Not focusing

So I'm having an issue of focusing. I am able to get top of screen focused but not bottom. I set it up where keystone is minimally needed.

120in screen
Throw distance in 14ft

Any guidance ?

Do you have the same issue when you’re square with the screen? Try disabling the keystone and placing the projector (temporarily) so you’re square at all four corners and see if you still have the focus problem.

Sage,

Thank you for the advice. Placing the projector squarely center helped. So I guess it's not the projector but the user. Lol. I'm still learning. Made a few adjustments and I got it MUCH better but definitely cannot make both top and bottom of screen perfectly clear. But it's close now.

Played some pc games over the holiday and it was great.

Will be doing an RMA after the first on Jan, so I can get the updated firmware. 3D switching is messed up as others have reported.

For those running through an AVR, I decided to try using the HDMI upscaler in my Denon X4300h last night.
I set that to convert my Sky signal (1080p) up to 4k 50/60 and I have the say the results were superb. Much better than using the inbuilt TK800 scaling.
There was a noticeable perceived improvement in resolution/detail and I was really surprised to be honest, as I've never noticed much difference before in using any of my previous AVR upscaling as opposed to display scaling.

FYI, when playing around with 3D modes etc. from my pc I've also found that the denon does 100% pass through a 1920x1080x120Hz signal without frameskipping. That's according to the blurbusters UFO test. There's probably a reasonable chance that older and other Denons do as well. It's not something that's covered very often but from what little info I'd seen in the past, the Denon's seem pretty good in this regard. I assume Marantz is the same.

Bit of a niche thing but info is sparse.

I am newbie and for quite sometime I have been reading through threads on this forum for information and finally got myself a TK800. For the past 5 years an entry level Samsung 51" plasma tv was my only/main screen for viewing. The reason I went for it is because I am planning to use this as a TV replacement in living room where the light can be partially controlled. Out of the box I was not happy with the picture irrespective of the mode and time of time of the day but with settings suggested on Projectorreviews it got better.

I am currently projecting onto a wall (painted in ivory/cream) for an 120" diagonal image but looking to get a screen which would go well with the TK800. The max I would want to spend is abt $300. I am aware that I can't get a Plasma like image but which of the below screens would get me somewhat closer to it.

STR-169120-G Silver Ticket, 120" Diagonal, 16:9 Cinema Format, 4K Ultra HD Ready, HDTV (6 Piece Fixed Frame) Projector Screen, Grey Material
or
STR-169120 Silver Ticket, 120" Diagonal, 16:9 Cinema Format, 4K Ultra HD Ready, HDTV (6 Piece Fixed Frame) Projector Screen, White Material

Suggestions would be much appreciated.

Get the grey 100% get the grey tee he tk800 will do nothing but impress you and everyone viewing it on a grey screen. The white washes out with any light in room where the grey does not

Thanks for the suggestion, personally I too was leaning towards the grey but wanted to see if fellow members suggest the same.

Has anybody on the forum paired the TK800 with this grey screen ?

I am an amateur but gave a go at the picture settings and below is what I could come up with. My source was Netflix streamed via 1st gen Chromecast connected directly and projected a 110" diagonal image on to a cream colored wall. I feel this could be tweaked to produce a better image by somebody with a good eye for colors and dedicated screen. I'd really appreciate if someone would want to give this a shot and post their comments/tweaks.

Cinema Mode as base

Brightness 50
Contrast 49
Color 50
Tint 50
Sharpness 6
Gamma 2.2

Color Temp Normal
Red gain 100
Green gain96
Blue gain 102
Red offset 254
Green offset 252
Blue offset 256

Color Management
Color Hue Sat Gain
Red 184 200 212
Green 200 200 200
Blue 200 200 200
Cyan 200 200 200
Magenta 268 200 212
Yellow 200 200 200

Noise reduction - Off
Light mode - SmartEco
Brilliant color - On

For some (like Avengers Infinity war) changing Gamma to “BenQ” gave the image a nice sheen to it.

This could create unrealistic expectations. Every screen type has tradeoffs where some performance areas are improved at the expense of others. The grey screen will also wash out in ambient light, only somewhat less than the white. The flip side of the coin is that the grey screen will produce a duller image as Silver Ticket states in their description of how to choose white or grey:

Makes a very good point. I can only speak from experience. Between the white and grey I've had then side by side and calibration changed tiny bit by the grey was just as bright as the White with added contrast. Wash out was clearly less noticeable for my viewing area with the grey also gain is changed with white to grey

I'm cross posting this from the new BneQ PJ because I thought people who are going to buy this should know:


Well sadly I am returning my TK800.

