Re: 4K HDMI cables. I HIGHLY recommend the S6 line from Sewell Direct. I needed a 40 foot run and this is one of the only HDMI cables that supports 18.6 gbps at 40 ft. I have had zero issues with handshaking with a 30 ft hdmi run from my Xbox One S to my Denon 6300 then back 40 ft to my projector.

Cool if the XPR can be turned off for 1080P. You could pause the intro or some other space scene and toggle "Silent" on/off to see if contrast and black floor differ.
So I spent a good deal of time switching back and forth between 'silent mode' on and off.

Silent mode does indeed return the projector to a native 1080p image although it doesn't actually tell you that (the input still reflects the source: 3840 x 2160). But it's easy to tell when you switch to the lower resolution. Just to be sure I confirmed with test patterns and it is indeed 1080p. Took some shots of a 1080p line pattern so that you could see. I know scotty says he noticed a little better contrast and I might believe that could come down to his better theater room. If there is an improvement it's difficult to see and any small gains you might get in contrast are obliterated by the noticeably chunkier image. Also note the ease with which the camera picks up the color separation-- I believe silent mode is running at a very slow color wheel speed as well. For the record: silent mode is aptly named. The HT2550 BenQ sent me is far from noisy but in silent mode I couldn't even tell it was on!

The first image is silent mode OFF (XPR engaged) and the second is silent mode ON (XPR disengaged).

I wouldn't expect people to give up 4k resolution just for enhanced contrast. I was just curious if it would give a clue to how much of the low-contrast issue was due to the smaller chip vs the XPR effect of overlapping pixels. Scotty says XPR is costing some contrast, and you say it is not obviously so. Still inconclusive, then.

I don't understand why the color wheel speed would slow, unless the "purpose" of silent mode is that very small niche population that intends to use it as a bedroom TV and watch late at night without the color wheel whine waking the spouse.:laugh::laugh::laugh:

Hey! My girl is in bed watching my HT2050 on the bedroom wall as we speak! Lol! She actually says the fan noise helps her fall asleep though... :D

You could place the HT2550 in a table, yes. I do practically the same thing with my HT2050. Just keep in mind that you'll need to sit a far way back unless you want to sit off to the side.

If you are interested in 4K and how it compares you could always purchase the Ht2550 from Amazon/BenQ as they have a good return policy and then judge for yourself.

As for distances, bookmark this site:

Is the 4k noticeably better than the 1080p from a better 1080p projector? Also when I tried putting my 2050a on a table, I had to literally keep it few inches form the floor for it to project the size I wanted from the distance I wanted on the wall. Before I buy the 2550 to test, I want to make sure how far do I have to mount it, and does it have to be closer or further than the ceiling? Right now I have a room where I have flexibility where I mount my projector, so don't want to discard the 2550 yet, just because it doesn't have lens shift.
Also, does turning a projector on and off multiples times (2-3 times) a day affect it?

Oh yes, it's noticeably sharper WITH A PROPER 4K SOURCE. By proper source I mean a well mastered UHD bluray, quality stream or PS4 Pro/Xbox One X game that supports 4k, 4K checkerboard or 1440p upconvert.

With 1080p content, ironically, you're better off going with a 1080p projector with higher contrast and better blacks. Due to the relatively low contrast and higher black levels on this projector 1080p ends up looking just OK (contrast can make an image appear sharper than it really is-- just ask someone with a DARBEE).

I'm not sure what your question is regarding placement. The HT2550 has a longer throw than the TH2050-- which means it must be placed farther back to create a similar screen size. It also has no lens shift but has a fixed vertical offset which you need to take into consideration when mounting. See here: https://projectorcalculator.benq.com/

Hmm, you have me concerned now. I have an Optoma hd29darbee, and I must say, 1080p 3D bluray is the best I've ever scene on that. I was hoping these new 4K projectors would upscale cable and bluray 2D to look better, since I rarely watch 4K stuff anyway. But based on what you are saying and what I've noticed in a lot of reviews, 1080p upscaled to 4k actually looks soft compare to 1080p projectors. Hmmm....:(

