Directly into my SP-A900B or routed through the Radiance VP there are no bars being clipped.

Im direct too, on all sources, via an RTCom matrix switcher. I have a second Oppo going in, so I'll let you know.

After spending $$$$ on the Lumis isn't the scaler in the host as good as any outboard scaler you can buy? Is the picture quality that much better from the host scaler?

I am very interested in just going direct to the Lumis, and just use my receiver (Arcam AVR600) for audio. What are the best options here? I had been thinking a video processor would make sense, as that ought to provide better processing than the AVR600 (and should presumably also eliminate the green vertical line I currently have when going through the Arcam), but a matrix switch sounds even better. Any recommendation? I currently have 5 HDMI sources...

Those 2 sentences seem at odds with each other. If you could clarify, Ill try to answer.

There are reasons why some people may use an external VP, I personally dont. Scaling is not something that requires one. The scaling is as clean as a whistle and is fully variable and programmable in both axes. The VP software on these machine is actually written "in-house", and is way ahead of other on board VP.

My experience, and that of many others, has been that external VPs can actually be detrimental.

Dont waste your money on a VP just to hook up your sources. The 600s VP is OK, but you will get a cleaner image direct. I don't go via my 600s or 888s.

In your case a matrix switcher is the way to go

I'll get back to you on specifics. The only problem with matrix switchers is that, above 4x4, they get expensive quickly.

Any idea on a max budget, or dont you care? A 2(or more) output distribution amp may also do the job.

Are all your sources HD?..........(forget the Wii, via component, for now.)

From some of the post I read it sounded like people were having problem with their outboard scaler when used with the Lumis host. My question is why would you need an outboard scaler when there is one in the host? Thanks for your answer Coldmachine.

Thanks!! Here are my sources: Tivo HDXL (HD), HTPC (HD), Kaleidescape (not HD), Oppo Blu-Ray (HD), Wii (Component -- not HD), and the Arcam, for Setup (not necessarily HD).

Price is not a major issue, but I would wonder if it makes sense to spend more than it would cost for a DVDO Edge and then just use that for switching -- I can perfectly understand that it would make sense, but would like to understand why.

Thanks for all your help!

You could use a 5x2 distribution amp, Octava do one, and i think its only $300.

That way, you can use the Arcam to convert the Wii to HDMI. One output to the PJ and one to the Arcam for audio. Do you get the line with the Wii?

A matrix will allow you better flexibility. i.e. you could use a small TV as a monitor to save using the PJ for audio adjustments etc.

Really? As expensive as this projector is, I would have still thought a high-end dedicated VP like Radiance should have offered superior scaling and upconversion.

Yes really. The subject has been covered here many times.

The expense of the PJ is not relevant per se. The same software core is used across the range from the D80e upwards. Its been developed over a while and gets continually updated.

Its the same with lamp performance...they use the same lamps as others but they get them to fade far less and last far longer.

There are many more things to a good PJ than ever makes it onto a J6P spec sheet.

Yes, pastelly whites are a sure tipoff that your contrast is peaky and set too high.

Coldmachine, it looks like you had just mentioned a matrix switcher earlier but I cannot find it now. Have you done extensive testing of matrix switchers? I have a Classe SSP-800 whose original board DAC I just swapped out for a new dual DAC that the company offered for the latest codecs and although it does not contain the video switching component of the processor my subjective impression was that my video suffered a dramatically softer picture as well as the dreaded clayface. While I need to do more testing it was fairly obvious but there's not logical reason for it, although I suspect that there may be more current draw from the DAC board which somehow is affecting the video.

I've got to find a workaround and the matrix switch seems to be the ticket. Are there significant differences between them? I'm only interested in keeping video quality tip top and am going to keep the SSP-800 as the upgrade was crazy good improvement in the sonics.

If all you are trying to do is send a signal to the PJ and your Classe, you may find that a 2 output distribution amp will do the job. You can do 5x2 inexpensively.

