Sony VPL-vw1000 - Page 94

I don't know the exact software programming, but, basically it is software driven. It uses processing to extrapolate the 3 colors for the area you are changing. Somewhere I believe there was a white paper on it (though admittedly it could be different for the 1000 since that paper was for older models). The problem is as it does all this processing, it taxes the unit in general.

Another posted some images of a 10 increment change and a 1-9... On the model Sony he had (and I do not recall) 10 equaled 1 pixel, which actually these panels are slightly larger than the stated resolution, so 1 pixel is an easy shift. Again, not 100% sure if the 1000 works the exact same way, but I do know it is some sort of variation.

From my testing, unless ones convergence is WAY off (in which case you need a new projector) you are better off leaving it as is, then spending hours adjusting since what I found was the benefit did NOT outweigh the cons in most cases. Of course to each his own.

Are those the new UNIVersal they just released? I know the have an RF dongle coming soon. Wonder if I could use those glasses with the Monster rf emmiter.

They have been out for a couple few months...though slowly shipping until recently. These are IR based. They worked well, and for kids were a great fit and fairly inexpensive which is good.

From quick testing the actual Sony ones did work better, but again, target audience is kids and they are not going to likely care.

They are releasing (if not already) an RF dongle option which plugs into the frame of the glasses. I'm curious if they will communicate with the Monster RF emmiter with that dongle. My guess is they should but I'm not sure...

Not sure on that...but once they do we will likely have them and I can check it.

Just hit the USA last week. Should hit everywhere soon. The necessary unpacking and display program has been inside the projectors from the beginning. They've just been slow to release the software for the PS3.

Another option for kids are the Xpand Youniversals (104s). They come in three sizes. The small size is great for a four year old. Mediums are great for seven year olds. They use the built in projector emitter. They're relatively cheap, and I'm pretty sure you can buy them from AVS.

Visually I can't tell any difference between these and the Sonys.

This sounds like something I've seen many times over the years with four different projectors. It always turns out to be the same thing - an unusual piece of reflective dust on the screen itself. To test, walk up to the screen following the reflection for as long as you can. You may lose it as you get very close, but try your best to find that exact spot. Dust the screen off there and see if it goes away - or moves.

Hi Guys. Sorry I have been absent but I underwent some serious eye surgery (burst blood vessel and detached retina) around the end of May and really couldn't use the computer much or even my HT. But things are now almost back to normal (just a tad blury in one eye but that will get better over the next few weeks). As Arnold says in the Terminator, I'm back.

Shifting 10 clicks equals one full pixel and that really has no adverse effect on PQ. You lose one line of pixels, no big deal. Thus 12 clicks is one full pixel and two tenths of a pixel..While 5 pixels is a worst case having the most adverse effects on resolution and focus, the net loss in same for a 2 tenth shift is clearly offset by the convergence gain. So I would have no problem with a 12 click correction but would with a fourteen or fifteen click correction.

welcome back mark..glad it all worked out well...

Good info. What if color B v setting becomes aligned at -20 (2 full pixels off) and color R v setting becomes aligned at -6. (1/2 pixel off). Looks like the -20 is less worrisome than the -6. But when looking at both combined it seems this will be trouble.

If I leave color B at v -20, and if I can live with color R at v -2 which will not be perfect (instead of -6 which is perfect alignment) should I keep it or still send it back?

20 is not a problem. Given the pixel density at 3840 x 2160 or 4096 x 2160, I would not worry much about a 0.4 Red pixel error (the 0.6 pixel error flipped to the other side of the grid line). I suspect that at your viewing distance you could not even see it. I would globally reduce it by say 2 clicks (from 0.4 to 0.2) and just leave the small remaining error. Eliminating it completely would be more of a trade off but the trades are probably not even noticeable given the high sharpness of the Sony and the pixel density. Try it both ways. I suspect you will just fix it completely globally (rather than using multiple zones) and notice no PQ deterioration and that much better apparent convergence.

Ok Mark, I think I got it. Leave B v setting at -20. With color R v setting perfect alignment is -6 or -7, but your saying to adust this down by 2 to avoid being adjusted at a 1/2 pixel,... but wouldn't it be better to round R v up to -8 or -9 instead of reducing it to -4 or -5?

The projector is otherwise sharp with perfect uniformity and to my eyes no motion anomolies caused by software panel alignment. So your giving me a bit of good news. Would you agree that there are risks to an exchange as the replacement unit could bring bigger issues such as uniformity problems?

Thanks for your help.

Hi. I have edited my post. You got it. I would not exchange it but would be perfectly happy with it. I am in the process of getting a new unit from Sony. They took my loaner back that I was using in my work with them to run some tests and I am purchasing one for myself. I miss the beast.

Ok thanks Mark.

Great news to hear that you are mending well, Mark!   We missed you.

+1!

My B isH -17 and V -10. Red is 4 and -4. I am very happy with the pj except random motion issues and the 3D emitter problems that puzzle me. I cant get the 3D external emitter to work at all. It acts like it is working then the picture will get extremely bright, lose sync, then flicker. That pattern is repeated over and over.

I've been talking to Mike about exchanging it but if the alignment isnt the cause of my motion issues then I'd be taking a chance on a worse pj if you ask me. That is also assuming that the 3D problem isnt related to the pj directly. I've tried to capture the motion issues with a video but they are barely visable when recorded. The size of the screen may be why its hard to see the motion problems in comparison since in person the image is so much larger.

My focus issue was just stupidity on my part. I guess I had zoomed before saving the setting and thrown the focus off so that is not an issue.

why do you think you will end up with something worse? Sounds like you're dealing with a few issues now. I'm a little surprised you wouldn't want to exchange it. What's the motivation to keep something that has problems with the emmiter, motion issues and less than desirable out of the box convergence?

