This will not hurt anything, if the projector doesn't support it, it will say "out of range" or the screen will be dark, simply hit escape or wait a few seconds for the test to automatically conclude. If it fails, you can retry it again at 120Hz, but instead change "Automatic" to "CVT Reduced Blank" and try again. If this fails, try 100Hz, if it works, try going up from there, maybe even just jump straight to 119Hz. https://www.blurbusters.com/overclock/120hz-pc-to-tv/ On this page, look for "Test to check for true 120 frames per second."
All this talk about 3d made me realize I haven't fed the 403 a 3d disk as of yet. I decided to use "The Hobbit: The Desolation of Smaug - Disk 1" for comparison. It was a bad choice due to overall darkness of the movie and lack of color. Greys and greens. I played about a hour of it in my Benq HT3550. 3d on the HT3550 is good, but just good. The movie setting was a little too dark for the HT3550 and I had some sync problems with my Benq glasses. I then played the same scenes to a HT5550 which I'm "evaluating" to replace an Optoma UHD 51alv which died prematurely. The UHD51 did excellent 3d. The Benq HT5550 not so much. It was dimmer than the HT3550 and gave the same sync problems using the same glasses. Both projectors were in non cinematic enviroments with the exception that both rooms were made totally dark. Throw distance was approximately 10 ft for both projectors and both shot to a 100" Cinematic White screen with 1.1 gain.

Now for the ZH403. The Game Room is smaller than the two previous rooms and the projector shoots to a 90 inch screen of the same type as in the other two rooms, from a distance of 8.5 ft. Oppo BD players provided the feed for all three projectors. The Game Room can also be made totally dark. The 403 is a light canon and that was enhanced by the shorter throw and the smaller screen. The same disk was use but this time I watch the whole disk. The 3d was so good that I could not stop watching it. I've owned 4 Benqs and this is my 3rd Optoma and this one plays the best 3d of all. Settings were default; 3d with Dynamic Black. Colors were very good when there were colors, but in a few scenes close up facials showed a slight purplish overshadow. If I wasn't looking for it, I wouldn't have noticed it. Detail was very sharp. The Benq glasses worked flawlessly. I don't know if it's the brightness, the laser, or the color wheel, but 3d works on this projector, or at least it does for this one disk.

Reply from Optoma: 1080p, 2D gaming is done at 60hz. For 3D gaming, [email protected] will run in 144Hz; other 3D timing will
run in 120Hz

I watched Transformers: The Last knight which was shot in Native 3d and would call it watchable. The Avengers End Game was slightly worse, and Capt Marvel was not even watchable. The only adjustments I made was to the Brightness mode, alternating between Dynamic Black and different %s of brightness. Nothing helped.
I'll try a different player next. Hard to explain after The Hobbit showed so well.

I'd suggest HDR Dynamic Range = Standard with Gamma = 2.4, with DB on. The info menu input should show 2160p, 24hz 4:4:4

What are you using as a source?

EDIT: OK. 3D! Not HDR...

Found it. Bad pair of 3D glasses. I've been using these for a couple of weeks and keeping them charged. I think the battery lost its charge capacity. I was using an Oppo BD 103 and a Panny 820 getting the same results from each one. Changed glasses and things are great again. The 403 does really good 3D.

They are even using the same photo of the ZH403 in the HZ40 marketing material (same serial #) [IMG class=inlineimg]/forum/images/smilies/smile.gif[/IMG]
Zombie you was right. The US version of "HZ40" is being called HZ39HDR and its exact copy of the ZH403. If the ViewSonic X100-4K turns out to be a turd, the HZ39HDR/ZH403 will be my next projector.

^^^Thanks DunMunro^^^


Looks like an interesting option...especially if you don't have total light control and you can put the extra lumens to good use.

because my old lg pa70g is nearly dead i've ordered one today.
i hope i can cope with the rainbows. on the lg u can notice it clearly if you purposely do fast eye movements. especially when watching b/w material. but then its a led projector with faster cycling than the 4 segment wheel of the zh403.
On the optoma uhz65 (same duracore engine) thread someone stated that the perceived rbe is dependent from brilliant color settings.
i will definitely check this out
do you guys think the black levels will be comparable to those of the pa70g (500lm/1400:1 native cr)?
are there very noticeable side affects of the dynamic black feature?

hi, I have the ZH406 which is basically the same projector. I also have the LG PF1500 LED projector as well. I would say they are about the same with RBE, a little more noticeable on the Optoma due to the extra brightness. .

The black level isn't great at full 100% laser, these are much brighter than the LED models but overall looks very good with most content. I noticed some issues with the dynamic black, especially in low APL scenes there is a major drop off in light output and is jarring to see it come in and out the dynamic black. The interrogation scene in Oblivion with Morgan Freeman shows what's happening.

let me know if you have any setup questions when you get it.

DB on the ZH403/406 has only the one setting. On the UHZ65, for example, DB can be set to DB1, 2, or 3, with many users favouring DB1 or DB2. Perhaps it might help to write to Optoma and request a firmware upgrade for the same DB settings as on the UHZ65?

thank you for your response. thats no good news for me. i've had the pf1500g at my place but returned it because of very bad black level, poor native cr(600-1100:1) and much more noticeable rbe compared to pa70g.
so it looks like the zh403 wont fit my requirements but its a last try before accepting to rearrange my ceiling mount and living with bigger housings extending in the living-room at the entrance.
maybe i can find settings to lessen the rbe.

hi, give it a try it might be ok for you. I mainly use my laser DLP"s (Optoma and Viewsonic LS800WU) for ambient light viewing and the RBE isn't really noticeable to me in those environments. when the lights are out watching 24 frame content, it can be a bit more noticeable. It's the overall nature of the RGBY CW and a lot of light output.

