When will 4k projectors become affordable?

[bigboss]

Seen the WHF article on the LG "W" TVs?

If they made one of those at (for me) 110, maybe 120 inch diagonal 16:9 (I'd prefer CinemaScope, but...) , price around $10k, I would have no need for a 4K PJ and screen at all. Easier to install, no cables to run through ceilings, no need to paint the movie room black, no bulbs to replace....

Perhaps that's where the home "big screen" market is going to go.

A 120-inch TV will be extremely imposing, besides have a very small market (most houses won't be able to accommodate that, will be impossible to get them into upper floor apartments etc.). Also, direct light from such a large TV won't be good for the eyes in the long term.

PS you sound like my granny

" don't sit too close, it'll send you blind!".

I'm not going g to sit there watching the bloody thing 18 hours a day, and I'm far more worried about the 8 to 10 hours a day I spend with my head 18 inches from my PC monitor....

The World does not end at Dover! Many many many homes in the US could easily accommodate such a TV. Not to mention all the sports bars, clubs, schools even. Yes, the market will be smaller than for a "regular" 60 in her, but then the prices will be 10 times as much, not four as screen size ratio would suggest.

120 inches at 16:9 works out at roughly 8'10" x 4'11" if my sums are correct.

That would fill the gap between the in wall speakers in my not at all exceptional for the US 12'6" wide HT room quite nicely. And yes, we could get it up the stairs too. Well, three of us could

BB had points you have missed

120" tv and 4000 nits peak brightness hdr image is going to be bright. They could probably play college football in your back garden but only on in the peak highlights lol

Where does power consumption limitations start to kick in. I know tvs now use less but they are half this size generally

 

[bigboss]

TVs in current format will not succeed at those sizes. The market will be very small. Yes the world doesn't end in Dover, but the world outside Dover will be very small in the grand scheme of things (when you compare with the world's biggest markets for TVs).

Wallpaper TVs and window pane TVs aren't far from reality......They're more likely to succeed in such large sizes.

 

[Benedict_Arnold]

4000 nits peak brightness hdr image is going to be bright.

One presumes the number of nits need be not much greater than those of a 4K PJ image, although many say a brighter PJ image would be desirable anyway. I can't do lumens to nits conversions sitting here in my jim-jams, but I see no reason why anyone should assume that a large TV need put out the same sort of light intensity as the Fastnet lighthouse...

One presumes that if you can afford a 120 inch 4K TV you can afford the electricity to run it. FWIW our electric bill is dominated far more by the air conditioning costs, $300 to $400 a month in Summer, than by gadget use.

The UK's 13 amp socket was originally specified to run a two or three bar electric fire (3kW), and can safely deliver over 2.5 kVA (about 11 amps @ 240 volts). A US 110 volt, 15 amp socket, about 1500 watts. The latest LG signature 77 inch OLED consumes less than 300 watts, so there's plenty of headroom yet.

And yes, a 120 inch TV will fit through a standard doorway. If you can get a king-size mattress up the stairs....

Ellisdj alludes to the strict Government norms regarding electricity consumption by TVs.

 

[Benedict_Arnold]

Once you're free of the Brussels yoke you'll be free to use electricity as you please again. Hopefully.

 

[ellisdj]

I was thinking by the time tvs that big are out 4000 nits will be the norm / expected so no way of avoiding it.

BB is right i was thinking there must be a limit to how much juice device can consume but I didnt know for sure.

 

[Benedict_Arnold]

About 2500 kVA is safe on a standard 13 amp plug.

That's about seven or eight 77 inch OLEDs.

Anyway, I checked my measurements and I can "only" fit in a 110 inch because of the in wall speakers already fitted and the wall studs that dictated their locations. How disappointing....

That's another advantage of projector over large TV...... Flexibility in screen size. You can even get acoustically transparent screens, and screens with acoustically transparent edges to allow even larger screens regardless of the position of speakers.

Benedict really wants big screen 4k for a cheaper price. Lots do fair play

He will probably eventually get it. Then complain he can't see a difference between 4k and 1080

No he won't. Hes not g-e-l.

He has three 4K TVs already. Sadly none bigger than 60". They just look silly in a dedicated HT room. :-(

 

[Benedict_Arnold]

Sony already makes a 100 inch 4K TV...

XBR-100Z9D.

Problem is it's $60K :-(

 

[ellisdj]

Why PJ still cost effective at that size

 

[Benedict_Arnold]

Why PJ still cost effective at that size

Agreed.

Right now the cutoff point for TVs seems to be 85 inches. I expect that to creep up to 100 inches this year though.

[ellisdj]

Have you seen a good pj on a 2.35:1 screen for movies

 

[Benedict_Arnold]

Fraid not. Only demos at BestBuy, and, of course, going to the movies.

The thing that worries me about PJs and screens is not only the extra cost of the screen, painting the room black, changing the carpet to black, painting the cat black.... etc. but also the cost and hassle of replacing bulbs every ten minutes. Our kids have a habit of playing video games until the small hours when we're asleep, and also of turning TVs on and off every ten minutes. We had a DLP TV a few years ago and we were changing the (expensive) bulb once a month.

 

[ellisdj]

Yeah you need to look after them

However the benq 12000 led 4k pj could be of interest.

I dont think it will have the highest native contrast but unless you paint everything and the cat black and wear a black velour suit you wont have to worry too much. I am pretty sure its instant on and off
Just buy a black diamond screen and job done.

Then have a tv for tv and a huge 2.35:1 screen for movies.

No black bars top and bottom its a true game changer for movies that are shot in that ratio which is most of them

 

[Benedict_Arnold]

The ideal for me would be a 140 inch diagonal 2.35:1 "wallpaper" 4K (or 6K given the aspect ratio) (O)LED screen without any tuners, speakers, etc., just a single HDMI input. But then I doubt very much anyone is going to listen to me....

 

[ellisdj]

I think phillips made a tv kind of that ratio might have been 21.9

You will be waiting 20 years for that

 

[bigboss]

The current bulbs last much longer than previous generations. Sony HW45ES for example, has a bulb life of 6000 hours, which is about 8 years depending on how much you watch.

My HW40ES projector is over 2 years old, but haven't needed to change the bulb at all.

 

[Benedict_Arnold]

21:9 is 2.33:1. Close but no cigar. The original CinemaScope was 2.66:1 BTW.

And yes, I fully expect Jimmy Hoffa and Lord Lucan AND Shergar to show up all at the same time before I see "my" screen. Perhaps I should just warm up my soldering iron...

As for bulb life, it's more the on/off/on/off again/on again cycles that kill them than it is the total number of continuous on hours. Until the "little cherubs" finally move out, I'm still wary.

 

[bigboss]

How many on / off cycles do you expect in a day?

You're just being paranoid. It's still far cheaper to buy a projector even if you need to change the bulb 2-3 times.
