Is it true 4k or faux 4k? for this price it must be pixel shifting faux 4k.

correct, true 4k on projectors nowhere near this price point

Cheapest native 4k projectors new are about 5 grand and up, with Sony being the entry point there I believe.

There's really extremely little sharpness difference between the DLP 1080p x 4 pixel shifted 4k projectors and those native 4k projectors though at normal seating distance. You would only start to notice a difference very up close in sharpness between the 2.

Having seen a lot of the different technologies for resolution being implemented I'd say this:

- 1080p is 1080p, there used to be a time not that long ago where this was a great improvement over all the 720p projectors out there. I've got a Benq HT2050 1080p projector in my basement theatre and it's served me so well for years now at 120" at about 12 feet seating distance and throws out 2.07 million pixels...I will say though:

- Epson 1080p x 2 pixel shift for 4.15 million pixels (they call it "4k enhancement", it's not 4k due to being half the pixels required though), is a noticeable improvement sharpness wise over native 1080p non pixel shifted projectors, you can absolutely see the improvement sharpness wise, but then...

- All the DLP 1080p x 4 pixel shift (.47") projectors including the 1528p x 2 pixel shift projectors (.66") that throw out a true 8.3 million pixels for 4k resolution are a smaller step up from the Epson units sharpness wise than Epson vs. 1080p but an even MORE noticeable bump up in sharpness from the native 1080p units than the Epsons are. These things are very very sharp when you look at native 1080p and them in a similar situation. Especially on larger screens or if you sit closer.

- Native 4k projectors like the Sonys and JVC send out the same 8.3 million pixels as the pixel shifters above I mentioned, but natively. I honestly have a very hard time noticing any real difference in real world settings (normal seating distance) in the sharpness between these and the pixel shifters that also throw out 8.3 million pixels. The pixel shifters do an excellent job into "fooling" you into believing it's a native 4k image fro ma sharpness perspective. If you get up close, you can notice a difference in the "fine print" if you will, but again, in normal conditions you just wont notice much a difference. Now obviously those Sony and JVC units are on another level with things like contrast, black levels, color, etc...over these $1000-$3000 pixel shift projectors, and that's why they cost 5 grand and up.

Pixel shifting is an amazing technology. You get basically the same picture quality for a fraction of the price.

Strongly suggest you call the company to find out how much it costs to buy a replacement bulb.

I have a Optoma HD141X Projector. It's a lower model than this one. My 1st bulb blew after about 50 hours (supposed to last 5,000 hours). We only use the projector once a week to watch one movie. They 'only' charged me 1/2 price and that was over $100 with tax and shipping.

Second one blew after about 350 hours. Better but no where near the claimed time. And when I say 'blew' I meant it! It literally shattered inside the projector with a loud POP! Had to shake the broken glass out. Crazy but from what I hear it is not uncommon with projectors.

For this new bulb I was charged full price which was about $200.

They also really encourage you to buy their brand bulbs. There is no where else to buy them other than from the company directly. It might be the printer ink business model. in other words, they make most profits from selling the bulbs.

Anyone else is selling off brand bulbs which the company warns might have less light or 'off' colors. Even so, I bought a bulb that fits from eBay. Despite the picture and description being on-point, they sent me a completely different bulb that I had to return. So it's a crapshoot. Will try again with eBay but it's not straight forward.

I think people that trounce on pixel shifters don't realize that they are in fact showing the required 8.3 million pixels every 1/60th of a second. At a normal viewing distance of 1' per 10" no normal human is going to be able to detect the difference between native 4k and these newer pixel shifters.

This excludes the Epson like you said. There is a noticeable difference between the 4.15m pixels the Epson throws up and the 8.3m the DLPs can do. Although, the Epson's usually have better contrast ratios which can assist in perceived sharpness and clarity. That kinda goes out the window if you're watching these with a lot of ambient light though. If that's the case then you'd probably want the sharpest and brightest projector.

Sounds like you might have a bad projector. I've seen other companies replacing the whole thing when bulbs go out this quickly. Good to know that Optoma doesn't look like one of those. A lot of people do get close to the rated hours, especially when Eco mode is utilized.

I agree. I have a 141x and the bulbs have both lasted well over 5000 hours. It could be an issue with overheating if no proper ventilation or the bulls are non OEM too. That said, I am looking to upgrade my 141x to a 4K projector that also has 3D technology.

Thanks for that info. I have an Epson HD 2040, I would like to upgrade at some point. So this is a 8.3m pixel so a HD x4, seems like the best compromise. I am in no hurry but will wait for a slickdeal. So if I see an Epson, Benq or Optoma for for less than $900 I should jump on it.

I own this projector. The biggest shortcoming I'd point out is the lack of HDMI-CEC or any sort of reasonable standby management. I haven't figured out a way to wake the projector from sleep from another remote or signal, and I've spent a lot of time trying to figure it out. The only mechanism that's worked for me is a Harmony hub with an IR blaster in view of the projector.

If I were buying now I would hold out for the Viewsonic PX-701-4K to ship and compare some reviews. At $200 cheaper with HDMI-CEC, if the quality is similar it would be the better choice -- The throw distance range and physical dimensions/lens placement are almost identical.

I put (faux) in the description for a reason. Even if it is faux 4k, I doubt many can tell the difference unless you are sitting three feet away from the screen.

I think you have a bad projector. I have an Optoma HD27E, similar to the 141x, for over a year now. I read about the bulb problem in many reviews so I bought a 3-year warranty for an additional $40, but so far everything is fine. Having said that, I recommend buying additional insurance if the price is right.

Have you heard any news about the Viewsonic release date? Been hearing the specs on this new projector are worth waiting for.

Linus from Linus Tech Tips just made a video about this projector. It's worth a watch if your interested in picking this up.
