Sorry my mistake when I said top bottom, I was actually referring to 1920 x 1080p 24Hz frame packed from Oppo bdp 93
being sent out of Radiance as 1280 x 720p 96Hz frame sequential.

Hey, did you try 1080x960p with a Bluray FP source? Did that work for you?

Same problem as above, glasses will not sync although changing delay can get them to flicker.


I took another look and my SKY 3D source and I am pretty sure the problem is only in the right eye. Looking at the left image with my right eye closed everything is smooth. Looking at the right image with my left I closed everything is a juddering mess. I have also noticed a bit of cropping occurring at the left hand side of the image.

Alan

I just messed around with this for the past hour+ and just when I was about to test I lost the picture from the XE. Now all I get is black screen even after a power cycle.

I am over this beta and am going back... no more time to wast, but I really want to see 1080 Twisted Evil

Just ordered one, I'll keep you posted

Alan,

What happened with this? I really want to know because if emitter is better than the 3dtvcorp one I will pursue getting one here for testing. Please let me know!

Also, am I remembering that you are running a Sony G90 as well?

It has not arrived yet. I am starting to get worried as usps tracking has not updated in over a week. I know it was collected from the supplier but nothing has happened since.

Post Office and Customs at the UK end don't know anything about it.


I have contacted supplier for help, currently awaiting a response.

Yes, I suspect I am the only one mad enough to be trying this in the UK at present.

I have 4 3D Sources :-

Oppo BDP93 for Blu Ray, 3d 1920 x 1080p @24Hz frame packed outputting to 1280 x 720p @ 96Hz frame sequential
PS3 for games, 3d 1280 x 720p @ 60Hz frame packed outputting to 1280 x 720p @120Hz frame sequential
SKY 3D Satellite STB 1920 x 1080i @ 50Hz side by side outputting to 960 x 1080p @ 100Hz frame sequential
HTPC 3d 1280 x 720p @ 60Hz frame packed outputting to 1280 x 720p @120Hz frame sequential

Alan,

If you are interested in trying the G90 Vsize mod, let me know and I can send you the details. You need to be able to change four surface mount resistors on three different boards; DA, DE, and DF. It is a pretty easy mod.

I will also be willing to do this for anyone who wants to ship me their boards. Cost will be $95USD plus shipping both directions. I will probably write up a procedure and post it on my web page as well.

In any event, this allows the G90 to deal with 500ish Vblanking lines. This really reduced ghosting to very minimal levels Smile

yes please, that will keep me busy while I wait for next firmware and my new emitter

Is this a global mod ?

In other words should I reduce my vsize in current memories before performing the mod?

thanks

Ok, here is the info. The mod is global, but due to some cleaver thinking its affects can be made not global Wink

Basically JohnHW looked at the schematics and shot over an idea for a mod that he thought would work. His idea altered the Vsize Course adjustment amplitude to make each click have a greater effect on the Vsize.

What I decided to do instead, was alter the Vsize Fine adjustment. I did this because I do not use Vsize Fine for G90's unless they are part of a stack or blend. We do not need the Vsize Fine adjustment for single G90's. For example, it does not matter on a real world setup if the overscan on screen at the end winds up being 0.025% or 0.005%, such fine adjustment is not required.

Thus after the mod, if your Vsize Fine had been set to 128 (really 127 is null), than none of your existing memories will be impacted at all Smile

At present I have the following changes:

DF Board
R2 was 100k changed to R2=20k
R44 was 100k changed to R44=20k

DA Board
R460 was 100k changed to R460=20k

DE Board
R69 was 100k changed to R69=13.6k

This ratio allows for Vsize Fine to have even greater range than Vsize Course. When I apply the settings I set Vsize Course to MAX and then raise Vsize Fine as needed (right now I have both at MAX). I tested the Vbias voltage running MAX/MAX and it looks fine. I have also taken temp readings of the vertical deflection amps before and after the mod, and there was no increase in temperature. This resistor ratio also maintains the other reference wave forms associated with the circuit such as SAW and others (this is important because you don't want to wind up with a twisted image due to improper resistance values).

I am hoping to go back and mod again to actually get just a little more stretch. I'm going to try some even more aggressive resistors because I think this will be useful when the Lumagen FW is released that allows 1080x960p (for now these values are perfect).

