Unconfirmed. Optoma theoretically should be able to move faster though since they are coretronic

Just ordered this projector and am awaiting delivery date. They say middle of November. Had my mind set on Optoma UHZ65 but for $1000 less and what looks like equal performance, I went with Acer.

I have demoed JVC RS520 (which had great HDR, but did not impress me in SDR), the Sony VW260 which had great SDR though on the low-side regarding light output, and the Acer V9800 which had good light, fantastic image in brighter scenes but bad contrast.

My hope is that the Acer VL7860 will be the perfect choice for me given the experiences with the three mentioned projectors.

Home Theater: JBL M2 & SUB18 powered by Crown and BSS.

I don't think any of the TI 4K Chip projectors have been confirmed to du 24p at 48hz as of yet, just that there apparently is a firmware update from TI that could enable it.

The VL7860 is more or less the UHZ65.

Because I use netflix/chromecast a lot (which is fixed 60P output), I've asked someone on the UHD65 thread (closest possible beamer to UHZ65) to force his oppo on 60P and play back 24P source to check for any judder.

The UHD65 perfectly catches the 24P in 60P and uses 5:5 inverse telecine (120hz playback, play every frame 5 times, fits perfectly) to play back. So if there is a 24P issue at this point, I assume that 24P in 60P works fine, which can be used as a workaround. Would be surprised that the UHZ65 would have a problem while the UHD65 doesn't.

I wonder how it does the sub-frames for XPR, since it seems like it would need to do one sub-frame 3 times and the sub-frame with other shift 2 times.

My guess is this is also limited to units that have the new version 8 firmware, from motion tests I saw the initial UHD65 firmware couldn't do 24p smoothly - but I think the v8 firmware they added 50hz and 24p support... A TI rep claimed 24p is done via 2:2 instead of 5:5 but its possible the person might not have known what they were talking about.

Maybe somebody could use a high speed camera and figure out what it is doing. The iPhone will do 250 fps I believe and some phones will do more than that, but not sure if the resolution would be good enough to see the 2 eShift sub-frames.

I've seen lately that some 4K DLP projectors require a trip back to the manufacturer for a firmware update (can't remember which models), which seems like a real step backward to me. No way I'm sending my projector back to the manufacturer every single time a significant firmware update is released, that makes absolutely no sense to me .

Do we know what the situation is in regards to firmware upgrades on both the Optoma UHZ65 and Acer VL7860 ? I sure hope that's not a situation common to all the TI DLP 4K chip models...

They have a USB port which should make user upgrades possible, but that functionality may not be built yet.

Odds are manufacturers are still doing the old rs232 serial port update method

From where did you order ? Is it available in the US ?

The worst problem with this Acer is the one memory bank. According to the French and German reviews, *any* change to a preset copies the changed preset into the one user preset.

Very problematic.

Not sure if the UHZ65 has the same problem.

Work around is accessing the ISF settings but this requires a code. Is this easy to get?

AFAIK, the UHZ65 has 3 user memories.

I have contacted Acer directly and even though they say that they'll sell the VL7860 in the US (the only place I could find online selling home theater projectors of the brand is Amazon), they do not know when nor at what price. Which doesn't sound very confident to me that it will happen, but at least they didn't say that they don't have plans to sell it in the US, which would have been a death sentence on that hope.

Thank you for checking that's good news. Looking forward to your thoughts on the VL7860, hopefully you will receive it very soon !

Delivery date still unknown My home theater should be complete December 1st, so I hope the Acer will be delivered at that time!

Do you know if it is true that the Acer uses a RGBRGB wheel and the Optoma close uses RGBY? That should result in a visible difference between the two.

Yes, the Optoma has a RGBY color wheel and the Acer a RGBRGB one. Therefore it seems Optoma is charging 1000 euros more and for a somewhat inferior color wheel to boot.

Hi Kraine,

What is the difference between "Calibrated" and "rec 709" and why such a disparity in lumens?

Thanks,
Mike

Hi,


here is the third test of the ACER VL7860 on internet ( Hong Kong )
http://www.avbuzz.com/audio-video/201711/vl7860/


The following scene is from LUCY movie ( UHD BR 2160p ) with a JVC X35 ( Lcos, e-shift 2K à 3000€ in 2012 ) :



Same image with ACER VL7860 ( UHD BR 2160p and Oppo 203 ) :



This Aceris a lumens gun :



The asian test emphasizes an excellent sharpness and depth of scene :



4K test using Cosemi HD US OptoHD HDMI 10 m :



UHD HEVC 10 bits 96Mbits/s easy :



The projo is at ease with ambient light and no light leaks on the horizon:



The backlight of the remote control is powerful (the 3D button on the bottom right is useless, this projo is not 3D compatible) :

The image from the Acer looks much better. JVC looks dim compared. The Acer VL7860 would be on my list if sold in the US.
You make a good point about the depth. I have noticed the same depth in my 4K UHD Vivitek DLP HK2288 projector. I think the depth is inherent in the 4K DLP technology and the laser increases it as well as better contrast and brightness. Very exciting technology looking forward to hearing more and thank you for the information !

How did you get a UHD disc to play on the X35? Is there some compatibility causing the lousy-looking image? Anyway, both the JVC and the Acer look like they could use a little calibration going from those pictures: The JVC looks dim and the Acer has its whites blown out. Regardless, the Acer looks visibly sharper in those pictures.

The X35 is a 5 year old projector, I have no idea why they would choose to show it, it's not even a 4K compatible projector, no e-Shift, HDMI 2.0, HDCP 2.2, WCG, HDR support, nothing. And it's nowhere near as bright as the current 4K capable JVCs, and not remotely representative of what you would get from a current JVC.

The Story is: the writer of that article bought his friend to see the demo of Acer VL7850, and after impressed by the picture quality of VL7850,
his friend watch the same senses on his old X35 and then text the writer said it was huge difference between two projectors and capture the screen.

Actually the demo VL7850 was only borrowed to the dealer for beta test, and it has been returned by the dealer before that article issued.
The dealer replied to me that there is no official sell price of VL7850 and the demo MAY BE ready for public this week, I am still waiting for his call.

So the picture of the X35 isn't even from the same setup? And not taken with the same camera and settings? There's way, way too many variables to draw any conclusions from those pictures.

The acer and the optoma come out of the same place there is that the software that changes .... with the laser it is 2 chromatic wheel 4 segments which filter the laser. Not really the same process as lamp. Then Acer made copied pasted for the description of other lamp projector. Warning. Hate that the two come out all the same to see who will be the winner of both.

That's not correct. The Acer has a RGBRGB color wheel, the Optoma a RGBY color wheel. If you don't know what you're talking about, then don't spread misinformation, thanks.