Changes are a new projector from Sony will be in better condition. Worse is very unlikely.

Just the advice that says the convergence isnt likely to be the cause of the motion issues. I'm going to try to upload the videos to see if it can be seen on here. I'm not ruling out that the emitter could be an issue of its own as well. But I have put in the request for exchange so my fear of banding, dust blobs, or whatever else is moot since I'll take the exchange if they agree that one is warranted. The motion issues could be a lot worse in other words. Its not like everything I watch is a bad experience. I've put over 140 hours on it already so am enjoying it very much! Any of the other reported issues would be more bothersome than blurring during fast scenes and fast panning. I need to order some monster glasses to rule out 3D issues with the unit itself. I have watched a bunch of 3D but have to hold my head really still for a good signal bouncing off the AT screen its only when I use the external emitter that the obvious problems appear,


See if this works. Not very good quality at all but best I have with phone. Notice the words jumping around once they start scrolling.

And the second video. If phone would ever email it to me it would be larger like the first one.

I would consider the convergence issue acceptable if you had no choice. Bundled with other potential issues you are having, it's a no brainer. Not to mention you keep your original unit for 15 days while you evaluate the replacement they send you. There is no risk.. if you think the replacement is worse send it back. Have them replace it again... Take advantage of the service you paid for. I would not accept compromises when it's not necessary. IMO.

I had no idea about the 15 day deal. Then yes it is a no brainer. We shall see what happens. I can pick up on the choppy words scrolling but who knows if sony will see them, I may have to figure out how to take video with the real camera on a tripod to get better quality to show them.

Hi Guys, i've been really happy with the projector so far but tonight i just noticed a banding problem when watching the Hell on Wheels TV series blu ray. The intro to the final episode (ep 10) has the main character riding across a field and the blue colored sky behind him. The sky bands horribly, like giant contour rings moving across the sky. I tried changing every setting and they moved where the band occurs, but the only setting where it disappeared was by turning on Digital Cinema mode (usually i'm using Reference mode). After noticing it in that scene i started to notice it in more minor ways in other scenes in the same episode.

Can anyone else try that, if you have that series? I had not noticed it on any other source material, and i haven't had time yet to try other source material. I have 30 days to decide whether to keep this unit (it's B-stock), and i'm on day 28 (better than day 31 i guess!). An hour before noticing this i bought the 4 year extended warranty 'cos i had had no problems at all with the unit.

I guess tomorrow evening i'll try out some more material to make sure it's not happening everywhere now i've noticed what to look for.

Once again, i did try changing every setting available in Reference mode, iris on/off, color temp, black level etc, all those changes did was move where the banding was in the sky, that indicated to me that it's not a disc issue but some digital processing artifact.


Thoughts? - and please, if anyone else has that blu ray (quite a fun series), can you give it a try?

Have you put up a white field pattern at 75 to 100% from a calibration disc? Ie the downloadable AVS HD 709 disc? This is a good way of checking for uniformity issues.

Could you let me know where you got your 4 year extended warranty? I thought an ES projector has a 3 year warranty so does your warranty cover an additional 1 year or an additiomal 4 years after the Sony warranty ends? Thanks
Edited by G-Rex - 6/28/12 at 3:52am

Hi G-Rex, thanks for the reply. The projector is b-stock so it only has a 30 day warranty, that's why I got the extended warranty. I got it through Sony on the phone, they offer 2,3,4 year warranties for b-stock purchases. The warranty is transferable (i think all ES series warranties are) . Btw, you can now find the ES series products on the Sony style site, but you have to enter the model number (just enter ES in the search box), i don't see them via the menus.

I haven't tried a calibration disc yet, i used the settings posted by projectorreviews.com in their review, and it had looked great at everything until that one disc yesterday evening. More than anything i was just wanting to check if this is something specific to my projector or whether other people have noticed it - if other people have then i think an exchange is pointless.

Mark - How long before the new beast is expected to bring new light to your HT screen? I trust your eyesight will be back to 20/20 by then and you will let us know how, or if, the new unit's performance differs from the loaner.

The weird thing is, on the Sony Style site, in the upper righthand corner, there's a badge that says 5-Year warranty, but below, it states a 3-Year Limited warranty...

Does Sony let non-B-stock customers extend the warranty?

I forgot to make mention here, not that I've been able to view it, but I ordered I got my usb stick of 'Timescapes' 4K. One thing to note about the quality of shipping is that it must be the filmaker himself sending these out! Mine arrived in a basic envelope and it was nearly falling out of a tear in the back of it. Looked like a kid had posted it..

Now if I can just get my latest HTPC up and running after weeks messing around and having to in the end buy a new Sandybrige-E CPU as something was wrong with my original brand new one. Now I've got an issue getting the darn machine to boot off any kind of device, let alone it's ready to go Windows 7 hard drive. Seems almost like the bios is corrupt as it just goes into permanent cursor flashing limbo after clearing initial power on post, no matter what device is selected to boot from, DVD, bootable USB, etc. So I'm now going back to my first identical rig that I'd thought had a bad motherboard and going to try to get it to boot properly with the working CPU I now have. In building PC's from scratch for over 15 years, I've never had this kind of drama with a straight forward Shuttle barebones PC out of the box like this. Hopefully all going well I will also add a small SSD drive solely for 4K material playback and perhaps be able to view Timescapes on the weekend properly.

And yet.... he was still able to hang a 240 lb. motorized screen with one eye!!!

The guy is Superman- I'm tellin' ya!



nice to see you back!
