I've had both for two weeks. The 5040UB has some enhancement modes, and a color alignment feature that most people don't know about or explore.

As for the Optoma UHD65, it too has an alignment feature and some pixel enhancement.
Hi, Bob. What was the alignment feature for the UHD65? Was it for layering the pixels or something like that....wondering because it's single chip.

As I remember, it has a Color Management System (CMS). You select the color and there is a grid wherein you adjust the x and y of the color. You can also adjust the brightness. The 5040 has a similar feature to align the 3 LCD colors. You can download the UHD65 manual and see it described, although, they don't include a working example.

For some reason, unlike JVC, Epson does not seem to reach the ~3K potential or gain any real detail by shifting its native 2K panel. Not sure if it's Epson's algorithm, lens, alignment, or some combination of these - JVC does much better with the same resolution panel.

The Optoma UHD65 looks extremely sharp with 4K content, similar to Sony's 4K projectors. The lens uniformity may not be perfect in all samples with some brightness falloff at corners, but that will vary from unit to unit.

The 5040UB is so soft, I'd say even a cheap 1080p DLP like the BenQ HT2050 is sharper.
I know this was posted a while ago, but I just went from a 2050 to the 5040UB and can say that the 5040 has a much sharper feel to it. Not as sharp as my friend's UHD65 but I can't see any actual pixels from my normal viewing distance. Just my two cents.

The Epson's vary in sharpness according to how good of convergence you received (your particular sample), however they are generally as sharp as some of the cheaper DLP's, but not all.
The Viewsonics are (from the reviews) a bit sharper, then the Optomas are next, then the Benq's. Some of the Benqs are the least sharp of the cheaper DLP's, but depends on the Benq model.

The problem is it is somewhat of an Apple to Oranges comparison, you are comparing an LCD with a wider pixel gap to a 4k DLP with a lesser pixel gap.
I suppose it might be more fair with the Epson's e-shift engaged, but given the Epson's e-shift algorithm has imperfections, still hard to judge.
