Sony HMZ-T1 HMD Owner's dedicated thread - Page 94

Not surprised about gray blacks, after all this is not OLED display technology that has blacks comparable to the defunct Pioneer Kuro models, but is LCoS.

As I suspected based on the technology, it has rainbow distortion, RD, at least under some scenarios.

It is impossible to convey how bad it is verbally, and some people not only aren't bothered by RD, they don't even see it at all, so it's not a deal breaker for me, but I thought to point it out:

" When moving your head quickly up and down the display technology shows his weak spot: All white colored text on the screen will leave a Red, Green and Blue trace. The displays work by quickly showing just one color at the time. But when using the HMD to watch movies and play games I never really noticed it so it won’t disturb any normal use with the ST1080"

Source.

Also, I suspect the reviewer's comment regarding "blurry corners", elsewhere in that review, pales to the issue with the Sony, which he makes no mention of having ever tried, although he does allude to them and concludes:

"My first opinion about the ST1080 is very positive. There are of course a few things that could be better. SiliconMicroDisplay however did a great job and really surpassed other bigger companies. They announced a good product and just delivered it."

Been using my hmz-1 for mostly movies latly and i feel its better suited for animated 3D movies than "real life" titles ... Tested the referance pop out movie sammys turtle tale where there loads of objects that pop out of the screen ... Do see the pop outs but a 3DTV gives a better feel of how far out the objects are ... the snake in the jungle is a good test of that..

We are working on a solution to block light from the HMZ while viewing now. It will be a cover that wraps over the HMZ and then straps on the back of your head. It will block almost all light and make the viewing experience even better.
We thought of many different ways to do this, however using a soft fabric with the right shape seems to be the best so it won't harm, scratch or ruin your HMZ.

A prototype will be done later today for testing. And later this month we will start taking ONLY pre-orders until we can catch up more on the cushion pad orders.

Towards the end of June we should have a much faster shipping and be able to make pads and light blockers fast as my wifes quitting her job and can stay home working on all these. (She really wants to stay home and do this instead of working)

We will also be working on headphone covers to protect the soft material Sony used. And later down the road cushion pads and a light blocker for the new SiliconMicro ST1080.

Not true for the HMZ-T1. The OLED display uses all white pixels with an RGB colour filter overlay. Therefore all pixels fade equally and no colour shift occurs over time.....just dimmer.

Only lg uses woled the sony uses rgb without the exstra white sub pixel

Correct. According to OLED-Info.com, the Sony HMZ-T1 uses ECX332A panels, which are white OLEDs with a CF (color filter) overlay.

http://www.sony.net/Products/SC-HP/c...cx331_332a.pdf

Its still a rgb with a blue pixel that will fade with time, the white oled is used to bright up the picture to "help" life time on the blue pixel.

Having sum thoughts regarding the lenses infront of the oled screens on the hmz-1

Seems its those who makes the image slightly blurry on the sides is it possible to replace those with better optics?

Incorrect. You might be confusing a different OLED panel, used in some other devices, for what the HMZT1 uses. There are only white OLEDs in the ECX332A and ECX331A panels, so they all fade evenly. They derive their coloration through a CF (passive color filter) which their light then passes through.

Here's direct evidence from Sony themselves that the panels used in the HMZT1 [the EXC332A] uses the "new method":




"Incorporated in ‘HMZ-T1’
Head Mounted Display "Personal 3D Viewer"

"The new display also incorporates technologies adopted in the electronic viewfinders of Sony new range of digital single-lens cameras, announced on August 24, 2011 (“α77”, “α65”, “NEX-7”).


Key Features


Ultra-small size / high definition image quality

Sony has succeeded in creating this ultra-small, high-definition 0.7 inch display by realizing a pixel size of 4um x 12um. The ultra-small size and high-definition image quality were achieved by adopting a color separation method that overlays a color filter over the top of the white organic EL layer."

Same as lg been claiming but been proven wrong on .. the color filter is a oled layer by rgb colours that the blue will fade with time.. the white just boost the brightness up

I gave links; that didn't seem to work. So I then brought the actual diagrams to the thread and highlighted with bold text the pertinent info, but that still seems to not work, so I give up. Bye.

Great news guys, our light blocker worked almost 100%
It's a cover that slides over the HMZ while in use and straps to the back of your head. Once on corrrectly it blocks almost all light in a lit room, giving you a better experience.
I just tested the prototype for a few hours, and it pretty much blocked all light but needs a bit of work for blocking light at the bottom of the unit.
The experience was much better because I couldn't see out the top, sides or bottom anymore so I acually felt like I am in a private theater. Not sure why, but the image also seemed better, perhaps because everything was so dark.
I'll keep everyone updated, once we get 100% light blockage we will take pre-orders and shipments would begin early August.
Unlike our cushion pads, we wanna be prepared this time and make shipments faster. We were very unprepared for the cushions as we didn't expect to get so many orders! So shipments have been slow for that, as we can only make so many a week due to our jobs. However, since my wifes quitting her job we can get more done and ship much faster soon.

