Anyways I am coming from pf1500, do you think 4k XPR would be upgrade to it? not really sure how the XPR thingy works and how it affects the resolution, I am assuming it does some fast pixel shifting, so pixels are still 1080, but just shifted at high speed to cause an impression of getting 4k? maybe i don't get how the technology works for XPR, any help would be appreciated.
In my experience, having spent time with the BenQ HT5550, BenQ HT9060, Optoma UHZ65, Epson 5040UB, Sony 295ES and JVC RS540, I would rank them on 4K detail and resolution (ONLY) from worst to best as follows:
6. 5040UB (mediocre 3xLCD 1080p Pixel Shifting, mediocre lens, color bleed and enlightenment issues, screen door effect)
5. BenQ HT5550 (0.47" DMD 1080 x4 shifting XPR, decent lens, color wheel)
4. JVC RS540/x790 (good 3xLCD 1080p pixel shifting, decent lens)
3. UHZ65 (0.66" DMD 2x 2716x1528, mediocre lens, color wheel)
2. 295ES (native 4K 3xLCD, decent lens, chroma bleed and alignment issues)
1. HT9060 (0.66" DMD 2x 2716x1528, excellent lens, no color wheel)
Basically, in my opinion, a single 0.47" DLP chip will be sharper than the 1080p 3xLCD because of the alignment issues and color bleed associated with 3LCD. Will 0.47" DLP XPR 4K be an upgrade for your 1080p LED projector? well, a bit, but it's only really worth it if you are adding better contrast and light output as well, otherwise it won't make that big of a difference.
However, if you upgrade to a 0.66" single chip, I believe it can almost match a native 4K 3LCD for sharpness even with a mediocre lens, and can actually beat it when paired with excellent lens optics and no color wheel. This is because of the convergence issues associated with 3 chips vs 1 chip. The BenQ HT9060 with its large single chip XPR, no color wheel, and excellent optics can actually beat the native 4K on the Sony 295ES. Again, this is for resolving 4K resolution only.
Contrast and perceived detail is another matter... in that case, the JVC RS540 and Sony 295ES can give a more compelling image in a dark room given their higher native contrasts.
I don't know what your budget is, but if you are not sensitive to rainbows, I think that the UHZ65 is best combination of 4K detail and contrast implementation, along with good color and brightness uniformity over the life of the projector, all for good price when compared to other lasr or native 4k projectors. If that's too expensive, then the BenQ HT5550 is about 1000 less and is still very good, but its 0.47".
If you are sensitive to rainbows and want the best resolution and contrast, then Sony 295ES is the winner for me, but the JVC RS540 is a better all round package with slightly less resolved 4K detail, but better contrast, a iris and lens memory. I can't recommend the Epson projectors, I just don't like the look of translucent LCD.
The absolute sharpest 4K image you can get will come out of a 4K XPR 0.66" DMD with excellent optics and no color wheel, such as with the LED based BenQT9060/9050. Contrast isn't great, but they actually beat native 3LCD 4K projectors like the Sony 295ES for resolving 4K detail IMO. This video shows what I'm talking about
Those projectors are probably best for sports and video games in a family rooms with some ambient light setup with an ALR screen. The black levels are unacceptable to some, but for me who is extremely sensitive to rainbows yet hates the 3LCD alignment issues, it's a possible solution. Its too bloody expensive tho lol