If you do need a proper matrix, how many ins and outs do you need. That will have a major bearing on the price. 4x4 is cheap, but when you go over that the cost increases exponentially.

Any where from once every 1-3 minutes to once every 12-15 minutes, the scene will flash bright. On average, this happens a total of 15-20 times per movie. I have never noticed this with Blu Ray movies, only DVD... which is why it took me so long to post this. Lately I have been watching a bunch of 'art-house' films/indie films on DVD. It is disrupting to the movie. Thankfully I have never noticed this effect on Blu Rays.

The interesting fact is that is not related to the changing of a scene. the scene is 'static' so it is not a transition for a bright to dark scene or such. It is as if the dynamic iris has a hiccup. Why only on DVD makes this very interesting problem.


I saw this tonight for the first time.

I watched my first DVD tonight and noticed this as well. I am using an OPPO 980 DVD player set to 480i output over HDMI. Got a random flash every few minutes as exactly described above. The flash seemed random - not in a dark or light or transitional scene.

I recalled this post during the movie when things were flashing. It was not subtle and my 12 year old asked what was going on. So, I stopped the player and changed the output resolution 480i to 1080P60. This eliminated the issue completely. I couldn't tell whether Health Nut figured this out or not as a 480i issue (but I saw in a later post that he did not notice the flashing with 1080i).

Not that I output 480i very often, but it is a bug that I can confirm along with Health Nut. I have the latest software. I have never seen this with Blu Ray or HDTV. This may be a 480i only issue / bug.

Thanks for postingg Jeff. I reported this to Sim2 a few weeks ago as well, and they are "looking into it."

Thanks Jim... Did you determine it a 480i issue or give them direction as to where to look?

Ok, so it is the 480i output over HDMI via Oppo players causing the random bright flashing. I'm using the Oppo Blu Ray player BDP 83 and Jeff is using the Oppo 980 DVD. The whole advantage of sending the 480i output is to let the superior deinterlacing and scaling be done by the Host. This sounds like it should be a fixable problem with a firmware update, once Sim gets confirmation that it is a 480i issue.

Should be a simple fix. I don't think it is an OPPO issue... but a 480i issue as all other OPPO resolutions are fine. None of my other players will output 480i, so perhaps others here can test other brands @ 480i over HDMI? For now, 1080P60 from the DVD player looks good and works well.

On another note, I have a couple opportunities presenting themselves: a new rental property, and a lot where I could start building a house. If things go well over the next several days, I could be moving into a new rental house next month ... and in one year, a lot/new contruction house (where I would have the ability to design my own theater room, something on the order of 23.3' x 35' x 14' sounds about right--using the 0.67:1:2.5 golden ratios for acoustics)

On that note, I'm looking to go to the largest screen size possible with a Lumis using a matte screen, Studiotek 100 non perf. I'm afraid to push it to 13' wide (2.37 of course). I was thinking 12.5' wide? Opinions? I really love the purity of the matte screen. Is 12.5' wide too small for a 23.3' x 35' x 14' room?

We need Sim2 to look at 480i over HDMI. I bought the Oppo specifically for the ability to output 480i to the HOST. Although there are a bunch of other players capable of 480i over HDMI as well...

I am using the Oppo BDP-83 480i HDMI to my Lumagen Radiance XE outputting 1080p YCrCb to my Sim2 C3X 1080 with no problems or random bright flashing issues. Haven't tried it direct from Oppo to projector though.

You wouldn't have an issue. This only seems to occur with a direct 480i input into the projector. Send a native 480i HDMI signal to your C3X and you'll know for sure. It may be related to the dynamic iris (so you may not have the issue)???

When I owned the C3x1080, I had no problem with 480i from the oppo DVD player. I sent 480i to the C3X 1080 with no issue...

I had to shut down the Host today using the hard button as the menu would not come on from the host soft buttons or the remote.
By turning off like this the bulb cool down did not take place.
Turned on later by pressing the hard button on the host and everything works fine.

As we learned a couple of weeks ago, that's the latest firmware available. Given the issues people are experiencing it appears a new version is needed.
