ViewSonics 3D DLP (720p/120hz) HDMI 1.4 converter - Page 2

I noticed you said you use a PC for 3d blu ray. Are you able to run the PC through one HDMI input and the cable box through the other input? In other words does viewsonic box allow pass thru of the full frame 3d signal? I am considering getting one to use in my setup but I want to use a 3d bluray player for movies and nvidia 3d vision for 3d computer games

I also couldn't get ESPN 3d to work due to T/B 3d. Where did you find the rebate for the free glasses?

Have you contacted Viewsonic support to see if they have a fix for the T/B issue? I hope they will have a firmware fix.

What T/B issue?

HDMI 1.4a 3D format720p 1280 x 720 60Hz Top-and-Bottom in the viewsonic list of supported 3D formats is broadcast in a 1920x1080 2D buffer since it is a 1/2 R format.

I think you mean a 1920x1080p 2D buffer, but cable can't do 1080p, just 720p from a 1080i signal--so something gets lost. Side-by-side works because the Viewsonic looks for a 2D 1080i signal. I could be wrong of course--help me understand more about this. I want to get Viewsonic support involved, but I don't know how this all really works.

I have not tried to do pass through, but will try it sometime this week.

Cable can very easily download 1920x1080@60 2D buffers since that is how all the ATSC and cable 1080i/60 broadcasts are transmitted.
the HDMI 1.4a 720p 3D TnB format consits of two fields, each of which have every other row2 deleted the top (left eye)field is 1280x360 field and the bottom field(right eye) is also 1280x360. The 3D TV then upscales each of these fields to z 1280x720 frame and then upscales them again to 1920x1080 of the 3D TV if that is it's native resolution.

For some reason the Viewsonic doesn't do it and that seems like a major flaw in the firmware.

What is your reference that the Viewesonic does not suppor it since page 8 of the previouly provided link previously provided says theat that the do"

Hi

Page 7 of that doc suggests it doesn't support 1280 x 720 @ 120hz on its input. This is a requirement of nvidia vision. The nvidia card won't kick in to 3d mode properly without it. The pc support seems to talk about SBS only.

That said it still might pass the signal, passing through that refresh rate just might not be documented. If it doesn't its not the end of the world, just get something cheap to share the projectors input and you can maintain the pc's direct connection. Adds a touch to the cost and complexity admittedly.

I tried extensively last night to get top/bottom to work with cable. Alas, nothing worked. I tried all formats, switched off and on, pushed buttons and nothing works. Side-by-side works great, and while it's less than true 720p resolution, still looked good on my ACER. I read more about top/bottom and SBS and it appears that all sports is in top/bottom since it handles motion better and all movies, etc. are in sbs because it's more universal. So sports is not a big issue for me, so I can live with SBS only from cable and blu-ray from my PC, just a pain to plug and unplug to get each setup properly.

Oh, and pass through for cable is no problem and looks fine, but I also have a Mits 3800 for 1080p and watch most cable on that, so that's the plug and unplug issue since I don't have a switcher set up yet to handle it all.

Threed123, did you try change the output of the cable/directive box to output 720p. Sorry if you already did.

If you have 1280x720@ 120Hz form Nvidia Version you have no need to use a Viewsonic converter to convert some other format to it you can just use it as is.

ESPN-3D provides it's ISPs either 3D HDMI 1.4a 720p TnB support or 720p SbS. Comcast uses 720p Tnb and DirecTV provides the non mandatory 720p SbS support which some TVs such as Sony 3D models.

I tried all output formats include 1080i, 720p, etc. nothing worked. I had to output 1080i for sBs to work, though.

Your cable company most likely supports the following HDMI 1.4a 3D formats
1. 1080i SbS for 3D channels other then ESPN-3D
2. Either 720p SbS 720pTnB FOR ESPN-3D channels
What is your cable company?

Does everyone know about the rebate for a free pair of glasses with the purchase of a VP3D1? Purchase must be 5/1/11 thru 6/30/11. Check out the J&R website and search on VP3D1

threed, do you have a receiver or video processor between the cable box & the viewsonic? You may need to set that to 720p as well.