But I tell you what. Combining custom vertical timings with basically unlimited vertical stretch in the projector has totally changed the game. I have insanely little ghosting at this point. The improvement is just huge.

One thing I noticed is that the picture is quite a bit dimmer with the enormous vertical blanking. This makes sense because the beam is only actually in an active pixel area 50% of the time. So expect to have to turn up brightness and contrast (or bias / gains). Don't worry as this is not actually putting more energy into the phosphors, it's a more powerful blast but for a shorter period of time.

I was also worried about the possibility of flicker with so little time of the beam striking phosphor. However flicker is still not a problem at all Wink

thanks Craig,

I just pulled the boards to make sure I could find all of the resistors.

I'll get the resistors ordered up and will take it from there

Craig,


My supplier does not have a 13.6k but can supply 13.7k

would 13.7k be acceptable or could it introduce a geometry distortion elsewhere?

alternatively I could piggy back a 15.8k on top of the existing 100k effective resistance would then be 13.64k (if my calcualtions are correct)

what would you suggest ?

I would piggy back the two so that you don't even have to bother to remove the originals. Also, if you are ordering you may want to get some 10k and 6.8k chips. I dropped those in the mule yesterday, and it ran fine for many hours with no temp increase again. The V stretch is crazy with more than is required. I am probably going to switch to the lower values on the theater projector before the new Radiance FW comes out.

Word of caution on the G90 Mods to increase Vsize!

Be sure to turn off ABG before you V stretch out the image. I think it only wise to make sure that you don't run the AKB line across the bell of the tube every time you fire up the G90. Tube could possibly implode quick!!!

I will actually test this on the mule and see if I can make a tube implode Twisted Evil This mule gets torn down in a few days anyway.

My emitter finally arrived today after its little holiday with UK customs.


First impressions are very good. It has a very strong signal which means a wide range of effective seating positions. At last I have an emitter that syncs with my Samsung SSG-2100AB glasses.

I tried my old Samsung SSG-1000 glasses but could not get it to sync properly. I tried the 3dtvcorp type N universal glasses and got exactly the same results. In my setup at least it would appear that the Gen2 emitter and type N glasses respond to the old Samsung format. I don't understand how Craig is getting them to work but I'm glad it does so great.

For me the 3DFlightsim Samsung emitter is a far better proposition than the Gen2 one. I wonder how JohnHWMan is getting on with his Gen2 emitter ?

I only got a chance to try BluRay 3D tonight and found that with a delay of -2.1ms and running about 470 lines of vporches I get a completely ghost free image.

This is very encouraging

Hello Alan,
I'm still not got my SSG2200AR glasses from Ebay seller in South Korea. I've started a dispute on Paypal as it's about more than a month of wait ... In between I'm currently shasing those from other sellers (germany) on the bay and win one pair recently. I should be able to receive it in a week or so.
Because of this missing parts, I still not tried the 3D on my G90 yet. Sorry for the delay...

I'm also hoping to have the new XS+ 3D firmware (with FPGA upddate) that enable complete 3D custom RES before I start playing with these new toys Wink

Thank you for this information Alan. I ordered one of the 3DFlightsim emitters yesterday for testing based on your good results Smile

Also Alan, if you are happy with 470 blanking lines on the vertical than good for you. However, I have found that the longer I watch the more easily I can detect ghosts and blurs. Now this may just be because I got used to looking for them and have trained myself to spot ghosts and other 3D artifacts in this development project and I have spent months looking for problems instead of watching movies. But there are definitely ghosts with 470 lines as I am running 550 blanking lines now and there still is mild ghosting. It is a trade off so just do as you like and stay happy Thumbs Up

I am very glad to hear that the new emitter is working well for you!!!

Get on it John!

Seriously though, the new FW form Lumagen should be any day. Pat posted that beta that I later suggested he take down due to bugs. But he and I talked this past Friday and he was going to send me another Alpha FW version that evening if it was ready for Alpha testing... it never came from him. Thus I can only surmise that Pat is still finding serious bugs that make the FW unusable at this point.

