Yes yes fake 4k but still decent price as most fake 4ks are £1k+. RS seem to be the lowest around for this model.

Viewsonic make some good projectors. Heat for a sub 1k 4k

Looks like a decent deal. Shame about the lack of 3D
very poor specs - lumen, contrast etc... i prefer to buy decent 1080p for half price
Interested in upgrading to a 4k projector at some point but need one with great lens shift. Struggling to find one. (Currently got a Benq W2000 which has been a really good buy) So, as an upgrade this one is no good for me.

Why fake? Still 4k resolution

Why fake? Still 4k resolution


Just means not native 4k. But to be honest to get a full 4k actual projector your looking at £3k+
I'm after the Acer m550.. near silent running and better input lag speed.
Viewed one of these today, it’s really good with 4K and at this money, it’s well worth it.
I have a basement room with gloss white walls. Would a projector work in this environment?

Thanks

You want matt walls
It says pixel resolution is 3840 x 2160 so that's 2K right? Does the 4K mentioned by you, albeit 'fake 4K', just mean it can play 4K files or sources in the same way my 720p projector can play 1080p files and sources?

A lot of good home theatre projectors are lower in lumens. They don't need to be as bright as data projectors - that may need to compete with other light sources. Lumens does not equate to quality. Contrast can make a different... But like early LCDs there is a lot of rubbish contrast specs going round. DLP is my only concern here. Will fatigue your eyes .
Can you elaborate on what you mean by "fake 4k"?

3840 X 2160 is 4k, or at least that's what the majority of people call it. 4k pixels wide.
Faux 4K projectors pixel shift to create a 4K image so that it does actually display 4K but does the pixel shifting so fast it’s undetectable to the human eye.

So if the projector accepts and displays a full 4k picture, the bit in the middle does not matter. It's 4k HDR certified...that's what you need to look for.

Also different projectors have different types chip, e.g. Optoma UHD60 is 1.5k so the alternating images do not have to double up. It's a neat solution.

Yes, I don't understand all this "faux" 4k stuff. The pixel shifting is done so quickly that the eye would interpret it as 4k.

Projectors with coloured wheels also simulate a full colour image by displaying red, green and blue images in succession. Apart from those sensitive to the rainbow effect, you don't get that many people calling it faux colour!
Would this be much of an upgrade from my HD142X? Looking at the specs this fairs worse in the contrast/brightness stats...
This is 4k resolution 4k is 3840 × 2160 people seem to get abit confused 8k is 7680 × 4320 remember it's the horizontal resolution not vertical eg 3840 is 4k and 7680 is 8k, 720p and 1080p are taken by vertical pixels instead so in theory you could class a 2k set as being 1080p because it has a resolution of 2048 X 1080, just think to yourself if the last letter is p it's vertical resolution if it's k it's horizontal resolution if you don't believe me just look it up

No, 3840 x 2160 is 4K. 2K is HD/FHD/Full HD/1920x1080. When it's written in terms of 'K' it goes by the number of horizontal pixels (I know, it's confusing, because otherwise we talk in terms of vertical pixels - 720p, 1080p, 1440p, 2160p, etc.).
Either way, it will display any kind of content and will just scale it accordingly (depending on what you're playing it from).

I thought fake 4K projectors (which I've heard referred to as 'Faux K') were the ones that used pixel shifting? This one doesn't appear to - the description states it "delivers 3840 x 2160 distinct pixels for true 8.3 million pixel 4K UHD resolution".

So what's fake about it?

It does use pixel shifting. The distinct pixels are the ones within the projected image.

You're right, it does, but I had to do some digging to find it mentioned in some reviews.

I'd say it's a decent upgrade but then it's twice the price. Projectors seem to hold their value well (if you get a good brand one) so holding out for the prices to drop probably will take a while.
This is a quad pixel shifting 1080p .47inch TI DLP chip projector. it achieves the 4k resolution by quad pixel shifting so fast your eyes can't perceive what is being done to generate the full 4k resolution. Some people call double and quad pixel shifting faux-k as a joke on native 4k. Native 4k often uses a single chip in the case of DLP with colour wheel or in some cases 3 chips if its one per colour with a resolution of 4k on each chip. The faux argument suggest that your not getting 4k and that some trickery is used such that the image will be inferior from a sharpness point of view, this is not the case. You are getting a full 4k resolution and this is state of the art tech to reduce costs not image sharpness. Now you can reasonably argue that higher priced native 4k projectors have better image quality but that's not down to resolution it is better contrast ratios and other factors. Indeed in objective tests faux-k projectors often have a higher perceived resolution than native 4k projectors at very short viewing distances. This again is irrelevant for the most part as people don't sit right next to screens to see the individual pixels. This is an amazing break through price for a 4k projector faux or not.
if your want higher brightness the PX747 is available for £75 more technoworld.com/vie…BwE - the only difference i'm aware of is the brighness is increased to 3500lm as it uses a different colour wheel inside.

Just a note as to where faux 4k first started being bandied about. It was from early days of 4k when 4k images were accepted by e.g. projectors, but the display was 1080p
remember the input latency for this model is around 50ms if youre thinking about gaming on it.

I use the workhorse 1080p model the Benq w1070 and I think that is the thing thats holding me back. 20ms vs 50ms will be quite noticeable (desktop monitor I use for competative gaming is 3-5ms)

Although a lot of games on consoles dont really rely on good reaction times some will definitely test your patience. Fighting game combo links will need delaying or pre input, dark souls or bloodborne parry timing will be off, rythm games like thumper will infuriate and games like doom will feel a bit floaty in turning.

I was going to give this a miss as I already have a optima 1080p projector that’s about 3 years old. I’ve had projectors for the last 20 years or so including the old crt style barco models that where massive so gone through probably a dozen over that space of time. However at just 899 I couldn't resist and picked one up a few days back. I’m amazed at how prices of this tech have dropped over the last 5 years or so. A 4K projector for under a grand was unthinkable just 12 months ago. I’m so pleased I went for this as it’s a real step up from my older optima model. If your getting a projector and have 4K content and can stretch to this or any of the similarly low priced 4K projectors on the market it’s a great time to buy.