I love everything about it except 3D. I watched a few movies and no matter what the picture is a tiny bit blurry and the color is off, like no contrast. That weird green tint is always there.

I hooked up my HD142X again to compare even using DLP Link and sure enough the color is better, contrast much better, and picture is more clear.

Sucks too because I love the 4K HDR presentation.

3d cuts down to 720 and depending on what glasses surely you'll get blur. Another reason 3d isn't pushed at all anymore with home theater or even rarely at the big screen. Truly unless you watch tons of 3d I can't see getting rid of it for that reason. The HDR and "4k" alone should make it well worth keeping.

Ya I have a billion 3D movies and it's a big part of my home theater experience.

If I had to choose between 3D and 4K I'd choose 3D.

720p looks like **** at 160"

Is there a reason it's not 1080p and will the next generation be the same way? I don't want to have to buy a lcos, I really like DLP.


Edit: sure enough the specs say 720p in 3D mode, but the UHD51 says 1080p24 for frame packed. Is this accurate the optoma is 1080p but benq is 720?

I haven't played much with the 3d on mine yet, but when I did, the picture was bright and colorful. I've had 2 other DLP projectors in the past and I haven't noticed that this is inferior to either of those.
Have you already sent it back? Were you trying 3d bluray or something else and what player were you using? Also, do you know what version of firmware you're on?

I'm pretty sure 3d isn't output at 720p on this projector. It's a mistake/misunderstanding of the specs. It only does 720p frame sequential input, but I thought it's the same as all the other 4k projectors that support 3d in terms of how it works. Some of the other models listed up to 720p 3d in the specs but I think they were wrong. They're all fullhd 3d for framepacked 3d. Since they're all native 1920x1080 it wouldn't make any sense to scale the output any lower, I think it just applies to the input as I mentioned.

As someone else said, a slightly green tint is normal from the LCD shutterglasses, I get the same on my other 3d display. It's strange that it's so bad, I wonder if different glasses would help? I don't know if the TK800 is so called 'triple flash' or not.

BenQ TK800 Announced.

The TK800 supports 1080p/24 frame packed 3D. So if you’re playing 3D from a Blu-ray Disc you should have no issue getting full 1080p resolution. I have used the TK800 with Blu-ray 3D and it displays Full HD 3D Blu-ray without issue. In fact, I would say it’s one of the better 3D projectors I’ve used simply owing to it’s brightness.

There is an issue with loss of sync with off brand glasses when using HDMI 1 that I detailed in my review. Loss of sync can manifest itself in a number of ways including color shift. In addition, the TK800 is particularly bright and DLP link operates by a small optical sensor in the glasses. The brightness of the TK800 can wreak havoc with the cheap sensors in some off brand goggles. For whatever reason, I had fewer issues with HDMI 2 (the 1.4a port). You might want to try and replace your 3D goggles and see if that helps.


What to do if you find yourself stuck with no hope of rescue:
Consider yourself lucky that life has been good to you so far. Alternatively, if life hasn't been good to you so far, which given your present circumstances seems to be more likely, consider yourself lucky that it won't be troubling you much longer...

All I'm saying is none of my 1080p displays have that crazy ass green tint. It's not the glasses.

if I play it on my 1080p without glasses it's not green or anything z it doesn't change the entire gamut and brightness and force some messed up gamma mode, it just plays in 3D.

The TK800 adds an insane green tint that yes sort of goes away with the glasses but it washes away some detail and color. This is my 2nd unit since the first had a lens issue where the left side is blurry, they both do it.

There is no reason they couldn't have left all the settings alone except to give me regular 1080p 3D output. I put on Beauty and the Beast to test (the new one) and no matter what settings used it looks better on the 1080p PJs.

I'll play with it some more but I'm curious if the UHD51ALV does that super green tint in 3D mode or what.

OK so I'm getting 1080p on my 3D blurays, that's good but they didn't need to jack with the settings and not allow me to undo it. I literally just want the same look and quality that my 1080p projector gives.

The tough thing with current gen 4K projectors and 3D is they are using 3-4 processing chips. One for 4K xpr, one for 1080p, one for 3D, etc etc. This is why they are not user upgradable. Because their is not a single SOC.

I like the 3D on the TK800 but I agree that 3D took a step back even from the 6 years old W1070.