I have several other DLP's here, some of the best for RBE are the RGBRGB CW Sharp 30K and the Planar 8150 and the high frequency LED's in the Runco q750. I rarely ever see RBE with those projectors.

keep us posted when you get it, one benefit is it has a sharp lens which is nice considering the relatively low price point.

Can this projector do proper 24p/23.976? I thought this was table stakes in 2020, but this thread makes me think otherwise: https://www.avsforum.com/forum/68-di...-proper-2.html

It's ability to display 24p content would be no different than any other 1080P Optoma DLP projector. 4K XPR projectors have some additional complications with 24p sources because of the timing issues associated with the double shift required for XPR.

And I guess other 1080p projectors from Optoma are fine?

Looking at test reports they seem to do fine and I had no issues with an Optoma HD66 or my current BenQ W1070. In the other thread I had to do quite a bit of configuration to get a 24p signal, where the source didn't correct for the 24hz to 60hz frame rate (as both my Sony X700 and UB420 were doing from BDs or streaming), or at least minimize it's effect, so I really think that this is a non issue.

A number of Optoma 1080p projectors state:

24p
Most movies are shot at 24 frames per second (fps). To preserve the purity of the original image, Optoma projectors can accept high definition sources at 24 fps to display movies exactly as the director intended.

very good sharpness and overall suprisingly good lens quality i would say.
the black level is indeed independent from the power level of the laser. i can imagine that with the help of a nd2 filter the black level would be ok/good.
sadly i couln't find a setting to lower the rbe to an acceptable level. yes with brilliant color set to the lowest setting and turning dynamic range off it gets better. but still very pronounced on credits and so on.
my next try to avoid the new arrangement in the living room will be to set an external fan next to those of my good ol LG PA70G. which hangs and shuts down sporadically somewhat dependent from the temperature and air flow of the living room after 6 years of usage. this way i can wait further for good contenders.

I ordered a 82mm nd2 for my HZ39HDR and two things... 1) the filter was just barely too small to fit over top 2) while black levels obviously were improve, they were still too raised

I want to to try a 86mm nd4 next, but I can't find anywhere in Canada selling them at the moment. I'm also considering jumping right to nd8. There are also variable nd filters, but I'm not sure if the quality will be up to snuff

What size and type is your current screen?

A larger, lower gain, screen might help.

It's a grey painted wall (probably like ~1.2 gain) @ 140". Can't go any bigger, the projector is already at the very back of the room on a shelf

i use this paint:

https://ca.rosco.com/en/product/tv-paint (TVwhite)

It's a .6 gain grey. 1.2 gain is way too high for a ZH403.

I'm not sure what the gain is, it is just a home interior eggshell grey paint so I assume the gain is a bit above 1.0 but who knows. Maybe it is below 1.0. Repainting it isn't an option though

The HZ39HDR is a 4 segment wheel RGBY, and the HD39HDR is a 6 segment wheel RGBYWC. The HZ39HDR is a bit bigger and heavier. I'm also guessing the HZ is a lot closer to 4000lm in reality than the HD is, even though they both claim 4000lm. The throw ratios are slightly different. The HZ hasn't had the planned 120Hz enhanced gaming firmware update yet, while the HD already has it. I believe the HD doesn't have a IR receiver on the front of the projector, which can be annoying depending on how you mount it, while the HZ does.


Essentially the only major difference will be laser vs lamp once the firmware update is out though

my next try to avoid the new arrangement in the living room will be to set an external fan next to those of my good ol LG PA70G. which hangs and shuts down sporadically somewhat dependent from the temperature and air flow of the living room after 6 years of usage. this way i can wait further for good contenders.
hi, that's unfortunate about the RBE, I went back and compared the Optoma ZH406 to the Viewsonic LS800WU and noticed less RBE on the Viewsonic vs. the Optoma even though the Viewsonic has a 1000+ lumen advantage. ZH406 is ~1700 lumens D65/R709 compared to the LS800WU which is ~2700 lumens D65/R709.

The viewsonic is 2x the MSRP though, maybe they did something different with the CW timing.

What about the Presentation preset on the Optoma. PC measured it at 3000 lumens.

I just bought a ZH406 and found the color a bit off watching movies in SDR. Mainly blue looks a bit overcook and purple. It is relatively easy to fix by dropping the blue hue under "color matching". But the default for HDR is totally unwatchable. The whole picture looks pale in a yellowish and purplish tone. So I hope other owners of this or any Optoma laser projectors who find their HDR picture looking good can share your RGBCMYW values under "color matching" and RGB Gain/Bias so I can give it a try. I bet nothing can make my HDR picture look worse than what I am having now.

Remember to set the colour temperature first (Typically D65) before adjusting anything else.

The HDR IQ sounds like an HDMI issue and/or a colour space issue. Generally speaking you want YCBCR output from the device and it's output info should match the input into the ZH406 (Menu->info). ZH406 colour space should be set to auto.

What is the source video device and is there any other devices in the HDMI path? Remember that you're passing a 4K HDR signal and that it can require a full 18gbps signal through the cables and any devices, such as a receiver.