I'm with Comcast, and others have problems with as well. I am running an hdmi cable straight out of the Comcast cable box in the VP3D1.

Yes but there's only one HDMI input on nearly all 720p dlp projectors isn't there? On that basis it would be good if it could also pass a raw unprocessed signal when required. The 3dxl doesn't do this either. It's annoying. Some of us have been watching 3d blu rays on a htpc for a while but want the converter box for other devices like game consoles. Its not like we are just going to stop using our htpcs for 3d. The ps3 for example is not as good a 3d solution for movies aka no HD sound.

Yes having to use a remote HDMI switch would be a nuisance.

So does anyone know if the Optoma 3D-xl also has this problem with ESPN 3D when broadcast in the TnB 3D format ?

Well the sBs and TnB issue is bigger than I thought with Comcast. I explored more movies and found that much of the newer stuff is now in TnB, so basically, going forward, the VP3D1 is more useless than I thought it would be.

I sent an inquiry to Viewsonic support, which stated they would get back n 24 hours, but it's been well over that and no response yet.

I'm using the 3DXL with a Optoma HD700x/HD65 with Comcast and no issues at all aside from having to get off the couch and hit the SBS button to switch formats. It has no problem with the Over/Under that ESPN3D uses and also some of the On Demand programming. I just purchased it this week and it shipped with the firmware needed for over/under.

Hi sdolen;,
So does the firmware update have a read-me file that specifically says the over/under issue has been addressed and fixed.

I only ask because reading this thread and the web in general, it sounded like ESPN 3D started sending out both a side by side and over/under feed to the cable companies and the cable comanies decide which they want to broadcast, side by side or over/under but not both.
I just wanted to make shure your cable company is not just one which chose to send out a side by side feed and the Optima 3D-XL is not really converting an over/under feed.
Thank you for the reply.

threed123,
Thank you also and please post the information here.
I am close to buying and love the Viewsonic VP3D1 price but I want to view ESPN 3D or if somthing else I want to view just happens to be in the top/bottom format I want to be able to see it.

The firmware was factory installed so I do not have release notes, there is some info in the 3dxl owners thread but the download listed there does not have a notes either. What I can confirm is that when I put on ESPN or any other TnB Format that it is blatantly obvious in my setup, you see two images, one on the top 50 percent of the screen and one on the bottom. Not until you physically press the SBS button on the 3dxl twice do you get a usable 3d image. Same goes for SBS content, you get one image on the left 50% of the screen and another on the right and you have to do the same thing, hit the SBS button on the 3dxl but just once. Waiting on a bunch of 3D blu rays to arrive to test with my HTPC using a GT430 and TMT5.

sdolen,
Thank you so much for your time.
I have criss crossed this question and my postings in the 3D-XL and Viewsonic VP3D1 threads.

I found the point in the 3D-XL thread with the firmware file and another point with instruction to install it. From the thread it does sound like the over/under issue is fixed on the 3D-XL.

So from all that reading it also seems that if the Viewsonic has some way for it's firmware to be updated that it should be doable.
I mean if Optoma did it, can't Viewsonic write a firmare update to address this issue ? Looks like Optoma wrote the update months ago.

From the Viewsonic website but you owners know this anyway.
"Inputs: USB 2.0 Type A (service/firmware upgrade)."
So the Viewsonic VP3D1 has the port, they really should release an update.
Does anyone other than threed123 have some information on this matter ?

So..I just recieved my VP3D1. I have it set up as follows:
Samsung Bluray, xbox 360 running in to my Onkyo 608.
Output from Onkyo to VP3D1.
VP3D1 to Optoma HD66.

3D Bluray looks awesome.
I cannot, however, get the Xbox 360 to work. I set the 360 to 1080i (I had to do this with the bluray as well) and I can see the side by side picture. When I press the SBS button, it will not light up and convert to 3d. Any suggestions as to a fix? Thanks.

Fixed it.. Output on Onkyo had to be set to 1080i.

Has anyone tried accessing the 3D channels from Directv using the VP3D1? Does this work OK?
