I moved away from projection 5 years ago because the black levels and contrast ratio weren't very good. What's the maximum black level/contrast ratio that's possible with a projection system now and how does it compare to the best OLED/LCD televisions? Thank you.

10-15 years ago my father started working on a room that he had planned to make into a home theater. With the high price of projection he decided to go with a 65" rear projection RGB television. It wasn't until now that he finally switched to projection thanks to it's affordability and easiness to install. Home projection is seeming to become more and more common but it is still seen as something of an expensive luxury to the average consumer. My question is, do you guys feel that home projection will become much more popular and seriously compete with the average consumer looking to buy a larger television or is it doomed to always play a much smaller roll in consumer electronics?

Does one screen color (ie white or gray) lend itself to better performance with newer HDR/WCG capable projectors? or is your choice of screen color still dependent on your room and individual preference on image?

Thanks!

What is the minimum time in face-to-face training by ISF that someone needs to become a ISF certified calibrator? What percentage of people who do the training fail to pass the test and do not get ISF certification? Is there any quality assurance by ISF as to the quality of calibrations done by ISF certified calibrators?

What is your view on home cinema DLP projectors, has the technology become outdated and outclassed by the improvements in modern LCD, LCOS projectors?

Is their any chance the more desirable HDR and WCG will be available in 1080p projectors to lower cost or is 1080p considered an obsolete resolution? I guess the current crop of 1080p eshift projectors is an interim solution.

ok, loaded question (actually 2)

What causes the SXRD panel degradation in the Sony 4k projectors, especially the early models?

Rumors persist that Sony has developed a fix for this issue in its newer 4k models. What exactly did Sony do to keep the new models from excessive Degradation?

I am very interested in your perspective, seriously!

How important is a projector screen for getting the most benefit of HDR content? I'm looking into upgrading to a Sony vw675es (currently have a Sony hw30es), yet my screen is fairly basic (110" Silver Ticket). Do I need to also upgrade my screen to get the benefit of this projector?

If it matters, my room has no windows or light coming in; however, the walls and ceiling are fairly light.

I am brand new into the projector home theater game and picked myself up a Benq HT2050. I am very satisfied with the performance and the image size is around 140" right now projecting on a beige/grayish wall. I am going to permanently mount projector from the ceiling and trying to get an image size of 120".

My question is will a screen really make that large of a difference for the investment (this is a budget setup after-all, I got the projector for only $550) in it? If so, what budget minded screen would you recommend? I've seen 120" screens as cheap as under $100 at Fry's Electronics (manual; pull down...Inland is the brand name) to the often recommended Silver Ticket 120" fixed frame screen on Amazon (~$250) to seeing monoprice's 120" motorized screens go for under $300 when they have sales/specials.

Would you recommend any of those, and would they be worth it in budget minded setup of mine?

I'd like to second the question about Dolby Vision and also ask if you know a timeframe for when UHD/HDR projectors might be entering the $1000 range - is that something within 2 years or are we looking at 5-10?

A further question: do you know if more manufacturers are going to be using the DLP 4K chip soon, or is it just a couple as currently: are more 4K DLP projectors coming?

Do you expect OLED or some other technology to replace front projection in the next 5-10 years? In others words, will we see the screen that you can roll on your wall anytime soon?

If we do not have the minimum throw distance needed to fill a particular screen size what options do we have that will allow us to achieve such other than finding a 4k HDR short/ultra-short throw projector?

How often should you clean a projector? when the bulb needs to be replaces or sooner?

I'm curious why 4k native projectors are so expensive. More specifically if the issue is shrinking the lcos panels to fit 8M pixels into the same .7in panel or if the optics have to be upgraded so much to delineate 4x smaller pixels? Silicon has shrunk from 65/45nm to 10nm since 1080p panels were out, so I'm betting it's the optics, but I'm curious as to why there is a 3-4x markup going from high end 1080p to high end 4k.

Side question on this as well. How do the lens costs scale with the panel size? Say they bumped up the panel to .95in. Does the cost of the optical assembly cost jump drastically, or is it more economies of scale with these higher end projectors?