The HT3550 and next TKxxx aim to fix that with and integrated SOC and much better black levels.

Ya I hope so, the thing is I really love the TK800 and wanted to keep it but I do so much 3D I just can't.

Hopefully the next gen gets it. I'm still curious as to the optoma performance

My point is the TK800 is VERY bright and I believe uses a sync on white which makes it especially challenging for cheap glasses. I'm not discounting your experience, I'm saying that I couldn't use the same cheap glasses on the TK800 as I used on some of the 1080p models I've reviewed in the past.


DLP link is a nifty and cost effective way to get 3D. Since it uses an optical sensor to sync, manufacturers can save by not needing to include a wireless transmitter and 3D glasses are available for SUPER cheap. In fact, a quick look on Amazon reveals that cheap, off-brand glasses are pretty much the only offers these days. To be clear, the TK800 isn't the first projector I've had sync issues with. The BenQ MH530FHD is probably the best 3D projector I've ever used. That model is bright enough that some of my cheaper DLP link glasses would occasionally lose sync with the picture. Upgrading to higher quality glasses solved this issue for me. Hell, there was a guy on this thread who solved his issue by darkening the plastic covering on the sensor on his no-name glasses.

If it's not a sync issue then I'm not sure about this green tint you're experiencing. Do you see a green tint with your glasses off? If it is present in the image at all times it could be a settings issue. I did not experience a green tint on my TK800 review sample. Without being able to see your projector I'm at a bit of a loss as to why this is happening.

What to do if you find yourself stuck with no hope of rescue:
Consider yourself lucky that life has been good to you so far. Alternatively, if life hasn't been good to you so far, which given your present circumstances seems to be more likely, consider yourself lucky that it won't be troubling you much longer...

The AV Tech Media Awards said that the BenQ TK800's small and cute design and simple setting method will make the entertainment effect of 4K large screen popular to more people. TK800's HDR mode provides rich details and sharp images; with 3000 lumens high brightness and 3D functions, the picture is both stereo and delicate, and the TK800 is quite suitable for home entertainment.

Hi All,

As Benq W2700 is likely to be available in March / April, is it still worth buying Tk800 now. Is HDR expected to be significantly better on W2700 with DCI-P3 coverage of 94%,even though it will have less lumens. Appreciate your thoughts. Thanks.

From what I’ve heard the main differences are a modified DMD without a light boarder (and possibly better contrast), new lens, and better 3D detection.

Do any TK800 owners connect a PS4 Pro via a receiver (Denon) output to the projector?

Can't seems to get the image to display on the screen. Sound is being outputted though.

Have fiddled with various settings on the Denon but to no via.

Any help is appreciated.

TIA.

Hi all,

I'm new on this forum and I have problems with my tk800.
I had exactly the same problem as described above with a 4k source (NVidia Shield) and a Focal soundbar with HDMI ARC.
So I decided to bypass the soundbar and plug the Shield directly on the TK800 and I still have the problem: the source is not detected.
I found how to solve it: just reboot the tk800, and then the source is correctly detected. So that's just boring because each time I have to boot twice.
I don't have this problem with the non-4k source I use on hdmi 2 (nintendo switch).
My firmware is 1.0.0.0 and I tried to reset all settings but it didn't solve the problem.
Do you have any ideas? thank you very much.

Have you tried any other 4K sources directly. I use a Roku Streaming Stick Plus and the Tk800 I just got with the same firmware always auto detects Roku.

Are you sure your cable is sufficient to pass 4K/60? The fact that it works after a reset could be an indication that your source is connecting at a lower resolution. Keep in mind that the TK800 displays 4K by default so even if it is receiving HD it will up scale the image and list 2160p on it’s info screen.

I had a similar issue between the HT2550 and my x800 when I first upgraded to 4K. If I forced the x800 into 4K I would get a ‘no source’ on my projector. But once I power cycled the two the x800 would detect the HT2550 as a 1080p device and reduce the resolution to 1080p. An upgrade to my cable fixed this.

What to do if you find yourself stuck with no hope of rescue:
Consider yourself lucky that life has been good to you so far. Alternatively, if life hasn't been good to you so far, which given your present circumstances seems to be more likely, consider yourself lucky that it won't be troubling you much longer...

My info screen for the TK800 shows the source input signal (eg. 1080p for HD cable), then, of course upscales it to 2160p for displaying. If I see 2160p for an HD signal from streaming, that's because my Sony bluray upscales to 2160p if it senses the projector can handle it.