I wouldn’t say it looks soft and the processing on the HT2550 is excellent. Here is what I’m trying to say: when watching a 1080p Blu-ray I can switch back and forth between the HT2550 and the HT2050A and I prefer the image of the HT2050A for 1080p. The contrast is better and the blacks are deeper and while a 1080p image on the HT2550 looks mildly sharper thanks to the better pixel fill it’s not enough to overcome the contrast advantage of the Ht2050A. When you feed the HT2550 a UHD that script flips. Watching the Martian on the Ht2050A after watching it several times on the HT2550 the HT2050 looks— jeez I don’t want to say soft here but— it just lacks the level of sheer detail and clarity the HT2550 is capable of. Playing Shadow of the Colossus on the PS4 is a beautiful experience at 1080p but on the HT2550 at 4K (technically 1440p upscaled) you can see individual strands of grass rushing past the screen as you and Argo ride across the countryside. It’s mesmerizing. But all this comes at a cost: as I stated in my review, the contrast of the HT2550 is hampered by poor black levels caused by the XPR or, potentially, the light border (no one seems to know for sure). If you’re not interested in 4K it’s silly to upgrade to the HT2550– your money will go farther with a 1080p projector. BUT, if you want a 4K projector and you want great color your choices right now are this HT2550, the $2500 Optoma UHD65 with a calibration (the out of the box color accuracy is just not there in the Optoma), or the Sony 285ES for 5 grand.

I think these new projectors have come at us so fast we forgot just how insane 4K for $1500 actually is!

@sage11x: Have you tried watching a 1080p bluray that was upscaled by your bluray player first and not by the projector, vs. 1080p from the player to the projector to let it upscale? Although, I don't have the 4K projector to try it, I know my Sony player will upscale to 4k if it sees a 4K TV, but I can turn that on or off. I wonder if the scaler in bluray player might be better than the scaler in the projector.

My guess is it would depend greatly on the player. I have a Sony 6700 upscaling player but my guess is the internal scaler in the BenQ is better. If I had to guess the scaler in my Sony X800 would be better still. I can try and test for this and tell you what I find. What player are you using?

I have a Sony 6700, but I don't own a 4K projector yet. I was looking forward to watching 1080p blurays upscaled, but I'm having concerns that it's a waste of time and money. Thanks.

Fair enough. Luckily I have the same player so I should be able to give you a good idea of what works better: the player or the projector.

Hi everyone,
After returning my BenQ HT2550 I haven’t been very active lately. I just read a new article on the Verge. The article is about a new model from BenQ named the TK800. Apparently it has a higher lumens spec, after reading this I presumed that it has a clear segment in the color wheel. Reading further, the article states, “BenQ also claims the TK800 has improved color accuracy and reproduction.” Also, I’m guessing that the 3D issues that BenQ has stated requires a hardware fix will be updated on this model. The article also has a reference to my topic “What constitutes 4k ?” Here’s the link to the article.

As I stated in the other thread, I just ordered a HT2550. I am upgrading from a HT3050.

Also, I'm currently using a Sony 4K (I think its the 800) player and I can play 4K media and send a 1080p signal to my HT3050.

I'm hoping my 15 foot HDMI is up to snuff for the HT2550.

If I do not like the HT2550, returning may be difficult as Best Buy has changed their return policy for certain items. Projectors come with a restocking fee. I hope I like it and I can plug and play it on my 104" 2.35 aspect ratio screen.

I had some difficulty with HDMI. 15 feet is the absolute max I would recommend and make sure you keep it away from parallel runs alongside power cords. My high speed, well shielded 25 footer would not work. I ended up with a 10 foot cord and just moved my Sony X800 closer to the projector. My X800 is also finicky and will sometimes require a power cycle before it will recognize the HT2550. Ironically the PS4 has no trouble. One tip is to leave your X800 in auto resolution that way if your cable isn’t up to snuff the player will hopefully scale back to 1080p.

I decided to play with the HT2550 a little more this week and made some small tweaks to the picture settings. I’ve decided to post these settings for anyone who might like to compare. Remember: it’s not good to simply copy settings but this is a good point of reference to see how your unit/tastes might compare. These are NOT calibrated settings. I arrived at these by using my DVE Blu-ray as well as a liberal sprinkling of 4K/HDR test material. I’m only posting settings I actually adjusted from default.

Picture mode: cinema
Brightness: 51
Contrast: 57
Sharpness: 5

Advances menu
Gamma (SDR): 2.3
HDR Brightness (HDR): -1
Cinema Master menu
Pixel Enhancer 4K: 2
DCTI: [on]
DLTI: [on] (per Chris Eberle’s recommendation in his review)

All other settings are in their default setting and Light mode is set to SmartEco.

Can anyone confirm if the new units have the updated firmware? I really want to order one but I have literally hundreds of 3D blurays and don't want to have to return it.