I was considering the Samsung Q9 88" despite it being EdgeLit (I will wait for price to drop) due to the fact that I have a bright room with 4 windows and a balcony with sliding glass doors. I am most interested in upscaled DirectTV content as well as Netflix, Amazon Prime Video, and HBO Go. 4K is just icing on the cake. I am about 12' from where the TV would be when watching and generally at the center or very close to it. I watch in the dark 25% of the time. I love the colors on the Q9, I like that it is suitable for gaming, no burn in worries as I watch a lot of news channels, and there was no TV in the size range (85"+) that I felt was in the same category when price is removed from the equation. Is there a set up/projector/screen you would recommend that I look at that you think would be superior and make me reconsider? Thanks.

Will we ever see cost effective projectors that needs no bulb replacement or have very long lasting bulbs. If so, how far off is that dream?

Laser projectors and Dolby Vision

Do you see Laser Projectors becoming mainstream and the main light engine for most projectors in the future?
If not, what technology do you see coming in the future that will help the Front Projector market keep up with the flat panel market in terms of HDR(specifically Dolby Vision)

Thanks.

Hi!

I've got two questions -

1. How long until will we see 4k projectors in the ~$1000 range
2. Is there any industry move towards making a 120hz capable projector? It would be fantastic for gaming!

Cheers,
Sean.

Unwatchable Image after calibration

I don't know if its appropriate on this forum, but I have experienced a problem with watching 4K/HDR since calibration was done.

My equipment is JVC D-ILA RS400 projector and OPPO UHD 203 Ultra HD Blu-ray player w 133" diagonal DIY screen. The projector is not true 4K but can accept a 4K input and does e-shift or pixel shifting to improve resolution.

The calibrator is affiliated with Lion A/V.

Prior to the calibration I had what I thought was a good image except that I couldn't tell any significant difference between image with a 4K disc and the image with a regular Blu-ray disc.

Now since the calibration the image from a regular Blu-ray disc is still excellent, but the image from a 4K disc is unwatchable because it is very dim.

I'm wondering what I should do next. I thought I might try stripping the HDR metadata from the player output as maybe the player just can't handle the HDR. I also could take out the new calibration and try to return to the original factory settings. I'm a little afraid to mess with the settings as they sound complex and I am not familiar with it all. I would just like to have the best image possible with the equipment that I have but don't want to mess it up as it looks like I have. Any suggestions.

Thanks, Larry Raulston

I know that 3D has mostly exited in the flat panel market, which is why I'm thinking my next purchase might be a projector. Do you think projectors can keep 3D alive in the consumer market?

And also, I generally sit about 6 feet away from my current television. I can move back about 2 feet but still can only be about 8 feet away from the other wall due to the unusual nature of the setup of my home theater room. I know little to nothing about projectors, but assume a short throw projector is in the cards. How big of a screen would you suggest going with, and is a projector reasonable from this distance or should I just stick with flat panel? Again, my motivating factor is 3D's not being available in regular televisions today.

Dolby Vision

I'll add my vote to the question on Dolby Vision. Specifically, do you expect it will ever cross into the front projector technology? If yes, any expectation on timing? What technological barriers/hurdles currently stand in the way?

If Dolby Vision is out of the question, what about HDR10+? I know it hasn't been officially released yet, but do we expect the standards to be more easily applied to front projector technology? Again, what barriers/hurdles would stand in the way of this technology?

To add to the DolbyVision/HDR10+ questions. If I understand correctly these scene-by-scene frame-by-frame metadata solutions need to know the capabilities of the display in order to work, i.e. each display provides its capabilities to the DV algorithm. The argument seems to be that with projectors the combination of projector, screen and ambient conditions are unknown and therefore DV etc is impractical. So the question is might the combination of projector, screen and ambient conditions be calibrated to one of perhaps several "standards" supported within the projector so that it would be possible to support dynamic metadata for a range of specific conditions?