But we know Lumagen and Patrick and I am sure he will have this all worked out soon Thumbs Up

Also I have converted a BD3D disc into a 1080p 24Hz SBS 3D file. I used DVDFab Blu-ray 3D to 3D video ripping software on the highest quality settings to create an M2TS file. When the new Lumagen FW comes out this should be watchable from my DUNE Base 3.0 media server or other file player like my Oppo BDP-83 or BDP-93. The native resolution of the 1080p SBS is of course 1080x960p which will match the new output mode when Pat gets the FW so the only scaling that will take place is during the original conversion from FP to SBS. By all accounts, the scaling and re-compression in DVDFab is top notch and I made the output file 20 gig which is exactly half the original file size. I expect that this should look about as good as the original (especially wearing 3D glasses).

This is fun Smile

I am seeing varying results in ghosting depending on the source material. On some material I am seeing no ghosting at all. on others I get ghosting but not just at the bottom of the image where I would expect it due to timing issues. Some of the sky 3d broadcasts are stunning, I am desperate to get my hands on the next side by side firmware Smile

If I run flight sim X using the weight shift microlight there is a solid vertical bar down the middle of the screen (vertical pole on the microlight). part of this pole is dark but part of it is white. The white area causes some ghosting no matter where it is on screen. muting the green tube removes the ghosting completely.

I therefore conclude that this particular ghosting is due to slow phosphor decay on green when the tube is run with high output (bright areas of the image). I am using P19LUG tubes. On my G90 at least it would appear that timing issues alone will not completeley erradicate ghosting with some program material. However it is currently very watchable and probably only people who have been watching too analitically (ie us) would even notice the problems that we are now cursed with seeing so easily !

The white area causes some ghosting no matter where it is on screen. muting the green tube removes the ghosting completely.

I therefore conclude that this particular ghosting is due to slow phosphor decay on green when the tube is run with high output (bright areas of the image). I am using P19LUG tubes. On my G90 at least it would appear that timing issues alone will not completeley erradicate ghosting with some program material. However it is currently very watchable and probably only people who have been watching too analitically (ie us) would even notice the problems that we are now cursed with seeing so easily !

I totally agree on all your points! The picture is completely watchable and looks fantastic 99% of the time. But if you know what to look for you will find a ghost here and there. It is also much much much easier to see ghosts in static images be they paused BD or 3D pictures.

I said several posts back when I was working on this technique that I thought we had about reached the limit of what this green phosphor can do. I think it is great and most everyone will be totally satisfied. This was proven at my CRT meet two Saturdays back... no one who attended was disappointed and everyone thought the image was fantastic. The consensus was that my G90 running 3D looks better than the IMAX in a theater so...

I may still try a P43 green, but I don't see many if anyone switching to P43 just for this minor improvement. I don't think I will switch to P43 permanently, but I do want to try it.

Me too Craig ! The P43 Green can improve the VBW on the G90 as it would not require to mod the G90 VZISE adjustment circuit and remove the need of 500+ extra blanking lines. Then, we may be able to do 1920x817p96 from 3D 1080p48 2.35 AR material and maybe 1600x900p96 for 1.78 AR material and stay within an acceptable Projector video bandwidth Wink .

Craig,
Have you had a chance to play Tron Legacy yet?....I picked it up last night at Best Buy..They had it for $22 w/coupon. I try to stay away from BB at all cost...but the deal was too hard to resist.

I'm going to watch it tonight on the DLP....The previews looked great...It should look way better on the G90 better because of the great black levels lack of RBE.

Man, I am now jealous Wink I have ordered a 3D copy of Tron from an eBay seller, but it is the 3D disc and cover only (no 2d BD, DVD, or DVC discs). I paid $20 shipped and I don't even have it yet. I would have loved to have watched that last night instead of Skyline. Oh well, my copy of Tron will be here in a day or two because at least he shipped it on the release date yesterday with tracking info.

BTW I don't get it. They guy I bought Tron from sold like 100 NEW copies this way on eBay (3D disc only). What do you suppose he is doing with all those 2D BD, DVD, and DVC discs. It can't possibly be worth selling each separate on eBay can it? I mean to sell a $20 item on eBay winds up costing close to $3 by the time you get through all the fees.
