ~1700-2000:1 native and ~35 000:1 dynamic.
The HC3200 has ~450:1 native and not sure about dynamic. It does have an active iris which helps.


Something that can cause irregular focus is the projector not being perpendicular to the screen. If screens are just mounted to walls it may not straight, since walls are often not straight.

HC3200 has 40 000:1 dynamic, and is OK but not impressive by any means. I haven't seen the native contrast ratios, I guess I'll have to dig more for that info.

The projector is perpendicular to the screen. The difference in focus requires moving the particular corner multiple feet closer to the projector to rectify (tested with a sheet of paper walked closer, and I can guarantee you my wall/screen are not _that_ uneven.

Flipping the projector (ceiling mount vs tabletop) results in the blurry section moving to the opposite quadrant, which is also proof it isn't the wall.

I'm no pro, but it sure sounds like a defective or damaged unit to me. There's no way having that much area be so out of focus (multiple feet) be acceptable for a properly functioning device, assuming no environmental or installation flaws.

Ouchers on that 3200s native contrast

450 vs 1700-2000 is a big difference in true native contrast... where is the source for that data?

The irises are probably the same

Also sounds like each respective tier has lesser and lesser defects
IE 3200<3800<4010<5040<5050

If your focus is that far off though like it takes multiple feet, I'd return it

My focus on my 3800 isn't perfect but it was equal to the DLPs in its class
When I say not perfect, I can't get the focus razor sharp, not like it is physically out of focus
In no area can I not resolve individual pixels on the screen in other words

The best test is to bring a friend over and have them look at it.
If they can see wrong stuff, yeah your machine is broke.

If not, you may have projectoritis; a mild form of OCD contracted from owning a projector. This is remedied by spending more money.

LOL Projectoritis - most people on this form have mild-severe symptoms of that.

Are the 3800 black levels significantly better than the DLP units? what about Mixed scenes (Mid-High APL)?

I'm certain the HC3200 does not have 40 000:1 dynamic. I assume that you're taking that figure from Epson's specification. Which are not true (contrast).
The HC3800's contrast claimed by Epson is 100 000:1, which is obviously not true.

Those scenes will have an advantage with DLP, at least on paper. IRL the difference is not that big, with the room hampering whatever advantage DLP might have. Even in a treated room the difference is not significant IMO, and noticeable. However poor black level in low ADL scenes will be noticeable.

Hi,

I've had issues with uniform focus as well and played around with placement for a while.

This is a snippet from my 3800 review on Amazon (You can go there for my full review, I have the picture of my Panel Alignment pattern there, sorry I can't find the original at the moment to post here).

"Update: As some have commented on inability to focus across the entire screen. I had to work on the projector position a bit as I had a similar experience, but after I pointed the projector "slightly up" (still no keystoning), and used lens shift to bring the image down I was able to get a completely uniform focus at all sections of the screen. I added a picture of the Panel Alignment pattern to show it is sharp on all locations of the screen (the missing lines are due to my black velvet screen masking). Maybe I got lucky with mine but I've had no issues with focus or blurring after adjusting."

Is that ceiling mount or tabletop? I think you got lucky. I've been through three of them, all easily reproducible. A major Epson benefit is the flexible placement, and if you have to stand just so with it to get it to work, that benefit is nullified.

Projectoritis definitely...funny...I'm certainly looking at the spending more solution.

I've tried ceiling, low table, and I'm currently doing high table floating-shelf style mount

The third is best for me at this point because it's less precarious and prone to vibration than the hanging (underneath my furnace unfortunately) so I have mine on a floating shelf.

Image uniformity was best with the low table style mount... IE just over your couch or on a table or shelf
When I hung mine, I used an extended ceiling mount which also did bring the PJ closer to center, just more upside down.

Mostau might be right about pointing the projector slightly up too, my setup is actually slightly inclined, though I'm using a lot more lens shift to bring down the high shelf upright style mounting.

Also, btw for those who might have been curious the list of official accessories is at this link

https://files.support.epson.com/doci...3200_3800.html

That has the part #s for filters, lamps, the official mount that's supposed to go on this, etc.
There's even some wifi chip but it looks limited

I've got a 3800 and focus uniformity is not much of an issue, I get pretty good clarity on a 150" screen.

Ceiling mounted about a 1.4x zoom.

Epson HC 3200 and 3800 revealed

The 3800 has been nothing short of amazing for me. I will never go back to regular TV!

I am ceiling mounted, however I have a vaulted ceiling and I've lowered the projector 16" so it is a tad below the top of the screen (maybe 1 foot down a 6 foot tall screen) so I have some headroom to point the projector up. You view can my setup here (scroll down past the video zoom screen shots for the room setup, or up a tad to see the projector mount)...

Unfortunately I deleted my original picture of the alignment pattern after I uploaded it to Amazon. I grabbed it back from there but it is lower resolution than the original. I'll try to take another this weekend (after the sun is down).

Update: I took a new full resolution picture of my panel alignment pattern. Have a look.
