Yes that is true as well, some models and of course their condition, will determine if they would be able to display the differences in the 2 inputs.

There is no notable difference between ports 3 and 5 on mine.

That's right there should be little or no difference between those ports on anything from 808 to the 909.
The port 3 board R7621055 is the same part number from the BG800 to 909 and everthing in between but the quality of the board has changed. There was a difference between the Port 3 and Port 5 on early models as port 5 was not as well designed as it is in the later models.

I know, i just do not have the right equipment to make these cables. (crimping etc)
There is 1 difference between Port 3 and 5, using a BNC to BNC connection you can keep the 75 ohm impedance while the port 3 offers 50 ohm and the sub-d connector isn't ideal for the impedance either. Offcourse this does not really matter if you use a VGA to BNC cable since the VGA end isn't ideal either.
stridsvognen you have a VP50 - C2 3800 both with analog out, maybe you have to compare these? You would need a moome external though :s

I also have a Lumagen HDQ a VP30 and a Calibre Vantage HD2 all with analog out.. 
And all works with 1080P60hz out, when HDCP is strippet at the input signal. So only reason to get a EXT moome is to test and write about it here..

That's why you need one 
Use 1 source, put all the Vp's in passthrough mode so they only do Digital to Analog and make screenshots!
Maybe someone can lend you one? I would if i had one.

You know thats a damn lot of work, to calibrate the source and projector each time i change, not 2 concverters have the same output i guess.
And the moome is a bit tricky getting setup with the right gamma and levels, to make a perfect gamma run out of black, that is ideal for the projector.
And those 2 guys down under, already did all that and say the moome is junk, so it sounds a bit like waste of time.
Ill not be able to compare details if the calibration measurements is not the same with all converters.

True, you just seem like the ultimate candidate since you have a lot of scalers

I doubt it will be posible to ilustrate the differences with screen shots,
I have some old shots from before i had the radiance, first 2 shots are with HDfury3 HDMI out of my VP50.
Next shots must be with the moome int.

If you guys have Scalers and want to run RGBHV to your Barcos then get the Moome MUX it will output the native 1080p@24 and then the scalers will do what ever you want.
I still say it is the installation on the board that is the issue and not the Ext HD it self. I have had at least 8 moome products and have not had an issue with any of them. Scoped them all at my marquee's VNB. All look great noise wise.
I have also had a few HD fury's come through my doors the first version did its job but not well, and the 3 was not better than the moomes. Ask Craig. I have not had a 4 though so maybe now it will be close.

I dont use H shift.
I didnt say the HD F 3 was better, but i will say its just as good image wise, not compared to the internal, and not compared to the computer.
All the tests i did used the same cables, 2x HDMI cables of different makes, and tried RGB with a few different cables and configs, PC came out on to there easily every time.
I built a new machine last night for someone else and will probably do one for myself soon too, X79 chipset, 32 gig RAM, GTX 760 4gig OC video card ( can you believe they had Windows 7 home premium on it and it soft-limits RAM to 16 gigs? )

I don't belive that's the issue as I have another DAC that uses port 3 from the back of the projector that produces a sharper image at 720p/60.
There may be a better results at other resolutions or frequencies so perhaps it will live up to its reputation but right now it seems very ordinary to me. |
Can you post some 1:1 720P pixel resolution screen shots, so we can see the difference.?
And some normal movie screenshots to please. |
Please..!!!

I'll post a few normal screenshots from my Marquee 9500, and later tonight or tomorrow night, I'll also post several 1:1 pixel resolution shots of 1920X1080P and even higher resolutions.
I'll have to better dial in my projector. Since firing it back up, I changed the focus board.
1920X1080P 60hz on an 8' wide screen.

Mike.. Nice shots. Any chance you have a EXT moome you can compare to the INT and comment on the difference.?

I don't have an EXT version of the Moome, but could do a really good comparison of that version to the internal Marquee, if I had one here.