After trying the device a couple off days now i think i am gonne return the sony HMZ-T1.

The comfort is horrible.

A pitty the picture looks great(exept the slightly visible pixel structure).

And the blacks are realy great....

You can mod it to get more comfort however I was never that sasified therefore I passed mine along... I do miss the picture on the HMZ. This is what is holding me back on the ST1080 - it sounds like comfort is perfect however the pic may have issues - the total opposite on the HMZ

I was also thinking of the st1080 but the bad blacks and some more negative reviews is holding me back.

About modding i dont know if it will ever fit great....

I modded mine first with a simple velco strap - made a world of difference, and then I modded it into a welder's helmet - complete with 3 pads that felt I was wearing a pillow - it was beautifully confortable however I found that I was always having to slightly adjust the HMD to correct the pupil sweet spot... it was just not practicle for what I wanted from it.... I do miss that bright beutiful picture on the HMZ though!!!

Maybe i will try to mod it with the GoPro Head Strap Mount..

If that not works i can still return it...

The pic is indeed good with the device...

Its good on animated movies

And normal movies too....

Got sum 3D foooder for the weekend.. Hugo 3D , Underworld 3D . Journey 2 3D and Closer to the edge

today i got the GoPro Head Strap Mount.

But i have no idea how to get better comfort with it lol......

I've had mine for several months. I saw TRON 3d at IM
AX.

Although the theater experience was better with IMAX, obviously with the huge sound track and screen, I think the 3D experience is better with the HMZ. Colors are so vivid, the image looks real at times.

I also notice that the pixel structure, that annoyed me at first, is starting to become less obvious with use, so the OLED panels must have some kind of break in. They are becoming smoother in image the more I use them.

Did you mod the hmz for better fit?

Hi, I recently bought this HMD, but if I connect it to the PC, I can't hear any sound.
I have a GTX580 and the audio comes from an Asus P6T motherboard.
Do I have to enable the HDMI audio device in Windows or what?

Thanks

Right click on the volume icon in your windows task bar, select "playback devices". You should see an option for Sony HMD-1. Select it, right click, and set it as the default device.

It came used with the cloth headband from Bravia 3D. It doesn't fit me perfectly, my profile must be weird, because there is no way I can use it without squishing my nose a bit, and the widest excursion of the eye lenses is just short of ideal for me.

Nontheless, I have become more impressed with it the more I have used it over the last several months because of the beautiful picture, great 3D effect, and it is really the best way to play games on Playstation 3. As I said, I think the OLED panels get better with time, a bit smoother and more luxurious in appearance.

I also really enjoy watching movies on it through the PS3. Standard DVD's that are of good quality look just great, and Blu Rays that much better.

I think I have gotten used to the fit more than anything, it goes right to the correct spot after using it for a while. The included headphones are decent for a theatrical experience, but being able to use my favorite headphones would be a plus. I have figured out a way to use high quality bud earphones through a home theater receiver, but it is awkward.

My cable provider has started allowing 3D movies on Starz and HBO, so I have been hooking up an HDMI cable directly to the cable box and the results on 3D movies through cable are impressive.

My greatest caveat aside from the fit was the obvious pixel structure, which seems to be getting better with time as well, or I am just getting used to it, it does seem smoother than when I got the headset. It was used, but only for a couple of weeks by another user.

really want more pop out on the 3D with the hmz-1, u dont get the feel of how far out he objects get vs a 3D tv

stop complaining about hmz-t1, fix your eyes and switch to pc.
then you can set the 'pop out' aka convergence.

go away with your 3D tv, this is HMD dedicated thread.

Unfortunately it's all relative to the visible landmarks available when viewing an external 3D screen and is not intrinsic to the HMD technology. (Testing the ST1080 with the same 3D sources produced no improvement.) An HMD is the best way to achieve the illusion of the natural looking 3D. The thrill of peripheral vision "pop-out" in real life is not an extra thrill. It's just a natural phenomena taken for granted. You get the same perception with an HMD. The depth is there and it comes out of the screen plane completely to the parallax setting, when there is a negative parallax, but to see that its there with an HMD you would have to additionally look at the black boundary of the image for the brain to fuse the additional plane as a reference to realize it is there for an additional thrill of glory.
